Improved Access to Foreign Markets Raises Plant-Level Productivity... for Some Plants
, 2007
"... ABSTRACT: We weigh into the debate about whether rising productivity is ever a consequence rather than a cause of exporting. Exporting and investing to raise productivity are complimentary activities. For lower-productivity firms, incurring the fixed costs of such investments is justifiable only if ..."

this econometrically using a heterogeneous response model. Unique ‘plant-specific ’ tariff cuts serve as our instrument for the decision of Canadian plants to start exporting to the United States. We find that those lower-productivity Canadian plants that were induced by the tariff cuts to start exporting (a
Posttranscriptional induction of two Cu/Zn superoxide dismutase genes in Arabidopsis is mediated by downregulation of miR398 and important for oxidative stress tolerance
, 2006

Increasing evidence points to a potential role of miRNAs in diverse physiological processes. miR398 targets two closely related C ..."

Determining the ultimate fitness consequences of plant defense traits bears directly on the long-standing view of plant parasites as selective agents and plants as ..."

as active participants in the evolutionary process (1). Induced plant responses to herbivory provided high levels of plant defense that were reflected in increased plant performance. Leaf damage controls had lower fitness than overall controls, indicating that early season herbivory was costly
Increase in ascorbate-glutathione metabolism as local and precocious systemic responses induced by cadmium in durum wheat plants. Plant Cell Physiol
, 2008
"... grown in the presence of cadmium (0–40kM) and analysed after 3 and 7 d for their growth, oxidative stress markers, phytochelatins, and enzymes and metabolites of the ascorbate (ASC)–glutathione (GSH) cycle. Cd exposure produced a dose-dependent inhibition of growth in both roots and leaves. Lipid pe ..."

peroxidation, protein oxidation and the decrease in the ascorbate redox state indicate the presence of oxidative stress in the roots, where H2O2 overproduction and phytochelatin synthesis also occurred. The activity of the ASC–GSH cycle enzymes significantly increased in roots. Consistently, a dose
Arabidopsis mutants selected for resistance to the phytotoxin coronatine are male Sterile, insensitive to methyl jasmonate, and resistant to a bacterial pathogen. Plant Cell 6: 751–759
, 1994
"... The phytotoxin coronatine and the plant growth regulator methyl jasmonate (MeJA) caused similar growth-inhibitory effects on Arabidopsis seedlings. To test whether these two compounds have similar action, 14 independent coil (coronatine-lnsensitive) mutants of Arabidopsis were selected. The mutants ..."

"... Invertase plays multiple pivotal roles in plant development. Thus, its activity must be tightly regulated in vivo. Emerging evidence suggests that a group of small proteins that inhibit invertase activity in vitro appears to exist in a wide variety of plants. However, little is known regarding their ..."

This assertion is based on (1) coexpression of INVINH1 and a fruit
MicroRNA directs mRNA cleavage of the transcription factor NAC1 to downregulate auxin signals for Arabidopsis lateral root development. Plant Cell 17:1376–1386
, 2005
"... Although several plant microRNAs (miRNAs) have been shown to play a role in plant development, no phenotype has yet been associated with a reduction or loss of expression of any plant miRNA. Arabidopsis thaliana miR164 was predicted to target five NAM/ATAF/CUC (NAC) domain–encoding mRNAs, including ..."

, Arabidopsis mir164a and mir164b mutant plants expressed less miR164 and more NAC1 mRNA and produced more lateral roots. These mutant phenotypes can be complemented by expression of the appropriate MIR164a and MIR164b genomic sequences. By contrast, inducible expression of miR164 in wild-type plants led

Increased production of IAA by Rhizoctonia solani is induced by culture filtrate from rice suspension cultures. Plant Cell Physiol
, 1998

To investigate the role of the plant hormones produc-ed by fungi, we tried to construct a system to examine the interaction between Rhizoctonia solani Kiihn MAFF305219 and rice cells in suspension culture (Oc). R. solani was previ-ously found to produce IAA, with the main biosynthetic pathway via th ..."
