Patent CA-2340937-A1 (CA)
Title: A new method of identifying non-host plant disease resistance genes
Inventor: YAN HUA
IPC: C12Q1/02
Filed: 1999-08-31
Abstract: The invention describes a new method to isolate disease resistance genes in plants. The method teaches to transiently express in susceptible plants large numbers of R-gene homologs or non-host inducible genes isolated from non-host resistant plants. These plants can be screened for either disease resistance or ability to respond with a hypersensitive response to pathogen-elicitor subjection. The invention also reports several R-genes and non-host inducible genes that have been successfully isolated using the described method. These R-genes trigger a hypersensitive response in tobacco that is dependent on the presence of the ubiquitous P. infestans elicitor INF1. The presentedR-genes are predicted to be both the first R-genes isolated that confer resistance against P. infestans and the first R-genes involved in non-host resistance.

Title: Polyester yarn and its method of production
Inventor: MOCHIZUKI KATSUHIKO
IPC: D01F6/62
Filed: 2000-11-15
Abstract: The present invention relates to polyester yarn which is characterized in that it is a multifilament yarn substantially comprising polytrimethylene terephthalate, and as well as the strength from the stress-strain curve being at least 3 cN/dtex and the Young's modulus being no more than 25 cN/dtex, the minimum value of the differential Young's modulus at 3-10% extension is no more than 10 cN/dtex and the elastic recovery following 10% elongation is at least 90%.     Furthermore, said polyester yarn can be obtained by a method of producing polyester yarn which is characterized in that multifilament yarn obtained by the melt spinning of polymer substantially comprising polytrimethylene terephthalate of intrinsic viscosity [.eta.] at least 0.7 is hauled-off at a spinning rate of at least 2000 m/min and, without winding up, subjected to drawing and heat-treatment, after which it is continuously subjected to a relaxation heat treatment at a relaxation factor of 6 to 20% and wound up as a package.     Moreover, the present invention also relates to a woven material of outstanding soft-stretchability which is characterized in that the aforesaid polyester yarn is used as the warp yarn and/or the weft yarn in the form of twisted yarn of twist coefficient 10,000 to 20,000.  In this way, it is possible to produce yarn stably at a high yarn production rate without package tightening occurring, and, as well as there being little variation in properties in the fibre lengthwise direction, when made into fabric, said fabric stretches at low modulus so there is little sense of tightness, and it is possible to provide polyester yarn and woven materials with a soft handle.
