Patent number: 9163255Abstract: Polynucleotides isolated from chickpea are disclosed herein. The disclosed polynucleotides of the present invention provide genotype-dependent spatial information on the presence and relative abundance of each gene. The transcriptomic analysis of the polynucleotides revealed (649) non-cannonical genes besides many unexpected candidates with known biochemical functions, which have never been associated with pathostress-responsive transcriptome. The polynucleotides disclosed in the present invention can be used as a molecular tool for isolation of novel genes from plants that can be used for plant improvement. Further, the polynucleotide responsible for improving immunity against fungal pathogen in plants is disclosed herein. The present invention also provides a method of improving immunity against fungal pathogen in plants. Transgenic plants exhibiting improved immunity against fungal pathogen are also provided in the present invention.Type: GrantFiled: August 30, 2010Date of Patent: October 20, 2015Assignee: National Institute of Plant Genome ResearchInventors: Subhra Chakraborty, Niranjan Chakraborty, Asis Datta, Nasheeman Asraf, Swaraj Basu, Papri Nag, Manindra Singh

Patent number: 8649125Abstract: The application discloses pole tip shield assemblies for a magnetic write element. The shield assemblies disclosed include side shields to limit adjacent track interference. The side shields are truncated or notched at a midpoint to form an expanded non-magnetic gap along a trailing portion of the pole tip to enhance write field and/or field gradient. The expanded non-magnetic gap region is larger than the non-magnetic gap region along a leading portion of the pole tip.Type: GrantFiled: September 14, 2012Date of Patent: February 11, 2014Assignee: Seagate Technology LLCInventors: Swaraj Basu, Alex Yu Loong Wong, Muhammad Asif Bashir, Mark Gubbins, Robert W.
