Karakterisasi Tanaman Tamarillo Di Sulawesi Selatan

Tamarillo (Chypomandra betacea Sent.) is a high land plant, that has been grown and developed in several regions in Indonesia, including in Toraja. However, the fruit that has a slightly sour sweet taste has not been widely used as nutritious food. The study aimed to characterize tamarillo plants that grow in the three developing areas. Data and information obtained from this activity can be used as an important information to determine the characters and to distinguish cultivars tamarillo plants in the area. The research was conducted using survey methods and direct observation in the field from March-September 2014 in three areas, namely Sapan and Kantun Poya District, North Toraja Regency, and Sangalla District, in Tana Toraja Regency, South Sulawesi Province. Data were collected for morphological characters of stems, leaves, flowers, fruits, and fruit nutrient content. Data were analyzed by simple statistical analysis and genetic relationship analysis using NTSys Program 2.1. The results showed that the toraja tamarillo had erect stems, round shape, height 2–5 meters, the leaves were dark green, flat type, slippery surface, facing upward. Purple flowers, the number of 10–12 fruits per cluster, with five stamens. Fruit type flat, oval, raw green color and when ripe striped maroon, production of 10–15 kg fruit/tree/year. The content of vitamin C was 30 mg/100 g, 2.6% of sugar, 85% of fruit juice content, 1.4% of total acid content, the amount of dissolved solids in the juice was 12.35%. The result of genetic relationship analysis using a 45 character traits showed that the cultivars Sangalla and Kantun Poya, as well as Sapan and Sangalla cultivars had a closed genetic relationship.

RNA-Seq and molecular docking reveal multi-level pesticide resistance in the bed bug

<p>Abstract</p> <p>Background</p> <p>Bed bugs (<it>Cimex lectularius</it>) are hematophagous nocturnal parasites of humans that have attained high impact status due to their worldwide resurgence. The sudden and rampant resurgence of <it>C. lectularius </it>has been attributed to numerous factors including frequent international travel, narrower pest management practices, and insecticide resistance.</p> <p>Results</p> <p>We performed a next-generation RNA sequencing (RNA-<it>Seq</it>) experiment to find differentially expressed genes between pesticide-resistant (PR) and pesticide-susceptible (PS) strains of <it>C. lectularius</it>. A reference transcriptome database of 51,492 expressed sequence tags (ESTs) was created by combining the databases derived from <it>de novo </it>assembled mRNA-<it>Seq </it>tags (30,404 ESTs) and our previous 454 pyrosequenced database (21,088 ESTs). The two-way GLMseq analysis revealed ~15,000 highly significant differentially expressed ESTs between the PR and PS strains. Among the top 5,000 differentially expressed ESTs, 109 putative defense genes (cuticular proteins, cytochrome P450s, antioxidant genes, ABC transporters, glutathione <it>S</it>-transferases, carboxylesterases and acetyl cholinesterase) involved in penetration resistance and metabolic resistance were identified. Tissue and development-specific expression of P450 CYP3 clan members showed high mRNA levels in the cuticle, Malpighian tubules, and midgut; and in early instar nymphs, respectively. Lastly, molecular modeling and docking of a candidate cytochrome P450 (CYP397A1V2) revealed the flexibility of the deduced protein to metabolize a broad range of insecticide substrates including DDT, deltamethrin, permethrin, and imidacloprid.</p> <p>Conclusions</p> <p>We developed significant molecular resources for <it>C. lectularius </it>putatively involved in metabolic resistance as well as those participating in other modes of insecticide resistance. RNA-<it>Seq </it>profiles of PR strains combined with tissue-specific profiles and molecular docking revealed multi-level insecticide resistance in <it>C. lectularius</it>. Future research that is targeted towards RNA interference (RNAi) on the identified metabolic targets such as cytochrome P450s and cuticular proteins could lay the foundation for a better understanding of the genetic basis of insecticide resistance in <it>C. lectularius</it>.</p

Light whole genome sequence for SNP discovery across domestic cat breeds

<p>Abstract</p> <p>Background</p> <p>The domestic cat has offered enormous genomic potential in the veterinary description of over 250 hereditary disease models as well as the occurrence of several deadly feline viruses (feline leukemia virus -- FeLV, feline coronavirus -- FECV, feline immunodeficiency virus - FIV) that are homologues to human scourges (cancer, SARS, and AIDS respectively). However, to realize this bio-medical potential, a high density single nucleotide polymorphism (SNP) map is required in order to accomplish disease and phenotype association discovery.</p> <p>Description</p> <p>To remedy this, we generated 3,178,297 paired fosmid-end Sanger sequence reads from seven cats, and combined these data with the publicly available 2X cat whole genome sequence. All sequence reads were assembled together to form a 3X whole genome assembly allowing the discovery of over three million SNPs. To reduce potential false positive SNPs due to the low coverage assembly, a low upper-limit was placed on sequence coverage and a high lower-limit on the quality of the discrepant bases at a potential variant site. In all domestic cats of different breeds: female Abyssinian, female American shorthair, male Cornish Rex, female European Burmese, female Persian, female Siamese, a male Ragdoll and a female African wildcat were sequenced lightly. We report a total of 964 k common SNPs suitable for a domestic cat SNP genotyping array and an additional 900 k SNPs detected between African wildcat and domestic cats breeds. An empirical sampling of 94 discovered SNPs were tested in the sequenced cats resulting in a SNP validation rate of 99%.</p> <p>Conclusions</p> <p>These data provide a large collection of mapped feline SNPs across the cat genome that will allow for the development of SNP genotyping platforms for mapping feline diseases.</p

Inguinal hernia surgery in the Netherlands: are patients treated according to the guidelines?

Purpose In 2003, a dedicated Dutch committee developed vidence-based guidelines for the treatment of nguinal hernia (IH) in children and adults. The aim of this tudy was to describe trends in hernia care before and after he publication of the guidelines on IH surgery in the etherlands. ethods Originally, a retrospective baseline analysis of H surgery in 90 Dutch hospitals was performed among atients treated for IH in 2001. The results of this baseline nalysis were compared with a recently performed second nalysis of patients treated for IH in 2005. esults In children\\4 years of age, the study showed a ignificant decrease of contralateral explorations. In adults, he study showed that significantly more patients were reated with a mesh-based repair in 2005 (95.9 vs. 78.8%, <0.01eover, there was an increase of patients ith bilateral hernia treated with an endoscopic technique 41.5 vs. 22.3%, P<0.01) and more patients were treated n day surgery (53.5 vs. 38.6%, P<0.01). Lastly, a decline n operations performed for recurrent IH in adults was bserved (10.9 vs. 13.3%, P<0.01). onclusion This study showed that most patients with IH n the Netherlands were treated according to the main ecommendations of the Dutch evidence-based guidelines

Quantitative trait loci conferring grain mineral nutrient concentrations in durum wheat 3 wild emmer wheat RIL population

Mineral nutrient malnutrition, and particularly deficiency in zinc and iron, afflicts over 3 billion people worldwide. Wild emmer wheat, Triticum turgidum ssp. dicoccoides, genepool harbors a rich allelic repertoire for mineral nutrients in the grain. The genetic and physiological basis of grain protein, micronutrients (zinc, iron, copper and manganese) and macronutrients (calcium, magnesium, potassium, phosphorus and sulfur) concentration was studied in tetraploid wheat population of 152 recombinant inbred lines (RILs), derived from a cross between durum wheat (cv. Langdon) and wild emmer (accession G18-16). Wide genetic variation was found among the RILs for all grain minerals, with considerable transgressive effect. A total of 82 QTLs were mapped for 10 minerals with LOD score range of 3.2–16.7. Most QTLs were in favor of the wild allele (50 QTLs). Fourteen pairs of QTLs for the same trait were mapped to seemingly homoeologous positions, reflecting synteny between the A and B genomes. Significant positive correlation was found between grain protein concentration (GPC), Zn, Fe and Cu, which was supported by significant overlap between the respective QTLs, suggesting common physiological and/or genetic factors controlling the concentrations of these mineral nutrients. Few genomic regions (chromosomes 2A, 5A, 6B and 7A) were found to harbor clusters of QTLs for GPC and other nutrients. These identified QTLs may facilitate the use of wild alleles for improving grain nutritional quality of elite wheat cultivars, especially in terms of protein, Zn and Fe
