Establishment of Anthoceros agrestis as a model species for studying the biology of hornworts by Szövényi, P, Frangedakis, E, Ricca, M, Quandt, D, Wicke, S, Langdale, J

“…Phylogenetic analyses position a subset of charophyte algae as the sister group to land plants, and distinguish two land plant groups that diverged around 450 million years ago – the bryophytes and the vascular plants. Relationships between liverworts, mosses hornworts and vascular plants have proven difficult to resolve, and as such it is not clear which bryophyte lineage is the sister group to all other land plants and which is the sister to vascular plants. …”

The CAM lineages of planet Earth by Gilman, IS, Smith, JAC, Holtum, JAM, Sage, RF, Silvera, K, Winter, K, Edwards, EJ

“…<br><strong> Results and Conclusions<br></strong> We found direct evidence (in the form of experimental or field observations of gas exchange, day–night fluctuations in organic acids, carbon isotope ratios and enzymatic activity) for CAM in 370 genera of vascular plants, representing 38 families. Further assumptions about the frequency of CAM species in CAM clades and the distribution of CAM in the Cactaceae and Crassulaceae bring the currently estimated number of CAM-capable species to nearly 7 % of all vascular plants. …”

Conserved transport mechanisms but distinct auxin responses govern shoot patterning in Selaginella kraussiana. by Sanders, H, Langdale, J

“…To provide a comparative framework to understand the evolution of auxin regulation in vascular plants, the effect of perturbed auxin homeostasis was examined in the lycophyte Selaginella kraussiana. …”

Conserved transport mechanisms but distinct auxin responses govern shoot patterning in Selaginella kraussiana by Sanders, H, Langdale, J

“…To provide a comparative framework to understand the evolution of auxin regulation in vascular plants, the effect of perturbed auxin homeostasis was examined in the lycophyte Selaginella kraussiana. …”

Origin and diversification of basic-helix-loop-helix proteins in plants. by Pires, N, Dolan, L

“…Twenty of these subfamilies existed in the common ancestors of extant mosses and vascular plants, whereas six further subfamilies evolved among the vascular plants. …”

The evolution of root hairs and rhizoids. by Jones, V, Dolan, L

“…Root hairs form on the surface of roots of sporophytes (the multicellular diploid phase of the life cycle) in vascular plants. Rhizoids develop on the free-living gametophytes of vascular and non-vascular plants and on both gametophytes and sporophytes of the extinct rhyniophytes. …”

KNOX genes: versatile regulators of plant development and diversity. by Hay, A, Tsiantis, M

“…Knotted1-like homeobox (KNOX) proteins are homeodomain transcription factors that maintain an important pluripotent cell population called the shoot apical meristem, which generates the entire above-ground body of vascular plants. KNOX proteins regulate target genes that control hormone homeostasis in the meristem and interact with another subclass of homeodomain proteins called the BELL family. …”

Erosion of global functional diversity across the tree of life by Carmona, CP, Tamme, R, Pärtel, M, de Bello, F, Brosse, S, Capdevila, P, González, R, González-Suárez, M, Salguero-Gómez, R, Vásquez-Valderrama, M, Toussaint, A

“…Using trait and phylogenetic information for more than 75,000 species of vascular plants, mammals, birds, reptiles, amphibians, and freshwater fish, we characterized the global functional spectra of each of these groups. …”

Control of leaf and vein development by auxin. by Scarpella, E, Barkoulas, M, Tsiantis, M

“…Leaves are the main photosynthetic organs of vascular plants and show considerable diversity in their geometries, ranging from simple spoon-like forms to complex shapes with individual leaflets, as in compound leaves. …”

SCHIZORIZA controls tissue system complexity in plants. by Pernas, M, Ryan, E, Dolan, L

“…The formation of different tissue systems in multicellular organisms depends on the activity of groups of undifferentiated cells called stem cells. In vascular plants, the three principal tissue systems--dermal, ground, and vascular--are derived from specific groups of stem cells that are laid down during embryogenesis. …”

Multiple origins of dichotomous and lateral branching during root evolution by Hetherington, A, Berry, C, Dolan, L

“…Roots of extant vascular plants proliferate through lateral branching (euphyllophytes) or dichotomy (lycophytes)1–4. …”

New Guinea has the world's richest island flora by Cámara-Leret, R, Frodin, DG, Adema, F, Pannel, CM, Scotland, RW, Wood, JRI, Et al

“…So far, however, there has been no attempt to critically catalogue the entire vascular plant diversity of New Guinea. Here we present the first, to our knowledge, expert-verified checklist of the vascular plants of mainland New Guinea and surrounding islands. …”

CAM photosynthesis: the acid test by Winter, K, Smith, JAC

“…We show, in a survey encompassing 40 families of vascular plants, that nocturnal acidification is a feature entirely restricted to CAM species. …”

When is an invasive not an invasive? Macrofossil evidence of doubtful native plant species in the Galapagos Islands. by Coffey, E, Froyd, C, Willis, K

Recruitment and remodeling of an ancient gene regulatory network during land plant evolution. by Pires, N, Yi, K, Breuninger, H, Catarino, B, Menand, B, Dolan, L

“…Genetic and transcriptional analyses in loss of function A. thaliana and P. patens mutants suggest that the transcriptional interactions in the RSL kernel were remodeled and became more hierarchical during the evolution of vascular plants. We predict that other gene regulatory networks that control development in derived groups of plants may have originated in the earliest land plants or in their ancestors, the Charophycean algae.…”

Pattern in the root epidermis: An interplay of diffusible signals and cellular geometry by Dolan, L

“…Root epidermal development in vascular plants may be divided into three broad groups based on the mode of hair development; Type 1: any cell in the epidermis can form a tool hair; Type 2: the smaller product of an asymmetric cell division forms a root hair; Type 3: the epidermis is organized into discrete files of hair and non- hair cells. …”
