Self-incompatibility in Papaver
Self-fertilization, which results in reduced fitness of offspring, is a common problem in hermaphrodite angiosperms. To prevent this, many plants utilize self-incompatibility (SI), which is determined by the multi-allelic S locus, that allows discrimination between self (incompatible) and non-self (compatible) pollen by the pistil. In poppy (Papaver rhoeas), the pistil S-determinant (PrsS) is a...
متن کاملSelf-incompatibility
There are several different types of self-incompatibility in different flowering plant species, and there has recently been progress in understanding their molecular genetics by using combined molecular and evolutionary approaches. Questions include the mechanism of self-incompatibility (both the nature of the proteins encoded by the genes and whether incompatibility systems all have separate g...
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 کاملRecognizing self in the self-incompatibility response.
François Jacob once facetiously lamented the arrangement in the human body whereby reproduction is the only function for which an individual is equipped with only one-half of the necessary organs, thus entailing the expenditure of a substantial amount of time and energy into finding the other half (10). The spatial separation of the sexual partners (or organs) is indeed an obligatory feature of...
متن کاملGametophytic Self-Incompatibility in Petunia
Gametophytic self-incompatibility (GSI), which prevents growth of a pollen tube through the style, provides a means of preventing self-pollination. Seen in most eudicot plant families, GSI in the genus Petunia was described by Darwin in the 19th century. By the time the first edition of this monograph was published in 1984, nearly a century later, most of the readily observable phenomena associ...
