Rust Infection of Black Poplar Trees Reduces Photosynthesis but Does Not Affect Isoprene Biosynthesis or Emission

Frontiers in Plant Science, 2018
Poplar (Populus spp.) trees are widely distributed and play an important role in ecological communities and in forestry. Moreover, by releasing high amounts of isoprene, these trees impact global atmospheric chemistry.

Investigation into the role of volatile organic compounds, and abscisic in stomatal regulation, in the resurrection plant Xerophyta humilis

, 2011
The findings presented in this study give evidence for an ABA-mediated stomatal closure in response to initial dehydration of X. humilis, however, from 60% RWC onwards, stomata were observed to open again. This supplies further support for the hypothesis

Precise precursor rebalancing for isoprenoids production by fine control of gapA expression in Escherichia coli

, 2018
Biosynthesis of isoprenoids via the 1-deoxy-D-xylulose-5-phosphate (DXP) pathway requires equimolar glyceraldehyde 3-phosphate and pyruvate to divert carbon flux toward the products of interest. Here, we demonstrate that precursor balancing is one of the

Concurrent Measurement of O2 Production and Isoprene Emission During Photosynthesis: Pros, Cons and Metabolic Implications of Responses to Light, CO2 and Temperature

Plant, Cell &Environment, EarlyView.
ABSTRACT Traditional leaf gas exchange experiments have focused on net CO2 exchange (Anet). Here, using California poplar (Populus trichocarpa), we coupled measurements of net oxygen production (NOP), isoprene emissions and δ18O in O2 to traditional CO2/H2O gas exchange with chlorophyll fluorescence, and measured light, CO2 and temperature response ...

Membrane Engineering for Carotenoid Production in Escherichia coli

SynBio
Carotenoids are a class of highly hydrophobic compounds synthesized by plants in limited quantities. This study explores the potential for increasing the production yield of lycopene, a typical carotenoid compound, through engineered Escherichia coli ...

Diurnal Variations in Photochemical Energy Utilization and Osmotic Adjustments in Black Poplar Leaves Under Progressive Water Stress

Plant, Cell &Environment, EarlyView.
ABSTRACT Drought limits the productivity of fast‐growing woody crops, although the metabolic adjustments conferring water stress tolerance remain poorly understood. We investigated the responses of Populus nigra seedlings to water stress by integrating daily physiological measurements and NMR metabolomic analyses.

Isoprenoids Are Essential for Fruiting Body Formation in Myxococcus xanthus

, 2009
It was recently shown that Myxococcus xanthus harbors an alternative and reversible biosynthetic pathway to isovaleryl coenzyme A (CoA) branching from 3-hydroxy-3-methylglutaryl-CoA.

Nor-isoprenoids profile during port wine ageing—influence of some technological parameters [PDF]

, 2004
Nor-isoprenoid compounds, such as β-damascenone, β-ionone, 2,2,6-trimethylcyclohexanone (TCH), 1,1,6-trimethyl-1,2-dihydronaphthalene (TDN) and vitispirane were determined in 14 young port wines and 45 old port wines.
