Nitric oxide (NO) and phospholipase D (PLD) are essential regulators of seed germination in many plant species, but their roles and relationships in seeds that require light for germination are poorly understood. Here, we investigated how NO and PLD regulate lettuce (Lactuca sativa) seed germina...

Nitric acid oxidation of d-mannose was carried out under an oxygen atmosphere using a computer controlled reactor. The process represents a catalytic oxidation of d-mannose with oxygen as the terminal oxidant. The crude oxidation product was esterified with methanolic HCl and the esterified prod...
