Cottonseed is a rich source of high quality protein, but its value as an animal feed is limited by gossypol, a toxic polyphenolic compound contained in glands located throughout the plant. This compound helps protect the plant from pests. Totally glandless varieties have been developed, but not adopted as these plants are left vulnerable to pests. This study describes a breeding strategy to dec...
Cotton (Gossypium hirsutum L.) seed develops single-celled long fibres (lint) from the seed-coat epidermis at anthesis. Previous studies have shown that the initiation and rapid elongation of these fibres requires the expression of sucrose synthase (Sus) and, potentially, a transient closure of plasmodesmata. This study extends the previous work to examine the patterns of Sus expression and pla...
HERE are now several cases reported in the literature in which the transfer a chromosomal segment from one species of Gossypium to another results in altered recombination frequency in the chromosome to which the “foreign” segment has been transferred (SILOW 1944; RHYNE 1958; PHILLIPS 1961; STEPHENS 1961). Further, it is known that the altered recombination may take the form of either increased...
In this study, six taxa of micromycetous fungi collected from Golestan province (N Iran) during spring and summer of 2010, are reported. Melanospora zobelii on Picoa lefebvrei, Diachea leucopodia on Sambucus nigra, Choanephora cucurbitarum on Brassica oleracea, Trichurus spiralis on Prunus domestica, tuber of Solanum tuberosum and seeds of Gossypium hirsutum and Dictyosporium heptasporum on dea...
Approximately 185,000 Gossypium EST sequences comprising >94,800,000 nucleotides were amassed from 30 cDNA libraries constructed from a variety of tissues and organs under a range of conditions, including drought stress and pathogen challenges. These libraries were derived from allopolyploid cotton (Gossypium hirsutum; A(T) and D(T) genomes) as well as its two diploid progenitors, Gossypium arb...
HE cultivated cottons are divided into two groups: the diploid Asiatic species Gossypium arboreum and G. herbaceum and the New World amphidiploids G. hirsutum and G. barbadense. The taxa within each of these groups are readily crossed, and the F, in each case is vigorous and fertile. F, and subsequent generations, however, contain either depauperate types or plants that closely resemble one of ...
MicroRNAs (miRNAs) are a class of non-coding RNAs that regulate gene post-transcriptional expression in animals and plants. Comparatively genomic computational methods have been developed to predict new miRNAs in worms, humans, and Arabidopsis. Here we present an EST (Expressed Sequence Tags)--and GSS (Genomic Survey Sequences)-based combined approach for the detection of novel miRNAs in Gossyp...
In the framework of a gene flow assessment, we investigated the natural hybridization rate between Gossypium hirsutum (AADD genome) and G. herbaceum (AA genome). The latter species, a diploid progenitor of G. hirsutum, is spontaneously present in South Africa. Reciprocal crosses were performed without emasculation between G. herbaceum and G. hirsutum Neither examination of the morphological cha...
This study was conducted for investigating the impact of irrigation interval and deficit on seed cotton yield, fiber quality, water productivity (Gossypium hirsutum L.) in Şanlıurfa province Türkiye during years 2020 2021. The experiment using a randomized complete block design with split plots. main plots included three intervals (D1: 4 day, D2: 8 D3: 12 day), while sub-plots consisted levels ...
Polyamines have been associated with a large number of plant growth and developmental processes. In particular, they have been associated with floral initiation with increased polyamines concentration occurring during flowering in horticulture plants. However, there is limited information about polyamines in cotton (Gossypium hirsutum L.) and how they are distributed in the cotton plant. In add...
