SHD — Asparagus officinalis

Summary

A4U43_C05F35030, designated SHD in asparagus (Asparagus officinalis) on chromosome 5, encodes a protein with multiple annotated molecular functions including 2',3'-cyclic-nucleotide 2'-phosphodiesterase, DNA polymerase, transcription regulator and pectate lyase activities, as well as Hsp90 binding. The gene is associated with a wide range of biological processes, including cellular responses to unfolded protein, brassinosteroid stimulus and calcium ions, as well as progesterone anabolism, base-excision repair, and negative regulation of cellulose anabolism. It is linked to numerous agronomically relevant traits, including floral organ morphology, seed set percent, submergence tolerance, bacterial and viral disease responses, temperature stress response, photoperiod-sensitive flowering time, and seed viability. Localisation evidence connects the product to the chloroplast membranes, Tic complex, SCF complex, and cell periphery. Studies of related genes in other species link the family to thermotolerance, broad-spectrum disease resistance, salinity tolerance, and chloroplast envelope maintenance.
