Sensitive varieties apprently respire mainly by the glycolysis pathway whereas resistant varieties depend more on the pentose phosphate pathway.

Glucose-6-phosphate dehydrogenase (G6PDH) and 6-phosphaogluconate dehydrogenase (6PGDH) are key enzymes in the plant pentose phosphate pathway.

This study facilitated the research on the roles of pentose phosphate pathway in the osmoadaptation and glycerol metabolism in…
