Sheath blight disease of rice (Oryza sativa L.) - An overview

Abstract: in the world. Global r ice production was approximately 645 million t in 2007. Rice is being cultivated in 114 countries throughout the world, and more than 50 countries have a minimum annual production of 100,000 t. The majority of the rice (90%) is being produced in Asian countries with China and India being the major producers (IRRI, 2008). The other major rice producing countries are Indonesia, Bangladesh, Vietnam, Thailand, Myanmar, Philippines, Brazil, and Japan. In the United States, rice has been produced for 300 years and currently has an annual production of 230,808 (1000 cwt) t. Major rice producing states of the US include Arkansas, California, Louisiana, Mississippi, Missouri, and Texas.

Colletotrichum gloeosporioides: An anthracnose causing pathogen of fruits and vegetables

Abstract: Colletotrichum species are present in both tropical and subtropical regions of the world. But Colletotrichum gloeosporioides is most important pathogen and belongs to order melanconiales. The complete genome of this pathogen is not yet sequenced but various genes are identified which involved in pathogenesis and host defense. The optimum temperature for growth of this pathogen is 25-28°C, and pH 5.8-6.5. It is usually inactive in dry season but during favorable conditions it causes anthracnose disease to large number of economic crops amongst which mango anthracnose is important as far as losses caused by pathogen is concerned. First of all pathogen establish interaction with host by producing melanized appressorium and then penetrate the host cuticle. After penetration, infection vesicles and primary hyphae are formed. Later, secondary hyphae developed and spread to kill the host cell. Colletotrichum gloeosporioides follows the hemibiotrophic mode of infection where, biotrophic and necrotrophic phases are sequentially occur. The pathogen produced lesions on leaves, fruit and other parts of plant. Finally these lesions become dark and form concentric ring pattern. Colletotrichum gloeosporioides is also known to infect humans but only few incidents of such infections are known. A number of fungal genes have been identified using mutant screen, which plays role in different stages of infection and can be used as potential targets to devise strategies for controlling anthracnose disease in fields. This review focuses on up to date knowledge of all aspects of C. gloeosporioides biology.

Physicochemical Characterization of Opuntia ficus-indica Seed Oil from Morocco

Abstract: Oil yield, physicochemical, tricylglecrols, fatty acid composition, sterols, tocopherols and stability oxidative of Opuntia ficus-indica seed oil obtained by cold pressing extraction were determined. Oil yield was between 6 - 7%. Nine triacylglycerols were identified, the major being LLL (24.94%), LLO (21.31%), LLP (15.90%), and OOL (13.76%). The main fatty acids ranked in the following order of abundance: C18:2 (60.8%), C18:1 (21.3%),C16:0 (11.9%), C18:0 3.4%). The quality and composition of some minor constituents of seed oil were determined. Total tocopherol content in seed oil was 94.6 mg/100 g, γ-tocopherol (90%) was the main constituent. the sterol composition is similar to that of other vegetable oils, level of sterols making up 90.33 mg/100g seed oil was present. The sterol marker, β-sitosterol, accounted for 75.3% of the total sterol content in the seed oil. This oil presented a moderate content in phospholipids.

Epidemiology of Female Infertility; A Review of Literature

Abstract: The prevalence of infertility is varies worldwide ranging from 3 to 7. The consequences of infertility are societal repercussions, personal suffering, psychological effects, clinical depression and sexual dysfunction. Therefore, the aim of the present study was a systematic review of the literature to determine the main risk factors of female infertility. MEDLINE, EMBASE and Cochrane Database were searched from 1980-2013. Information about study objectives, participants and type of study were searched systematically with extensive key words to optimize the sensitivity of data collection. Eighty-two published articles were included in the overall review. Ovarian factors, tubal and peritoneal factors, anomalies, advanced ages (over 35 years), hormonal disorders, habits, genetic factors, medical conditions and life style are the main causes of infertility in women. Changes of lifestyle, identifying and controlling chronic diseases, rapid and suitable treatments for sexually transmitted diseases can increase the chance of women fertility process.
