Resensitization to gibberellin of grand rapids lettuce seeds treated with continuous far red light
(Journal of the Tennessee Academy of Science, 1973) -
Amino acid biosynthesis in isolated pea chloroplasts: metabolism of labeled aspartate and sulfate
(FEBS Letters, 1978)Accumulating evidence points to chloroplasts as the site of nitrite and sulfate reduction and incorporation into carbon skeletons [I] Furthermore, several enzymes of aspartate-family amino acid biosynthesis recently have ... -
Effects of lysine, threonine, and methionine on light-driven protein synthesis in isolated pea (Pisum sativum L.) chloroplasts
(Planta, 1978)Light-driven incorporation of [14C]leucine (LEU) into protein in isolated pea chloroplasts was inhibited by 0.1 and 1 mM lysine (LYS), 0.1–10 mM threonine (THR) and 1 mM methionine (MET). Equimolar combinations of LYS plus ... -
Itracellular localization of aspartate kinase in spinach (Spinacea oleracea)
(FEBS Letters, 1979)1. Enzyme distribution between chloroplasts and the nonchloroplast parts of green leaf cells of Spinacia oleracea, Nicotiana rustica, Vicia faba, and Phaseolus vulgaris have been investigated by use of the nonaqueous ... -
The isolation of a lysine sensitive aspartate kinase from pea leaves and its involvement in homoserine biosynthesis in isolated chloroplasts
(FEBS Letters, 1979)Homoserine is an intermediate in the biosynthesis of the essential amino acids Thr and Met in microorganisms [I] and higher plants [2]. Pea seedlings synthesise massive amounts of Hse, mainly in the roots [3-51, although ... -
A rapid method for isolation of purified physiologically active chloroplasts, used to study the intracellular distribution of amino acids in pea leaves
(Planta, 1980)A procedure is described for the rapid (<5 min) isolation of purified, physiologically active chloroplasts from Pisum sativum L. Mitochondrial and microbody contamination is substantially reduced and broken chloroplasts ... -
Identification and measurement of homoserine by gas-liquid chromatography
(Analytical Biochemistry, 1980)Homoserine has been analyzed quantitatively by gas-liquid chromatography of its N-heptafluorobutyryl isopropyl ester. The method was confirmed by analysis of the soluble amino acid fraction of pea leaves. The possible use ... -
Photosynthetic formation of the aspartate family of amino acids in isolated chloroplasts
(Plant Physiology, 1980)The metabolism of 14C-labeled aspartic acid, diaminopimelic acid, malic acid and threonine by isolated pea (Pisum sativum L.) chloroplasts was examined. Light enhanced the incorporation of [14C] aspartic acid into soluble ... -
Amino acid biosynthesis in chloroplasts
(Balaban International Science Service, 1981) -
Light-driven DNA biosynthesis in isolated pea chloroplasts
(FEBS Letters, 1983)Isolated chloroplasts from Pisum sativum leaves catalyze [3H]thymidine incorporation into acid-insoluble material using light as the sole energy source. Neither ribonucleotides, deoxyribonucleotides nor deoxyribonucleosides ... -
Studies on the Background Levels of Heavy Metals (Cu,Zn,Pb,Cd,Ni,Hg,Cr,As,Ti) in Soils along Hangzhou Section of the Grand Canal
(Zhejiang Agricultural University Press,, 1984) -
DNA biosynthesis in intact, isolated chloroplasts
(Clarendon Press, 1984) -
ß- alanine metabolism and high salinity stress in the sea anemone, Bunodosoma cavernata
(Journal of Comparative Physiology B, 1984)During high salinity stress, β-alanine accumulates to high levels in the sea anemone,Bunodosoma cavernata. Following a salinity increase from 26‰ to 40‰ β-alanine increased 28-fold from 1.5 to 41.9 μmoles/g dry weight. ... -
Synthesis of aspartate-family amino acids
(CRC Press, 1987) -
DNA biosynthesis in chloroplasts and its regulation: Studies on isolated chloroplasts and chloroplast extracts
(Progress in Photosynthesis Research, 1987)During leaf development, chloroplasts are formed by the binary fission of pre-existing plastids (1); thus, replication of chloroplast DNA (ctDNA) must occur to maintain an adequate amount in each organelle. The levels of ... -
Purification of chloroplasts using silica-sols
(Academic Press, 1987)This chapter describes procedures for the purification of chloroplasts using silica sols. Silica sols have two major advantages as media for density gradients—namely, low viscosity and negligible osmotic potential, allowing ... -
Synthesis of branched chain amino acids
(CRC Press, 1987) -
Starvation-Free Solutions of Mutual Exclusion Problems Using Semaphores
(Proceedings of the ACM South Central Regional Conference, 1987-10)The standard implementation of mutual exclusion by means of a semaphore allows starvation of processes. Between 1979 and 1986, three algorithms were proposed that preclude starvation. These algorithms use a special kind ... -
DNA synthesis in chloroplasts. I. Characterization of and developmental variation in both light- and ATP-driven thymidine incorporation by isolated intact chloroplasts
(Journal of Experimental Botany, 1988)Intact chloroplasts from young pea leaves were able to incorporate [3H]thymidine into DNA at relatively high rates (50 pmol mg-1 chlorophyll h-1 or more), using light as the sole energy source. The intact plastids were ...
