Title: Non-transgenic herbicide resistant plants
Inventor: METZ RICHARD A
IPC: C12N15/09
Filed: 2000-10-10
Abstract: The present invention relates to the production of a non-transgenic plant resistant or tolerant to a herbicide of the phosphonomethylglycine family, e.g., glyphosate. The present invention also relates to the use of a recombinagenic Oligonucleobase to make a desired mutation in the chromosomal  or episomal sequences of a plant in the gene encoding for 5-enol pyruvylshikimate-3-phosphate synthase (EPSPS). The mutated protein, which substantially maintains the catalytic activity of the wild-type protein, allows for increased resistance or tolerance of the plant to a herbicide of the phosphonomethylglycine family, and allows for the substantially normal growth or development of the plant, its organs, tissues or cells as compared  to the wild-type plant irrespective of the presence or absence of the herbicide. The present invention also relates to a non-transgenic plant cell  in which the EPSPS gene has been mutated, a non-transgenic plant regenerated  therefrom, as well as a plant resulting from a cross using a regenerated non - transgenic plant having a mutated EPSPS gene.

Title: Bistable liquid crystal devices
Inventor: MILLER RICHARD JONATHAN
IPC: G02B5/30
Filed: 2001-07-11
Abstract: In a liquid crystal device a substrate (1) favours at least two stable or metastable differently directed liquid crystal alignments, and switching mea ns for causing the liquid crystal material to switch between the alignments includes means arranged for optically irradiating said device. The latter ma y provide linearly polarised light (3) for inducing a torque on the liquid crystal to determine the alignment direction, and may optionally cooperate with a second energy supplying means such as an electric field (V) for assisting and switching. Alternatively, the alignment of the liquid crystal may be switched by a second energy supplying means such as an electric field , the light serving to produce heat to aid the switching. Either or both energ y sources may be applied locally for switching of selected areas or pixels. Energy levels at the bistable substrate may be adjusted by the use of an oligomeric additive (slippery surface). As shown, the alignment at the surfa ce of an opposed substrate (2) optionally follows the alignment at substrate (1 ).
