LOC101503097 — Cicer arietinum

Summary

LOC101503097 on chickpea chromosome 1 encodes a secretory peroxidase with haem peroxidase and peroxidase domain signatures, and exhibits lactoperoxidase and peroxidase activities, heme binding, and metal binding. The gene is associated with the ascorbate-glutathione cycle, glutathione metabolism, hydrogen peroxide catabolism, detoxification, cell wall modification, secondary metabolism, nitrogen fixation, induced systemic resistance, organogenesis, morphogenesis, root morphogenesis, and responses to boron, salt, and stress. It localises to the vacuole, plant-type cell wall, and extracellular space. The gene is linked to numerous agronomic traits including grain yield per plant, seed weight, biomass yield, leaf chlorophyll content, net photosynthetic rate, water use efficiency, canopy temperature, days to maturity, flower abortion, root fresh and dry weight, shoot dry weight, leaf area index, and contents of lycopene, carotenoid, flavonoid, proline, hydrogen peroxide, soluble protein, and carbohydrate. Studies of related genes in other species connect the family to iron concentration and root morphology traits.
