PS1 — Asparagus officinalis

Summary

A4U43_C03F20870, designated AoPS1 on asparagus chromosome 3, encodes a presenilin family protein with aspartic endopeptidase activity and intramembrane cleaving function. The gene is associated with the N signaling pathway, ectodomain cleavage, and protein processing. It has been connected to response to heat and memory processes. The encoded protein localizes to the presenilin complex, endoplasmic reticulum and Golgi membranes, plant-type vacuole, nucleus, and extracellular space. AoPS1 is linked to photosynthetic rate, respiration rate, and root mass density traits. It is also associated with root hair elongation, phosphate starvation response, and phosphate utilization phenotypes. Related genes in other species link the presenilin family to protein conservation, while broader sequence similarity connections associate the family with amylose content, net photosynthetic rate, transpiration rate, and stomatal resistance traits.
