Genetics 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 کاملCloning of cDNA for a cell wall-bound acid invertase from tomato (Lycopersicon esculentum) and expression of soluble and cell wall-bound invertases in plants and wounded leaves of L. esculentum and L. peruvianum.
A cDNA, Wiv-1, for an isozyme of acid invertase (EC 3.2.1.26) was cloned from wounded leaves of tomato (Lycopersicon esculentum). The encoded protein had a basic isoelectric point and strong similarity to the amino acid sequences of plant cell wall-bound invertases. The conserved sequence WECPD that is found in all plant cell wall-bound invertases was also found in the deduced protein. These re...
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 کاملGenetic control and evolution of sesquiterpene biosynthesis in Lycopersicon esculentum and L. hirsutum.
Segregation analysis between Lysopersicon esculentum (cultivated tomato) and L. hirsutum (wild form) in conjunction with positional verification by using near-isogenic lines demonstrated that biosynthesis of two structurally different classes of sesquiterpenes in these species is controlled by loci on two different chromosomes. A locus on chromosome 6, Sesquiterpene synthase1 (Sst1), was identi...
متن کاملEnumeration of Culturable Endophytic Bacterial Population of Different Lycopersicum esculentum L. Varieties
Endophytes are the microbes, which reside inside the plants without causing any harm. They colonize the internal plant tissues and form a different range of interaction including symbiotic and trophobiotic. Such bacteria promote plant growth and also act as biocontrol agents. In some cases endophytes also applied as biological agents like nanoparticles in controlling human diseases including ca...
