Rice Blast: A Disease with Implications for Global Food Security

Agronomy, 2019
Rice blast is a serious fungal disease of rice (Oryza sativa L.) that is threatening global food security. It has been extensively studied due to the importance of rice production and consumption, and because of its vast distribution and destructiveness ...

TaHDA1‐mediated histone and non‐histone deacetylation orchestrates drought tolerance in wheat

Journal of Integrative Plant Biology, EarlyView.
The histone deacetylase TaHDA1 is a key regulator linking histone and non‐histone deacetylation with drought adaptation and a potential target for improving drought resilience and grain nutritional quality in wheat. ABSTRACT Drought stress severely constrains wheat (Triticum aestivum L.) growth and productivity.

Characterization of Six Partial Resistance Genes and One Quantitative Trait Locus to Blast Disease Using Near Isogenic Lines with a Susceptible Genetic Background of Indica Group Rice (Oryza sativa)

PhytoFrontiers, 2022
Seven near isogenic lines (NILs) for six partial blast-resistance genes—Pi35, pi21, Pi37(t)(Pi37-KRIL17), Pb1, and Pi34 (two: Pi34-Chubu32 and Pi34-Chugoku40, originating from different Japonica Group rice lines, ‘Chubu 32’ and ‘Chugoku 40’, respectively)

Structural Variations Contribute to Subspeciation and Yield Heterosis in Rice

Plant 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.

Detection of white head symptoms of panicle blast caused by Pyricularia oryzae using cut-flower dye

Plant Methods, 2019
Background Breeding of rice with panicle resistance to rice blast disease caused by Pyricularia oryzae is a challenge towards sustainable rice production. Methods for accurate estimation of disease severity can support breeding. White head symptoms are a

Time‐series multi‐omics analysis of micronutrient stress in Sorghum bicolor reveals iron and zinc crosstalk and regulatory network conservation

Plant Biology, EarlyView.
Overlap between Fe and Zn responsive gene regulatory networks (GRNs) were found, indicative of micronutrient crosstalk, and conservation of root and leaf GRNs and genes suggests strong constraint on homeostasis networks in plants. Abstract Micronutrient stress impacts growth, biomass production, and grain yield in crops.

Pyramiding of Pi46 and Pita to improve blast resistance and to evaluate the resistance effect of the two R genes

Journal of Integrative Agriculture, 2016
Utilization of R (resistance) genes to develop resistant cultivars is an effective strategy to combat against rice blast disease. In this study, R genes Pi46 and Pita in a resistant accession H4 were introgressed into an elite restorer line Hang-Hui-179 (

Auxin‐related regulation of barley floral organ fate: genetic and phenotypic insights from tweaky spike mutants

New Phytologist, Volume 252, Issue 3, Page 1166-1180, November 2026.
Inflorescence/floret phenotypes of tweaky spike (tw) barley (Hordeum vulgare) mutants and their respective WT backgrounds. Summary Mutant‐based research is a cornerstone for elucidating gene function in barley (Hordeum vulgare) and other cereals. In this study, we exploited a unique collection of barley tweaky spike (tw) mutants to identify the locus ...
