Aldehyde Dehydrogenases Function in the Homeostasis of Pyridine Nucleotides in Arabidopsis thaliana (OA)

Sci. Rep. Aldehyde dehydrogenase enzymes (ALDHs) are very common proteins involved in the oxidation of aliphatic and aromatic aldehydes to their corresponding carboxylic acids, using NAD and NADP as electron acceptors. In this paper the authors explore the hypothesis that ALDHs are also important…

Nicotinamide Mononucleotide and Related Metabolites Induce Disease Resistance Against Fungal Phytopathogens in Arabidopsis and Barley (OA)

Sci. Rep. Plant defense activators are organic molecules that do not possess antimicrobial activity but have been shown to enhance plant disease resistance mechanisms. A comparison of some Fusarium-resistant and -susceptible barely cultivars suggested that NMN may act as a plant defense activator. RNAseq…

Genomic Insights into the Evolution of the Nicotine Biosynthesis Pathway in Tobacco (OA)

Plant Physiol. Nicotine is a NAD-related secondary alkaloid found in high concentration in the leaves of the tetraploid tobacco plant (Nicotiana tabacum). The recent sequencing of the N. tabacum genome allowed a comprehensive analysis of genes involved in NAD and nicotine biosynthesis. The analysis…
