What is Anhydrobiosis in nematodes: Biosynthesis of trehalose about?

## Abstract The pathway for the synthesis of trehalose in __Aphelenchus avenae__ was demonstrated. As in other systems, the enzymes involved in the synthesis of trehalose of __A. avenae__ were found to be trehalose phosphate synthetase (TPS) and trehalosephosphate phosphatase (TPP). Some of the characteristics of trehalose phosphate synthetase were studied. It was found that the rate limiting step in the reaction is catalyzed by TPS. Partially purified TPS was specific for UDPG as the glucosyl donor, and showed a pH optimum of 8.0. The partially purified enzyme has a Km of 0.6 mM and a V~max~ of 2.2 × 10^−3^ μmoles/mg protein min for glucose‐6‐phosphate, and a Km of 2.4 mM and V~max~ of 2.5 × 10^−3^ μmoles/mg protein minfor UDPG.
