Genome-wide identification and expression analysis of <i>NPR1-</i>like genes in pearl millet under diverse biotic and abiotic stresses and phytohormone treatments.

ABSTRACT: Nonexpressor of pathogenesis-related genes 1 (NPR1) is a master regulator of salicylic acid (SA)- facilitated plant hormone signaling and plays a crucial role in plant defense through the activation of systemic acquired resistance (SAR). Although NPR1-like genes are associated with stress responses in a variety of plant species, no thorough genome-wide investigation of these genes has been undertaken in pearl millet (Pennisetum glaucum). This study discovered seven PgNPR1-like genes on four pearl millet chromosomes (Chr1, Chr2, Chr4, and Chr6), which exhibit close affinity to NPRs from other plants and have common gene structures, conserved motifs, and domains. The promoter regions of PgNPR1-like genes have numerous cis-acting elements connected with biotic and
