Salicornia seems to be a suitable euhalophyte for the study of salt stress resilience mechanism and exploitation of salinity-tolerant genes for crop yield improvement. In this study, we cloned a novel SePSY1 gene from an extremely salt-tolerant glycophyte, Salicornia europaea. The sequence analysis revealed that the newly isolated gene is a paralog of PSY, suggesting a gene duplication event in Salicornia. The newly isolated gene encodes a protein of 419 amino acids. The C-terminus containing a Trans-IPPS-H domain with catalytic and binding regions exhibits considerable conservation in various species, while the N-terminus remained divergent. The structural analysis suggested a catalytic …

Vitamin E is a group of compounds that includes metabolites known as tocopherols, which have high antioxidant activities. Tocopherols are synthesized in plants, and their beneficial effects on human health have been reported for diseases such as coronary heart disease and cancer. Here we report the full-length transcripts encoding vitamin E biosynthetic enzymes from fruit mesocarp tissues using the rapid amplification of cDNA ends (RACE) method for the first time in olives. We characterized the structure of the genes 4-hydroxyphenylpyruvate dioxygenase (PDS1), homogentisate phytyltransferase 1 (HPT1), vitamin E defective 3 (VTE3), tocopherol cyclase (VTE1), and gamma tocopherol methyltransferase (GTMT), which …
