Molecular Oral Microbiology, EarlyView.We report optimization of the Treponema denticola shuttle plasmid system by minimizing its size and by characterizing an array of promoter‐gene constructs for genetic complementation, including the first use in Treponema of a Tet‐inducible system for controlled expression of potentially toxic genes.

KNR4, a suppressor of Saccharomyces cerevisiae cwh mutants, is involved in the transcriptional control of chitin synthase genes [PDF]
, 1999 The KNR4 gene, originally isolated by complementation of a K9 killer-toxinresistant mutant displaying reduced levels of both 1,3-b-glucan and 1,3-bglucan synthase activity, was recloned from a YCp50 genomic library as a suppressor of Saccharomyces ...

Plant Biotechnology Journal, EarlyView.ABSTRACT Catharanthus roseus contains nearly 200 bioactive monoterpenoid indole alkaloids (MIAs) that are effective in treating cancer and other diseases. Ethylene plays a significant role in enhancing MIA biosynthesis, and we have found that it greatly induces the accumulation of anhydrovinblastine.

Un environnement formel d'assistance à la modélisation de protocoles [PDF]
, 2008 The use of protocol design toolkits based on UML profiles has been hampered by the lack of methodological support. Indeed, those toolkits should include an assistant based on patterns and dedicated to driving the designer step by step through a well ...

Plant Biotechnology Journal, EarlyView.ABSTRACT Anthocyanin biosynthesis in non‐climacteric grape berries is regulated through coordinated phytohormonal signalling networks. However, the precise mechanisms by which abscisic acid (ABA), brassinosteroids (BRs) and ethylene (ET) synergistically modulate this process remain unclear.

Plant Biotechnology Journal, EarlyView.ABSTRACT Phosphorus is indispensable in agricultural production. The growing global demand for food necessitates the development of crops with enhanced phosphorus utilisation efficiency. However, the molecular mechanisms coordinating phosphorus utilisation efficiency in plants remain incompletely characterised.
