Substitution Mapping and Allelic Variations of the Domestication Genes from O. rufipogon and O. nivara [PDF]

Rice, 2023
Background Domestication from wild rice species to cultivated rice is a key milestone, which involved changes of many specific traits and the variations of the genetic systems. Among the AA-genome wild rice species, O. rufipogon and O.

Phenological and morphological variations of Oryza rufipogon and O. nivara in Sri Lanka and their evolutionary implications [PDF]

Scientific Reports
Phenological and morphological variation are widely viewed as a pivotal driver of ecological adaptation and speciation. Here, we investigate variation patterns of flowering phenology and morphological traits within and between O. rufipogon and O.

Local differentiation amidst extensive allele sharing in Oryza nivara and O. rufipogon. [PDF]

Ecol Evol, 2013
AbstractGenetic variation patterns within and between species may change along geographic gradients and at different spatial scales. This was revealed by microsatellite data at 29 loci obtained from 119 accessions of three Oryza series Sativae species in Asia Pacific: Oryza nivara Sharma and Shastry, O. rufipogon Griff., and O. meridionalis Ng.

Comprehensive genetic diversity revealed in the pre-breeding RILs (O. sativa × O. rufipogon) with enhanced yield and pigmented grain quality [PDF]

Frontiers in Genetics
Developing high-yielding rice varieties (Oryza sativa L.) is critical to ensure global food security. The narrow genetic base in the released rice varieties has plateaued the improvement.

Morphological and molecular dissection of wild rices from eastern India suggests distinct speciation between O. rufipogon and O. nivara populations. [PDF]

Sci Rep, 2018
AbstractThe inter relationships between the two progenitors is interesting as both wild relatives are known to be the great untapped gene reservoirs. The debate continues on granting a separate species status to Oryza nivara. The present study was conducted on populations of Oryza rufipogon and Oryza nivara from Eastern India employing morphological ...

Crossability analysis of cultivated rice (Oryza sativa) with O. rufipogon and O. longistaminata and F1-identification

The Indian Journal of Agricultural Sciences, 2023
The research was conducted at Instructional cum Research (ICR) farm in Assam Agricultural University, Jorhat, Assam for the year 2019–21 with the objective to determine the crossability of wild rice species O. longistaminata and O.

Finding a novel QTL responsible for kernel cracking resistance from CSSLs of 'Itadaki' (O. sativa L.) × donor O. rufipogon. [PDF]

Breed Sci, 2020
To find new QTLs responsible for kernel cracking resistance, we screened 50 CSSLs derived from the moderately resistant cultivar 'Itadaki' (O. sativa L.) and the donor O. rufipogon. Two lines, IRSL 30 and IRSL 37, were selected as resistant. QTL analyses of the percentage of cracked kernels (PCK) in F4 individuals derived from "Itadaki/IRSL 30" and ...

Adaptation of morphological traits and anatomy structure related to Cd spatial distribution in wild rice Oryza officinalis and Oryza rufipogon roots [PDF]

BMC Plant Biology
Background Excessive cadmium (Cd) accumulation in rice poses significant risks to public health. Wild rice as the ancestor of cultivated rice is regarded as a treasure trove of rice germplasm resources. Two wild rice Oryza officinalis Wall.

Pan-genome of wild and cultivated rice uncovers genetic diversity, lost and selected sequences during rice domestication [PDF]

Rice
Wild relatives of crops are pivotal genetic reservoirs for enhancing stress resistance and yield of cultivated varieties. Rice (Oryza sativa L.) domestication had led to the loss of numerous beneficial traits from wild rice, especially in the AA genome ...

Development of introgression lines of AA genome Oryza species, O. glaberrima, O. rufipogon, and O. nivara, in the genetic background of O. sativa L. cv. Taichung 65. [PDF]

Breed Sci, 2019
To evaluate and utilize potentially valuable quantitative trait loci or genes of wild relatives in the genetic background of domesticated crop species, chromosome segment substitution lines (CSSLs) are a valuable tool. CSSLs can be constructed through the exchange of chromosome segments of AA genome species of the genus Oryza with cultivated rice ...
