Saccharomyces cerevisiae contains two SNAP25 paralogues, Sec9 and Spo20, which mediate vesicle fusion at the plasma membrane and the prospore membrane, respectively. Fusion at the prospore membrane is sensitive to perturbation of the central ionic layer of the SNARE complex. Mutation of the central glutamine of the t-SNARE Sso1 impaired sporulation, but does not affect vegetative growth. Suppre...

The study investigates the vulnerability of vegetation over Africa to El-Niño Southern Oscillation (ENSO) events using the moving window statistical correlation analysis technique. The correlation analysis was done betweenNormalized Difference Vegetation Index (NDVI) data fromAdvanced VeryHigh Resolution Radiometer (AVHRR) and an ENSO index, namely Multivariate ENSO Index (MEI). The study devel...

the aim followed in this research was to determine the effect of benzyladenin and storage conditions on bulbil formation, germination percentage and growth in iranian tareh (allium ampeloprasum ssp.persicum). immature inflorecences were treated with different concentrations (0,10,50 and 100 ppm) of ba to form bulbils. the experiment was done in rcbd with three replications in esfahan center for...

Studies of the effect of bacteria on neoplasms are among the oldest approaches to the problem of cancer therapy. In 1868, Busch (2) reported tem porary clinical improvement in two patients with sarcoma who developed concurrent erysipelas. Subsequent studies, identifying streptococci and other micro-organisms involved in tumor destruc tion, ascribed their effect to a toxic bacterial prod uct (3)...

Foot-and-mouth disease (FMD) is a major infectious disease in livestock. The common clinical signs in cattle include epidermal vesicles that are majorly distributed around oronasal cavity, feet and teats. The aim of this report is to document an uncommon clinical form of the disease which comprises the occurrence of classic vesicular lesion in a rarely observed location of the horn vegetative t...
