Natural variation in OsMYB305 downregulating cytokinin‐mediated inhibition of leaf senescence contributes to regional adaptation in rice

open access: yesNew Phytologist, EarlyView.
Proposed regulatory model of OsMYB305 in leaf senescence. Summary Accumulating evidence has identified transcription factors (TFs) as key regulators of the onset and progression of leaf senescence. However, the regulatory role of the rice myeloblastosis (MYB) TF OsMYB305 in this process remains largely unknown.

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

open access: yes, 2013
Genetic 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 ...

Structural Variations Contribute to Subspeciation and Yield Heterosis in Rice

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Yield heterosis has been extensively exploited in hybrid breeding, with intersubspecific hybrids often exhibiting the most pronounced effects. However, developing elite hybrids remains a laborious and time‐consuming process. The genetic basis of heterosis has been debated for over a century, hindered largely by the lack of high‐quality genomes.

A Repertoire of Major Genes From Crop Wild Relatives for Breeding Disease‐Resistant Wheat, Rice, Maize, Soybean and Cotton Crops

open access: yesPlant Breeding, EarlyView.
ABSTRACT Global food demand is predicted to rise anywhere from 59% to 98% by 2050 because of increasing population. However, the continued depletion of natural resources and increasing biotic and abiotic stresses will continue to pose significant threats to global food security in coming years.

The complete mitochondrial genome of upland rice (Oryza sativa) in southwest of China

open access: yesMitochondrial DNA. Part B. Resources, 2019
We sequenced complete mitochondrial genome of upland rice Oryza sativa (Liliopsida: Poales: Poaceae) with length of 444,883 bp. The genome has similar codon usage and gene organization to those of mitogenome reported for other Poales.

Genome-wide analysis of rice dehydrin gene family: Its evolutionary conservedness and expression pattern in response to PEG induced dehydration stress. [PDF]

open access: yesPLoS ONE, 2017
Abiotic stresses adversely affect cellular homeostasis, impairing overall growth and development of plants. These initial stress signals activate downstream signalling processes, which, subsequently, activate stress-responsive mechanisms to re-establish ...

Fendioxypyracil, a new and systemic PPO‐inhibiting herbicide for X‐spectrum weed control

open access: yesPest Management Science, Volume 82, Issue 7, Page 6794-6807, July 2026.
This graphical abstract presents the discovery and synthesis of PPO herbicide structures with a central pyridine core, showing molecular conformations, dose–response inhibition curves for PPO1 and PPO2, and comparative weed and grass control efficacy of fendioxypyracil versus other herbicides in greenhouse and field trials.

Mapping of quantitative trait loci for fiber and lignin contents from an interspecific cross Oryza sativa × Oryza rufipogon [PDF]

open access: yesJournal of Zhejiang University SCIENCE B, 2011
Rice straw is always regarded as a by-product of rice production, but it could be a significant energy source for ruminant animals. Knowledge of the genetic variation and genetic architecture of cell wall traits will facilitate rice breeders by improving relevant traits through selective breeding and genetic engineering.

QTL Mapping for Plant Height Using Introgression Lines Derived from Zhonghui 8015 and Wild Rice (Oryza rufipogon)

open access: yesRice Science, 2022
Many excellent genes in wild rice have been lost during the domestication of wild rice to cultivated rice. In this study, introgression lines (ILs) were produced with a wild rice (Oryza rufipogon) accession, BJ194, as a donor parent and an indica ...
