Total carbohydrate mobilization and crude protein content of adesmia bicolor (poir.) dc. crop under phosphorus fertilization

En la región árida-semiárida central de Argentina la disponibilidad de biomasa de los pastizales naturales en el periodo de bajas temperaturas es escasa, por lo que es importante lograr una mayor producción de especies forrajeras de crecimiento invernal. Entre estas especies se encuentra Adesmia bicolor (Poir.) DC, leguminosa perenne, de ciclo indefinido, herbácea, con crecimiento clonal, lo que favorece su persistencia bajo pastoreo intensivo, y una elevada capacidad para fijar nitrógeno (N). Existe escasa información respecto al comportamiento de este cultivo bajo fertilización. Por tanto, el objetivo de este estudio fue evaluar la producción de biomasa, contenido de proteína bruta y movilización de carbohidratos totales de A. bicolor bajo fertilización con fósforo (P). El ensayo se llevó a cabo en una parcela con A. bicolor en cultivo ya establecido. El diseño empleado fue de bloques completos al azar con tres repeticiones. Los tratamientos aplicados fueron tres dosis de fertilizante fosfatado líquido: Tratamiento I: 0 kg ha-1 (control); Tratamiento II: 50 kg ha-1 y Tratamiento III: 100 kg ha-1. Se realizaron seis muestreos cada 60 días en los que se determinó: biomasa aérea y subterránea, porcentaje de proteína bruta y concentración de carbohidratos totales. Los resultados mostraron que la mayor producción de biomasa se obtuvo con la dosis de 50 kg ha-1, el contenido de proteína bruta en biomasa aérea y subterránea fue similar en todos los tratamientos y el patrón de movilización de carbohidratos no se vio favorecido significativamente por la aplicación de P.In the arid-semi-arid central region of Argentina, biomass availability from natural grasslands in the period of low temperatures is scarce, and therefore achieving a higher production of winter-growing forage species is important. One of these species is Adesmia bicolor (Poir.) DC., a perennial herbaceous legume with an indefinite cycle and clonal growth, which favors its persistence under intensive grazing and high capacity to fix nitrogen (N). There is little information about the behavior of this crop under fertilization. Therefore, the objective of this work was to evaluate biomass production, crude protein content and total carbohydrate mobilization of A. bicolor under phosphorus fertilization. The experiment was carried out in a plot with an already established A. bicolor crop. A randomized complete block design with three replicates was used. The treatments consisted of three doses of liquid phosphate fertilizer: Treatment I: 0 kg ha-1 (control); Treatment II: 50 kg ha-1, and Treatment III: 100 kg ha-1. Six samples were collected every 60 days, and aboveground/ belowground biomass, crude protein and total carbohydrate content were determined. The results showed that Treatment II (50 kg ha-1) recorded the highest level of biomass production of all the treatments, whereas the different fertilizer doses did not affect crude protein content of aboveground/ belowground biomass or carbohydrate mobilization patterns.Fil: Gorjon, Juan.

Ensayos preliminares para determinar la fijación biológica de nitrógeno de Adesmia bicolor a través del método de la abundancia natural

ABSTRACT In semi-arid regions of Argentina, Adesmia bicolor (Leguminosae) is being evaluated as an indefinite cycle forage species, as it is a perennial herbaceous legume with a potentially productive stoloniferous habit and high capacity to fix nitrogen. Due to the lack of information regarding the capacity it has to fix atmospheric nitrogen in its natural ecosystem, the following objectives were proposed: I) To quantify aerial biomass and nitrogen content produced by A. bicolor during its life cycle, II) To quantify aerial biomass and nitrogen content produced by selected grasses to be used as reference species: Sorghum halepense, Paspalum notatum and Cynodon dactylon during their life cycle and III) To determine if these species are appropriate to be used in the quantification of nitrogen fixed biologically by A. bicolor with the method of natural abundance. In Villa Rumipal (province of Córdoba, Argentina) samples of A. bicolor were collected together with three grass species: P. notatum, S. halepense, and C. dactylon in the vegetative, flowering and fruiting stages. The grasses selected as reference species show phenological characteristics and life cycles similar to the legume specie under study. Aerial biomass and nitrogen content were evaluated through Kjeldahl method. Although the efficiency of biological nitrogen fixation in A. bicolor is not determined in this study, it can be predicted (based on aerial biomass data and nitrogen content) that it would be reduced after flowering stage. In the species used as a reference there is a notable increase in biomass throughout its life cycles. After the data collected was analyzed, it can be concludes that the most appropriate reference species to evaluate the nitrogen content is P. notatum, since it explores a volume of soil similar to A. bicolor. S. halepense and C. dactylon had a higher nitrogen content, this can be attributed to the fact that their underground systems are more vigorous and, therefore, are more able to extract nitrogen from the soil.RESUMEN En regiones semiáridas de Argentina se está evaluando Adesmia bicolor (Leguminosae) como especie forrajera de ciclo indefinido, ya que es una leguminosa herbácea perenne de hábito rastrero y con elevada capacidad para fijar nitrógeno. Debido a la falta de información respecto a la capacidad que posee para fijar nitrógeno atmosférico en su ecosistema natural, se propuso como objetivos de trabajo: I) Cuantificar la biomasa aérea y el contenido de nitrógeno producidos por A. bicolor durante su ciclo de vida, II) Cuantificar la biomasa aérea y el contenido de nitrógeno producidos por las gramíneas seleccionadas para utilizar como especies de referencia: Sorghum halepense, Paspalum notatum y Cynodon dactylon durante su ciclo de vida y III) Determinar si estas especies son apropiadas para ser utilizadas en la cuantificación del nitrógeno fijado biológicamente por A. bicolor con el método de la abundancia natural. En Villa Rumipal (provincia de Córdoba, Argentina) se recolectaron muestras de A. bicolor junto con tres especies gramíneas: P. notatum, S. halepense y C. dactylon en las etapas vegetativa, floración y fructificación. Las gramíneas seleccionadas como referencia presentan características fenológicas y ciclos de vida similares a la especie leguminosa en estudio. Se evaluó biomasa aérea y contenido de nitrógeno a través del método de Kjeldahl. Si bien en este estudio no se determina la eficiencia de la fijación biológica de nitrógeno en A. bicolor, se puede predecir (a partir de los datos de biomasa aérea y contenido de nitrógeno) que esta se vería disminuida después de la floración. En las especies utilizadas como referencia se observa un notable incremento de biomasa a lo largo de su ciclo de vida. Luego de analizar los datos obtenidos, se puede concluir que la especie de referencia más apropiada para evaluar el contenido de nitrógeno es P. notatum, ya que explora un volumen de suelo similar a A. bicolor. S, halepense y C. dactylon presentaron un contenido de nitrógeno mayor que la leguminosa estudiada, lo que puede atribuirse a que sus sistemas subterráneos son más vigorosos y, por lo tanto, presentan mayor capacidad para extraer nitrógeno del suelo

Growth rate, biomass production and dynamics of carbohydrate mobilization in cultivated Adesmia bicolor (Poir.) DC (Fabaceae)

Las leguminosas perennes nativas son importantes en los pastizales de diversas partes del mundo y pueden contribuir a mejorar el valor nutritivo de los sistemas de pastoreo naturales y cultivados. En la región árida y semiárida central de Argentina se ha comenzado la domesticación de especies con potencial forrajero, entre ellas Adesmia bicolor (Poir.) DC. El objetivo de este trabajo es evaluar y relacionar el ritmo de crecimiento de la especie con la producción de biomasa y la dinámica de movilización de carbohidratos durante un ciclo de cultivo. Para el estudio del ritmo de crecimiento se seleccionaron plántulas y plantas adultas, en las que se registraron variables vegetativas y reproductivas. Cada 60 días se registró la biomasa aérea y subterránea en un área de 0,25 m2 y la concentración de carbohidratos en órganos subterráneos. La baja relación tallo/raíz de la plántula y el crecimiento clonal de la planta adulta de A. bicolor favorecen el establecimiento y desarrollo del cultivo con un máximo crecimiento vegetativo en invierno-primavera, el cual está determinado por la ramificación de los ejes cotiledonares y profilares y el aumento de la longitud de sus entrenudos. El ciclo de vida indefinido garantiza una tasa fotosintética importante que permite no sólo el mantenimiento del cultivo, sino también suficiente concentración de carbohidratos en raíces y estolones para permitir su rápida recuperación durante el rebrote. Estos resultados indican que A. bicolor es una especie que presenta atributos deseables para la producción forrajera.Native perennial legumes are an important component of rangelands in many parts of the world and may contribute to improve the nutritional value of natural and cultivated grazing systems. In the arid and semi-arid central region of Argentina, the domestication of species with forage potential, such as Adesmia bicolor (Poir.) DC, has begun. The objective of this work was to evaluate a crop of Adesmia bicolor (Poir.) DC and relate crop growth to biomass production, and carbohydrate mobilization dynamics during one year. To evaluate growth dynamics, seedlings and adult plants were selected, and vegetative and reproductive variables were recorded every 7 to 10 days. In addition, aerial and ground biomass samples were taken in an area of 0,0625 m2 every 60 days and processed to determine carbohydrate mobilization dynamics. The low stem:root ratio observed in the seedlings and the clonal growth of A. bicolor adults plants favor the establishment and development of the crop, reaching its maximum vegetative growth in winter/spring. This maximum growth is determined by high cotyledonary and prophyllar branching with increased internode length. The indefinite life cycle guarantees an important photosynthetic rate that allows for not only crop persistence, but also enough carbohydrate concentration in roots and stolons, which permits a rapid recovery during regrowth. These results indicate that A. bicolor is a species that has desirable attributes for forage production.Fil: Perez, Veronica Celeste. Universidad Nacional de Río Cuarto.

Considerations and consequences of allowing DNA sequence data as types of fungal taxa

Nomenclatural type definitions are one of the most important concepts in biological nomenclature. Being physical objects that can be re-studied by other researchers, types permanently link taxonomy (an artificial agreement to classify biological diversity) with nomenclature (an artificial agreement to name biological diversity). Two proposals to amend the International Code of Nomenclature for algae, fungi, and plants (ICN), allowing DNA sequences alone (of any region and extent) to serve as types of taxon names for voucherless fungi (mainly putative taxa from environmental DNA sequences), have been submitted to be voted on at the 11th International Mycological Congress (Puerto Rico, July 2018). We consider various genetic processes affecting the distribution of alleles among taxa and find that alleles may not consistently and uniquely represent the species within which they are contained. Should the proposals be accepted, the meaning of nomenclatural types would change in a fundamental way from physical objects as sources of data to the data themselves. Such changes are conducive to irreproducible science, the potential typification on artefactual data, and massive creation of names with low information content, ultimately causing nomenclatural instability and unnecessary work for future researchers that would stall future explorations of fungal diversity. We conclude that the acceptance of DNA sequences alone as types of names of taxa, under the terms used in the current proposals, is unnecessary and would not solve the problem of naming putative taxa known only from DNA sequences in a scientifically defensible way. As an alternative, we highlight the use of formulas for naming putative taxa (candidate taxa) that do not require any modification of the ICN.Peer reviewe

Phylogenomics, divergence times and notes of orders in Basidiomycota

Basidiomycota is one of the major phyla in the fungal tree of life. The outline of Basidiomycota provides essential taxonomic information for researchers and workers in mycology. In this study, we present a time-framed phylogenomic tree with 487 species of Basidiomycota from 127 families, 47 orders, 14 classes and four subphyla; we update the outline of Basidiomycota based on the phylogenomic relationships and the taxonomic studies since 2019; and we provide notes for each order and discuss the history, defining characteristics, evolution, justification of orders, problems, significance, and plates. Our phylogenomic analysis suggests that the subphyla diverged in a time range of 443-490 Myr (million years), classes in a time range of 312-412 Myr, and orders in a time range of 102-361 Myr. Families diverged in a time range of 50-289 Myr, 76-224 Myr, and 62-156 Myr in Agaricomycotina, Pucciniomycotina, and Ustilaginomycotina, respectively. Based on the phylogenomic relationships and divergence times, we propose a new suborder Mycenineae in Agaricales to accommodate Mycenaceae. In the current outline of Basidiomycota, there are four subphyla, 20 classes, 77 orders, 297 families, and 2134 genera accepted. When building a robust taxonomy of Basidiomycota in the genomic era, the generation of molecular phylogenetic data has become relatively easier. Finding phenotypical characters, especially those that can be applied for identification and classification, however, has become increasingly challenging

Cardiopulmonary resuscitation in adults over 80 : outcome and the perception of appropriateness by clinicians

OBJECTIVES: To determine the prevalence of clinician perception of inappropriate cardiopulmonary resuscitation (CPR) regarding the last out‐of‐hospital cardiac arrest (OHCA) encountered in an adult 80 years or older and its relationship to patient outcome. DESIGN: Subanalysis of an international multicenter cross‐sectional survey (REAPPROPRIATE). SETTING: Out‐of‐hospital CPR attempts registered in Europe, Israel, Japan, and the United States in adults 80 years or older. PARTICIPANTS: A total of 611 clinicians of whom 176 (28.8%) were doctors, 123 (20.1%) were nurses, and 312 (51.1%) were emergency medical technicians/paramedics. RESULTS AND MEASUREMENTS: The last CPR attempt among patients 80 years or older was perceived as appropriate by 320 (52.4%) of the clinicians; 178 (29.1%) were uncertain about the appropriateness, and 113 (18.5%) perceived the CPR attempt as inappropriate. The survival to hospital discharge for the “appropriate” subgroup was 8 of 265 (3.0%), 1 of 164 (.6%) in the “uncertain” subgroup, and 2 of 107 (1.9%) in the “inappropriate” subgroup (P = .23); 503 of 564 (89.2%) CPR attempts involved non‐shockable rhythms. CPR attempts in nursing homes accounted for 124 of 590 (21.0%) of the patients and were perceived as appropriate by 44 (35.5%) of the clinicians; 45 (36.3%) were uncertain about the appropriateness; and 35 (28.2%) perceived the CPR attempt as inappropriate. The survival to hospital discharge for the nursing home patients was 0 of 107 (0%); 104 of 111 (93.7%) CPR attempts involved non‐shockable rhythms. Overall, 36 of 543 (6.6%) CPR attempts were undertaken despite a known written do not attempt resuscitation decision; 14 of 36 (38.9%) clinicians considered this appropriate, 9 of 36 (25.0%) were uncertain about its appropriateness, and 13 of 36 (36.1%) considered this inappropriate. CONCLUSION: Our findings show that despite generally poor outcomes for older patients undergoing CPR, many emergency clinicians do not consider these attempts at resuscitation to be inappropriate. A professional and societal debate is urgently needed to ensure that first we do not harm older patients by futile CPR attempts. J Am Geriatr Soc 68:39–45, 201
