this study performed to evaluate genetic diversity of some wild and domesticated (unknown foreign cultivars) blackberries in sanru collection based on morphological traits. results showed high diversity for flowering, ripening time and fruit juice. wild genotypes showed significant differences in leaf, flower, thorn number, fruits and seed fresh weight compared to domesticated cultivars. based ...

Tobacco sperm cells contain intact mitochondria within their nuclei with a frequency of 0.35 [plusmn] 0.13 per cell. These inclusions appear to originate from mitochondria found among chromatids in the highly elongated metaphase plate of the dividing generative cell. These organelles are apparently captured during the reconstitution of the nuclear envelope. Only sperm cells were observed to con...
