Cytoplasmic‐Genic Male‐Sterility in Interspecific Matings of Cajanus

Use of flow cytometry, fluorescence microscopy, and PCR-based techniques to assess intraspecific and interspecific matings of Armillaria species

Restriction in Matings of Escherzchza Coli

RESTRICTION in Escherichia coli limits the acceptance of genetic elements such as bacteriophage, sex-factor, and donated bacterial chromosome. These extrinsic genetic elements carry a specificity determined by their last host. When the specificity differs from that of the new potential host, the genetic element is restricted by the new host cell. Restriction is manifest by low efficiency of pla...

Forced Matings in Natural Populations of Drosophila.

Forced mating has been reported for a number of vertebrate and invertebrate taxa. The implications of forced copulation for mating system evolution, however, has received the greatest consideration for birds (Gowaty and Buschhaus 1998). Insect species in which females mate before full maturation represent a different slant on forced mating. Some lepidoptera, for example, exhibit the unusual phe...

Genetic Patterns of Domestication in Pigeonpea (Cajanus cajan (L.) Millsp.) and Wild Cajanus Relatives

Pigeonpea (Cajanus cajan) is an annual or short-lived perennial food legume of acute regional importance, providing significant protein to the human diet in less developed regions of Asia and Africa. Due to its narrow genetic base, pigeonpea improvement is increasingly reliant on introgression of valuable traits from wild forms, a practice that would benefit from knowledge of its domestication ...

Newton maps as matings of cubic polynomials

In this paper we prove existence and uniqueness of matings of a large class of renormalizable cubic polynomials with one fixed critical point and the other cubic polynomial having two fixed critical points. The resulting mating is a Newton map. Our result is the first part towards a conjecture by Tan Lei, stating that all (cubic) Newton maps can be described as matings or captures.
