Abstract: The unprecedented wheat yield increases during the Green Revolution were achieved through the introduction of the Reduced height (Rht)-B1b and Rht-D1b semi-dwarfing alleles. These Rht-1 alleles encode growth-repressing DELLA genes containing a stop codon within their open reading frame that confers gibberellin (GA)-insensitive semi-dwarfism. In this study, we successfully took the hurdle of detecting wild-type RHT-1 proteins in different wheat organs and confirmed their degradation in response to GAs. We furth… Show more

“…Among several phytohormones regulating plant height, gibberellin (GA) was most documented and characterized. GR genes Rht‐B1b and Rht‐D1b encode DELLA proteins truncated in the N‐terminal DELLA domain and can constitutively repress plant growth and development mediated by GA (Peng et al ., 1999; Van De Velde et al ., 2021). DELLA protein is an integrator of numerous development pathways and interacts with phytochrome interacting factors (PIFs), key regulators responsible for GA induction (Boccaccini et al ., 2014).…”

“…Two new alleles, Rht-D1n1 and Rht-D1n2 , corresponding to the second and third largest clusters, were identified with mutations in upstream regions located 383 bp and 2,640 bp, respectively, from the start codon ( Figure 5D ). Both of the semi-dwarfing alleles Rht-B1b and Rht-D1b contained stop-gain mutations ( Figure 5, E and F ), which produced N-terminal truncations through translational reinitiation ( Van De Velde et al, 2021 ). Several accessions identified as harboring Rht-B1h alleles were confirmed by resequencing data to be consistent with known variation forms ( Figure 5E ).…”

“…The DELLA proteins encoded by the Rht-B1b and Rht-D1b genes reduced the wheat plant height by altering GA sensitivity ( Peng et al, 1999 ). Translational reinitiation of the main open reading frame of these two genes was shown to block the GA signaling pathway, and this effect was determined to be dominant ( Van De Velde et al, 2021 ). There is an Rht-B1b allele in WT plants and an Rht-B1a allele in qd mutants ( Zhang et al, 2016 ).…”
