摘要: 促有丝分裂原活化蛋白激酶(MAPK)在植物生长发育及抗逆胁迫过程中发挥重要作用。为了解花生中MAPK基因的情况,利用RNA测序技术对花生耐盐突变体(S2)和对照(S4)进行了转录组分析,筛选出了14个MAPK基因,位于花生野生种基因组A组的6条染色体上。聚类分析表明,花生14个MAPK基因中13个可以聚到已报道的4个亚类中。利用花生S2和S4构建了盐胁迫处理前后的表达谱,根据调整后的P值,筛选出6个MAPK基因在S2和(或)S4受盐胁迫诱导表达,分别属于A(1个)和D亚类(5个)。为花生MAPK基因的功能验证和利用奠定了基础。

Abstract: Mitogen activated protein kinase (MAPK) plays an important role in plant growth and development,and stress resistance in plant.In order to improve our understanding of the MAPK genes in peanut,RNA-seq was used to analyze one transcriptomic library constructed using a mutant with higher salinity resistance (S2) and its control (S4) in this study,14 MAPK genes were screened and located on six chromosomes of A genome from wild species.Clustering analysis showed that 13 out of 14 MAPK genes were assorted to four subgroups reported previously.Digital gene expression profiles were constructed using S2 and S4 samples before and after salinity treatment,according to the adjusted P value,six MAPK genes were found to be responsive to salinity treatment in S2 and (or) S4,which belonged to A (1)and D (5) subgroups,respectively.This study can provide the basis for functional identification and application of MAPK genes in peanut.

Key words: Peanut, MAPK gene, Salinity stress, RNA-seq
