LC — Asparagus officinalis

Summary

A4U43_UNF10700, designated LC and also known as AoBHLH18, encodes a basic helix-loop-helix (bHLH) transcription regulator on asparagus chromosome KV864086. The product possesses protein dimerization activity, sequence-specific DNA binding, and transcription cis-regulatory region binding, consistent with its nuclear localization. In asparagus, this gene is associated with the regulation of primary metabolic processes, anthocyanin and flavonoid anabolism, DNA-dependent transcription, and defense responses. It has also been linked to photosynthetic rate. Studies of related genes in other species connect the family to a wide range of traits including drought tolerance, plant height, root length, fruit shape, chlorophyll content, and water use efficiency, though these associations are not yet established in asparagus.
