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
GIBBERELLIN BIOSYNTHESIS: Enzymes, Genes and Their RegulationAnnual Reviews - Tập 48 Số 1 - Trang 431-460 - 1997
Peter Hedden, Yuji Kamiya
▪ Abstract The recent impressive progress in research on gibberellin (GA) biosynthesis has resulted primarily from cloning of genes encoding biosynthetic enzymes and studies with GA-deficient and GA-insensitive mutants. Highlights include the cloning of ent-copalyl diphosphate synthase and ent-kaurene synthase (formally ent-kaurene synthases A and B) and the demonstration that the former ...... hiện toàn bộ
VARIATIONS IN THE BIOSYNTHESIS OF SEED-STORAGE LIPIDSAnnual Reviews - Tập 52 Số 1 - Trang 335-361 - 2001
Toni A. Voelker, Anthony J. Kinney
▪ Abstract In many plants lipids represent up to 80% of dry weight of storage tissues. In seeds, lipids accumulate as triacylglycerols (TAGs), which are formed by an extension of the membrane-lipid biosynthetic pathway common to all plant tissues. In contrast to the conserved fatty acid (FA) composition of membrane lipids, the observed divergence in seed oil acyl chains among different s...... hiện toàn bộ
Genetic Control and Integration of Maturation and Germination Pathways in Seed DevelopmentAnnual Reviews - Tập 46 Số 1 - Trang 71-93 - 1995
Donald R. McCarty
The viviparous and germination mutants of maize and Arabidopsis thaliana illuminate the mechanism that integrates control of morphogenetic, maturation, dormancy, and germination pathways in seed development. Key elements of this mechanism include (a) developmental control of abscisic acid and gibberellin hormone synthesis and perception, (b) integration of maturation and anthocyanin pathw...... 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
