Hold the bud tightly at its base, using the thumb and first finger of your left hand, and cut off the front sepal. We have evaluated the use of PCR and fluorescent in situ hybridization (FISH) techniques for the detection of thermotolerant campylobacters in naturally contaminated chicken products. genera, they are generally termed as distant hybridization (or) wide hybridization History Thomas Fairchild 1717 was the first man to do distant hybridization. We have developed in situ hybridization methodology for nonisotopically labeled oligonucleotide probes to detect cellular mRNA with improved speed, convenience, and resolution over previous techniques. Use suitable techniques to overcome barriers to interspecific hybridization in Cicer. 3. 710 . The technique was optimized and validated using tissue from experimentally-infected chicken embryos. Interspecific hybridization between C. arietinum and C. pinnatifidum was possible by hormoneaided pollinations, embryo rescue and tissue culture techniques to save aborting hybrid embryos.
