| fruiting branch k(+) level affects cotton fiber elongation through osmoregulation. | potassium (k) deficiency in cotton plants results in reduced fiber length. as one of the primary osmotica, k(+) contributes to an increase in cell turgor pressure during fiber elongation. therefore, it is hypothesized that fiber length is affected by k deficiency through an osmotic pathway, so in 2012 and 2013, an experiment was conducted to test this hypothesis by imposing three potassium supply regimes (0, 125, 250 kg k ha(-1)) on a low-k-sensitive cultivar, siza 3, and a low-k-tolerant cultiv ... | 2016 | 26834777 |
| comparative fiber property and transcriptome analyses reveal key genes potentially related to high fiber strength in cotton (gossypium hirsutum l.) line md52ne. | individual fiber strength is an important quality attribute that greatly influences the strength of the yarn spun from cotton fibers. fiber strength is usually measured from bundles of fibers due to the difficulty of reliably measuring strength from individual cotton fibers. however, bundle fiber strength (bfs) is not always correlated with yarn strength since it is affected by multiple fiber properties involved in fiber-to-fiber interactions within a bundle in addition to the individual fiber s ... | 2016 | 26833213 |
| small interfering rnas from bidirectional transcripts of ghmml3_a12 regulate cotton fiber development. | natural antisense transcripts (nats) are commonly observed in eukaryotic genomes, but only a limited number of such genes have been identified as being involved in gene regulation in plants. in this research, we investigated the function of small rna derived from a nat in fiber cell development. using a map-based cloning strategy for the first time in tetraploid cotton, we cloned a naked seed mutant gene (n1 ) encoding a mybmixta-like transcription factor 3 (mml3)/ghmyb25-like in chromosome a12, ... | 2016 | 26832840 |
| functional characterization of a dihydroflavanol 4-reductase from the fiber of upland cotton (gossypium hirsutum). | dihydroflavanol 4-reductase (dfr) is a key later enzyme involved in two polyphenols' (anthocyanins and proanthocyanidins (pas)) biosynthesis, however it is not characterized in cotton yet. in present reports, a dfr cdna homolog (designated as ghdfr1) was cloned from developing fibers of upland cotton. silencing ghdfr1 in cotton by virus-induced gene silencing led to significant decrease in accumulation of anthocyanins and pas. more interestingly, based on lc-ms analysis, two pa monomers, (-)-epi ... | 2016 | 26821011 |
