Abstract Background GASA (Giberellic Acid Stimulated in Arabidopsis ) gene family plays a crucial role the phytohormone signaling pathway, growth and development, stress responses plants. Many homologs have been identified various Nevertheless, little is known about these proteins cotton. Results In current study, we 19, 17, 25, 33, 38 genes via genome-wide analyses of Gossypium herbaceum , G. ...

Root-knot nematode (RKN) resistance introgression into tetraploid cotton (Gossypium spp.) and its ancestral genome origin were examined. Resistance sources (‘Acala NemX’, ‘Clevewilt 6’, Auburn 623 RNR) were compared with diverse germplasm using simple sequence repeat (SSR) markers from chromosomes 7, 11, and 14 and DNA sequence information. Differences (P < 0.05) were observed for mean root gal...

A detailed restriction fragment length polymorphism map was used to determine the chromosomal locations and subgenomic distributions of quantitative trait loci (QTLs) segregating in a cross between cultivars of allotetraploid (AADD) Gossypium hirsutum (‘‘Upland’’ cotton) and Gossypium barbadense (‘‘Sea Island,’’ ‘‘Pima,’’ or ‘‘Egyptian’’ cotton) that differ markedly in the quality and quantity ...
