Project description:This dataset includes RNAseq data of 7 tissues/developmental stages of Lathyrus sativus genotype LSWT11 and 2 tissues with drought- and well-watered treatments of Lathyrus sativus genotypes LS007 and Mahateora. These data were used in the functional annotation pipeline of the Rbp1.0 genome assembly of LS007. The multi-tissue transcriptome was also used to support gene candidate identification by mRNA abundance. Also included is Hi-C sequencing data used to scaffold the assembly into pseudochromosomes
Project description:Grass pea seeds and seedlings protein extracts were chromatographically fractionated. To identify the β-ODAP synthase enzyme, active fractions, as determined by a colorimetric assay that detects the presence of a derivative of free L-α,β-diaminopropionic acid (L-DAPA), were subjected to tryptic digestion and LC-MS/MS and searched against a database containing translated sequences from a long-read PacBio mRNA sequencing of grass pea seeds and seedlings.
Project description:An enzyme catalysing the synthesis of sym-homospermidine from putrescine and NAD+ with concomitant liberation of NH3 was purified 100-fold from Lathyrus sativus (grass pea) seedlings by affinity chromatography on Blue Sepharose. This thiol enzyme had an apparent mol.wt. of 75000 and exhibited Michelis-Menten kinetics with Km 3.0mM for putrescine. The same enzyme activity could also be demonstrated in the crude extracts of sandal (Santalum album) leaves, but with a specific activity 15-fold greater than that in L. sativus seedlings.
