To demonstrate the involvement of circadian rhythm in photoperiodic time measurement, photosensitive female blackheaded buntings were kept under different photoperiodic schedules consisting of 6 h of main photophase coupled with scotophases of various durations. Ovarian mass and circulating plasma estradiol concentration were found to be elevated in cycles of 6L:6D, 6L:36D, 6L:54D and in control 15L:9D groups. But cycles of 6L:18D, 6L:42D and 6L:66D did not stimulate ovarian growth or elevate circulating plasma estradiol concentration. These results are consistent with the Bünning hypothesis according to which a photoperiodic response is elicited as a result of the coincidence of light with the photoinducible phase of an endogenous circadian rhythm. The results thus indicate the involvement of a circadian rhythm of photoinducibility in ovarian growth and estradiol secretion. 相似文献

Organogenesis was induced in callus derived from mature zygotic embryos of six families of loblolly pine (Pinus taeda L.) within 24 weeks of culture. Elongation of adventitious buds was achieved on TE medium supplemented with 0.5 mg l−1 indole-3-butyric acid (IBA) and 2 mg l−1 6-benzyladenine (BA). The most suitable medium for root formation proved to be TE medium supplemented with 0.1 mg l−1 IBA, 1 mg l−1 BA, and 0.5 mg l−1 gibberellic acid (GA3). One hundred and sixty-nine regenerated plantlets were transferred to a perlite:peatmoss:vermiculite (1:1:1) soil mixture,
and 98 plantlets survived in the field.

We report evidence that a monoclonal antibody raised by immunization with a vasoactive intestinal peptide (VIP)-carrier protein conjugate selectively hydrolyzes VIP and a fluorescence quenched decapeptide (FQ14-22D), representing the region of VIP most susceptible to autoantibody-mediated cleavage (residues 14-22). A high affinity of the antibody for VIP and a lower affinity for FQ14-22D were revealed by kinetic studies and further substantiated by potent inhibition of FQ14-22D cleaving activity by full-length VIP. Sequencing of FQ14-22D hydrolysis products indicated selective cleavage at one peptide bond. These observations suggest that antibodies induced against naturally occurring polypeptide antigens can express peptidolytic activity targeted for specific sequences in the recognition epitope. 相似文献

Summary Seven isolates belonged toA. brasilense and 3 belonged toA. lipoferum. Isolates having more denitrifying capacity fixed less nitrogen in nitrogen free semi-solid malate medium. One strain ofA. lipoferum having high nitrogen fixing capacity with negative test for denitrification was tested as inoculant to supplement the nitrogen
need of a wheat crop in field condition with different doses of N with and without the inoculant. While control without nitrogen
yielded 1260 kg/ha the yield in inoculated treatment was 2070 kg/ha resulting in significant increase. In a treatment receiving
40 kg N/ha the grain yield was 2370 kg/ha as against yield of 3110 kg/ha in a similar treatment receiving fertiliser plus
inoculant. Thus increase in yield was about 30%. Further the treatment receiving 80 kg N/ha yielded 2970 kg/ha as against
yield of 4150 kg/ha in a treatment receiving inoculant alongwith the above dose of the fertiliser. Thus increase in yield
due to application of inoculant was about 36%. Similarly, the uptake of N in different treatments was augmented due to inoculation
of seeds with the culture. 相似文献
