Abiotic stresses have negative effects on potato growth and production. To enhance the abiotic stress tolerance of the commercial potato cultivar, Desiree, rd29A::AtDREB1A transgenic lines have been developed. The salinity and freeze tolerance of these transgenic lines has previously been demonstrated; however, their dehydration tolerance remains to be elucidated. First of all, we have tackled ...

Plants have evolved different strategies to resist drought, of which the best understood is the abscisic acid (ABA)-induced closure of stomatal pores to reduce water loss by transpiration. The availability of useful promoters that allow for precise spatial and temporal control of gene expression in stomata is essential both for investigating stomatal regulation in model systems and for biotechn...

The Arabidopsis mutation, los2, impairs cold-responsive gene transcription, acquired freezing tolerance and plant resistance to chilling under certain conditions. LOS2 was isolated through positional cloning and shown to encode an enolase in the glycolytic pathway. In animal cells, enolase has also been known to function as a transcription factor that represses the expression of c-myc by bindin...

DNA binding with One Finger (DOF) transcription factors are involved in multiple aspects of plant growth and development but their precise roles in abiotic stress tolerance are largely unknown. Here we report a group of five tomato DOF genes, homologous to Arabidopsis Cycling DOF Factors (CDFs), that function as transcriptional regulators involved in responses to drought and salt stress and flo...

Drought stress can trigger the production of ABA in plants, in response to adverse conditions, which induces the transcript of stress-related marker genes. The R2R3 MYB TFs are implicated in regulation of various plants developmental, metabolic and multiple environmental stress responses. Here, a R2R3-MYB cloned gene, GaMYB62L, was transformed in Arabidopsis and was functionally characterized. ...

Strictosidine synthase-like (SSL) is a group of gene families in the Arabidopsis genome, which whose orthologues in other plants are key enzymes in mono-terpenoid indole-alkaloid biosynthesis pathway. The SSL7 is upregulated upon treatments of Arabidopsis plants with signaling molecules such as SA, methyl jasmonate and ethylene. To find the functional role of the gene, a T-DNA-mediated knockout...

A gene family called Strictosidine synthase like (SSL) exists in Arabidopsis thaliana genome.  Orthologs gene in Catharanthus roseus is involved in monoterpenoid indole alkaloids biosynthesis. A member of gene family (SSL6) has been induced by various biotic and abiotic stresses. To further analyse of the functional role of the gene in response to salt stress, the SSL6 T-DNA insertion...

An Arabidopsis (Arabidopsis thaliana) multigene family (predicted to be more than 20 members) encodes plant C-terminal domain (CTD) phosphatases that dephosphorylate Ser residues in tandem heptad repeat sequences of the RNA polymerase II C terminus. CTD phosphatase-like (CPL) isoforms 1 and 3 are regulators of osmotic stress and abscisic acid (ABA) signaling. Evidence presented herein indicates...

Guard cells shrink in response to drought and abscisic acid (ABA), which is caused by efflux of ions that in turn reduces stomatal aperture and improves the plant's ability to retain moisture. Cytosolic free calcium is an essential secondary messenger in guard cell ABA signaling, but the details of this regulatory pathway remain sketchy. Here, the calmodulin-like protein CML20, which has four E...

A novel gibberellin (GA)-deficient mutant designated dwarf and delayed-flowering 1 (ddf1) was isolated from a library of activation-tagged Arabidopsis. This mutant showed dwarfism and late-flowering, but the phenotype was rescued by exogenous GA3 like known mutants defective in GA biosynthesis. The contents of bioactive GA4 and GA1 were in fact decreased in ddf1 at least partially through the r...
