Breeding high-yield superior quality hybrid super rice by rational design (2016, positive): “At least eleven QTLs including Ghd7, DTH8, GS3, GW2, sd1, TGW6, HTD1, IPA1, GL7(GW7), GS2 and Gn1a [19,53–66] have been identified to play an important role in these hybrid rice varieties (Table 1).”
Comprehending crystalline β-carotene accumulation by comparing engineered cell models and the natural carotenoid-rich system of citrus (2011, neutral): “In contrast to the recessive semi-dwarf sd-1 Green Revolution allele in rice, that is a loss-of-function mutation in one of the major GA biosynthetic genes (GA 20-oxidase2 or GA20ox2) (Monna et al., 2002; Sasaki et al., 2002; Spielmeyer et al., 2002), the wheat reduced height Rht-B1b and Rht-D1b Gre”
Through the genetic bottleneck: O. rufipogon as a source of trait-enhancing alleles for O. sativa (2007, background): “The cloning of the sd1 gene was simultaneously reported by multiple groups (Ashikari et al. 2002; Monna et al. 2002; Sasaki et al. 2002; Spielmeyer et al. 2002).”
Genome Editing of Plants (2017, methodology): “The sd-1 gene was isolated using two different strategies that included positional cloning (Monna et al., 2002) and use of the indica sd-1 gene sequence (Spielmeyer et al., 2002).”
