CAB1 — Capsicum annuum

Summary

T459_05316, also known as CaCAB1, encodes a chlorophyll a-b binding protein located in the chloroplast thylakoid membrane. This gene is associated with chlorophyll binding and metal binding, and is linked to photosynthesis, specifically light harvesting in photosystem I and II. CaCAB1 has been connected to both chlorophyll anabolism and breakdown, as well as pigmentation, phenylpropanoid and flavonoid metabolism, and response to light stimulus. It is also associated with virus-induced post-transcriptional gene silencing and homeostasis. In terms of traits, CaCAB1 is linked to fruit color, quantum yield, net photosynthetic rate, and chlorophyll content. Studies of related genes in other species further connect this family to light-harvesting functions.
