Analysis of Peanut GLP Family Genes: Tissue-specific Expression and Induction in Response to Drought Stress
In order to study the function of the peanut GLP family genes,differential expression of eight AhGLPs between peanut testa,seed,leaf and root was analyzed under drought condition.Results showed that expression of the eight AhGLPs were higher significantly in pink testa than in others.Moreover,in peanut testa,AhGLP3 and AhGLP6 expressed highest,and followed by AhGLP1,AhGLP2 and AhGLP8.Under drought stress condition,AhGLP1 was induce-expressed only in leaves.AhGLP3,AhGLP4 and AhGLP5 were up-regulated significantly in seeds and root,and the expression of AhGLP2,AhGLP7 and AhGLP8 were induced in root,seeds and leaves by drought stress.On the contrary,AhGLP6 was down-regulated by drought stress.Under the condition of normal growth,AhGLP1,AhGLP3,AhGLP4,AhGLP5,AhGLP6 and AhGLP7 were expressed with tissue-specificity.The above results indicate that the expression of peanut GLP family genes have species-and tissue-specificity under different conditions.It could provide valuable information for the fuctional and regulatory stydies on peanut AhGLPs genes especially under drought stress.
