Genome-wide analysis of RWP-RK transcription factor family reveals its roles in nitrogen response in rice (<i>Oryza sativa</i>).

ABSTRACT:

Introduction

The RWP-RK transcription factor family plays a pivotal role in nitrogen response and gametophyte development. Despite its biological importance, the evolutionary relationships and functional characteristics of RWP-RK genes in rice remain incompletely understood. This study aimed to investigate the structure, classification, expression patterns, and potential regulatory roles of RWP-RK transcription factors in rice (Oryza sativa), with a focus on their involvement in nitrogen signaling and reproductive development.

Methods

A comprehensive genome-wide analysis was conducted to identify RWP-RK genes in rice. A total of 13 genes encoding 14 proteins, including two alternative splicing variants of OsNLP5, were identified and mapped across 8 of the 12 rice chromosomes
