Abstract

Heat shock transcription factors (Hsf-s) have been considered one of the major regulatory proteins that play important roles in various biological processes during the growth and development of plants. Unfortunately, no comprehensive studies of the Hsf family in papaya (Carica papaya), a popular tropical fruit crop, have been performed, even the papaya genome assembly has been released recently. In this study, a total of 18 members of the Hsf family, namely CpHsf-s have been identified in papaya. Based on various computational tools, a systematic characterization of the CpHsf family, such as gene structure, physic-chemical features, categorization, and protein-protein interaction, has been conducted. We found that the physic-chemical properties of the CpHsf proteins were highly variable, while all proteins were hydrophilic and localized in the nucleus. Our classification indicated that the CpHsf proteins could be categorized into three groups, including HsfA, HsfB, and HsfC, and members in the same clade share similar gene structure. According to the previous RNA-Seq datasets, our re-analysis revealed that the CpHsf genes exhibited different expressions in various major organs or tissues during fruit ripening and under the ultra-low temperature stress. Taken together, our study could provide a list of candidate genes for further functional characterization towards the improvement of stress tolerance in papaya.

Abstract

This study investigates the phospholipase A (PLA) superfamily in cocoa (Theobroma cacao), providing a comprehensive analysis of its genomic organization, structural diversity, and functional roles. A total of 19 PLA1 and 20 PLA2 genes were identified, with detailed assessments of their chromosomal locations, protein properties, and exon-intron structures. Phylogenetic analysis established evolutionary relationships with PLA proteins from other species, such as Arabidopsis thaliana and rice (Oryza sativa). Of our interest, transcriptomic profiling under biotic stress caused by Phytophthora megakarya infection and during embryo development revealed distinct expression patterns, demonstrating the involvement of PLA genes in stress responses and key developmental processes. Taken together, these findings provide valuable insights into the roles of PLA genes in cacao biology and offer a foundation for future applications to improve cacao’s resilience and productivity through genetic and biotechnological strategies.
