Quantitative Trait Locus Mapping and Candidate Gene Analysis for Wilt Resistance Using Chromosomal Segment Introgressed Line.

wilt (VW) is a soil-borne fungal disease that is caused by Kleb and seriously damages cotton production annually in China. To date, many efforts have been made to improve the resistance of upland cotton against VW, but little progress has been achieved because of a lack of resistant upland cotton to VW. is known to carry high resistance to VW; however, it is difficult to transfer the resistance trait from to upland cotton because of linkage drag and distortion in the interspecific hybrid.

Constitutive overexpression of AOS-like gene from soybean enhanced tolerance to insect attack in transgenic tobacco.

Tissue-specific and feeding-induced expression patterns of GmAOS were explored in two soybean accessions with distinct contrast in resistance grades to cotton worm: XTDD was highly susceptible and HPXQD highly resistant. GmAOS transcript levels were correlated with soybean material resistance grades. Overexpressing GmAOS in transgenic tobacco plants increased activities of allene oxide synthase, peroxidase, chymotrypsin inhabitor, and increased the trichome number.
