Assessment of partial resistance to rice blast disease
ORYZA- An International Journal on Rice, 2018Assessment of resistance in any plant pathosystem involves the measurement, growth and development of the pathogen in the host under the influence of the environment. Partial resistance is generally a quantitative measure of disease progress over time and thus can be assessed quantitatively by means of (i) analysis of components of resistance, (ii ...

Durable resistance to rice blast disease — environmental influences
Euphytica, 1992Blast is one of the most serious diseases of rice worldwide. The pathogen,Pyricularia grisea, can infect nearly all parts of the shoot and is commonly found on the leaf blade and the panicle neck node. Host resistance is the most desirable means of managing blast, especially in developing countries.

Status on Genetic Resistance to Rice Blast Disease in the Post-Genomic Era
PlantsRice blast, caused by Magnaporthe oryzae, is a major threat to global rice production, necessitating the development of resistant cultivars through genetic improvement. Breakthroughs in rice genomics, including the complete genome sequencing of japonica and indica subspecies and the availability of various sequence-based molecular markers, have greatly

Euphytica, 2017
This review on the resistance to wheat blast disease focus on the latest knowledge useful for the breeders, but also takes into account the lacks in these knowledge. To tackle this disease, it is relevant to apply a breeding strategy which has previously proven its efficacy for obtaining rice varieties with a high level of partial and durable ...

Investigating the biology of rice blast disease and prospects for durable resistance
2021There are important biological process involved in rice blast disease that are now well-studied during the early events in plant infection which include: the cell biology of appressorium formation, the biology of invasive growth and effector secretion, the two distinct mechanisms of effector secretion, the nature of the plant-pathogen interface, PAMP ...

Utilizing Host-Plant Resistance to Circumvent Blast Disease in Rice
2021Blast is one of the devastating diseases of rice which cause significant yield losses. Blast is mainly managed by the use of fungicides. However, this approach is not eco-friendly and causes health hazards. Basmati is the specialty rice of India with great export potential.

Cytology of Infection and Host Resistance in Rice Blast Disease
2004Rice blast disease caused by Pyricularia oryzae Cav. (telemorph: Magnaporthe grisea (Hebert) Barr) is the most widespread and damaging disease of cultivated rice in both tropical and temperate zones. Studies have been made to forecast the occurrence of the disease, breed blast resistant lines, and control the disease by chemicals.

Pathogen Variability and Host Resistance in Rice Blast Disease
Annual Review of Phytopathology, 1980Almost 90 years have passed since Cavara described the fungus Pyricularia oryzae, which causes rice blast disease. Rice blast occurs in all major rice growing regions of the world and accounts for devastating epidemics and a considerable decrease each year in rice production.

Identification of Some Rice Genotypes Resistant to Blast Disease in Egypt
British Biotechnology Journal, 2014Blast disease caused byPyricularia oryzae, is the most important disease of rice in Egypt and in the world. Field surveys in main production regions, revealed that the highest disease incidence was recorded i n El-Behera Governorate. Seven rice cultivars were screened for resistance to blast disease.
