NPH3 — Cicer arietinum

Summary

CaNPH3 (LOC101506769) on chickpea chromosome 6 encodes a protein with an NPH3/RPT2-like domain and a BTB/POZ domain, and possesses FMN binding, blue light photoreceptor activity, GTPase activity, and protein serine/threonine kinase activity. The gene is associated with chloroplast accumulation movement, root hair cell differentiation, plant organ morphogenesis, endosperm development, multidimensional cell growth, positive gravitropism, and regulation of root meristem size. It is linked to the response to red or far-red light and inhibition of brassinosteroid-mediated signalling. CaNPH3 has been connected to agronomically important traits including biomass yield, seed yield, photosynthetic rate, water use efficiency, days to flowering, germination rate, nitrate uptake, and root mass density. It is also associated with phototropism, blue and red light sensitivity, and viral disease response.
