Overexpression of Enhances Rice Tolerance to Sheath Blight Caused by .

Sheath blight (ShB), caused by the necrotrophic fungus (), poses severe threats to global rice production. Developing a resistant variety with an ShB-resistance gene is one of most efficient and economical approaches to control the disease. Here, we identified a highly conserved chloroplast-localized stem-loop-binding protein encoding gene (), which shows great potential in developing an ShB-resistant variety.

Natural variation in SBRR1 shows high potential for sheath blight resistance breeding in rice.

Sheath blight (ShB), caused by necrotrophic fungus Rhizoctonia solani, is one of the most serious rice diseases worldwide. To the best of our knowledge, no genes with high potential for rice ShB resistance breeding have been previously characterized. Here we identify a ShB resistance receptor-like kinase 1 (SBRR1) gene via a genome-wide association study.

Molecular Insights into Rice Immunity: Unveiling Mechanisms and Innovative Approaches to Combat Major Pathogens.

Rice () is a globally important crop that plays a central role in maintaining food security. This scientific review examines the critical role of genetic disease resistance in protecting rice yields, dissecting at the molecular level how rice plants detect and respond to pathogen attacks while evaluating modern approaches to developing improved resistant varieties. The analysis covers single-gene-mediated and multi-gene resistance systems, detailing how on one hand specific resistance proteins, defense signaling components, and clustered loci work together to provide comprehensive protection against a wide range of pathogens and yet their production is severely impacted by pathogens such as (bacterial blight) and (rice blast).

Isolation of , a Peptidase_M24 Superfamily Gene, Regulating Heading Date in Rice.

The heading date is one of the important traits in rice, which greatly affects grain yield and regional adaptability. Although the flowering pathways in rice have been extensively investigated, the genes involved in flowering remain largely unknown. Here, we report a rice mutant, which showed late flowering under both long-day (LD) and short-day (SD) conditions.

Fine mapping and candidate gene analysis of qSB12, a gene conferring major quantitative resistance to rice sheath blight.

qSB12, a major quantitative sheath blight resistance gene originated from rice variety YSBR1 with good breeding potential, was mapped to a 289-Kb region on chromosome 12. Sheath blight (ShB), caused by Rhizoctonia solani kühn, is one of the most serious global rice diseases. Rice resistance to ShB is a typical of quantitative trait controlled by multiple quantitative trait loci (QTLs).

Naturally aged polylactic acid microplastics stunted pakchoi (Brassica rapa subsp. chinensis) growth with cadmium in soil.

Biodegradable microplastics (BMPs) and cadmium (Cd) are posing threats to agro-systems especially to plants and current studies mostly used virgin BMPs to explore their ecological effects. However, effects of naturally aged BMPs and their combined effects with Cd on pakchoi are yet to be unraveled. Therefore, this study incubated naturally aged polylactic acid (PLA) MPs through soil aging process and investigated the single and combined effects of Cd and PLA MPs (virgin and aged) on pakchoi (Brassica rapa subsp.

Identification of Elite -Gene Combinations against Blast Disease in Rice Varieties.

Rice blast, caused by the fungus, is one of the most devastating rice diseases worldwide. Developing resistant varieties by pyramiding different blast resistance () genes is an effective approach to control the disease. However, due to complex interactions among genes and crop genetic backgrounds, different -gene combinations may have varying effects on resistance.

Ontogenetic moulting behavior of the Cambrian oryctocephalid trilobite .

Moulting behaviors in trilobites are a crucial strategy during development. Previous studies have demonstrated inter-and intraspecific variability of moulting behavior in trilobites. Currently, ecdysial motifs for trilobites are considered not stable even within species and fewer detailed studies dealt with moulting behaviors in a single species of trilobite during development.
