Identification and Expression Analysis of Phosphatidylinositol Transfer Proteins Genes in Rice

Abstract

The family of phosphatidylinositol transfer proteins (PITPs) is able to bind specific lipids to carry out various biological functions throughout different stages of plant life. But the function of PITPs in rice plant is unclear. In this study, 30 PITPs were identified from rice genome, which showed differences in physicochemical properties, gene structure, conservation domains, and subcellular localization. The promoter region of the OsPITPs genes included at least one type of hormone response element, such as methyl jasmonate (Me JA) and salicylic acid (SA). Furthermore, the expression level of OsML-1, OsSEC14-3, OsSEC14-4, OsSEC14-15, and OsSEC14-19 genes were significantly affected by infection of rice blast fungus Magnaporthe oryzae. Based on these findings, it is possible that OsPITPs may be involved in rice innate immunity in response to M. oryzae infection through the Me JA and SA pathway.

“…Subsequent investigations revealed that the motif positions and compositions of these genes were identical, suggesting that differential gene expression may be attributed to gene mutations that occurred during gene duplication, leading to the loss of certain gene segments [ 48 ]. Furthermore, changes in the motif composition during the process of gene replication may also contribute to functional differences [ 49 ]. For instance, a comparison of the motif composition between ZoHSF01 and ZoHSF03 highlighted differences, as ZoHSF01 contained motif 2, motif 4, motif 1, and motif 3, whereas ZoHSF03 lacked motif 2 ( Figure 3 ).…”

Trends and Prospects of Genetic and Molecular Research in Plants

“…As a result, SbRPAP3 not only maintained its functions, including binding to RUVBL, Hsp90, and Hsp70, but also showed that RPAP3 performs an important function in the R2TP complex. In the third article, Pei et al [ 9 ] identified 30 PITP (phosphatidylinositol transfer protein)-related genes in the rice genome, and investigated their characteristics, including physicochemical properties, gene structure, conserved regions, and subcellular location. The promoter region of the OsPITPs gene contained at least one type of hormone response element, such as methyl jasmonate (Me JA) and salicylic acid (SA).…”
