“…As expected, because of the use of a stress-inducible promoter, no significant difference in the concentration of any analysed metabolite was observed between wt and pCOR15a-Myb4 plants under control conditions. However, under water deficit conditions, the concentration of these compounds was found to be significantly higher in pCOR15a-Myb4 transgenic lines than in wt and to be comparable to that found in pCaMV35S-Myb4 transgenic plants (Vannini et al, 2007). Dai et al (2010b) have performed a systematic characterisation of the metabolic changes induced by water depletion in the roots of the medicinal plant, Salvia miltiorrhiza Bunge, comparing the results obtained using two metabolite analysis techniques ( 1 H-NMR and LC-DAD-MS) and four extraction methods based on different solvents (see also section 2.2).…”

“…Similarly, Hierarchical Clustering Analysis (HCA) revealed a strong influence of the genotype and a lower influence of the environment on the metabolic profiles (Semel et al, 2007). Vannini et al (2007) analysed the drought-tolerant phenotype and targeted metabolite accumulation in wt and transgenic tomato plants overexpressing the rice Osmyb4 gene either under a constitutive (pCaMV35S) or a stress-inducible (pCOR15a) promoter. They found that the ameliorated tolerance of the transgenic lines was associated with a higher accumulation of sugars (sucrose, fructose and glucose) and proline (measured as percentage of total amino acid content).…”

“…Myb tfs interact with ciselements in the promoter regions of several stress-related genes through ABA-dependent pathway of stress signalling for the upregulation of abiotic stress responsive genes. Overexpression of Myb tf results in improved drought and salt tolerance in Arabidopsis (Ding et al 2009), osmotic tolerance (Abe et al 2003), drought stress in tomato (Vannini et al 2007) and drought and cold tolerance in the apple transgenic plants (Pasquali et al 2008). Overexpression of a StMYB1R-1 transgene in potato plants improved tolerance to drought stress while not influencing significant effects on other agronomical traits (Shin et al 2011).…”

In order to meet the ever rising global demand for natural rubber, cultivation of Hevea is being extended to nontraditional regions of India where extreme climatic conditions like drought and low temperature negatively influence the crop performance. In order to ensure maximum productivity, identification of drought tolerant clones of Hevea which can cope up with stress and give better crop yield is essential. Several attempts have been made previously to identify genes that are associated with drought tolerance in Hevea. In the present study, quantitative expression analysis was made using quantitative PCR for seven drought associated transcripts in four clones of Hevea with varying levels of drought tolerance. Among the seven genes studied, Mitogen Activated Protein (MAP) kinase, Myeloblastosis (Myb) transcription factor, C-repeat responsive element/Dehydration Responsive Element (CRT/DRE) binding factor and Nuclear Factor Y subunit A (NFYA) showed a positive association with drought tolerance. Transcripts of ascorbate peroxidase and heat shock protein 70 (HSP 70) did not show any correlation with drought tolerance. Interestingly, catalase gene was found down regulated in all the clones under drought condition. The possible role of these genes based on their level of gene expression in four different clones of Hevea with varying levels of drought tolerance is discussed.

“…Arabidopsis transgenic plants overexpressing OsMYB4 showed increased chilling and freezing tolerance with a dwarf phenotype (Vannini et al, 2004), the tomato transgenic showed higher tolerance to drought stress (Vannini et al, 2007), whereas increased drought and cold tolerance was observed in the apple transgenic (Pasquali et al, 2008). Overexpression of a StMYB1R-1 transgene in potato plants improved plant tolerance to drought stress while having no significant effects on other agricultural traits (Shin et al 2011).…”
