Jasmonate (JA) is an important plant stress hormone that induces various plant defense responses, including the biosynthesis of protective secondary metabolites. The induction of the secondary metabolite biosynthetic gene Strictosidine synthase (Str) in Catharanthus roseus (periwinkle) cells by elicitor requires JA as a second messenger. A 42 bp region in the Str promoter is both necessary and ...
The early secretory antigenic target (ESAT)-6 purified protein and peptides from Mycobacterium tuberculosis were evaluated as antigens for the immunodiagnosis of tuberculosis (TB). Because the control of TB requires improved diagnostic procedures, efforts have increased to identify Mycobacterium tuberculosis-specific epitopes for the immunodiagnosis of active TB and to discriminate between acti...
Human lymphocytes were stimulated in vitro by phytohemagglutinin, concanavalin A, pokeweed mitogen, purified protein derivative-tuberculin, and allogenic cells. The deoxyribonucleic acid synthesis of the lymphocytes was inhibited in increasing degree by 4 to 8 mug of amphotericin B per ml of culture irrespective of lymphocyte stimulant used. The effect of clotrimazole on the deoxyribonucleic ac...
Biologically active (14)C-labeled purified protein derivative ((14)C-PPD) has been prepared from the culture filtrates of seven species of mycobacteria, namely Mycobacterium tuberculosis Johnston strain (PPD), M. bovis BCG (PPD-BCG), M. avium (PPD-A), M. kansasii (PPD-Y), M. intracellulare (PPD-B), M. scrofulaceum (PPD-G), and M. fortuitum (PPD-F). These mycobacteria were grown in a culture med...
