The genome sequence of Sea-Island cotton (Gossypium barbadense) provides insights into the allopolyploidization and development of superior spinnable fibres. Scientific Reports. 2015 Dec 4; 5:17662
Gossypium hirsutum contributes the most production of cotton fibre, but G. barbadense is valued for its better comprehensive resistance and superior fibre properties. However, the allotetraploid genome of G. barbadense has not been comprehensively analysed. Here we present a high-quality assembly of the 2.57 gigabase genome of G. barbadense, including 80,876 protein-coding genes. The double-sized genome of the A (or At) (1.50 Gb) against D (or Dt...

Fifty years of sustained investment in research and development has left the Australian cotton industry well placed to manage nitrogen (N) fertiliser. The average production in the Australian cotton industry today is greater than two tonnes of lint per hectare due to improved plant genetics and crop management. However, this average yield is well below the yield that would be expected from the amount of N fertiliser used. It is clear from the rec... [more]
  • Dehariya P, Kataria S, Guruprasad KN, Pandey GP. Saponin synthesis and cotton growth is antagonistically regulated by solar UV-B radiation. Journal of Cotton Research. 2018 DEC 3; 1:14
Background Earlier we have reported that the exclusion of solar UV-B increased the growth and yield of cotton plants as compared with ambient UV-B. The UV-B radiation effects on the saponins and the impact of ambient and reduced UV-B on the accumulation of saponins has not been investigated yet. Thus a field experiment was conducted to study the influence of solar UV-B on the growth response and saponin synthesis in cotton (Gossypium hirsutum) va... [more]

Background Within-canopy interception of photosynthetically active radiation (PAR) impacts yield and other agronomic traits in cotton (Gossypium hirsutum L.). Field experiments were conducted to investigate the influence of 6 cotton varieties (they belong to 3 different plant types) on yield, yield distribution, light interception (LI), LI distribution and the relationship between yield formation and LI in Anyang, Henan, in 2014 and 2015. Result... [more]
  • Zhang B, Zhang X, Guo L, Qi T, Wang H, Tang H, Qiao X, Shahzad K, Xing C, Wu J. Genome-wide analysis of Rf-PPR-like (RFL) genes and a new InDel marker development for Rf1 gene in cytoplasmic male sterile CMS-D2 Upland cotton. Journal of Cotton Research. 2018 OCT 29;1:12
Background Cytoplasmic male sterility in flowering plants is a convenient way to use heterosis via hybrid breeding and may be restored by nuclear restorer-of-fertility (Rf) genes. In most cases, Rf genes encoded pentatricopeptide repeat (PPR) proteins and several Rf genes are present in clusters of similar Rf-PPR-like (RFL) genes. However, the Rf genes in cotton were not fully characterized until now. Results In total, 35 RFL genes were identifi... [more]
  • Jia Y, Pan Z, He S, Gong W, Geng X, Pang B, Wang L, Du X. Genetic diversity and population structure of Gossypium arboreum L. collected in China. Journal of Cotton Research. 2018 SEP 28;1:11
Background Gossypium arboreum is a diploid species cultivated in the Old World. It possesses favorable characters that are valuable for developing superior cotton cultivars. Method A set of 197 Gossypium arboreum accessions were genotyped using 80 genome-wide SSR markers to establish patterns of the genetic diversity and population structure. These accessions were collected from three major G. arboreum growing areas in China. A total of 255 alle... [more]
  • Zhang Y, Wang Q, Zuo D, Cheng H, Liu K, Ashraf J, Li S, Feng X, Yu JZ, Song G. Map-based cloning of a recessive gene v1 for virescent leaf expression in cotton (Gossypium spp.). Journal of Cotton Research. 2018 AUG 31;1:10
Background Virescence, as a recognizable phenotype in the early development stage of cotton, is not only available for research on chloroplast development and photosynthesis but also for heterosis exploitation in cotton. Methods In current study, for fine mapping of virescent-1 (v1) in cotton, three populations with a total of 5 678 individuals were constructed using T582 which has the virescent trait. Tobacco rattle virus, TRV1 and TRV2 (pYL156... [more]
  • Sun R, Tian R, Ma D, Wang S, Liu C. Comparative transcriptome study provides insights into acquisition of embryogenic ability in upland cotton during somatic embryogenesis. Journal of Cotton Research. 2018 AUG 31;1:9
Background The conversion from non-embryogenic callus (NEC) to embryogenic callus (EC) is the key bottleneck step in regeneration of upland cotton (Gossypium hirsutum), and hinders the transgenic breeding of upland cotton. To investigate molecular mechanisms underlying acquisition of embryogenic potential during this process, comparation analysis of transcriptome dynamics between two upland cotton cultivars with different somatic embryogenesis ab...

  • Hussain A, Farooq J, Ahmad S, Mahmood A, Sadiq MA, Zafar UZ, Athar H. Hypoxia tolerance studies for yield, fiber and physiological traits in cotton (Gossypium hirsutum L.). Journal of Cotton Research. 2018 AUG 28;1:8
Background Hypoxia tolerance studies in cotton are very rare in Pakistan. Unpredicted and excessive rainfalls result in severe losses to cotton crop in many regions of the country due to lack of hypoxia tolerance in current cotton varieties. The genotypes that can tolerate flooding are not reported earlier. The studies were conducted to explore hypoxia tolerance in local germplasm which will help to develop hypoxia tolerant cotton varieties. Met... [more]
