Assays of the key enzymes related to fermentation process following inhibition of 2-OGDHC by phosphonate analogous.

	Control	SP	CESP
	μmol min−1 g−1 FW
Alcohol dehydrogenase	38.2 ± 4.1	35.9 ± 2.9	41.5 ± 4.1
Alanine amino transferase	98.7 ± 10.7	82.9 ± 17.4	97.5 ± 9.9

Fully expanded leaves of 4-week-old were harvested at the middle of the light period, washed three times with 10 mM MES-KOH (pH 6.5), and then incubated during 4 h in similar light growth conditions in 10 mM MES-KOH buffer (pH 6.5) containing 100 μM of SP or CESP. Values are presented as the mean ±SE of six biological replicates.
