CA1 — Solanum lycopersicum

Summary

SlCA1 (CA1) on tomato chromosome 2 encodes a beta-type carbonic anhydrase belonging to clade B, with additional annotated molecular functions including salicylic acid binding, peroxidase activity, calcium ion binding, mRNA binding, zinc binding, and protein binding. The gene is associated with carbon dioxide response, gas transport, oxygen metabolism, chlorophyll a anabolism, upregulation of photosynthesis, negative regulation of stomatal complex development, oxidative phosphorylation, and S-nitrosylation. It localises to the chloroplast thylakoid membrane, stroma, envelope, stromule, apoplast, endosome, mitochondria, and cytosol. SlCA1 is linked to numerous agronomic traits including net photosynthetic rate, transpiration rate, stomatal resistance, quantum yield, chlorophyll content, lycopene content, starch content, shoot fresh and dry weight, plant height, root length, leaf number, nitrogen content, proline content, hydrogen peroxide content, leaf water potential, and salt tolerance. It has also been connected to drought tolerance, carbon fixation, stomatal development and movement, immunity, cold response, and mitochondrial complex I assembly.
