NaCl和Na2CO3胁迫下的高粱MAPKs基因家族表达模式
Expression Pattern of MAPKs Genes in Sorghum bicolor under Stresses of NaCl and Na2CO3
摘要
Abstract
The availability of sorghum genome makes it possible to perform the genome-wide analysis of the expression profile of MAPKs genes in Sorghum bicolor under the stresses of NaCl and Na2CO3 so as to explore the MAPKs involvement into saline-alkali signaling pathway. The results show that 16 MAPKs genes were dentified from the genome of Sorghum bicolor, namely SbMPKs, and their expression profiles under the stresses of NaCl and Na2CO3 differ from each other significantly. This suggests that neutral salt-induced signal response may differ from that induced by alkaline salt. Under the stress of NaCl, all SbMPKs were up-regulated continuously during 24 h except the SbMPKl3 whose expression reached to the maximum at 12 h.Under the stress of Na2CO3, however, only SbMPK3,SbMPKlO and SbMPKl3 were up-regulated, implyingthat SbMPKs axe likely responsible specifically for alkaline salt stress in sorghum. Phylogenetic analysisclassified SbMPKl3 into the C group of MAPKs, which is similar to OsMAPKl that is responsible to ABA andsalt stress in rice, further confirming that it is involved possibly in the regulation of salt stress response genesin sorghum.关键词
