Abstract In Vitis vinifera L, photosynthesis and photosynthate partitioning are affected in the presence of fludioxonil pyrimethanil, two fungicides commonly used vineyards against Botrytis cinerea Pers. However, effects were found to be different according model studied: plantlets (cv Chardonnay) grown vitro , fruiting cuttings plants (cvs Chardonnay, Pinot noir Meunier). both decreased gas exchanges, photosynthetic pigment starch concentrations leaves, whereas soluble carbohydrates...
The Arabidopsis thaliana sam1 gene encoding S-adenosylmethionine synthetase (EC 2.5.1.6) was transferred to flax (Linum usitatissimum) cells via Agrobacterium tumefaciens. This enzyme catalyses the conversion of methionine (SAM), major methyl group donor in living cells. aim this work study consequences an increased SAM-synthetase (SAM-S) activity transgenic cell lines on both production mono- and dimethoxylated lignin monomers degree methylesterification pectins. Hypocotyls were...
To evaluate the impact of herbicide flumioxazin (fmx) on nontarget grapevines, its effects were assessed fruiting cuttings and field-grown plants. The stress caused by differed according to grapevine model. In cuttings, leaf gas exchange photosynthetic pigment levels as well hexose contents decreased, whereas sucrose starch accumulated, suggesting an inhibition photosynthesis increase carbohydrate reserves a response fmx-induced stress. Paradoxically, in leaves, fmx stimulation...
Phytoremediation of metalloids by conifers is not widely studied although they may be relevant for several contaminated sites, especially those located in cold areas and sometimes under dry climates. Here, seeds Douglas fir were sown greenhouse on three soils collected two French former mines: a gold mine (soils L1 L2) lead silver (soil P). These are highly Pb, As, Sb at different concentrations. Plants harvested after ten weeks. Growth parameters, primary metabolite content, shoot root...
In this work, the capacity of soil-applied herbicide flumioxazin (fmx) to trigger defence mechanisms was assessed using 6-week-old in vitro grown Vitis vinifera L. plantlets. Time-course studies demonstrated that induced expression basic beta-1,3-glucanase (Vvglu), chitinase (Vvchit1b) and PR10 (VvPR10.3) genes encoding three pathogenesis-related (PR) proteins involved grapevine against pathogens. Thus, all transcripts accumulated tissues reach maximum values after 24-72 h exposure, except...
<title>Abstract</title> The accumulation of metal(loid)s in soils, often linked to human activities, is a source toxicity for living organisms. Erosion and leaching from contaminated sites can spread pollution adjacent ecosystems. Phytostabilization method that consists selecting plant species accumulating little or no aerial parts establish vegetation cover thus stabilize the soil. Seeds white lupin, cultivated vetch, buckwheat were sown greenhouse on soils former French mines (Pontgibaud...
