Abstract
Salinity stress is one of the most detrimental causes of productivity loss and death among plants including crops. Worldwide, rice is the most common staple food and also, most commonly under stressed crop. Plant protein with single PLAT (Polycystin-1, Lipoxygenase, Alpha-toxin and Triacylglycerol lipase) domain and PLAT plant stress protein family are found in most angiosperms. The exact mechanism of PLAT plant protein isn’t assuredly understood yet available reports suggest, overexpressed PLAT1 protein enhances abiotic stress, especially temperature and salt tolerance along with heavy metal stress tolerance in plants. In Arabidopsis and tobacco plant, PLAT1 appeared to be a positive mediator for growth under non-stressed condition, ABA signalling and ER stress tolerance. PLAT1 is also present in Oryza sativa both in indica and japonica group. Most of the proteins were predicted, hence lacking proper PDB structure. So, this study intended to find the possible structural resemblance between PLAT1 both in Oryza and Arabidopsis. Possibly to understand the nature of mechanism by building homology models by using SWISSMODEL and comparing sequences by MSA. Thus, encouraging further scientific use and proteomic study in order to improve salinity stress tolerance and crop yielding.
