The functional analysis of ABCG transporters in the adaptation of pigeon pea(Cajanus cajan)to abiotic stresses
ATP-binding cassette(ABC)transporters are a class of proteins that widely present in living organisms and mediate transmembrane transport of substances by hydrolyzing ATP,play a vital role in the physiological process of growth and development in plants.The ABCG is the largest subclass of ABC transporters family,which has the most complex functions in plant's response to abiotic stress.This study focused on the effect of ABCG transporters in pigeon pea adaptation to the adverse environments(such as drought,salt,temperature,etc.).Based on this,the functional analysis of ABCG transporters in pigeon pea to abiotic stresses was conducted.In this study,a total of 51 ABCG genes(CcABCGs)were identified,further,their phylogenetic analysis and physicochemical properties of the encoded proteins,subcellular localization prediction,and conserved domains were performed.Expression analysis showed that ABCG genes have different expression profiles under tissues and abiotic stresses.Results showed that CcABCG28 was up-regulated at low temperature,however,CcABCG7 was up-regulated by drought and aluminum stress.Initial results revealed that ABCG transporters is more effective in the abiotic stresses resistance of pigeon peas,which broaden its research direction in abiotic stress resistance.
