The elucidation of gene expression patterns leads to a better understanding of biological processes. Real-time quantitative RT-PCR has become the standard method for in-depth studies of gene expression. A biologically meaningful reporting of target mRNA quantities requires accurate and reliable normalization in order to identify real gene-specific(More)

Indole-3-acetic acid (IAA), the main endogenous auxin, has been known for decades to be a key regulator for plant growth and development. Multiple routes have been proposed for IAA biosynthesis but physiologic roles or relevance of the different routes are still unclear. Recently, four members of the Arabidopsis thaliana YUC gene family have been implicated(More)
Menadione sodium bisulphite (MSB) is a water-soluble derivative of vitamin K3, or menadione, and has been previously demonstrated to function as a plant defence activator against several pathogens in several plant species. However, there are no reports of the role of this vitamin in the induction of resistance in the plant model Arabidopsis thaliana. In the(More)
Using an authentic sample of 2-hydroxy-9-(p-hydroxyphenyl)-phenalen-1-one, a banana phenalenone-type phytoalexin, we studied its dynamic of accumulation during pathogenesis of banana plants (Musa acuminata (AAA), Grand Nain) inoculated with Fusarium oxysporum f.sp. cubense (FOC), Race 4, the causal agent of Panama disease. The results obtained demonstrate(More)
The flavin monooxygenases (FMO) encoded by plant YUCCA genes are thought to catalyze a rate-limiting step in the tryptamine pathway for indole-3-acetic acid biosynthesis. Recent experiments with different plant models have indicate that YUCCA genes play essential roles in growth and development through their contribution to the local pool of free auxin. In(More)

BACKGROUND Snails and slugs are terrestrial gastropods representing an important biotic stress that adversely affects crop yields. These pests are typically controlled with molluscicides, which produce pollution and toxicity and further induce the evolution of resistance mechanisms, making pest management even more challenging. In our work, we have assessed(More)
In order to address the need for production of parthenocarpic fruits, embryogenic cultures of 'Brewster' ('Chen Tze') litchi derived from leaves of a mature tree were transformed with the PISTILLATA (PI) cDNA in antisense orientation through Agrobacterium-mediated transformation. In four independently transformed lines, transgene integration was confirmed(More)
