Analysis of histones from the yeast Saccharomyces carlsbergensis
Basic chromosomal proteins were isolated from the chromatin of the yeast Saccharomyces carlsbergensis by extraction with H2SO4 and were purified by ion-exchange chromatography. Electrophoresis of the purified fraction on ...
Effects of root-infecting fungi on wheat transport processes and growth
Aurtobasidium bolleyi and Gaeumannomyces graminis damaged transport processes and decreased shoot growth of sand-grown wheat plants only if they colonized the stele and disrupted the phloem of most roots. One week after ...
Ribonucleic acid synthesis by chromatin isolated from Phaseolus aureus Roxb. : The effect of endogenous ribonuclease
Chromatin was isolated from the hypocotyls of Phaseolus aureus Roxb. and assayed for endogenous RNA polymerase (EC 188.8.131.52) activity in vitro. The molecular size of the RNA product, measured by polyacrylamide gel ...
The infection of cucumber mesophyll protoplasts with tobacco mosaic virus
Protoplasts from the first leaf mesophyll of cucumber plants were isolated by an 18 hour combined petinase/cellulase treatment. Conditions favouring the infection of these protoplasts with tobacco mosaic virus (TMV), and ...
Preliminary studies on the RNA components of three strains of cucumber mosaic virus
In investigations of the causal relationships between disease symptoms and virus infection of plants, three strains of cucumber mosaic virus (viz. N, Price's No. 6 and W) which caused different symptoms in several plant ...
Ribosomal RNA metabolism in cucumber leaf mesophyll protoplasts
Aspects of the metabolism of RNA have been studied in enzymatically isolated protoplasts from cotyledon and first leaf mesophyll tissue of two cultivars of cucumber. The first leaf mesophyll protoplasts incorporated ( ...
