The PLA Gene Family in Tomato: Identification, Phylogeny, and Functional Characterization.

ABSTRACT:

Background

Phospholipase A (PLA) enzymes catalyze the hydrolysis of glycerophospholipids, releasing free fatty acids and lysophospholipids that play vital roles in plant growth, development, and stress responses.

Methods

This study identified and analyzed SlPLA genes through bioinformatics and further explored the function of PLA genes under cold stress through virus-induced gene silencing (VIGS) experiments.

Results

This study systematically characterized the SlPLA gene family in tomato, identifying 80 genes distributed across 12 chromosomes. Phylogenetic analysis categorized these genes into three groups: pPLA, PLA1, and PLA2. Conserved motifs and gene structure analysis revealed distinct patterns, with some genes lacking untranslated regions (U
