SHD — Nicotiana attenuata

Summary

A4A49_07017 (SHD, also known as ELF6) in Nicotiana attenuata on chromosome 6 encodes a protein with fructose-bisphosphate aldolase activity (EC 4.1.2.13) and belongs to the Hsp90 family and aldolase TIM barrel domain family. The gene is associated with viral translation, inhibition of cellular response to heat stress, fructose 1,6-bisphosphate metabolism, base-excision repair, vesicle organization, and response to unfolded protein. It is linked to floral organ morphology, seed set percent, submergence tolerance, bacterial and viral disease response, aphid response, photoperiod-sensitive flowering time, gibberellin biosynthesis, and starch grain synthesis. Localization evidence connects the product to the chloroplast outer and inner membranes, plasma membrane, and vesicles. Studies of related genes in other species link the family to thermotolerance, salinity tolerance, broad-spectrum disease resistance, and developmental regulation.
