A Novel Allele in the Promoter of Decreases Gene Expression and Confers Lower Apparent Amylose Contents in Rice ( L.).

is the key gene that controls amylose content (AC), and various alleles have been found in rice populations. is the major allele in and produces moderate AC (15~18%). It was recently found that editing the promoter of could produce a series of alleles that have different Wx activities.

Selection and Validation of 48 KASP Markers for Variety Identification and Breeding Guidance in Conventional and Hybrid Rice (Oryza sativa L.).

Background: Breeding of conventional and hybrid rice (Oryza sativa L.) have solved hunger problems and increased farmers' income in the world. Molecular markers have been widely used in marker-assisted breeding and identification of larger numbers of different bred varieties in the past decades.

Fitness benefits play a vital role in the retention of the Pi-ta susceptible alleles.

In plants, large numbers of R genes, which segregate as loci with alternative alleles conferring different levels of disease resistance to pathogens, have been maintained over a long period of evolution. The reason why hosts harbor susceptible alleles in view of their null contribution to resistance is unclear. In rice, a single copy gene, Pi-ta, segregates for 2 expressed clades of alleles, 1 resistant and the other susceptible.

Phosphorylation-guarded light-harvesting complex II contributes to broad-spectrum blast resistance in rice.

Environmental conditions are key factors in the progression of plant disease epidemics. Light affects the outbreak of plant diseases, but the underlying molecular mechanisms are not well understood. Here, we report that the light-harvesting complex II protein, LHCB5, from rice is subject to light-induced phosphorylation during infection by the rice blast fungus We demonstrate that single-nucleotide polymorphisms (SNPs) in the promoter control the expression of , which in turn correlates with the phosphorylation of LHCB5.

Dynamic Insertion of Pot3 in Prevailing in a Field Rice Blast Population in the Philippines Led to the High Virulence Frequency Against the Resistance Gene in Rice.

The avirulence gene is required for the resistance mediated by its cognate resistance gene , which has been intensively used in rice breeding programs in many Asian countries. However, the sequence diversity of among geographically distinct populations was recently shown to be increasing. Here, we selected a field population consisting of 248 rice blast isolates collected from a disease hotspot in Philippine for the analysis of haplotypes and their pathogenicity against .

Rice tocopherol deficiency 1 encodes a homogentisate phytyltransferase essential for tocopherol biosynthesis and plant development in rice.

RTD1 encodes a homogentisate phytyltransferase catalyzing a key step in rice tocopherol biosynthesis, confers cold tolerance and regulates rice development by affecting the accumulation of DELLA protein SLENDER RICE1. Tocopherols are one of the most important lipid-soluble antioxidants having indispensable roles in living organisms. The physiological functions of tocopherols have been comprehensively characterized in animals and artificial membranes.

Fine mapping and candidate gene analysis of a green-revertible albino gene gra(t) in rice.

Green-revertible albino is a novel type of chlorophyll deficiency in rice (Oryza sativa L.), which is helpful for further research in chlorophyll synthesis and chloroplast development to illuminate their molecular mechanism. In the previous study, we had reported a single recessive gene, gra(t), controlling this trait on the long arm of chromosome 2.

Physiological character and gene mapping in a new green- revertible albino mutant in rice.

A green-revertible albino mutant-Qiufeng M was found from the japonica rice (Oryza sativa L. ssp. japonica) Qiufeng in the field.

[Identification of SSR markers closely linked to eui gene in rice].

Sex determination is a complex regulatory process of early embryogenesis. Embryo must make a developmental decision to develop as a male or female during gonadogenesis. This paper reviews genetic systems of sex determination, gonadogenesis, key genes involved in sex determination of vertebrates.
