The AmMYB308 and AmMYB330 Transcription Factors from Antirrhinum Regulate Phenylpropanoid and Lignin Biosynthesis in Transgenic Tobacco
It is demonstrated that overexpression of two MYB genes from Antirrhinum represses phenolic acid metabolism and lignin biosynthesis in transgenic tobacco plants.

A role for Myb305‐related proteins is suggested in the activation of phenylpropanoid biosynthetic genes in flowers, consistent with the genetically demonstrated role of plant Myb proteins in the regulation of genes involved in flavonoid synthesis.

Plants contain a number of myb-related transcriptional activators involved in a diversity of gene regulation, including those involved in controlling anthocyanin biosynthesis and carbohydrate secretion.
Expression of the yeast trehalose-6-phosphate synthase gene in transgenic tobacco plants: pleiotropic phenotypes include drought tolerance
These pleiotropic effects, and the fact that water loss from detached leaves was not significantly affected by trehalose accumulation, suggest that synthesis of this sugar, rather than leading to an osmoprotectant effect, had altered sugar metabolism and regulatory pathways affecting plant development and stress tolerance.

The location of ADC in the chloroplast compartment may have major evolutionary significance, since it explains why plants can use two alternative pathways for putrescine biosynthesis and (b) why animals do not possess ADC.

The cloning of the four missing genes, purification of the enzymes, and identification of their functions are demonstrated and it is shown that the plant synthetase is not CTP-but ATP-dependent.
The maize abscisic acid-responsive protein Rab17 is located in the nucleus and interacts with nuclear localization signals.
The results suggest that Rab17 may play a role in nuclear protein transport and specific binding of Rab17 to the wild-type NLS of the SV40 T antigen but not to an import incompetent mutant peptide is found.
A major isoform of the maize plasma membrane H(+)-ATPase: characterization and induction by auxin in coleoptiles.
It is concluded that auxin-induced acidification in coleoptile segments most often occurs in the nonvascular tissue and is mediated, at least in part, by increased levels of MHA2.
Tomato Transformation and Transgenic Plant Production
When the phenolic acetosyringone was present in the co-culture medium at 200 µM, confirmed transgenic lines reached 50% of antibiotic resistant shoots and the transformation efficiency reached 12.5%.

Two Arabidopsis thaliana genes are isolated, showing homology with HAL3, a yeast protein which regulates the cell cycle and tolerance to salt stress through inhibition of the PPZ1 type-1 protein phosphatase, suggesting possible conserved functions between both proteins.
