The most important tropical forages are Brachiaria spp. Existing cultivars are natural, polyploid, aposporous apomicts. Breeding programs seek to combine attributes from the tetraploid apomicts B. brizantha and B. decumbens. Apomixis is monogenic and dominant. We sought to synthesize an allogomous, sexual, breeding population containing germplasm from selected apomicts. Apospory was not detected in a large open-pollinated progeny of sexual hybrids from sexual-by-apomictic crosses.  2, record 8, English, - apospory

Polyploidy can be induced with colchicine, an alkaloid of the meadow saffron (Colchicum autumnale) that inhibits mitosis ... It hampers the development of the nuclear spindle. A mitosis that takes place after treatment with colchicin is called a C-mitosis. It enables an easier detection and identification of chromosomes than a normal mitosis does.  2, record 14, English, - c%2Dmitosis

In a polyploid derivative of an interspecific hybrid each parental chromosome is represented twice(amphidiploid) or one genome occurs twice and the other only once(sesquidiploid). So there is a choice of pairing between homologous chromosomes(autosyndesis) or homologous chromosomes(allosyndesis). For estimating the amount of allosyndesis in a polyploid derivative of an interspecific hybrid, allosyndetic bivalents should also be taken into consideration in addition to multivalents.  2, record 17, English, - allosyndesis

My research interests may broadly be defined as encompassing both "pattern" and "process" aspects of plant evolutions. The former includes phylogenetic analyses of both organisms and molecules, while the latter involves efforts to develop increased understanding of interspecific introgression and speciation mechanisms, especially polyploidy. A large part of my effort involves the genus Gossypium(cotton), which provides model systems for approaching several objectives. Polyploid speciation is a conspicuous and important process of plant evolution, yet we know relatively little about genetic and genomic processes that accompany polyploidization.  1, record 19, English, - polyploidization
