The Inheritance of Unilateral Incompatibility in Lycopersicon Hirsutum.
A M O N G the mechanisms restricting the flow of genes between discrete populations of plants, unilateral incompatibility (UI) is unique in that one of the reciprocal crossing combinations succeeds whereas the other fails. The term unilateral incompatibility is generally restricted to a phenomenon thought to be closely related to self-incompatibility (SI), for it occurs in matings of self-ferti...
متن کاملComparative sequencing in the genus Lycopersicon. Implications for the evolution of fruit size in the domestication of cultivated tomatoes.
Sequence variation was sampled in cultivated and related wild forms of tomato at fw2.2--a fruit weight QTL key to the evolution of domesticated tomatoes. Variation at fw2.2 was contrasted with variation at four other loci not involved in fruit weight determination. Several conclusions could be reached: (1) Fruit weight variation attributable to fw2.2 is not caused by variation in the FW2.2 prot...
متن کاملDissecting the genetic pathway to extreme fruit size in tomato using a cross between the small-fruited wild species Lycopersicon pimpinellifolium and L. esculentum var. Giant Heirloom.
In an effort to determine the genetic basis of exceptionally large tomato fruits, QTL analysis was performed on a population derived from a cross between the wild species Lycopersicon pimpinellifolium (average fruit weight, 1 g) and the L. esculentum cultivar var. Giant Heirloom, which bears fruit in excess of 1000 g. QTL analysis revealed that the majority (67%) of phenotypic variation in frui...
متن کاملAnalysis of the molecular size of tomato (Lycopersicon esculentum Mill) fruit polyuronides by gel filtration and low-speed sedimentation equilibrium.
The cell-wall structures of tomato (Lycopersicon esculentum Mill) and other fruit are intimately linked with the nature of their polyuronides. Cell-wall polyuronides from unripe and ripe tomato fruit were isolated and purified and their molecular size and molecular-size distributions were compared. It was demonstrated that there is a considerable decrease in the weight-average Mr upon ripening ...
متن کاملInheritance of tooth size in Liverpool families.
more fully the inheritance of tooth size in British families. Though twin studies have established a high genetic component in tooth size (Lundstrom, 1948; Osborne, Horowitz, and De George, 1958), few family studies have been undertaken to elucidate the matter further. The studies of Hohl (1934) and Martin (1934) were among the first but used relatively small samples. They calculated both paren...
