Differential proteomic analysis reveals key players in rice resistance to Rhizoctonia solani pathogenesis.

Rhizoctonia solani is a necrotrophic fungus that causes sheath blight (ShB) in rice, resulting in substantial yield losses. A major challenge in managing this disease is the lack of fully resistant rice varieties. While some germplasms show partial resistance, the underlying mechanisms remain poorly understood.

Transmission of Cryphonectria Hypovirus 1 (CHV1) to and In Vitro and In Vivo Testing of Its Potential for Use as Biocontrol Against .

Cryphonectria hypovirus 1 (CHV1) is successful in controlling , the causal agent of chestnut blight, but little is known regarding its transmission to other fungi, for example the European . In this study, CHV1 was transmitted (circa 200,000-800,000 copies/microliter) to seven isolates from infected . Reverse transmission to virus-free (European 74 testers collection) was achieved, although it was less successful (250-55,000 copies/µL) and was dependent on the vegetative compatibility (VC) group.

Forecasting of Airborne Conidia Quantities and Potential Insect Associations of , the Causal Agent of Chestnut Blight, in England.

Sweet chestnut, an Asiatic tree introduced in many parts of Europe including the United Kingdom, is planted for nut production, timber, and amenity. Its major threat is the disease called blight, caused by the fungus , which infects through wounds by airborne spores. Field trapping using sticky rods rotating traps was performed in an infected area in Devon (between May 2021 and April 2023).

Detections in England, Jersey, and Guernsey during 2020-2023 Reveal Newly Affected Areas and Infections by the CHV1 Mycovirus.

In England, was detected for the first time in 2011 in a nursery and in 2016 in the wider environment. Surveys between 2017 and 2020 identified the disease at different sites in Berkshire, Buckinghamshire, Cornwall, Derbyshire, Devon, Dorset, London, West Sussex, and the island of Jersey, while the present study comprises the results of the 2020-2023 survey with findings in Derbyshire, Devon, Kent, Nottinghamshire, Herefordshire, Leicestershire, London, West Sussex, and the islands of Jersey and Guernsey. A total of 226 suspected samples were collected from 72 surveyed sites, as far north as Edinburgh and as far west as Plymouth (both of which were negative), and 112 samples tested positive by real-time PCR and isolation from 35 sites.

Comparative transcriptome profiling reveals the basis of differential sheath blight disease response in tolerant and susceptible rice genotypes.

Rice sheath blight (ShB) disease, caused by the fungal pathogen Rhizoctonia solani AG1-IA, is one of the devastating diseases and causes severe yield losses all over the world. No completely resistant germplasm is known till now, and as a result, the progress in resistance breeding is unsatisfactory. Basic studies to identify candidate genes, QTLs, and to better understand the host-pathogen interaction are also scanty.

Seed Biopriming With Strains Isolated From Tree Bark Improves Plant Growth, Antioxidative Defense System in Rice and Enhance Straw Degradation Capacity.

This study is a unique report of the utilization of strains collected from even tree barks for rice plant growth, its health management, and paddy straw degradation. Seven different spp. of were characterized according to morphological and molecular tools.

Improved photosystem II and defense enzymes activity in rice (Oryza sativa) by biopriming against Xanthomonas oryzae pv. oryzae.

Bacterial blight (BB), caused by Xanthomonas oryzae pv. oryzae (Xoo) is a major threat to rice production as it accounts for loss up to 50% of annual rice grain yield. Xoo causes leaf tissue necrosis and as a result there is downregulation of the photosynthetic mechanisms of plant.

Tissue Tolerance Coupled With Ionic Discrimination Can Potentially Minimize the Energy Cost of Salinity Tolerance in Rice.

Salinity is one of the major constraints in rice production. To date, development of salt-tolerant rice cultivar is primarily focused on salt-exclusion strategies, which incur greater energy cost. The present study aimed to evaluate a balancing strategy of ionic discrimination tissue tolerance, which could potentially minimize the energy cost of salt tolerance in rice.
