主 题:Potato phosphate transporter gene short-term phosphate-deficiency stress biological analysis
摘 要:Inorganic phosphate(Pi)is one of the main nutrients necessary for plant *** transporters mediate the acquisition,transport and recycling of phosphate,which is essential for plant growth and *** PHT1 has been reported in many plants at home and abroad,it is rarely studied in ***,it is of great significance to study the PHT1 family members in order to understand the molecular response mechanism of potato in low phosphate *** this study,a total of 6 potato PHT1 genes were identified and *** was found that after the expression of different members of potato PHT1 gene,there were certain differences in amino acids and proteins,and the transmembrane domains ranged from 6 to *** difference in the secondary and tertiary protein structure of potato PHT1 also led to a difference in protein *** addition,the expression of the PHT1 gene in potato increased obviously during 3~9 h of Pi deficiency ***,the expression levels of different genes in roots,stems and leaves are distinctly different,but the expression levels of the StPHT1;6 and StPHT1;10 genes are very high in roots,stems and leaves,indicating that these two genes may participate in the absorption of Pi in potato and play a role in Pi *** two genes play a major role in the regulation of expression under short-term Pi deficiency *** results provide an important reference for further understanding the evolution and function of potato phosphate transporters,and have important significance for improving the ability of potato to tolerate low Pi.
