Abstract: Methods for the production of modified plants are provided. In these methods a first line and a second line are crossed to produce a plant having a phenotypic trait, wherein neither the first or second lines possess the phenotypic trait, and wherein at least one of the parent lines is transgenic. Plants produced by the methods of the invention are also described.

Abstract: Plants, particularly transgenic plants, may be produced having a 2-acyltransferase enzyme or other insoluble acyltransferase enzyme with an altered substrate specificity compared to the native enzyme. For example, oil seed rape (Brassica napus) may contain a 2-acyltransferase transgene derived from Limnanthes douglassi in order to increase the erucic acid content of the oil. The cDNA sequence of maize (Zea mays) 2-acyltansferase is disclosed and is useful for cloning acyltransferase genes and/or cDNAs from other organisms, including L. douglassi.

Abstract: The present invention is directed to methods of controlling plant parasitic nematodes using proteinase inhibitors, particularly those in the Bowman-Birk family which includes cowpea trypsin inhibitors. Nematode resistance can be conferred on plants by transforming them to express a gene or other DNA coding for a proteinase inhibitor using standard genetic engineering techniques. Alternatively, proteinase inhibitors can be provided to nematodes or to the site of their attack.
