Let’s pluck the daisy: dissection as a tool to explore the diversity of Asteraceae capitula

Abstract Asteraceae, the daisy family, are one of most diverse families angiosperms and predominant in many ecosystems, including grasslands, deserts, savannas high-elevation mountains. They characterized by a peculiar inflorescence, capitulum, which mimics flower, but is actually made up tightly grouped florets. The capitulum considered key character underpinning impressive evolutionary success it plays pivotal role economic importance given that species cultivated for their agricultural horticultural purposes. However, to date, there still no comprehensive understanding extent morphological diversity capitula across lineages Asteraceae. This mainly due lack appropriate tools describing such complex condensed structure. To address problem, we present protocol characterizing full from any lineage involves making whole dissection fresh material; simple cost-effective requires relatively easy-to-transport equipment meaning can be done during fieldwork.
