Chromosome number variation in somatic hybrids between transgenic tomato (Lycopersicon esculentum) and Solanum lycopersicoides.
Leaf mesophyll protoplasts of Lycopersicon esculentum were fused with suspension-culture-derived protoplasts of Solanum lycopersicoides by a PEG treatment. Both species have the same chromosome number (2n = 2x = 24). The hybrid calli were selected using the full selection method - kanamycin resistance and culture conditions critical for L. esculentum protoplast divisions. The genomic in situ hy...
متن کاملMeiosis in sesquidiploid hybrids of Lycopersicon esculentum and Solanum lycopersicoides.
We have synthesized diploid hybrids between Lycopersicon esculentum and Solanum lycopersicoides and have converted them to allotetraploids. Two sesquidiploids, having two complements of the former parent and one of the latter, have been obtained by backcrossing the former parent with the alloploid. In meiosis of the sesquidiploid the L. esculentum chromosomes exhibit strong preferential pairing...
متن کاملGenetics of hybrid incompatibility between Lycopersicon esculentum and L. hirsutum.
We examined the genetics of hybrid incompatibility between two closely related diploid hermaphroditic plant species. Using a set of near-isogenic lines (NILs) representing 85% of the genome of the wild species Lycopersicon hirsutum (Solanum habrochaites) in the genetic background of the cultivated tomato L. esculentum (S. lycopersicum), we found that hybrid pollen and seed infertility are each ...
متن کاملProteomic analysis of tomato (Lycopersicon esculentum) pollen.
In flowering plants, pollen grains are produced in the anther and released to the external environment with the primary function of delivering sperm cells to the female gametophyte. This study was conducted to identify proteins in tomato pollen and to analyse their roles in relation to pollen function. Tomato is an important crop which is grown worldwide and is an excellent experimental system....
متن کاملThe Inheritance of Self-Incompatibility in Hybrids of Lycopersicon Esculentum Mill. x L. Chilense Dun.
OTH self-fertile and self-incompatible species are found in the genus BLycopersicon (LAMM 1950). The self-incompatibility in L. peruuianum was shown to be of the Nicotiana or multiple-allelic gametophytic type by MCGUIRE and RICK (1954). Less extensive evidence suggested similar genetic control in L. hirsutum, L. glandulosum, and L. chilense (L. peruvianum f . dentatum) . I n addition, the inhe...
