Many Caryophyllales species also have betalain pigmentation and medullary bundles, both of which have been linked to stress tolerance, albeit with less precise functional characterisation.

We also show that the evolution of succulence and medullary bundles is favoured in betalain\u2010pigmented lineages. However, medullary bundles, unlike succulence, do not show a clear relationship with drought conditions.<\/jats:p>\n                      <\/jats:list-item>\n                      <jats:list-item>\n                        <jats:p>The evolution of betalains is likely to have enabled Caryophyllales to adapt to and survive stressful conditions, including drought.
