Evaluation of the combining ability of CMS lines in crosses with samples of grain sorghum and Sudan grass

Received: April 2nd, 2021 ; Accepted: July 28th, 2021 ; Published: August 3rd, 2021 ; Correspondence: [email protected] versatility of use, species diversity, and high drought resistance have ensured the demand for sorghum among agricultural crops in the world. Currently, the most promising direction of breeding is the creation of F1 sorghum hybrids, which is based on the identification and selection of parental forms with high combining ability. In this paper, the combining ability analysis crosses of two hybridization schemes: grain×grain sorghum and grain sorghum×Sudan grass was carried out using topcross method. Gene action governing inheritance of a particular trait can be measured in terms of general and specific combining ability estimates, where general combining ability effects are mostly indicative of additive gene action (ms (GCA)/ms (SCA)>1)and specific combining ability effects - non-additive (ms (GCA)/ms (SCA)<1). Genes with an additive effect participate in the genetic control of breeding-valuable traits, which is proven byms(GCA)/ms (SCA) ratios changing within1.10-28.01 range. It is advisable to involve CMS-lines A3 Feterita 14, A2 KVV 114 and A2 O-1237 to create high-yielding hybrids of grain sorghum; highly productive sorghum-sudangrasshybridss - lines L-106, L-143 and Anastasiya, Kinelskaya 100, Elegiya variety samples; with a high share of grain in the total biomass – Allegoriya, Krasnodarskaya 75 and Zonalskaya 6 variety samples. CMS lines are distinguished by high and average CA values both in crosses with samples of grain sorghum and Sudan grass: by weight of 1,000 grains - A2 O-1237; by seed yield and weight of 1,000 grains - A2 KVV 114

The role of chemokine genes in the formation of terminal stage of chronic renal failure

The data on the role of chemokine genes (+1931A/T CCL4, A/G CXCL11 (rs4512021), -403A/G CCL5, C/G CCL2 (rs2857657), -801G/A CXCL12) in the formation of terminal stage of chronic renal failure, in patients with chronic glomerulonephritis, is presented in the work. It was established, that the allele A CXCL11 (rs4512021) (OR = 1.65) was the marker for the development of terminal stage of chronic renal insufficiency, and the genotype GG CXCL11was a protective factor for the development of terminal stage of chronic renal failure (OR = 0.22

Study of Biological Properties of Effective Pesticides Destructor Pseudomonas Putida P2

A promising approach for remediation of contaminated soils is the use of biological products based on microorganisms-destructors. Of particular interest are the strains that can decompose several types of pollutants. Potential strains-destructors should be not only effective but also adapted for certain soil and climatic conditions. In addition, when introducing a significant amount of biological agents into the ecosystem, the lack of toxicological and pathogenic effects on plants, animals, and humans is particularly important. The object of the study is the destructor strain of sim-triazine herbicide of prometrin Pseudomonas putida P2. The study explores the ability of strain to use various pesticides as the only carbon source, the effect of bacterial culture on seed germination, biotesting of strain on toxicity using earthworms. Besides, the study presents the phytopathogenic factors and enzymes causing bacteria invasiveness into animals and humans. The determination of dehydrogenase activity of prometrin destructor strain shows that this strain can also use active ingredients of pesticide malathion, HCH, and 4,4-DDT as only sole carbon source. It is also established that the studied strain Pseudomonas putida P2 increases the germination of seeds of the variety Saratovskaya 70 and carrots of the variety Samson and does not possess pathogenicity factors. The strain biotesting on the earthworms revealed no acute toxicity of the culture. The analysis of data obtained from the model pollution shows that the introduction of the destructor of Prometrium Pseudomonas putida P2 into the soil can create favorable conditions for vital activity and reproduction of earthworms

A comparative study of optical properties and X-ray induced luminescence of octahedral molybdenum and tungsten cluster complexes

© 2017 The Royal Society of Chemistry. Octahedral metal cluster complexes have high potential for biomedical applications. In order to evaluate the benefits of these moieties for combined CT/X-ray luminescence computed tomography, this paper compares photoluminescence, radiodensity and X-ray induced luminescence properties of eight related octahedral molybdenum and tungsten cluster complexes [{M 6 I 8 }L 6 ] n (where M is Mo or W and L is I - , NO 3 - , OTs - or OH - /H 2 O). This article demonstrates that despite the fact that molybdenum cluster complexes are better photoluminescence emitters, tungsten cluster complexes, in particular (Bu 4 N) 2 [{W 6 I 8 }I 6 ], demonstrate significantly higher X-ray induced luminescence due to a combination of relatively good photoluminescence properties and high X-ray attenuation. Additionally, photo-degradation of [{M 6 I 8 }(NO 3 ) 6 ] 2- was evaluated

Luminescent coordination polymers based on Ca²⁺ and octahedral cluster anions [{M₆Clⁱ₈}Clᵃ₆}²⁻ (M = Mo, W) : synthesis and thermal stability studies

Luminescent coordination polymers (CPs) based of inexpensive stable precursors are attractive materials for applications. Here we report the synthesis and evaluation of the stability and photophysical characteristics of the first examples of phosphorescent CPs based on octahedral molybdenum and tungsten cluster anions. Specifically 1D CP trans-[{Ca(OPPh₃)₄}{{M₆Clⁱ₈}Clᵃ₆}]∞ (M = Mo, W) can be obtained either directly at increased temperature or via intermediate phases [cis-Ca(OPPh₃)₄(H₂O)₂][{M₆Clⁱ₈}Clᵃ₆]∙2CH₃CN that are stable at room-temperature, but convert to the titled CP at temperatures above 100 °C
