Rice Blast Prevalence in Smallholder Rice Farmlands in Uganda

the stady and analysis of rice agroclimatology in lenjan

the west of esfahan province, iran, is one of the most important agricultural areas throughout the country due to the climate variability and life-giving water of zayanderood river. rice is one of the major and economic crops in this area. the most important climatic elements in agricultural activities which should be considered include temperature, relative humidity, precipitation and wind. so...

Rice blast fungus sequenced

Rice (Oryza sativa L.) is a major staple food crop for half of the world’s population. The International Rice Research Institute, Philippines, estimates that in order to feed the growing global population, rice production must increase by another one-third by the year 2020. Magnaporthe grisea (anamorph, Pyricularia oryzae) causes rice blast disease (Figure 1) and is the most destructive pathoge...

Blast in a Durably Resistant Rice Cultivar

Moroberekan, ajaponica rice cultivar with durable resistance to blast disease in Asia, was crossed to the highly susceptible indica cultivar, C039, and 281 F, recombinant inbred (RI) lines were produced by single seed descent. The population was evaluated for blast resistance in the greenhouse and the field, and was analyzed with 127 restriction fragment length polymorphism (RFLP) markers. Two ...

Characterization of rice mutants with enhanced susceptibility to rice blast.

As a first step towards identifying genes involving in the signal transduction pathways mediating rice blast resistance, we isolated 3 mutants lines that showed enhanced susceptibility to rice blast KJ105 (91-033) from a T-DNA insertion library of the japonica rice cultivar, Hwayeong. Since none of the susceptible phenotypes co-segregated with the T-DNA insertion we adapted a map-based cloning ...
