Wood Anatomy of Crossosomatales: Patterns of Wood Evolution with Relation to Phylogeny and Ecology [PDF]
The seven families hypothesized by Sosa and Chase to comprise Crossosomatales possess relatively long vessel elements with scalariform perforation plates and scalariform to opposite vessel-ray pitting; tracheids; diffuse axial parenchyma; and ...

Abstract The species boundaries in Hypochaeris sect. Seriola (Asteraceae, Cichorieae) are difficult to establish due to the phenotypic similarity between taxa. The main objective of the present study was to characterize the phylogenetic position of the annual Hypochaeris achyrophorus using plastid and nuclear DNA markers, and to determine whether some ...

Molecular Phylogenetics of Phyllanthaceae: Evidence from Plastid MatK and Nuclear PHYC Sequences [PDF]
Plastid matK and a fragment of the low-copy nuclear gene PHYC were sequenced for 30 genera of Phyllanthaceae to evaluate tribal and generic delimitation.

Repeated shifts out of tropical climates preceded by whole genome duplication
Summary While flowering plants have diversified in virtually every terrestrial clime, climate constrains the distribution of individual lineages. Overcoming climatic constraints may be associated with diverse evolutionary phenomena including whole genome duplication (WGD), gene‐tree conflict, and life‐history changes.

Research efforts in plant biology have often been focused on sequenced and well‐studied ‘model’ organisms. Despite the advent of relatively inexpensive genome sequencing, most plant taxonomic groups are underrepresented, with few species that ‘represent’ the diversity of whole genera.

Floral structure and systematics in four orders of rosids, including a broad survey of floral mucilage cells [PDF]
Phylogenetic studies have greatly impacted upon the circumscription of taxa within the rosid clade, resulting in novel relationships at all systematic levels. In many cases the floral structure of these taxa has never been compared, and in some families,

Surveying Rubisco diversity and temperature response to improve crop photosynthetic efficiency. [PDF]
The threat to global food security of stagnating yields and population growth makes increasing crop productivity a critical goal over the coming decades.

Environmental DNA sampling coupled with high‐throughput sequencing is increasingly recognized as a useful method for assessing biodiversity with potential applications in terrestrial environments. Rock pools on granite inselbergs support diverse aquatic communities, yet the application of eDNA to document their biodiversity is lacking.

Abstract Generalist plant‐feeding insects are characterised by a broad host repertoire that can comprise several families or even different orders of plants. The genetic and physiological mechanisms underlying the use of such a wide host range are still not fully understood.
