Oryza sativaWaxyeating and cooking qualityallelic variationIn rice endosperms, the Waxy (Wx) gene is important for amylose synthesis, and various Wx alleles control the amylose content and affect the taste of cooked rice. Herein, we report the cloning of the ancestral allele Wxlv of the Wx ...
The Waxy (Wx) gene product controls the formation of a straight chain polymer of amylose in the starch pathway. Dominance/recessiveness of the Wx allele is associated with amylose content, leading to non-waxy/waxy phenotypes. For a total of 113 foxtail millet accessions, agronomic traits and ...
This hypothesis makes sense if a single mutation or FNP became the prerequisite for cultivation of a landrace as a crop, but only one such gene has been reported in rice: sh4 [19, 20]. All tested landraces and cultivars contain a defective allele of sh4 that reduces seed shattering. If...
However, the well-characterized domestication genes in rice were found to be fixed in both subspecies with the same alleles, thus supporting a single domestication origin6–9,16. Recently, a demo- graphic analysis of single-nucleotide polymorphisms (SNPs) detected from 630 gene fragments suggested ...
previous studies have identified a 200 bp band in thewaxygene of the USland lineage fromP. australis, and a 100 bp DNA fragment specific toP. mauritianus27, confirming its hybrid status. Hybridization betweenP. australisandP. mauritianushas also been observed in Southern Africa in recent ...
rice were found to be fixed in both subspecies with the same alleles, thus supporting a single domestication origin6,7,8,9,16. Recently, a demographic analysis of single-nucleotide polymorphisms (SNPs) detected from 630 gene fragments suggested a single domestication origin of rice17. Meanwhile,...
structure. A strong ancestral gene flow was identified from the roots (except forP. tomentosa) toP. cerasusand from the roots ofP. aviumandP. cerasustoP. fruticosa(Fig.3C, D). Gene flow between these species may have been important in facilitating the rapid diversification of theCerasussubgenus...
(Second row) Wild rice (left) has a panicle that shatters, whereas cultivated rice (rice) has a solid panicle of grain. (Third row) Cultivated wheat with the dominate allele of the Q gene (right) has a condensed and tough spike. Cultivated wheat with the recessive allele q (center) and...
Effectors that are putative determinants of host range were identified; both those that may be involved in race-cultivar and host-species specificity. Since many of the effector candidates are in close proximity to repetitive sequences this may point to a possible mechanism for the effector gene ...
The genetic trait of sourness, or acidity, of melon fruit flesh is conferred by a single dominant locus termed So (Sour) or PH14–16. As all sweet melon accessions are non-acidic, they are homozygous for the recessive mutant, ph/ph. Therefore, the PH gene is intriguing, not only for ...
