lotus digii/proline

Proline accumulation is a common response of plants to different biotic and abiotic stresses. In the model legume Lotus japonicus, osmotic stress-induced proline accumulation is one of the first responses of the plant, converting proline in a reliable stress marker. The main biosynthetic pathway of

The role of plastidic glutamine synthetase (GS2) in proline biosynthesis and drought stress responses in Lotus japonicus was investigated using the GS2 mutant, Ljgln2-2. Wild-type (WT) and mutant plants were submitted to different lengths of time of water and nutrient solution deprivation. Several

In this work we investigated the involvement of Glomus intraradices in the regulation of plant growth, polyamines and proline levels of two Lotus glaber genotypes differing in salt tolerance, after longterm exposure to saline stress. The experiment consisted of a randomized block design with three

The cis/trans isomerization of the peptide bond preceding proline is an intrinsically slow process, although important in many biological processes in both prokaryotes and eukaryotes. In vivo, this isomerization is catalyzed by peptidyl-prolyl cis/trans-isomerases (PPIases). Here, we present the

Higher plants assimilate nitrogen in the form of ammonia through the concerted activity of glutamine synthetase (GS) and glutamate synthase (GOGAT). The GS enzyme is either located in the cytoplasm (GS1) or in the chloroplast (GS2). To understand how modulation of GS activity affects plant

This paper summarizes some recent advances in the understanding of nitrate assimilation in the model legume Lotus japonicus. First, different types of experimental evidence are presented that emphasize the importance of the root in the nitrate-reducing assimilatory processes in this plant. Secondly,

Lotus corniculatus is used in agriculture as a main forage plant. Members of the Apetala2/ethylene response factor (AP2/ERF) family play important roles in regulating gene expression in response to many forms of stress, including drought and salt. Here, starting from database of the L. corniculatus

Water stress is one of the most severe problems for plant growth and productivity. Using the legume Lotus japonicus exposed to water stress, a comparative analysis of key components in metabolism of reactive nitrogen and oxygen species (RNS and ROS, respectively) were made. After water stress

Salt stress negatively affects many physiological processes in plants. Some of these effects may involve the oxidative damage of cellular components, which can be promoted by reactive oxygen species and prevented by antioxidants. The protective role of antioxidants was investigated in Lotus

Members of the Lotus genus are important as agricultural forage sources under marginal environmental conditions given their high nutritional value and tolerance of various abiotic stresses. However, their dry matter production is drastically reduced in cooler seasons, while their response to such
