The production of secondary metabolites and nitrogen metabolism are interconnected. Various secondary metabolites of plants have been used for a long time either in human treatment, industry or agriculture. Nitrogen is a frequent limiting factor for plant growth and productivity. The project will evaluate how nitrogen from different sources can influence the metabolome profiles of phenols under physiological and stress conditions. The knowledge about the role of cytokinins, jasmonic acid and salicylic acid in eliciting the formation of secondary metabolites in medicinal plants Taraxacum sp. and Matricaria chamomilla L. Since nitrogen metabolism is closely connected with carbon metabolism, selected aspects of the interaction of N/C metabolism will be compared and clarified using mutants of model plants (Arabidopsis thaliana, Lotus japonicus) in cooperation with foreign partners. Qualitative and quantitative representation of metabolites (phenols - coumarins, flavonoids, chlorogenic acids and others) will be analyzed by NMR, HPLC-DAD and LC-MS methods.

The present project focuses on the regulation of the biosynthesis of isoflavonoids, which are important from the point of view of plant defense, symbioses with bacteria fixing atmospheric nitrogen, as well as from the point of view of human use. Model plants will be used for these purposes from the Fabaceae family, which are objects of intensive research, while also having significant specificities of their secondary metabolism. Mutants obtained by reverse genetics methods with altered production of regulatory substances are available for these plants with predicted changes in the biosynthesis of phenolic substances. Knowledge obtained from model objects will be compared with relatives species with economic importance. Regulation of the formation of isoflavonoids will be studied by a combination of analytical (HPLC-DAD, LC-MS, NMR) and molecular biological methods (qRT-PCR) under stress conditions. By synthesizing these results, we get a comprehensive view on the way plants regulate the production of defense substances. The research of phenolic substances has a promising potential for the use of knowledge in agriculture, pharmaceutical and food industry.

This project is aimed to the study of different legume mutants affected in genes related

to productivity, in order to improve the yield of a very important legume crop such as soybean. Three different classes of genes will

be studied: 1) two genes involved in asparagine biosynthesis, an amino acid that plays a key role in nitrogen metabolism in legumes

and is also involved in plant development, seed production and in the response to abiotic stress conditions such as drought. 2) Genes

encoding for two transcription factors highly connected to the biosynthesis of isoflavonoids, molecules of fundamental importance in

the rhizobial-legume symbiosis and in the response to drought, and 3) genes encoding for two transcription factors highly connected

to nitrogen assimilation and photorespiration, two very important processes for plant productivity and for the response to drought

stress. These genes were identified by transcriptomic data analysis combined with a gene co-expression study carried out using a

gene co-expression network that was developed in the previously funded AGL project. We have already available specific mutants

affected in each one of these genes which have been obtained from the collection of LORE1 transposon-tagged mutants from the

model legume Lotus japonicus. In this project we will carry out the molecular and phenotypic characterization of these mutants. It

is encouraging that some of the mutant plants show increased biomass. A comparative analysis of WT and mutant plants growing

either under symbiotic or non-symbiotic conditions will be carried out. Moreover, the capacity of the mutants to establish symbiosis

with nitrogen-fixing bacteria and to withstand drought conditions will be determined. In addition, and in parallel with the studies with

L. japonicus, CRISPR/Cas9 technology will be used to disrupt genes from soybean whose knockout result in L. japonicus increased

productivity, better symbiotic capacity and/or higher drought tolerance. We will proceed first to the disruption of genes for Asn

biosynthesis in soybean since preliminary data indicate that the knockout of these genes in L. japonicus is associated to increased root

biomass. The soybean mutant plants generated will be tested for their productivity and their response to drought stress conditions.
