Engineering drought -resistant crop plants is a critically important objective. Overexpression of the vacuolar H ؉ -pyrophosphatase (H ؉ -PPase) AVP1 in the model plant Arabidopsis thaliana results in enhanced performance under soil water deficits. Recent work demonstrates that AVP1 plays an important role in root development through the facilitation of auxin fluxes. With the objective of improving crop performance, we expressed AVP1 in a commercial cultivar of tomato. This approach resulted in (i) greater pyrophosphate-driven cation transport into root vacuolar fractions, (ii) increased root biomass, and (iii) enhanced recovery of plants from an episode of soil water deficit stress. More robust root systems allowed transgenic tomato plants to take up greater amounts of water during the imposed water deficit stress, resulting in a more favorable plant water status and less injury. This study documents a general strategy for improving drought resistance of crops.root development ͉ biotechnology ͉ water deficit stress ͉ tomato

“…DREB2-like genes, belong to the A-2 subgroup, are mainly involved in regulation of genes responsive to osmotic stress (Sakuma et al 2002;Nakashima and Yamaguchi-Shinozaki 2006). Arabidopsis homologs of DREB1/CBF genes have been isolated and characterised in evolutionarily diverse plants with different levels of adaptation to cold stress such as, common wheat (Triticum aestivum L.), rice (Oryza sativa L.), rye (Secale cereale L.), maize (Zea mays L.), canola (Brassica napus), etc., and overexpression of DREB1/CBF genes in transgenic plants increases tolerance to drought, high salt, and freezing stresses (Dubouzet et al 2003;Shen et al 2003;Qin et al 2004;Zhang et al 2004a;Hong and Kim 2005;Benedict et al 2006;Zhao et al 2006;Chinnusamy et al 2010). So, CBF genes may be useful for improving the stress tolerance of crops (Yamaguchi- .…”

The dehydration-responsive element-binding (DREB) protein/C-Repeat Binding Factors (CBFs) belongs to APETALA2 (AP2) family transcription factors that binds to DRE/CRT cis-element in cold-responsive (COR) genes and induce COR genes. CBFs have been isolated and characterized from evolutionarily diverse plant species. CBF pathway is conserved by CBF regulon and the size or the number and kind of target genes vary among freezing sensitive and tolerant plants. Hence, cloning of CBFs from highly freezing tolerant plants such as Lepidium latifolium L. will be useful in understanding the freezing tolerance of this species. In this study, LlCBF, a CBF1 family gene from L. Latifolium L., was cloned using RT-PCR and RACE-PCR. The full length mRNA of LlCBF is 948 bp with an open reading frame of 642 bp, encoding a protein of 213 amino acids with a molecular weight of 23.92 kDa and a theoretical isoelectric point of 4.80. Amino acid sequence analysis showed that LlCBF has an AP2 DNA binding domain, a potential CBF type nuclear localization signal (NLS) and C-terminal acidic domain. Semi-quantitative RT-PCR analysis of LlCBF revealed that this gene is up-regulated by high salt, dehydration and low temperature stresses. The investigation is therefore successful in cloning of a gene having strong homology with CBF transcription factors and responsive to low temperature, high salt and dehydration conditions.

“…Thus, dehydration is a large component of freezing stress. This explains the overlapping relationship between CA and dehydration (drought) responses both in terms of the biochemical changes and in transcriptional regulation (4,5), and evidence indicates that multiple signaling pathways are involved in these responses (6,7).…”
