Leaf growth is a complex developmental process that is continuously fine-tuned by the environment. Various abiotic stresses, including mild drought stress, have been shown to inhibit leaf growth in Arabidopsis (Arabidopsis thaliana), but the underlying mechanisms remain largely unknown. Here, we identify the redundant Arabidopsis transcription factors ETHYLENE RESPONSE FACTOR5 (ERF5) and ERF6 a...
A polar gibberellin active in the dwarf rice (Oryza sativa L.) seedling and barley (Hordeum vulgare L.) half-seed assays was extracted from immature sour cherry (Prunus cerasus L.) seed and identified as gibberellin A(32) by gas-liquid chromatography and selected ion monitoring.
M etolachlor and excess Mn:+ (acid soil stress) induce alterations in gibberellin precursor biosynthesis that can explain the morphological responses to these physiological stresses. Oxa betrinil protects sorghum [Sorghum bicolor (L.) Moench] from the influence o f metolachlor and excess Mn2+. Sorghum cultivar variations in response to excess M n2+ are explicable as dif ferential rates o f tv...
For many years, the plant hormones auxin, cytokinin, ethylene, gibberellin, abscisic acid, brassinosteroid, jasmonic acid, and salicylic acid have been extensively studied as key regulators of plant growth and development. However, recent biochemical and genetic analyses have revealed that secretory peptides are also responsible for intercellular signaling in plants and regulate various events ...
Previously we reported the first example of peptide mimics of a small hydrophobic molecule, a phytohormone gibberellin. The second peptide mimic of gibberellin has been identified from random peptide libraries by its affinity to a type of catalyzing enzyme of gibberellins, which specifically recognizes bioactive gibberellins. These results suggest that even hydrophobic compounds can be mimicked...
A cDNA clone corresponding to a gibberellin-responsive gene (CRG16) was isolated from cucumber hypocotyls. CRG16 was deduced to encode an extremely hydrophobic protein of 65 amino acids. The deduced sequence exhibited no significant homology to other proteins. Levels of CRG16 mRNA reflected the gibberellin-induced elongation of cucumber hypocotyls.
