    Abstract:

    Previous studies showed that Arabidopsis NHL (NDR1/HIN1-like) genes played roles in the disease resistance. By bioinformatics analysis, we identified 100 and 118 NHL genes from Sea Island cotton and upland cotton, respectively. The NHL family members from Sea Island cotton and upland cotton were found to be distributed almostly on all chromosomes. These genes can be divided into three subgroups, and all contained three conserved domains as observed with the conserved motifs of Arabidopsis NHL gene family. The expression patterns of NHL family members in upland cotton were analyzed on the basis of the previously published transcriptional data of the resistant upland cotton after inoculated with V. dahliae. Fifty-seven NHL genes represented obvious expression changes in the root and stem, with three types of and their expression patterns: (1) highly expressed before inoculation and then decreased after inoculation; (2) highly expressed before inoculation, but firstly decreased and then increased after inoculation; (3) lowly expressed before inoculation and then increased after inoculation. The genes (type-1) were negatively regulated in the cotton resistance to Verticillium wilt, while the genes (type-2 and type-3) were positively regulated. Thus, the accumulative results provided a theoretical basis for further analyzing the role of NHL gene family in cotton Verticillium wilt resistance.
