Gametophytic self-incompatibility in Andean capuli (Prunus serotina subsp. capuli): allelic diversity at the S-RNase locus influences normal pollen-tube formation during fertilization [PDF]
Capuli (Prunus serotina subsp. capuli) is a tree species that is widely distributed in the northern Andes. In Prunus, fruit set and productivity appears to be limited by gametophytic self-incompatibility (GSI) which is controlled by the S-Locus.

Breakdown of self-incompatibility has frequently been attributed to loss-of-function mutations of alleles at the locus responsible for recognition of self-pollen (i.e. the S-locus). However, other potential causes have rarely been tested.

Segmental Translocation Contributed to the Origin of the Brassica S-locus
Self-incompatibility (SI), which has recurred during the evolution of plants, is one of the most important cross-pollination mating systems. Three S-loci have been reported in Brassicaceae, namely, Arabidopsis lyrata (Al), Brassica (Br), and ...

Independent S-locus mutations caused self-fertility in Arabidopsis thaliana. [PDF]
A common yet poorly understood evolutionary transition among flowering plants is a switch from outbreeding to an inbreeding mode of mating. The model plant Arabidopsis thaliana evolved to an inbreeding state through the loss of self-incompatibility, a ...

Recent and Ancient Signature of Balancing Selection around the S-Locus in Arabidopsis halleri and A. lyrata [PDF]
Balancing selection can maintain different alleles over long evolutionary times. Beyond this direct effect on the molecular targets of selection, balancing selection is also expected to increase neutral polymorphism in linked genome regions, in inverse ...

A nonS-locus F-box gene breaks self-incompatibility in diploid potatoes
Diploid potatoes are typically self-incompatible, complicating efforts to breed diploid cultivars. Here the authors report map-based cloning of the S-locus inhibitor (Sli) gene in potato which encodes a non S-locus F-box protein that is expressed in ...

The women´s body like locus of oppression/repression
Considering Simone de Beauvoir's conceptualization of the body as a situation, and the sociocultural fact that women -as a human group- are oppressed/repressed in all societies, the paper underlines: a) how the woman's body is considered an object for ...

Mapping of panda plumage color locus on the microsatellite linkage map of the Japanese quail
Background Panda (s) is an autosomal recessive mutation, which displays overall white plumage color with spots of wild-type plumage in the Japanese quail (Coturnix japonica).
