Brown Spot Resistance in Rice : A Review
Authors(7) :-Ali Sattari, H Nohtani, Na Azhdarpoor, M Ghadami, MO Madahinasab, K Moradi, Mo Noorozi Rice is suffering from several fungal diseases among them brown spot caused by Bipolaris oryzae is important. Rice brown spot (BS) is a chronic disease that affects millions of hectares of rice. Chaetomium cochliodes proved to be a new antagonistic fungus against brown leaf spot of rice. BS is by far one the strongest yield reducers amongst rice diseases today. Analysis of brown-spot infected control plants suggested that C.miyabeanus represses plant photosynthetic processes and nitrate reduction in order to trigger premature senescence and cause disease. Biological products formulated from Ch cochliodes were tested to control brown leaf spot of rice. Host plant resistance to disease is an effective and economical way to manage BS. Spot formation has been analyzed mainly using mutants. Many mutants exhibiting spontaneous cell death have been reported in various plants, including Arabidopsis, maize, barley, and rice.Three rice genes, Spl7, Spl11, and Spl18, have been cloned and characterized. BS is conventionally perceived as a secondary problem that reflects rice crops that experience physiological stresses, e.g. drought and poor soil fertility, rather than a true infectious disease.
