Molecular analysis of legume nodule development and autoregulation.
Legumes are highly important food, feed and biofuel crops. With few exceptions, they can enter into an intricate symbiotic relationship with specific soil bacteria called rhizobia. This interactionExpand

Strigolactone Acts Downstream of Auxin to Regulate Bud Outgrowth in Pea and Arabidopsis1[C][OA]
During the last century, two key hypotheses have been proposed to explain apical dominance in plants: auxin promotes the production of a second messenger that moves up into buds to repress theirExpand

Inoculation- and nitrate-induced CLE peptides of soybean control NARK-dependent nodule formation.
Systemic autoregulation of nodulation in legumes involves a root-derived signal (Q) that is perceived by a CLAVATA1-like leucine-rich repeat receptor kinase (e.g. GmNARK). Perception of Q triggersExpand

Molecular mechanisms controlling legume autoregulation of nodulation.
BACKGROUND High input costs and environmental pressures to reduce nitrogen use in agriculture have increased the competitive advantage of legume crops. The symbiotic relationship that legumes formExpand

Apical Dominance and Shoot Branching. Divergent Opinions or Divergent Mechanisms?1
Apical dominance is the term used to describe the control of the shoot tip over axillary bud outgrowth (e.g. [Cline, 1997][1]). It is best demonstrated via shoot tip removal (decapitation), whichExpand

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

Soybean miR172c Targets the Repressive AP2 Transcription Factor NNC1 to Activate ENOD40 Expression and Regulate Nodule Initiation[C][W]
Induction of miR172c in response to rhizobial inoculation activates ENOD40 expression and nodule formation by repressing an AP2/ERF transcription factor, called NNC1, that acts to inhibit ENOD40Expand

Roles for Auxin, Cytokinin, and Strigolactone in Regulating Shoot Branching1[C][W][OA]
Many processes have been described in the control of shoot branching. Apical dominance is defined as the control exerted by the shoot tip on the outgrowth of axillary buds, whereas correlativeExpand

MicroRNA167-Directed Regulation of the Auxin Response Factors GmARF8a and GmARF8b Is Required for Soybean Nodulation and Lateral Root Development1[OPEN]
The microRNA miR167 contributes to the nodulation of soybean via auxin response factors. Legume root nodules convert atmospheric nitrogen gas into ammonium through symbiosis with a prokaryoticExpand

Signaling Interactions During Nodule Development
Nitrogen fixing bacteria, collectively referred to as rhizobia, are able to trigger the organogenesis of a new organ on legumes, the nodule. The morphogenetic trigger is a Rhizobium-producedExpand
