5451516 Bifunctional protein from carrots (daucus carota) with aspartokinase and homoserine dehydrogenase activities
PATENT ABSTRACTS
from a variety of sources and for detecting allelic variants not distinguishable by serological methods. This HLA-A DNA typing system can be used in a forward or reverse dot-blot format that is simple and rapid to perform, produces detectable signals in minutes, and can be used for tissue typing, determining individual identity, and identifying disease susceptible individuals.

leading to suppression of lignin synthesis. If the recombinant gene has the lignin enzyme gene in normal, or sense orientation, increased production of the enzyme may occur when the insert is the full length DNA but suppression may occur if only a partial sequence is employed.

BIFUNCTIONAL
METHOD FOR STABLY TRANSFORMING PLASTIDS OF MULTICELLULAR
PLANTS
MaligaPal; MaligaZora S East Brunswick, NJ, UNITED STATES assigned to Rutgers The State University of New Jersey This invention provides methods for obtaining a plant cell ofa multicellular plant, the plastids of which cell have been stably transformed by a foreign DNA of interest. These methods employ selectable markers some of which are nonlethal, some of which are designed to insert into the plastid genome and some of which are designed to be expressible only from the plastid genome and not from the nuclear genome. This invention also provides cells and multicellular plants the plastids of which have been stably transformed by a foreign DNA of interest.

(DAUCUS
CAROTA) WITH ASPARTOKINASE AND HOMOSERINE DEHYDROGENASE
ACTIVITIES
Matthews Benjamin F; Weisemann Jane M Laurel, MD, UNITED STATES An isolated and purified bifunctional protein from carrots with aspartokinase and homoserine activities which can be used to regulate the amino acid content of plants, in particular the lysine, homoserine, threonine, isoleucine and/or methionine content is disclosed. In addition, a DNA molecule with a DNA sequence coding for a homologous segment of the bifunctional carrot protein is also disclosed. In a method of regulating the amino acid content in a plant by bringing an effective amount of the bifunctional protein in contact with the plant is disclosed.

CLONING RESTRICTION ENDONUCLEASE GENES BY MODULATING METHYLTRANSFERASE ACTIVITY
The synthesis oflignin by plants is controlled by transformation of the plant genome with a recombinant gene construct which contains the gene specifying an enzyme critical to the synthesis of a lignin precursor, which gene may be in antisense orientation so that it is transcribed to mRNA having a sequence complementary to the equivalent mRNA transcribed from the endogenous gene thus
