N2 - Microsomal fractions from developing shoots of adult white clover plants (of genotype Ac Ac) and cotyledons of dark germinated clover seedlings can synthesize 2-hydroxy-2-methylpropanenitrile and 2-hydroxy-2-methylbutanenitrile, the aglycone precursors of the cyanogenic glucosides, linamarin and lotaustralin, from various precursors in the presence of NADPH. l-Valine, 2-methylpropanal oxime, and 2-methylpropanenitrile are converted to 2-hydroxy-2-methylpropanenitrile and are detected as cyanide and acetone. l-Isoleucine and 2-methylbutanal oxime are converted to 2-hydroxy-2-methylbutanenitrile and are detected as cyanide and 2-butanone. At least two steps in these conversions are missing in microsomes from plants of genotype ac ac.
