Purification and properties of chloroplast leucyl-tRNA synthetase from a higher plant: Phaseolus vulgaris.
The chloroplast leucyl-tRNA synthetase from Phaseolus vulgaris was purified by ammonium sulfate precipitation and chromatography on DEAE-cellulose, hydroxylapatite, and phosphocellulose. Finally, the pure enzyme was obtained after affinity chromatography on Blue Sepharose CL-6B using specific elution with a pure Escherichia coli tRNALeu isoacceptor. The specific activity of chloroplast leucyl-t...
متن کاملFactors Affecting Root Formation of Phaseolus Vulgaris.
The successful rootingof leafy cuttings inivolves three physiologieally distinct processes: initiation of root primordia; development of true roots from these initials; and mainitenance of the cutting as ani excised organ during the rooting. The first of these, where it does niot take place sponitanieously, cani be brought about in many plants by treatment with auxini. The second (outgrow^th of...
متن کاملControl of Wilt and Root Rot Incidence in Phaseolus Vulgaris L. by Some Plant Volatile Compounds
Essential oils from four plants, i.e. geranium, rosa, lemon and mint were tested for their activity in vitro and in vivo against Rhizoctonia solani and Fusarium oxysporum f. sp. phaseoli, the cause of root rot and wilt of beans. In vitro, they were found to have an inhibitory effect against the mycelial growth of R. solani and F. oxysporum f. sp. phaseoli. Complete inhibition in fungal growth w...
متن کاملNitrogen-15 Dioxide Uptake and Incorporation by Phaseolus vulgaris (L.).
The sorption rate and metabolic fate of nitrogen dioxide, a major air pollutant, have been determined for Phaseolus vulgaris (L.). Sorption was determined kinetically by chemiluminescent monitoring of (15)NO(2) removal from the test atmosphere and directly by mass spectrometric analysis of nitrogen derived from the plant tissue. Sorptive processes were first order with respect to (15)NO(2) conc...
متن کاملRecovering phosphorus from soil: a root solution?
value of the current global soil P resource is appreciating the range of complexed P forms in soil and their specific issues for crop P accessibility. Soil organic P is especially poorly considered in terms of amounts and future utility. Learning to better utilize all of the different residual P forms in soil is essential to providing a sustainable cycle between agricultural inputs and plant up...
