The internal transcribed spacer (ITS) region of the nuclear rDNA cistrons is one of the more
frequently utilized regions for phylogenetic analyses at the genus and species levels. It has …

ABSTRACT Isoprene (2‐methyl‐1, 3‐butadiene) is emitted from many plants and it appears
to have an adaptive role in protecting leaves from abiotic stress. However, only some …

• Premise of the study: Recent analyses employing up to five genes have provided
numerous insights into angiosperm phylogeny, but many relationships have remained …

Growing evidence of morphological diversity in angiosperm flowers, seeds and pollen from
the mid Cretaceous and the presence of derived lineages from increasingly older geological …

Phylogenetic analysis of 330 plastid matK gene sequences, representing 235 genera from
37 of 39 tribes, and four outgroup taxa from eurosids I supports many well‐resolved …

The pantropical Zingiberaceae is the largest family in the order Zingiberales with 53 genera
and over 1200 species. Classifications of the family first proposed in 1889 and refined by …

Pollen ranges from 2.5% to 61% protein content. Most pollen proteins are likely to be
enzymes that function during pollen tube growth and subsequent fertilization, but the vast …

Although temporal calibration is widely recognized as critical for obtaining accurate
divergence-time estimates using molecular dating methods, few studies have evaluated the …

Recent models and analyses of paleoecological records suggest that tree populations are
capable of rapid migration when climate warms. Fossil pollen is commonly interpreted as …
