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

“…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 ).…”

“…Due to translational reinitiation in the main open reading frame N-terminally truncated DELLA proteins are produced, which are resistant to GA-mediated degradation. This causes a lower reduction of the growth repressing DELLA proteins and plants remain short (Peng et al 1999;Van De Velde et al 2021). The Rht1 genes in uence a multitude of agronomically relevant traits that contribute to yield and grain quality, for instance coleoptile size and seed emergence, grain number per spikelet, seed size, protein content and grain yield (Acuña et al 2001;Flintham et al 1997).…”
