Analysis of maize PAL pan gene family and expression pattern under lepidopteran insect stress.

ABSTRACT:

Introduction

Phenylalanine ammonia-lyase (PAL), as the rate-limiting enzyme in plant phenylpropanoid metabolism, catalyzes the conversion of L-phenylalanine to trans-cinnamic acid and plays a pivotal role in plant-insect resistance mechanisms.

Methods

Utilizing a maize pangenome constructed from 26 high-quality genomes, we systematically identified the ZmPAL gene family members. Evolutionary pressure and structural variation (SV) analyses were conducted, alongside reanalysis of publicly available RNA-seq datasets under lepidopteran stress conditions. Temporal expression patterns were further validated via qRT-PCR.

Results

This investigation identified 29 ZmPAL genes, comprising 7 core, 2 near-core, 12 dispensable, and 8 private genes, revealing substanti
