MYC2 Differentially Modulates Diverse Jasmonate-Dependent Functions in Arabidopsis[W]
The Arabidopsis thaliana basic helix-loop-helix Leu zipper transcription factor (TF) MYC2/JIN1 differentially regulates jasmonate (JA)-responsive pathogen defense (e.g., PDF1.2) and wound responseExpand

Seed dormancy and ABA metabolism in Arabidopsis and barley: the role of ABA 8'-hydroxylase.
We have investigated the relationship between seed dormancy and abscisic acid (ABA) metabolism in the monocot barley and the dicot Arabidopsis. Whether dormant (D) or non-dormant (ND), dry seed ofExpand

Sugar demand, not auxin, is the initial regulator of apical dominance
Significance It is commonly accepted that the plant hormone auxin mediates apical dominance. However, we have discovered that apical dominance strongly correlates with sugar availability and notExpand

Evidence that auxin promotes gibberellin A1 biosynthesis in pea.
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 LE gene. It hasExpand

Plant hormones in arbuscular mycorrhizal symbioses: an emerging role for gibberellins.
BACKGROUND AND AIMS Arbuscular mycorrhizal symbioses are important for nutrient acquisition in >80 % of terrestrial plants. Recently there have been major breakthroughs in understanding the signalsExpand

Defective Long-Distance Auxin Transport Regulation in the Medicago truncatula super numeric nodules Mutant1[W]
Long-distance auxin transport was examined in Medicago truncatula and in its supernodulating mutant sunn (super numeric nodules) to investigate the regulation of auxin transport during autoregulationExpand

Gibberellin 2-oxidation and the SLN gene of Pisum sativum.
Two cDNAs encoding gibberellin 2-oxidases were isolated from maturing pea seeds. The first, PsGA2ox1, was isolated by activity screening of a Lambda-ZAP cDNA library excised into phagemid form andExpand

Nodulation Phenotypes of Gibberellin and Brassinosteroid Mutants of Pea1
The initiation and development of legume nodules induced by compatible Rhizobium species requires a complex signal exchange involving both plant and bacterial compounds. Phytohormones have beenExpand

Auxin Biosynthesis in Pea: Characterization of the Tryptamine Pathway1[W][OA]
One pathway leading to the bioactive auxin, indole-3-acetic acid (IAA), is known as the tryptamine pathway, which is suggested to proceed in the sequence: tryptophan (Trp), tryptamine,Expand

EARLY FLOWERING3 Regulates Flowering in Spring Barley by Mediating Gibberellin Production and FLOWERING LOCUS T Expression[C][W]
This work shows that the early flowering and growth phenotypes of mutants of barley EARLY FLOWERING3 are promoted by increased production of gibberellin (GA). The authors find that GA is required forExpand
