Genome size variation among common dandelion accessions informs their mode of reproduction and suggests the absence of sexual diploids in North America
Apomixis is the ability of plants to produce asexual seeds, which are clones of the mother plant. The phenomenon of apomixis is tightly linked to ploidy, where diploids lack apomixis and reproduce sexually, wh...

Low light and low ammonium are key factors for guayule leaf tissue shoot organogenesis and transformation
A new method has been developed for guayule tissue culture and transformation. Guayule leaf explants have a poor survival rate when placed on normal MS medium and under normal culture room light conditions. Lo...

Visualization of the Malleability of the Rubber Core of Rubber Particles from Parthenium argentatum Gray and Other Rubber-Producing Species Under Extremely Cold Temperatures
Rubber particles from Parthenium argentatum Gray (guayule) were frozen in liquid nitrogen (−196°C), fractured, and visualized using cryo-scanning electron microscopy. We observed that the rubber polymer core of t...
