This review examines contemporary views of the role of plant hormones in the control of
physiological processes. Past and present difficulties with nomenclature encapsulate the …

Research on the classical plant hormones continues to uncover fascinating interactions
between these crucial regulatory compounds. Recent papers describe 'cross-talk'between …

In shoots of the garden pea, the bioactive gibberellin (GA1) is synthesised from GA20, and
the enzyme which catalyses this step (a GA 3‐oxidase–‐PsGA3ox1) is encoded by Mendel's …

Auxin is a plant hormone that plays key roles in both shoot gravitropism and inflorescence
development. However, these two processes appear to be parallel and to be regulated by …

Plant growth and development are tightly regulated by phytohormones. However, little is
known about the interaction between auxin and gibberellin acid (GA) during flower stalk …

Multiple gibberellins (GAs) were quantified in the stems of intact, decapitated, and
decapitated auxin-treated barley (Hordeum vulgare) plants. Removal of the developing …

Recently it was discovered that auxin promotes gibberellin (GA) biosynthesis in decapitated
stems of pea (Pisum sativum L.) and tobacco (Nicotiana tabacum L.), and here we review …

Rumex palustris responds to complete submergence with upward movement of the younger
petioles. This so-called hyponastic response, in combination with stimulated petiole …

By differential screening of a cDNA library from auxin-induced maize coleoptiles we have
isolated and characterized a SAUR gene, designated ZmSAUR2, belonging to a not yet …

We isolated a mutant, named coleoptile phototropism1 (cpt1), from γ-ray–mutagenized
japonica-type rice (Oryza sativa). This mutant showed no coleoptile phototropism and …
