| Abstract |
Starch biosynthesis is one of the most important pathways that determine both grain quality and yield in rice (Oryza sativa L.). Sugary endosperm, sugary-1 (sug-1), is a mutant trait for starch biosynthesis. Rice plants carrying sug-1 produce grains that accumulate water-soluble carbohydrates instead of starch, even after maturity. Although this trait enhances the diversity of grain quality, sugary endosperm rice has hardly been commercialized due to the severely wrinkled grains and subsequent problems in milling. This study was conducted to identify the genes responsible for the sug-h phenotype through a map-based cloning technology. We induced a mild sugary mutant, sugary-h (sug-h) through the chemical mutagenesis on the Korean japonica cultivar Hwacheong. Grains of the sug-h mutant were translucent and amber-colored, and the endosperm appeared less wrinkled than sug-1, whereas the soluble sugar content was fairly high. These characteristics confer greater marketability to the sug-h mutant. Genetic analyses indicated that the sug-h mutant phenotype was controlled by a complementary interaction of two recessive genes, Isoamylase1 (OsISA1), which was reported previously, and Starch branching enzyme IIa (OsBEIIa), which was newly identified in this study. Complementation tests indicated that OsBEIIa regulated the properties of sugary endosperm. Complementary interactions between the starch biosynthesis genes OsISA1 and OsBEIIa determine the mild sugary endosperm mutant, sugary-h, in rice. Our finding may facilitate the breeding of sugaryendosperm rice for commercial benefit. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 25 July 2017.
All research outputs
#15,470,944
of 22,990,068 outputs
Outputs from Rice
#175
of 388 outputs
Outputs of similar age
#198,134
of 315,207 outputs
Outputs of similar age from Rice
#4
of 8 outputs
Altmetric has tracked 22,990,068 research outputs across all sources so far. This one is in the 22nd percentile – i.e., 22% of other outputs scored the same or lower than it.
So far Altmetric has tracked 388 research outputs from this source. They receive a mean Attention Score of 3.8. This one is in the 41st percentile – i.e., 41% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 315,207 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 28th percentile – i.e., 28% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 8 others from the same source and published within six weeks on either side of this one. This one has scored higher than 4 of them.
