Abstract:Salt stress is one of the most common factors limiting plant cultivation. In this study, metabolic responses to salt stress in Arabidopsis thaliana (A. thaliana) leaves were analyzed in situ by neutral desorption-extractive electrospray ionization mass spectrometry (ND-EESI-MS) without any
Al-resistant (alr) mutants of Arabidopsis thaliana were isolated and characterized to gain a better understanding of the genetic and physiological mechanisms of Al resistance. alr mutants were identified on the basis of enhanced root growth in the presence of levels of Al that strongly inhibited
The extent of aluminium internalization during the recovery from aluminium stress in living roots of Arabidopsis thaliana was studied by non-invasive in vivo microscopy in real time. Aluminium exposure caused rapid depolarization of the plasma membrane. The extent of depolarization depends on the
Magnesium (Mg2+) plays a critical role in many physiological processes. The AtMRS2/MGT family, which consists of nine Arabidopsis genes (and two pseudo-genes) belongs to a eukaryotic subset of the CorA superfamily of divalent cation transporters. AtMRS2-10 and AtMRS2-1 possess the signature
Al-sensitive (als) mutants of Arabidopsis were isolated and characterized with the aim of defining mechanisms of Al toxicity and resistance. Most als mutants selected on the basis of root growth sensitivity to Al were recessive, and together the mutants constituted eight complementation groups.
To examine the biological role of Al-stress-induced genes, nine genes derived from Arabidopsis, tobacco (Nicotiana tabacum L.), wheat (Triticum aestivum L.), and yeast (Saccharomyces cerevisiae) were expressed in Arabidopsis ecotype Landsberg. Lines containing eight of these genes were
