Blast disease and wheat production in Brazil

open access: yesPesquisa Agropecuária Brasileira, 2022
Abstract This review paper presents the current context of wheat production in Brazil, the management strategies to reduce yield losses due to blast, and the biotechnological approaches to improve wheat resistance. Wheat blast or brusone is caused by the Magnaporthe oryzae Triticum (MoT) pathotype fungus that can infect all the aboveground parts of the

Deciphering Genotype-By-Environment Interaction for Target Environmental Delineation and Identification of Stable Resistant Sources Against Foliar Blast Disease of Pearl Millet

open access: yesFrontiers in Plant Science, 2021
Once thought to be a minor disease, foliar blast disease of pearl millet, caused by Magnaporthe grisea, has recently emerged as an important biotic constraint for pearl millet production in India.

Biochemical Studies on the Rice Blast Disease

open access: yesJournal of the agricultural chemical society of Japan, 1957
47菌株の稲熱病菌を用いてT. C. A-cycleに関与する有機酸塩の利用度,セルローズ利用度,ペクチナーゼの差異並びに北大農学部菌株のNo. 1及びNo. 2のビオチン生成量等の試験を行い次の如き結果を得た. (1) ビオチンを要求しないNo. 1及びNo. 2をビオチン欠合成培地で培養してビオチン生成能の有無を検した.即ち培養濾液及び洗滌菌体の酸加水分解物についてBioassayでビオチン量を試験した結果,ビオチン生成能は認められなかった.此等の菌株は糖代謝の型式が他の菌株とは異るものと考えられる. (2) 炭素源としてはコハク酸,フマール酸,クエン酸の利用度並びに此等の酸に1/100Mマロン酸を添加した培地の利用度に就て試験した結果, 9菌株に就てはT. C.

Genetic Structure of the Rice Blast Pathogen (Magnaporthe oryzae) over a Decade in North Central California Rice Fields. [PDF]

open access: yes, 2017
Rice blast, caused by the ascomycete Magnaporthe oryzae, is one of the most destructive rice diseases worldwide. Even though the disease has been present in California since 1996, there is no data for the pathogen population biology in the state.

Genetic Diversity Analysis of Rice Germplasm in Tripura State of Northeast India Using Drought and Blast Linked Markers

open access: yesRice Science, 2017
We genotyped 74 rice germplasms including Tripura's local landraces, improved varieties, cultivars and breeding lines and other rice varieties using molecular markers for genetic diversity, drought QTLs, and blast resistance genes.

Combining High Yields and Blast Resistance in Rice (Oryza spp.): A Screening under Upland and Lowland Conditions in Benin [PDF]

open access: yes, 2018
The future security of the supply of rice for food in Africa depends on improving the level of local production to achieve self-sufficiency. In order to cope with the existing gap between production and actual demand, combining a high level of rice blast

Host Specificity Controlled by PWL1 and PWL2 Effector Genes in the Finger Millet Blast Pathogen Magnaporthe oryzae in Eastern Africa

open access: yesMolecular Plant-Microbe Interactions, 2023
Magnaporthe oryzae, a devastating pathogen of finger millet (Eleusine coracana), secretes effector molecules during infection to manipulate host immunity. This study determined the presence of avirulence effector genes PWL1 and PWL2 in 221 Eleusine blast

Rice-Magnaporthe transcriptomics reveals host defense activation induced by red seaweed-biostimulant in rice plants

open access: yesFrontiers in Genetics, 2023
Red seaweed extracts have been shown to trigger the biotic stress tolerance in several crops. However, reports on transcriptional modifications in plants treated with seaweed biostimulant are limited.

Introgression of blast resistance genes into the elite rice variety MR263 through marker-assisted backcrossing [PDF]

open access: yes, 2015
BACKGROUND: Blast caused by the fungus Magnaporthe oryzae is a significant disease threat to rice across the world and is especially prevalent in Malaysia. An elite, early-maturing, high-yielding Malaysian rice variety, MR263, is susceptible to blast and
