Development of the Sf-RNase Gene-Specific PCR Primer Set for Japanese Apricot (Prunus mume Sieb. et Zucc.)
PCR Japanese Apricot S-RNase
2009/7/13
Self-compatible cultivars of Japanese apricot (Prunus mume Sieb. et Zucc.) have a horticultural advantage over self-incompatible ones because no cross-pollinizer tree is required. Self-incompatibility...
Characterization of Fruit-Type Sucrose Synthase Gene Promoters Isolated from Tomato and Japanese Pear
promoter sucrose synthase
2010/3/4
We isolated the 5’ upstream promoter regions of the fruit-type sucrose synthase (SS) gene from tomato and Japanese pear by inverse PCR. The 5’ region of the tomato SS gene (TOMSSF) contained an intron...
