Peroxiredoxins and NADPH-dependent thioredoxin systems in the model legume Lotus japonicus.

Replacement of threonine-55 with glycine decreases the reduction rate of OsTrx20 by glutathione

Thioredoxins (Trxs) are small ubiquitous oxidoreductase proteins with two redox-active Cys residues in a conserved active site (WCG/PPC) that regulate numerous target proteins via thiol/disulfide exchanges in the cells of prokaryotes and eukaryotes. The isoforms OsTrx23 with a typical active site (WCGPC) and OsTrx20 with an atypical active site (WCTPC) are two  Trx h- type isoforms in rice that ...

Lotus Base: An integrated information portal for the model legume Lotus japonicus

Lotus japonicus is a well-characterized model legume widely used in the study of plant-microbe interactions. However, datasets from various Lotus studies are poorly integrated and lack interoperability. We recognize the need for a comprehensive repository that allows comprehensive and dynamic exploration of Lotus genomic and transcriptomic data. Equally important are user-friendly in-browser to...

Recent Progress in Development of Tnt1 Functional Genomics Platform for Medicago truncatula and Lotus japonicus in Bulgaria

Legumes, as protein-rich crops, are widely used for human food, animal feed and vegetable oil production. Over the past decade, two legume species, Medicago truncatula and Lotus japonicus, have been adopted as model legumes for genomics and physiological studies. The tobacco transposable element, Tnt1, is a powerful tool for insertional mutagenesis and gene inactivation in plants. A large colle...

Secondary metabolite profiling of the model legume Lotus japonicus during 2 its symbiotic interaction with Mesorhizobium loti

Voltage-dependent cation channels permeable to NH(+)(4), K(+), and Ca(2+) in the symbiosome membrane of the model legume Lotus japonicus.

The symbiosome of nitrogen fixing root nodules mediates metabolite exchange between endosymbiotic rhizobia bacteria and the legume host. In the present study, the ion currents of the symbiosome membrane of the model legume Lotus japonicus were analyzed by patch-clamp recording. Both excised and symbiosome-attached patches exhibited a large inward (toward the cytosolic side of the membrane) curr...
