Genome-wide identification and characterization of LRR-RLKs reveal functional conservation of the SIF subfamily in cotton (Gossypium hirsutum).

Overall, 543 LRR-RLK genes were identified using genome-wide analysis in cultivated tetraploid cotton G. hirsutum. The present investigation also demonstrated the conserved salt tolerance function of SIF family member in cotton. The GhSIF1 gene can be knocked out using genome editing technologies to improve salt tolerance in cotton.
