Journal ArticleDOI
Reactive oxygen species and ethylene play a positive role in lateral root base nodulation of a semiaquatic legume
Wim D'Haeze,Riet De Rycke,René Mathis,Sofie Goormachtig,Sophie Pagnotta,Christa Verplancke,Ward Capoen,Marcelle Holsters +7 more
TL;DR: Pharmacological experiments showed that ethylene and reactive oxygen species mediate Nod factor responses and are required for nodule initiation, whereby induction of division and infection could not be uncoupled.
Journal ArticleDOI
Calcium spiking patterns and the role of the calcium/calmodulin-dependent kinase CCaMK in lateral root base nodulation of Sesbania rostrata.
Ward Capoen,Ward Capoen,Ward Capoen,Jeroen Den Herder,Jeroen Den Herder,Jongho Sun,Christa Verplancke,Christa Verplancke,Annick De Keyser,Annick De Keyser,Riet De Rycke,Riet De Rycke,Sofie Goormachtig,Sofie Goormachtig,Giles E. D. Oldroyd,Marcelle Holsters,Marcelle Holsters +16 more
TL;DR: In parallel experiments, knockdown of the calcium/calmodulin-dependent protein kinase gene of S. rostrata abolished nodule development but not the formation of infection pockets by intercellular invasion at lateral root bases, suggesting that the colonization of the outer cortex is independent of Ca2+ spiking decoding.
Journal ArticleDOI
Seven in Absentia Proteins Affect Plant Growth and Nodulation in Medicago truncatula
Griet Den Herder,Annick De Keyser,Riet De Rycke,Stephane Rombauts,Willem Van de Velde,María R. Clemente,Christa Verplancke,Peter Mergaert,Eva Kondorosi,Marcelle Holsters,Sofie Goormachtig +10 more
TL;DR: A function for SINA E3 ligases in a broad spectrum of plant developmental processes, including nodulation, is illustrated by extensive microscopic analysis of 35S:SINAT5DN transgenic plants.
Journal ArticleDOI
Role of nodl and nodj in lipo‐chitooligosaccharide secretion in Azorhizobium caulinodans and Escherichia coli
Manuel Fernández-López,Wim D'Haeze,Peter Mergaert,Christa Verplancke,Jean-Claude Promé,Marc Van Montagu,Marcelle Holsters +6 more
TL;DR: In E. coli as well as in Azorhizobium, the nod/J‐encoded transporter showed a specificity for more hydrophilic LCOs, and was strongly reduced in the nodJ mutant, and restored to wild‐type levels after complementation.
Journal ArticleDOI
Srchi24, a chitinase homolog lacking an essential glutamic acid residue for hydrolytic activity, is induced during nodule development on Sesbania rostrata.
Sofie Goormachtig,Willem Van de Velde,Sam Lievens,Christa Verplancke,Sylvia Herman,Annick De Keyser,Marcelle Holsters +6 more
TL;DR: Sequence analyses revealed that Srchi24 is similar to class III chitinases, but lacks an important catalytic glutamate residue, and a function in nodulation is proposed for the Srchi 24 protein.
