Life history theory predicts that plants in adverse environments for juvenile performance start reproduction at a smaller size and exhibit higher reproductive allocation compared to their counterparts in more favourable environments. Merinero et al. explore the reproductive strategy of an asexually reproducing lichen along a rainfall gradient.
Consistent with the predictions of life-history theory, they find a decrease in the size for reproduction, and a higher reproductive allocation in drier, adverse, environments. By focusing on an asexually reproducing lichen, the study improves our understanding of life history diversity and reproductive strategies across environments.
Jatropha curcas could be an oil crop with major biofuel potential, but the breeding germplasm has little variation. Botanists have found that there is genetic potential in previously overlooked non-toxic jatropha, but it needs conservation.
What is it that makes a plant get up and stay up? A new review looks at the creation of secondary cell walls. These microscopic features are the key to understanding the architecture of the plants we see around us.
