IND — Brassica napus

Summary

BnIND (DARMORV10_C03P39280.1) on chromosome C03 of oilseed rape encodes a basic helix-loop-helix (bHLH) transcription factor of the IND-like family that binds DNA and RNA polymerase II cis-regulatory regions, dimerizes with proteins, and localizes to the nucleus. This gene is associated with carpel and gynoecium development, polar nucleus fusion, flower development, and regulation of flowering under both short-day and long-day photoperiods. It is also linked to auxin anabolism, pectin breakdown, ABA signaling, circadian rhythm, response to red light and cold, and downregulation of seed germination. Traits associated with BnIND include flowering time, fruit length, seed growth and development, flower number, leaf size, root thickness, chlorophyll content, trichome morphology, and seedling hypocotyl length. Related genes in other species are linked to silique dehiscence, valve margin development, replum formation, seed shattering, and fruit patterning.
