Abstract Polyploid organisms are eukaryotes that have more than two complete sets of chromosomes (one from each parent or ancestor) in somatic and germline cells of animals, fungi, and plants. Polyploidy of individual cells…

Chromosomal evolution in Brachiaria forage grasses with Fabiola Carvalho Santos
Fabiola Santos from University of Londrina, Brazil, is working on the Chromosomal evolution and the organization of repetitive DNA sequences in diploid and polyploid Brachiaria forage grasses in the molecular cytogenetics group in Leicester. Brachiaria is most important cultivated forage grass genus in Brazil (with billion-dollar production), and the genus includes diploid and polyploid species with similar…

Nouf Alsayied: PhD student with Saffron Crocus at the University of Leicester and faculty member Umm Al-Qura University, Kingdom of Saudi Arabia
My research focuses on understanding the origin and diversity of the genus Crocus (Iridaceae), with particular emphasis on a triploid sterile plant, Crocus sativus (2n=3x=24) that yields Saffron, one of the most expensive spices on earth. The saffron is the stigmas of the flowers, and nearly 200,000 must be collected to give 1kg of spice,…
