      The biochemical lesion that causes impaired chloroplast metabolism (and, hence, photosynthetic capacity) in plants exposed to water deficits is still a subject of controversy. In this study we used tobacco (Nicotiana tabacum L.) transformed with “antisense” ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) DNA sequences to evaluate whether Rubisco or some other Cited by: Four different alpine meadow communities were studied to examine the effects of plant-soil-enzyme interactions on plant composition and diversity. Enzyme activities differed by meadow type, and in general were higher in the upper soil layers (0–10 and 10–20 cm) than in the 20–40 cm layer. Community differences in plant composition or functional group composition were reflected in plant Cited by: 6.

    Agropyron smithii was dominant within the study area and is an important forage species throughout the northern Great Plains. MATERIALS AND METHODS Twelve western wheatgrass (Agropyron smithii) plants, with an equal number of fully expanded leaves, were chosen on the Control and High S02 treatment plots for labeling with lttC   Quantifying these effects is necessary to develop management strategies against herbicide‐resistant weeds. We assessed the pleiotropic effects associated with three mutant alleles of the herbicide target enzyme acetyl‐coenzyme A carboxylase (ACCase) on plant growth and seed production in black‐grass Alopecurus myosuroides. 2Cited by:

Agropyron smithii (a C 3 species) and Bouteloua gracilis (a C 4 species) occur in the same habitat of the shortgrass prairie ecosystem in northeastern Colorado. The hypothesis tested in this study was that the two species differ in their fundamental niches partly as a function of their different physiological responses to temperature and moisture by: Abstract.

Protoplasts and intact chloroplasts isolated from Agropyron smithii Rybd. were utilized in an effort to determine the limiting factor(s) for photosynthesis at supraoptimal temperatures.

Saturated CO 2-dependent O 2 evolution had a temperature optimum of 35°C for both protoplasts and intact chloroplasts. A sharp decline in activity was observed as assay temperature was increased Cited by: 7.

C and N released in root exudates throughout a growing season were estimated in Bouteloua gracilis and Agropyron smithii (dominant species in the shor Cited by: The mechanisms controlling the photosynthetic performance of C 4 plants at low temperature were investigated using ecotypes of Bouteloua gracilis Lag.

from high ( m) and low ( m) elevation sites in the Rocky Mountains of Colorado. Plants were grown in controlled‐environment cabinets at a photon flux density of μmol m −2 s −1 and day/night temperatures of 26/16 °C or 14/7 °C.

Although. Activities of some enzymes related to carbon metabolism were studied in different ecotypes of Rumex nepalensis growing at 12and 3 m above mean sea level.

It is known that different processes relating to photosynthesis, such as photochemistry, carboxylation or oxygenation by ribulose 1,5-bisphosphate carboxylase-oxygenase (and hence photorespiration), carbohydrate synthesis and export, dark respiration and growth have intrinsically different temperature sensitivities in by: Bouteloua gracilis: Blue grama: Poaceae.

Grass. Sheath and leaf blades sometimes glabrous (no hairs) but may also be hairy. Tuft of hair at ligule area. Leaves are smooth, very narrow, wispy, and often senesced at the tips.

This is a short. Increasing pretreatment day temperatures of 20, 30, and 40 C resulted in decreased net photosynthesis in Agropyron smithii (C3) while in Bouteloua gracilis (C4) net photosynthesis was increased.

Effects of metabolite binding to ribulosebisphosphate carboxylase on the activity of the Calvin photosynthesis cycle Gosta PETTERSSON and Ulf RY DE-PETTERSSON Avdelningen for Biokemi, Keniicentrum, Lunds Universitet, Lund (Received ) - EJB 88 by: Photosynthesis, the process by which plants create their food, can be affected by changes in pH within the leaves.

PH is the measure of the acidity of a solution, and it can have a large effect on many biological processes. The pH scale ranges from 0 to 14, with 7 being neutral.

Measurements below 7 indicate acidity, and measurements above 7. 1. The effect of preincubation of extracts of lactating rat mammary gland with ATP, Mg2+ and micromolar concentrations of Ca2+ on the activity of acetyl-CoA carboxylase was studied. Both Mg2+ and Ca2+ activated the enzyme.

The presence and the absence of a prokaryote type and a eukaryote type of acetyl-CoA carboxylase (EC ; ACCase) were examined in members of 28 plant families by two distinct methods: the detection of biotinylated subunits of ACCase with a streptavidin probe, and the detection of the accD gene, which encodes a subunit of the prokaryotic ACCase, by Southern Cited by:   The role of the FMO-like enzymes was discovered when the scientists created a mutant form of the plant Arabidopsis that had growth characteristics indicative of auxin overproduction.

Arabidopsis, a small flowering plant that is a relative of the mustard plant, is the basic model organism used in plant biology research.

Plantlets of Poa alpina L. taken from a single viviparous mother plant in August were pot‐grown in an experimental garden in Abisko, Swedish Lapland. Half of the pots were infected with the annual hemiparasitic angiosperm Rhinanthus minor L. A proportion of the plants were harvested in August the infected grasses were less than half the mass of uninfected controls and had a higher Cited by: one of the abiotic stresses that affect plant growth, physiological activities and developmental processes.

The effect of salinity on growth, protein content and antioxidant enzymes was studied in three kodomillet germplasms (ICIC and IPS ). Seedlings were subjected to. Developmental patterns of glyoxylate cycle and photosynthetic activities have been correlated with electrophoretic profiles of cotyledonary RNA and protein in both light- and dark-grown cucumber seedlings (Cucumis sativus L.) Cytoplasmic rRNA increases fold between days 0 and 5, and the steepest increase coincides with the most rapid rise in activities of the glyoxysomal enzymes Cited by:
