Identification of Cytokinins in Root Exudate of the Rice Plant 总被引:4,自引:0,他引:4

Cytokinins, cis-zeatin and cis- and (trans-ribosylzeatin, wereidentified in the root exudate of the rice plant (Oryza sativa,indica cultivar IR-24) after several chromatographic separationsand combined gas-liquid chromatography-selected ion monitoring(GC-SIM) analysis. The presence of trans-zeatin ribotide wassuggested by enzyme hydrolysis, subsequent chromatographic separationand GC-SIM. The comparatively high content of the ribotide inthe root exudate suggests the form of cytokinins to be transportedfrom roots to other parts in the rice plant.

Responses of leukocyte, blood glucose and coagulation system in calves were investigated to injection with Escherichia coli endotoxin. Severe leukopenia and hyperglycemia following transient hypoglycemia were noted within 24 hours after injection. In the coagulation system, a definite decrease in platelet count, prolongation of prothrombin time and activated partial thromboplastin time were observed. Fibrinogen, soluble fibrin monomer complex and clotting time, however, varied. 相似文献

To study the gene products of the HLA complex, we produced two monoclonal antibodies, termed HU-18 and HU-23. They were active in complement-dependent cytotoxicity and detected B-cell alloantigens encoded by a locus (or loci) linked to HLA. When three types of HLA-DR4 homozygous B-cell lines with different HLA-D specificities were tested for reactivity with HU-18 and HU-23, they displayed distinct reaction patterns depending on the HLA-D specificities they possessed: EBV-Wa (HLA-DYT homozygous), negative for both HU-18 and HU-23; KT2 and KOB (HLA-DKT2 homozygous), positive only for HU-18; and ER (HLA-Dw4 homozygous), positive for both. These differential reaction patterns were further confirmed by testing against a panel of 17 HLA-DR4-positive peripheral blood lymphocytes with known HLA-D specificities. Thus, these monoclonal antibodies allow us to identify HLA-DYT, HLA-DKT2, and HLA-Dw4 solely by serologic methods. This is the first clearcut serologic identification of these three HLA-DR4-associated HLA-D specificities, which have been indistinguishable by conventional serology and identified only by cellular techniques. It is hoped that immunochemical investigations using HU-18 and HU-23 will advance our understanding of the HLA-D region on a molecular level. 相似文献

Molecular chain conformations of poly-γ-methyl-L -glutamate, poly-γ-methyl-D -glutamate, and poly-γ-methyl-D ,L -glutamate in membranes prepared by using mainly trifluoroacetic acid and formic acid as solvents were investigated by infrared, X-ray diffraction, and optical rotatory dispersion measurements. It was pointed that these polymers exist in the α-helix form in membranes cast from trifluoroacetic acid solutions, but in the β-chain form in membrances swollen in formic acid. The β-chain structure was also observed in crystals precipitated from dilute solutions including formic acid. The formation of the β-chain structure was discussed. 相似文献

Brachial plexuses of an adult female capuchin monkey (Cebus capucinus) were observed macroscopically. The main characteristic features of the organization of the plexus were as follows:Substantially the same organization was observed in the plexuses on both sides. The plexuses were formed by the union of the 5th–8th cervical nerves and the 1st thoracic nerve. The component from C5 contributed only to the superior posterior division; consequently the superior trunk in the strict sense was lacking. The medial cord was a peripheral extension of the inferior anterior division and formed a common trunk with the lateral root of the median nerve. Therefore, the medial root of the median nerve in the strict sense was absent, and the median nerve arose from the common trunk with the ulnar nerve. In the plexus on the right side, a long aberrant branch was found, which arose as an extra anterior divison of the middle trunk and joined peripherally the medial cord at a point where the cord formed the common trunk with the lateral root of the median nerve.These findings were compared with previous data obtained from other primates. 相似文献
