Journal ArticleDOI
AtALMT1, which encodes a malate transporter, is identified as one of several genes critical for aluminum tolerance in Arabidopsis
Owen A. Hoekenga,Lyza G. Maron,Miguel A. Piñeros,Geraldo Magela de Almeida Cançado,Geraldo Magela de Almeida Cançado,Jon E. Shaff,Yuriko Kobayashi,Peter R. Ryan,Bei Dong,Emmanuel Delhaize,Takayuki Sasaki,Hideaki Matsumoto,Yoko Yamamoto,Hiroyuki Koyama,Leon V. Kochian +14 more
TL;DR: Results indicate that AtALMT1 is an essential factor for Al tolerance in Arabidopsis but does not represent the major Al tolerance QTL also found on chromosome 1.
Journal ArticleDOI
Novel Properties of the Wheat Aluminum Tolerance Organic Acid Transporter (TaALMT1) Revealed by Electrophysiological Characterization in Xenopus Oocytes: Functional and Structural Implications
TL;DR: The lack of change in the reversal potential (Erev) upon exposure to Al3+ suggests that the “enhancement” of TaALMT1 malate transport by Al is not due to alteration in the transporter's selectivity properties but is solely due to increases in its anion permeability.
Journal ArticleDOI
Not all ALMT1-type transporters mediate aluminum-activated organic acid responses: the case of ZmALMT1 - an anion-selective transporter
Miguel A. Piñeros,Geraldo Magela de Almeida Cançado,Lyza G. Maron,Sangbom M. Lyi,Marcelo Menossi,Leon V. Kochian +5 more
TL;DR: In this paper, a maize gene homologous to the wheat ALMT1 and Arabidopsis AtALMT1 genes was cloned, and physiological, gene expression and functional data from this study confirm that ZmALMT 1 is a plasma membrane transporter that is capable of mediating elective anion efflux and influx.
Journal ArticleDOI
Hematoxylin staining as a phenotypic index for aluminum tolerance selection in tropical maize (Zea mays L.)
Geraldo Magela de Almeida Cançado,Leandro Lopes Loguercio,P. R. Martins,Sidney Netto Parentoni,Edilson Paiva,Aluízio Borém,Mauricio A. Lopes +6 more
TL;DR: Evaluation of the results from diallel crosses involving nine inbred lines proved that hematoxylin staining was particularly adequate for identifying expressive hybrid vigor, as demonstrated by the general (GCA) and specific (SCA) combining ability estimates obtained by using the three indexes simultaneously.
Journal ArticleDOI
An improved method for genomic DNA extraction from strawberry leaves
Claudinéia Ferreira Nunes,Juliano Lino Ferreira,Mônique Carolina Nunes Fernandes,Sâmera de Souza Breves,Andressa Leal Generoso,Bárbara Dantas Fontes Soares,Mário Sérgio Carvalho Dias,Moacir Pasqual,Aluízio Borém,Geraldo Magela de Almeida Cançado +9 more
TL;DR: In this article, the authors evaluated the quality and amount of genomic DNA extracted from young leaves of strawberry after tissue lyophilization and maceration in presence of polivinilpirrolidone (PVP).
