Occult polyclonality of preclinical pancreatic cancer models drives in vitro evolution

Nature Communications, 2022
It is unclear if the molecular profiles of pancreatic ductal adenocarcinoma (PDAC) preclinical models remain stable during propagation. Here, the authors characterise clonal evolution throughout propagation in PDAC cell lines and a patient-derived ...

Stability of Verticillium dahliae resistance in tissue culture-derived strawberry somaclones

Horticultural Science, 2015
Somaclonal variation is a novel source of useful traits in strawberry breeding. In our previous work we selected K40 clone from in vitro cultures of strawberry cv. Elsanta, which was characterized by high resistance to Verticillium dahliae. The objective

Clonal Propagation of Khaya senegalensis: The Effects of Stem Length, Leaf Area, Auxins, Smoke Solution, and Stockplant Age

International Journal of Forestry Research, 2011
Khaya senegalensis is a multipurpose African timber species. The development of clonal propagation could improve plantation establishment, which is currently impeded by mahogany shoot borer. To examine its potential for clonal propagation, the effects of

What drives the shift between sexual and clonal reproduction of Caragana stenophylla along a climatic aridity gradient?

BMC Plant Biology, 2018
Background The reasons that clonal plants shift between sexual and clonal reproduction have persisted as a knowledge gap in ecological literature. We hypothesized that clonal plants’ shifts between sexual and clonal reproduction in different environments

Evolution of almond genetic diversity and farmer practices in Lebanon: impacts of the diffusion of a graft-propagated cultivar in a traditional system based on seed-propagation

BMC Plant Biology, 2018
Background Under cultivation, many outcrossing fruit tree species have switched from sexual reproduction to vegetative propagation. Traditional production systems have persisted, where cultivar propagation is based on a mixed reproductive system.
