Title: Procedes d'identification de genes sensibles a la gibberelline a l'aide de cellules vegetales cultivees
Inventor: SHIBUYA NAOTO
IPC: C12Q1/68
Filed: 2002-12-20
Abstract: Aucune étude antérieure n'a porté sur des cellules cultivées sensibles à la gibbérelline. Pour identifier et isoler de manière globale et pratique les gènes sensibles à la gibbérelline, il convient d'utiliser des cellules cultivées uniformes et facile à manipuler. Compte tenu des avantages des cellules cultivées, on a tenté de mettre sur pied un procédé d'identification et d'isolation des gènes sensibles à la gibbérelline qui fait intervenir des cellules cultivées. Les cellules cultivées ont d'abord été pré-cultivées dans un milieu exempt d'auxine. Que des changements de l'expression génique aient été détectés ou non, ces cellules ont toutes été examinées. Le résultat a montré, de façon surprenante, que l'expression de certains gènes subit un changement après le traitement à la gibbéreline.

Patent CA-2488531-A1 (CA)
Inventor: HAPPEL KENNETH M
IPC: G06K9/68
Filed: 2003-06-02
Abstract: An improved method is provided for solving sequence matching and comparison problems using attractor-based processes to extract identity tokens that indicate sequence and subsequence symbol content and order. These attractor processes map the sequence from its original sequence representation space (OSRS) into a hierarchical multidimensional attractor space (HMAS). The HMAS can be configured to represent equivalent symbol distributions within two symbol sequences or perform exact symbol sequence matching. The mapping process results in each sequence being drawn to an attractor in the HMAS. Ea ch attractor within the HMAS forms a unique token for a group of sequences with no overlap between the sequence groups represented by different attractors. The size of the sequence groups represented by a given attractor can be reduced from approximately half of all possible sequences to a much smaller subset of possible sequences. The mapping process is repeated for a given sequence so that tokens are created for the whole sequence and a series of subsequences created by repeatedly removing a symbol from the one end of sequence and then repeating the process from the other end. The resulting string of tokens represents the exact identity of the whole sequence and all its subsequences ordered from eachend.
