Brassica juncea BjCHI1 is a plant chitinase with two chitin-binding domains. Its expression, induced in response to wounding, methyl jasmonate treatment, Aspergillus niger infection, and caterpillar Pieris rapae feeding, suggests that it plays a role in defence. In this study, to investigate the potential of using BjCHI1 in agriculture, Pichia-expressed BjCHI1 and its deletion derivatives that ...

Hypoxylonol C (1), isolated from the inedible mushroom Hypoxylon truncatum, exhibited inhibitory activities against the migration and tube formation of HUVECs. A cDNA microarray analysis was performed to investigate the target of hypoxylonol C (1) in HUVECs, and it was found that the genes related to cell cycle and adhesion were down-regulated. The down-regulation of mRNA levels of cell cycle a...

BACKGROUND Rickettsioses are one of the most important causes of systemic febrile illness among travelers from developed countries, but little is known about their incidence in indigenous populations, especially in West Africa. METHODOLOGY/PRINCIPAL FINDINGS Overall seroprevalence evaluated by immunofluorescence using six rickettsial antigens (spotted fever and typhus group) in rural populati...

Original meiotic or both and mitotic chromosome numbers are reported for ten endemic one non species in nine vascular plant families from Iran. The of Acantholimon schahrudicum, A. truncatum, Anthochlamys multinervis, Campanula perpusilla, Cousinia calcitrapa var. interrupta, Dorema ammoniacum, Euphorbia gedrosiaca, Hyocyamus orthocarpus were determined the first time. counts Astrodaucus persic...

Serum samples collected in a cross-sectional survey of grazing cattle on Manyara Ranch, Monduli district, Tanzania, were tested by indirect major antigenic protein 1 fragment B (MAP 1-B) ELISA to determine the seroprevalence of Ehrlichia ruminantium and to assess ranch-level risk factors for heartwater. Heartwater-exposed cattle were widespread on the ranch and overall seroprevalence was 50.3% ...
