Vegetative and generative maintenance of self-incompatibility in six accessions of German chamomile
Self-incompatible (SI) plants are able to form ideal mother lines for hybrid crossing in hermaphroditic plants, assuring fertilization from the desired father line. To find out suitable ways to maintain SI was the aim of this study. Among 220 plants of German chamomile (Matricaria recutita (L.) Rauschert) within six accessions SI-genotypes were selected. SI was determined as staying seedless in...
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 کاملEvolution of self-incompatibility:
Whitehouse (1950): 1. Sudden rise of angiosperms during the Cretaceous period (144-65 million years ago) was due to the development of barriers for self-pollination forcing the flowering plants to out breed and resulted genetic variations and rapid expansion of the angiosperms. 2. 70% of the angiosperms are hermophrodite species, while no more than 5% dioecious. Such a high proportion of hermop...
متن کاملGenetic Variation of Lime (Citrus sp.) Accessions Using Flow Cytometry Technique, Morphological Characteristics and Molecular Markers
Because of sexual propagation of Mexican lime in southern regions of Iran, there are many lime accessions (lime biotypes) in Mexican lime gardens in which appear some variation in fruit and tree shape. However, most of these accessions are susceptible to witches broom disease of lime (WBDL). Persian lime (C. latifolia Tanaka) is a triploid WBDL-tolerant species. Considerable number of un-descri...
متن کاملActin senses self-incompatibility
A ctin depolymerization is a death trigger for poppy pollen, according to Thomas et al. (page 221), that prevents self-fertilization. Some plants prefer not to be fertilized by pollen grains that are genetically similar to themselves. These plants express self-incompatibility (S) proteins. A match between the pistil’s S-proteins and the pollen’s S-allele triggers a rapid calcium infl ux, actin ...
