Meiosis 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 کاملChromosome 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 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...
متن کاملPreferential Chromosome Pairing in Allotetraploid Lycopersicon Esculentum-solanum Lycopersicoides.
large and diverse body of data argues that chromosomes are longitudinally A differentiated in such a way that corresponding segments located in different chromosomes are able to recognize and synapse with each other with a high degree of precision at meiotic prophase; this property is termed “homology.” Although regions exhibiting homology may not be coiitinuous throughout the length of a chrom...
متن کاملIn vitro flowering and fruiting in tomato (Lycopersicon esculentum Mill.)
In vitro flowering and fruiting were induced in plants regenerated from calli of leaf explants of Lycopersicon esculentum var. Pant 11. MS medium supplemented with 2 mg/l BAP displayed the best response followed by MS with 2 mg/l BAP, 1 mg/ l ABA and 0.5 mg/l IAA. Flower buds were developed both directly from callus and regenerated plantlets from leaf explants under 16 h (39.3 μmol m-2s-1) phot...
