A light, scanning electron, and transmission electron microscopic study of pollen wall architecture in the subtribe Gnaphaliinae (Gnaphalieae, Asteraceae)
The pollen morphology and exine structure of 10 genera and 15 species of Gnaphaliinae were investigated using light, scanning electron, and transmission electron microscopy to better understand relationships within the Asteroideae and it is suggested that either Astereae, AstereAE-Anthemideae clade, or Heliantheae s.l.-Anthemides clade are the best candidates for the sister taxon/sister group of Gn Aphalieae.

An ITS phylogeny of tribe Senecioneae (Asteraceae) and a new delimitation of Senecio L.
Two phylogenies provide new insights into evolutionary relationships in Senecioneae and a new, monophyletic, delimitation of Senecio are proposed, resulting in a first approximation of a comprehensive phylogeny for the tribe. Expand
Molecular phylogeny and biogeography of the Qinghai-Tibet Plateau endemic Nannoglottis (Asteraceae).
It is found that all sampled species of Nannoglottis are a well-defined monophyly, and the molecular infragenetic phylogeny of the genus identifies two distinct clades, which reject the earlier infrageneric classification based on the arrangement of the involucral bracts and the length of the ligules, but agree well with the habits and ecological preferences of its current species.

tRNALeu intron ( UAA ) of Ficus carica L . : genetic diversity and evolutionary patterns
Cytoplasmic chloroplast DNA was explored to establish genetic relationships among Ficus carica cultivars and elucidate the molecular evolution of the species. The results suggest the occurrence ofExpand
A new look at water transport regulation in plants.
A new theoretical framework describing plant responses to drying soil, based on the relationship between midday and predawn leaf water potentials is developed, which offers a new way of characterizing water transport regulation in plants that can be used to assess their vulnerability to drought under current and future climatic conditions.

Self-Organizing Maps as a New Tool for Classification of Plants at Lower Hierarchical Levels
The study shows that SOM applied to chemical data can contribute to differentiate genera, subtribes, and groups of subtribes (subtribe branches), as well as to tribal and subtribal classifications of Heliantheae, exhibiting a high hit percentage comparable to that of an expert performance. Expand
ITS secondary structure derived from comparative analysis: implications for sequence alignment and phylogeny of the Asteraceae.
The sequence alignment enabled by conserved structural features provides a framework for broadscale molecular evolutionary studies and the first family-level phylogeny of the Asteraceae based on nuclear DNA data, which shows considerable congruence with relationships among major lineages of the family suggested by chloroplast DNA studies.

A phylogenetic reconsideration of the pollen starch-pollination correlation.
This work assembled a database of 207 plant species for which starchiness of pollen and pollination mode are known, organized these species into a phylogeny based on published cladograms and tested three hypotheses concerning the concordance of pollen starch. Expand
Phylogeny of South African Gnaphalieae (Asteraceae) based on two noncoding chloroplast sequences.
A phylogeny of the South African Gnaphalieae is reconstructed using sequence data from two noncoding chloroplast DNA sequences, thetrnL intron and trnL/trnF intergenic spacer to show general agreement between the molecular analysis and that of morphology. Expand
A reassessment of tribal affinities of the enigmatic genera Printzia and Isoetopsis (Asteraceae), based on three chloroplast sequences
Phylogenetic analysis indicates that both Printzia and Isoetopsis have a strong affinity with members of the tribe Astereae. Expand
