The callose synthase (CalS) activity of membrane preparations from cultured Nicotiana alata Link & Otto pollen tubes is increased several-fold by treatment with trypsin in the presence of digitonin, possibly due to activation of an inactive (zymogen) form of the enzyme. Active and inactive forms of CalS are also present in stylar-grown tubes. Callose deposition was first detected immediately after germination of pollen grains in liquid medium, at the rim of the germination aperture. During tube… CONTINUE READING
