Studies on Self-Sterility VII. Heredity and Selective Pollen-Tube Growth.
A new genetic interpretation of self-sterility as manifested in Sicotiana alata Lk. and Otto var. grandijiora Comes and Sicotiana forgetiana Hort. (Sand.), or their hybrids, has been proposed recently (EAST and M ~ N G E L S DORF 192.5). The detailed evidence on which this interpretation rests i< given in the present paper. Self-sterility appears to behave as a simple recessive when the,e speci...
متن کاملSuperiority of Pollen from Fl Plants of Maize in Selective Fertilization
Many studies on selective fertilization in maize, Zea mays L., have been reported since it was detected that genetic factor (s) linked to the de gene is responsible for distortion of segregation in F 2.2> On the other hand, some applications of the selective fertilization to maize breeding, i.e. prediction for combining abi lity of inbred lines or F1 seed production without using cytoplasmic ma...
متن کاملFollicle cell proteasome activity and acid extract from the egg vitelline coat prompt the onset of self-sterility in Ciona intestinalis oocytes.
In the hermaphrodite ascidian Ciona intestinalis, the egg vitelline coat (VC) controls gamete self-nonself discrimination. Oocytes, after germinal vesicle breakdown, can be fertilized by both self and nonself sperm. However, a barrier to fertilization by self sperm progressively develops in the VC in the 3 hours after germinal vesicle breakdown. During this period, follicle cells attached to th...
متن کاملThe hsp70 protein is involved in the acquisition of gamete self-sterility in the ascidian Ciona intestinalis.
In the hermaphrodite ascidian Ciona intestinalis, gamete self-incompatibility is a mechanism that prevents self-fertilization and is based on the ability of the oocyte vitelline coat to distinguish and accept only heterologous spermatozoa. The onset of self-sterility occurs during oogenesis and involves or is controlled by the follicle cells. Gamete self-nonself discrimination, a process that c...
متن کاملAllorecognition mechanisms during ascidian fertilization.
Ascidians (primitive chordates) are hermaphroditic animals, releasing sperm and eggs nearly simultaneously. But, many ascidians, including Ciona intestinalis and Halocynthia roretzi, show self-sterility or preference for cross-fertilization rather than self-fertilization. The molecular mechanisms underlying this allorecognition process are only poorly understood. We recently identified the gene...
