We have previously demonstrated that the double bond of petroselinic acid (18:1[delta]6cis) in coriander (Coriandrum sativum L.) seed results from the activity of a 36-kD desaturase that is structurally related to the [delta]9-stearoyl-acyl carrier protein (ACP) desaturase (E.B.

An indirect method of quantifying in vitro pollen growth has been developed. This is based on the finding that a monoclonal antibody (PCBC3), which has a primary specificity for alpha-l-arabinofuranosyl residues, binds to the surface of in vitro grown pollen tubes of the ornamental tobacco,
