Actin polymerizes to form part of the cytoskeleton and organize polar growth in all eukaryotic cells. Species with numerous actin genes are especially useful for dissection molecular function due redundancy neofunctionalization. Here, we investigated role a cotton (Gossypium hirsutum) gene organization filaments lobed cotyledon pavement cells highly elongated single-celled trichomes that comprise lint fibers. Using mapping-by-sequencing, virus-induced silencing, modeling, identified...
Improving cotton fiber length without reducing yield is one of the major goals breeding. However, genetic improvement by breeding has been a challenge due to narrow diversity modern cultivars and negative correlations between quality traits. A multi-parent advanced generation inter-cross (MAGIC) population developed through random mating provides an excellent resource that allows quantitative trait loci (QTL) causal genes be identified. An Upland MAGIC population, consisting 550 recombinant...
Weed management is critical to global crop production and complicated by rapidly evolving herbicide resistance in weeds. New sources of are needed for plants so that applied herbicides can be rotated or combined thwart the evolution resistant The diverse family cytochrome P450 proteins has been suggested a source detoxifying metabolism both weed plants, greater understanding these genes will offer avenues improvement novel practices. Here, we report identification CYP749A16 (Gh_D10G1401)...
The pecan nut is a nutrient-rich part of healthy diet full beneficial fatty acids and antioxidants, but can also cause allergic reactions in people suffering from food allergy to the nuts. transcriptome developing was characterized identify gene expression occurring during process development highlight those genes involved acid metabolism that commonly act as allergens. Pecan samples were collected at several time points embryo including water, gel, dough, mature stages. Library preparation...
The length of cotton fiber is an important agronomic trait that directly affects the quality yarn and fabric. Understanding molecular basis elongation would provide a means for improvement length. Ligon-lintless-1 (Li 1 ) −2 2 are monogenic dominant mutations result in extreme reduction lint on mature seeds. In near-isogenic state with wild type these two short mutants effective model system to study mechanisms elongation. Plant miRNAs regulate many aspects growth development. However,...
Next generation sequencing (RNA-seq) technology was used to evaluate the effects of Ligon lintless-2 (Li2) short fiber mutation on transcriptomes both subgenomes allotetraploid cotton (Gossypium hirsutum L.) as compared its near-isogenic wild type. Sequencing performed 4 libraries from developing fibers Li2 mutant and type lines at peak elongation followed by mapping PolyCat categorization RNA-seq data reference D5 genome (G. raimondii) for homeologous gene expression analysis. The majority...
Cockroach allergens can lead to serious allergy and asthma symptoms. Termites are evolutionarily related cockroaches, cohabitate in human dwellings, represent an increasing pest problem the United States. The Formosan subterranean termite (Coptotermes formosanus) is one of most common species southern Several assays were used determine if C. formosanus proteins cross-react with cockroach allergens. Expressed sequence tag genomic sequencing results searched for homology using BLAST 2.2.21...
Within-sample variation in cotton fiber length is a major factor influencing the production and quality of yarns. The textile industry has been searching for approaches improving long fraction minimizing short within sample to produce superior yarn quality. USTER ® High Volume Instrument (HVI) widely used rapid assessment traits from bundle. However, its effectiveness genetic studies questioned due indirect estimations that cannot be measured To overcome limits HVI traits, we utilized...
The utilization of multiple castes is a shared feature social insects. In termites, extrinsic factors have been shown to impact caste differentiation; for example, increased temperature has increase soldier production. Also, application exogenous methoprene also demonstrated objective this investigation was examine and correlate the effects variation treatments on termite differentiation, identify resulting changes in protein levels. Our results indicate that worker-to-soldier...
Most cultivated cotton (Gossypium hirsutum L.) varieties have two types of seed fibers: short fuzz fiber strongly adhered to the coat, and long lint used in textile industry. The Ligon lintless-2 (Li2) mutant has a normal vegetative phenotype but produces very on seeds. Li2 mutation is controlled by single dominant gene. We discovered large structural rearrangement at end chromosome D13 based whole-genome sequencing genetic mapping segregating populations. contains 177-kb deletion 221-kb...
The Formosan subterranean termite (Coptotermes formosanus) is an important worldwide pest, each year causing millions of dollars in structural damage and control costs. Termite colonies are composed several phenotypically distinct castes. Termites utilize these multiple castes to efficiently perform unique roles within the colony. During molting/caste differentiation process, genes believed be involved massive reorganization body plan. objective this research was analyze muscle gene, myosin,...
Formosan subterranean termites, Coptotermes formosanus, are a significant worldwide pest. Molecular gene expression is an important tool for understanding the physiology of organisms. The recent advancement molecular tools formosanus leading to termite physiology. One first steps in analyzing normalization constant reference genes. Stable genes that have across multiple treatments accurately comparing target genes' expression. objective this investigation was analyze and validate set...
SummaryPecan nuts are rich in healthy oils, proteins, carbohydrates, and essential nutrients, but can cause food allergies that rarely outgrown susceptible individuals. Three conserved seed-storage proteins from the prolamin cupin superfamilies, including 2S albumin, 7S vicillin, 11S legumin commonly identified as allergens nuts. We have characterised temporal expression of genes encoding these during nut development pecan. Transcript levels Car i 1, 4, pecan vicillin homologue (Car 7S) were...
