ii ACKNOWLEDGMENTS I dedicate my work to my parents Mr. Nageswara Rao and Mrs. Vijaya Lakshmi, my brother and sister-in law Mr. Sapta Nag and Mrs. Parimala and my grandparents Mr. Gandhi and Mrs. Sambrajam for their constant support and encouragement throughout my life. I am very grateful to my advisor Dr. A. Srivastava for his guidance, patience and understanding throughout this work. His sugg...

Prp28 (pre-mRNA-splicing ATP-dependent RNA helicase 28) is a spliceosomal DEAD-box helicase which is involved in two steps of spliceosome assembly. It is required for the formation of commitment complex 2 in an ATP-independent manner as well as for the formation of the pre-catalytic spliceosome, which in contrast is ATP-dependent. During the latter step, Prp28 is crucial for the integration of ...

AIMS To examine organic neem compounds for their effective growth inhibition of saprotrophic soft-rot fungi on anthracite bricks bound with collagen and lignin for use in iron foundry cupolas as an alternative fuel source. METHODS AND RESULTS Azadirachtin, crude neem oil (NO), and clarified neem oil extract (CNO) were combined with copper to inhibit the growth of the soft-rot fungus, Chaetomi...

The mean numbers of colony-forming units of molds present on vegetables at the time of harvest were in the range of 4.2 X 10(3) to 6.7 X 10(3)/g for all vegetables except cucurbits and asparagus. The numbers were not influenced by cultivars within species, duration of the growing season, distant separation of the growing fields, or elevation above ground. Numbers increased with rainfall during ...

Four novel compounds, chaephilone C (1), chaetoviridides A-C (2-4), were obtained from the culture of a deep sea derived fungus Chaetomium sp. NA-S01-R1, together with four known compounds-chaetoviridin A (5), chaetoviridine E (6), chaetomugilin D (7) and cochliodone A (8). Their structures, including absolute configurations, were assigned based on NMR, MS and time-dependent density functional ...

Jatropha curcas L., a perennial plant grown in tropics and subtropics is popularly known for its potential as biofuel. The plant is reported to survive under varying environmental conditions having tolerance to stress and an ability to manage pest and diseases. The plant was explored for its endophytic fungi for use in crop protection. Endophytic fungi were isolated from leaf of Jatropha curcas...

Pollen samples collected in the spring of 2002 in 8 south-western Slovakia localities and 40 live individuals of bumblebee were analyzed for the presence of bacteria and microscopic fungi. Microorganisms occurring on pollen and bumblebees were identified using cultivation and microscopic methods supplemented with biochemical tests. In the pollen were found fermenting and non-fermenting Gram-neg...

1. Mutants produced by x-irradiation of fungal spores of Chaetomium globosum have been compared with those produced by ultraviolet irradiation. 2. The most striking difference between the mutants produced by x-irradiation and ultraviolet irradiation is the absence in x-ray experiments of the K mutant which is produced in large numbers at short ultraviolet wave lengths. 3. A comparison is made o...

To the Editor, The Indian Medical Gazette Sir,?In your January 1938 number, Mr. MSyddiq has published a short resume of the life his ^ of the eye-fly, S. funicola. It is however necessary mention that Jepson and Pinto (1927), in the Government Agricultural Service, have studied the life history, and bred the flies artiftci ^ on a variety of dead organic matter: they lived ^ much as six weeks in...
