ABSCISIC ACID SIGNAL TRANSDUCTIONAnnual Reviews - Tập 49 Số 1 - Trang 199-222 - 1998
Jeffrey Leung, Jérôme Giraudat
▪ Abstract The plant hormone abscisic acid (ABA) plays a major role in seed maturation and germination, as well as in adaptation to abiotic environmental stresses. ABA promotes stomatal closure by rapidly altering ion fluxes in guard cells. Other ABA actions involve modifications of gene expression, and the analysis of ABA-responsive promoters has revealed a diversity of potential cis-act...... hiện toàn bộ
PLANT TRANSFORMATION: Problems and Strategies for Practical ApplicationAnnual Reviews - Tập 48 Số 1 - Trang 297-326 - 1997
Robert G. Birch
▪ Abstract Plant transformation is now a core research tool in plant biology and a practical tool for cultivar improvement. There are verified methods for stable introduction of novel genes into the nuclear genomes of over 120 diverse plant species. This review examines the criteria to verify plant transformation; the biological and practical requirements for transformation systems; the ...... hiện toàn bộ
REGULATION OF LIGHT HARVESTING IN GREEN PLANTSAnnual Reviews - Tập 47 Số 1 - Trang 655-684 - 1996
Peter Horton, Alexander V. Ruban, Robin Walters
▪ Abstract When plants are exposed to light intensities in excess of those that can be utilized in photosynthetic electron transport, nonphotochemical dissipation of excitation energy is induced as a mechanism for photoprotection of photosystem II. The features of this process are reviewed, particularly with respect to the molecular mechanisms involved. It is shown how the dynamic proper...... hiện toàn bộ
SELENIUM INHIGHERPLANTSAnnual Reviews - Tập 51 Số 1 - Trang 401-432 - 2000
Norman Terry, Adel Zayed, Mark P. de Souza, Alice S. Tarun
▪ Abstract Plants vary considerably in their physiological response to selenium (Se). Some plant species growing on seleniferous soils are Se tolerant and accumulate very high concentrations of Se (Se accumulators), but most plants are Se nonaccumulators and are Se-sensitive. This review summarizes knowledge of the physiology and biochemistry of both types of plants, particularly with reg...... hiện toàn bộ
