Domestication, polyploidy and genomics of crops and weeds PAGXXV
Plant and Animal Genome Conference in San Diego #PAGXXV each January is the chance to join 3500 people working in genomics. I presented a talk on the molecular cytogenetics group’s work, starting with consideration of early stages of crop domestication, and then thinking about how we can make agriculture more sustainable. I also considered weeds,…

Needs for understanding water and food security
“The earth’s land surface receives about 110,000 km3 of rainfall annually. More than half of this water is evapotranspired (transmitted from soils and through plants to the air); about 20,000 km3 falls on land that is cultivated in some form; and about 40,000 km3 becomes available in dams, lakes, rivers, streams and aquifers for human…

Wheat-Thinopyrum introgression work wins prize for Niaz Ali, Hazara, Pakistan
Dr Niaz Ali, Hazara University, Mansehra, Pakistan works on the introgression of characters from alien species into wheat, having completed his PhD in Leicester in 2012 with Dr Trude Schwarzacher. He presented his PhD work at the Annual Meeting of the Society for Experimental Biology (SEB http://www.sebiology.org/meetings /Valencia/Programmes.html) in the session on Exploiting genetic diversity for…
Dr Ijaz Rasool Noorka – Collaborator from University of Sargodha, Pakistan and Visiting Research Fellow
Dr Ijaz Rasool Noorka has broad interests in the development of productive and sustainable agriculture for Pakistan and developing countries. His interests complement those of the Molecular Cytogenetics Group, and have enabled us to extend our consideration of the outcomes and impact of our work on exploitation of biodiversity by chromosome engineering. Ijaz has been…
Superdomestication, feed-forward breeding and climate proofing crops
Climate Proofing of Food Crops, through genetic improvement for adaptation, is an important, medium-term, objective to ensure food-security and increase production while enhancing the sustainability of agriculture. The IAEA has a Coordinated Research Project discussing this topic (archive version). In the YouTube video here, I discuss some of the challenges plant researchers are addressing, and…
Alien chromosome introgression transferring characters into bread wheat
In situ hybridization is now widely used to identify the nature and size of chromosome, chromosome arm and chromosome segment introgressions from alien or wild species in plant breeding lines. The molecular cytogenetics research group has several projects investigating introgression of chromosomes into wheat from rye, Thinopyrum (2x and 6x), Aegilops and other species or…
