Journal ArticleDOI
The Distal Part of the Transition Zone Is the Most Aluminum-Sensitive Apical Root Zone of Maize
Mayandi Sivaguru,Walter J. Horst +1 more
TL;DR: The distal part of the transition zone of the root apex, where the cells are undergoing a preparatory phase for rapid elongation, is the primary target of Al in this Al-sensitive maize cultivar.
Journal ArticleDOI
Aluminum-induced 1→3-β-D-glucan inhibits cell-to-cell trafficking of molecules through plasmodesmata. A new mechanism of aluminum toxicity in plants
Mayandi Sivaguru,Toru Fujiwara,J. Šamaj,František Baluška,Zhenming Yang,Zhenming Yang,Hiroki Osawa,Takanori Maeda,Tomoko Mori,Dieter Volkmann,Hideaki Matsumoto +10 more
TL;DR: The data demonstrate that extracellular Al-induced callose deposition at PD could effectively block symplastic transport and communication in higher plants and suggest that Al-signal mediated localized alterations to calcium homeostasis may drive callose formation and PD closure.
Journal ArticleDOI
Compartmentalization of S-RNase and HT-B degradation in self-incompatible Nicotiana
Ariel Goldraij,Katsuhiko Kondo,Christopher B. Lee,C. Nathan Hancock,Mayandi Sivaguru,Sonia Vázquez-Santana,Sunran Kim,Thomas E. Phillips,Felipe Cruz-García,Bruce McClure +9 more
TL;DR: It is suggested that S-RNase trafficking and the stability of HT-B are central to S-specific pollen rejection.
Journal ArticleDOI
Aluminum-Induced Gene Expression and Protein Localization of a Cell Wall-Associated Receptor Kinase in Arabidopsis
Mayandi Sivaguru,Bunichi Ezaki,Zheng-Hui He,Hongyun Tong,Hiroki Osawa,František Baluška,Dieter Volkmann,Hideaki Matsumoto +7 more
TL;DR: Al-induced organ-specific expression of a WAK1 (cell wall-associated receptor kinase 1) gene and cell type-specific localization of WAK proteins in Arabidopsis are reported and transgenic plants overexpressing Wak1 showed an enhanced Al tolerance in terms of root growth when compared with the wild-type plants, making the WAK 1 one of the important candidates for plant defense against Al toxicity.
Journal ArticleDOI
Impacts of aluminum on the cytoskeleton of the maize root apex. short-term effects on the distal part of the transition zone
Mayandi Sivaguru,František Baluška,František Baluška,Dieter Volkmann,Hubert H. Felle,Walter J. Horst +5 more
TL;DR: The data show that the cytoskeleton in the cells of the DTZ is especially sensitive to Al, consistent with the recently proposed specific Al sensitivity of this unique, apical maize root zone.
