lotus arinagensis/hypoxia

Formate dehydrogenases (FDHs, EC 1.2.1.2) comprise a group of enzymes found in both prokaryotes and eukaryotes that catalyse the oxidation of formate to CO(2). FDH1 from the model legume Lotus japonicus (LjFDH1) was cloned and expressed in E. coli BL21(DE3) as soluble active protein. The enzyme was

The role of nitrogen metabolism in the survival of prolonged periods of waterlogging was investigated in highly flood-tolerant, nodulated Lotus japonicus plants. Alanine production revealed to be a critical hypoxic pathway. Alanine is the only amino acid whose biosynthesis is not inhibited by

Research on legume nodule metabolism has contributed greatly to our knowledge of primary carbon and nitrogen metabolism in plants in general, and in symbiotic nitrogen fixation in particular. However, most previous studies focused on one or a few genes/enzymes involved in selected metabolic pathways

Plant hemoglobins (Hbs) are found in nodules of legumes and actinorhizal plants but also in non-symbiotic organs of monocots and dicots. Non-symbiotic Hbs (nsHbs) have been classified into two phylogenetic groups. Class 1 nsHbs show an extremely high O2 affinity and are induced by hypoxia and nitric

Flooding severely limits plant growth even for some aquatic plants. Although much work has been done on submergence response of some important crop plants, little is known about the response mechanism of aquatic plants, i.e. lotus (Nelumbo nucifera). In this study, we investigated the genome-wide
