CRISPR-Cas9 knockout of IBH1 fine-tunes brassinosteroid metabolism and modulates plant architecture and grain traits in durum wheat.
Brassinosteroids (BRs) are essential steroidal plant hormones that regulate cell elongation, vascular differentiation and reproductive development, thereby shaping plant architecture and grain yield. Fine-tuning BR signalling, rather than altering hormone accumulation, has been proposed as a potential strategy to regul...
