Citrus: Genetics, Breeding and Biotechnology

Citrus breeding, genetics and genomics in Japan

Citrus is one of the most cultivated fruits in the world, and satsuma mandarin (Citrus unshiu Marc.) is a major cultivated citrus in Japan. Many excellent cultivars derived from satsuma mandarin have been released through the improvement of mandarins using a conventional breeding method. The citrus breeding program is a lengthy process owing to the long juvenility, and it is predicted that mark...

Genetics then and now: breeding the best and biotechnology.

In the past, domesticated animals were genetically improved by identifying meritorious individuals, mating animals displaying desired traits, continued breeding of related animals to perpetuate their superior traits and crossbreeding when inbreeding depression became evident. Today, assisted reproduction and biotechnology allow breeders to design and direct the reproductive course, disseminate ...

Genetics: Breeding and Genetics

In broilers, heat stress results in reduced feed intake, digestion inef­ ficiency, impaired metabolism, and death. Our objective was to initiate a study on the effects of heat stress by profiling the transcriptome of a metabolically active organ, the liver, from heat-stressed and non-heat­ stressed broilers. From 21 to 28 d of age, heat-stressed broilers were exposed to daily 7-h cycles of 35°C...
