Genome-wide identification and functional characterization of the <i>CP12</i> gene family in cotton reveals its critical role in heat stress response.

ABSTRACT:

Introduction

Calvin Cycle Protein 12 (CP12) is a key regulator of the Calvin-Benson-Bassham (CBB) cycle that mediates CO₂ assimilation through dark/light modulation. Beyond its canonical role, emerging evidence indicates that CP12 may also function as a molecular chaperone and participate in plant stress responses. However, its gene family characteristics and roles under heat stress remain unclear in cotton.

Methods

We performed a genome-wide identification and characterization of the CP12 gene family in four cotton species (Gossypium hirsutum, G. barbadense, G. arboreum, and G. raimondii). Phylogenetic classification, conserved motif analysis, gene structure, synteny, and promoter cis-element analyses were conducted. Transcriptome datasets from flowers, leaves
