Global identification of natural antisense transcripts in Gossypium hirsutum and Gossypium barbadense under chilling stress.

ABSTRACT: Natural antisense transcripts (NATs) in model plants have been recognized as important regulators of gene expression under abiotic stresses. However, the functional roles of NATs in crops under low temperature are still unclear. Here, we identified 815 and 689 NATs from leaves of Gossypium hirsutum and G. barbadense under chilling stress. Among those, 224 NATs were identified as interspecific homologs between the two species. The correlation coefficients for expression of NATs and their cognate sense genes (CSG) were 0.43 and 0.37 in G. hirsutum and G. barbadense, respectively. Furthermore, expression of interspecific NATs and CSGs alike was highly consistent under chilling stress with correlation coefficients of 0.90-0.91. Four cold-associated NATs were selecte
