TL;DR: Positional cloning is used to identify the gene encoding a member of the multidrug and toxic compound extrusion (MATE) family, an aluminum-activated citrate transporter, as responsible for the major sorghum aluminum tolerance locus, AltSB, and find superior AltSB haplotypes that can be incorporated via molecular breeding and biotechnology into acid soil breeding programs, thus helping to increase crop yields in developing countries where acidic soils predominate.

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.

TL;DR: AtMATE, a homolog of the recently discovered sorghum and barley Al-tolerance genes, is characterized to encode an Al-activated citrate transporter in Arabidopsis and a link between regulation of expression of the two transporters in response to Al was identified through work on STOP1, a transcription factor that was previously shown to be necessary for AtALMT1 expression.

TL;DR: The HATS for nitrate uptake by barley roots is essentially similar to those reported for Lemna and Zea mays by earlier workers, establishing that there are, nevertheless, distinct differences between barley and corn in their quantitative responses to external NO(3) (-).

TL;DR: A novel imaging and software platform was developed for the high-throughput phenotyping of three-dimensional root traits during seedling development and will facilitate novel investigations into the development of entire root systems or selected components of root systems.
