Linking differential domain functions of the GS3 protein to natural variation of grain size in rice (2010, background): “Although a number of QTLs for tillering (10), grain number (11, 12), grain size (8, 13–15), and panicle size and plant architecture (16–18) have been cloned, molecular characterization of these and many more genes is needed to understand the genetic and molecular bases of yield (9).”
Archaeogenetic study of prehistoric rice remains from Thailand and India: evidence of early japonica in South and Southeast Asia (2016, background): “Nuclear markers also hold the potential to assess directly the presence or absence of key functional alleles, for agronomic traits or domestication traits, such as seed shattering (qsh1, sh4), seed width (qsw5), seed pericarp colour (rc), waxy (wx) and plant height (sd1) (Konishi et al. 2006; Lin et”
The molecular genetics of crop domestication. (2006, neutral): “Grain number differences between rice varieties are controlled by grain number1 (gn1), which encodes an oxidase/ dehydrogenase that degrades the plant hormone cytokinin (Ashikari et al., 2005).”
Breeding high-yield superior quality hybrid super rice by rational design (2016, neutral): “The Gn1a allele from Habataki which increased grain number per plant by ∼21% and grain yield by 10% [19] was subsequently detected in restorer line R1128, a parental line of hybrid rice that has giant panicles.”
Raising yield potential of wheat. III. Optimizing partitioning to grain while maintaining lodging resistance. (2011, background): “Furthermore, at least one candidate gene for spike fertility already exists in rice (Gn1a) coding for cytokinin oxidase, which through its regulation of cytokinin levels influences the number of reproductive organs in the panicle (Ashikari et al., 2005).”
AMMI Biplot Analysis for Stability of Grain Yield in Hybrid Rice (Oryza sativa L.) (2014, background): “6 billion by 2050 [3] which will demand more than 50% of rice needs to be produced what is produced present to cope with the growing population [4,5].”
Progress in the genetic understanding of plant iron and zinc nutrition (2006, background): “2005), as well as the gene controlling an important QTL for grain yield in rice (Ashikari et al. 2005).”
