Synonymy, sampling and seed plant numbers by Wortley, A, Scotland, R

How many species of seed plants are there? by Scotland, R, Wortley, A

“…Recent estimates of the number of described species of seed plant have varied by as much as 62%. The underlying methodology of these estimates is characterised and discussed. …”

Symbiont switching and alternative resource acquisition strategies drive mutualism breakdown by Werner, G, Cornelissen, J, Cornwell, W, Soudzilovskaia, N, Kattge, J, West, S, Kiers, E

“…By using a comparative approach, we identify ∼25 independent cases of complete mutualism breakdown across global seed plants. We found that breakdown of cooperation was only stable when host plants (i) partner with other root symbionts or (ii) evolve alternative resource acquisition strategies. …”

Early evolution of bHLH proteins in plants. by Pires, N, Dolan, L

“…Most of the bHLH subfamilies present in seed plants such as Arabidopsis thaliana and Oryza sativa are also present in early diverging groups of land plants, including mosses and lycophytes. …”

The evolution of land plant cilia by Hodges, M, Wickstead, B, Gull, K, Langdale, J

“…Land plants provide an excellent system for the investigation of cilia evolution and loss across a broad phylogeny, because early divergent land plant lineages produce cilia, whereas most seed plants do not. This review highlights the differences in cilia form and function across land plants and discusses how recent advances in genomics are providing novel insights into the evolutionary trajectory of ciliary proteins. …”

Ferns the missing link in shoot evolution and development by Langdale, J, Plackett, A, DiStilio, V

“…As sister group to the seed plants, the monilophytes (ferns and relatives) represent an excellent phylogenetic midpoint of comparison for unlocking the evolution of shoot developmental mechanisms, and recent technical advances have finally made transgenic analysis possible in the emerging model fern Ceratopteris richardii. …”

Negative regulation of KNOX expression in tomato leaves. by Jasinski, S, Kaur, H, Tattersall, A, Tsiantis, M

“…Leaves of seed plants can be described as simple, where the leaf blade is entire, or dissected, where the blade is divided into distinct leaflets. …”

Growth-survival trade-offs and allometries in rosette-forming perennials by Metcalf, C, Rees, M, Alexander, J, Rose, K

“…The pattern of biomass partitioning was compared with the predictions of Enquist and Niklas (2002a) Global allocation rules for patterns of biomass partitioning in seed plants. Science 295, 1517-1520. In agreement with their predictions, the overall relationship between above- and below-ground biomass was isometric. …”

High-efficiency stable transformation of the model fern species Ceratopteris richardii via microparticle bombardment. by Plackett, A, Huang, L, Sanders, H, Langdale, J

“…Ferns represent the most closely related extant lineage to seed plants. The aquatic fern Ceratopteris richardii has been subject to research for a considerable period of time, but analyses of the genetic programs underpinning developmental processes have been hampered by a large genome size, a lack of available mutants, and an inability to create stable transgenic lines. …”

Long-proboscid flies as pollinators of cretaceous gymnosperms by Peñalver, E, Arillo, A, Pérez-De La Fuente, R, Riccio, M, Delclòs, X, Barrón, E, Grimaldi, D

“…Evidence is thus now gathering that visitors and probable pollinators of early anthophytes, or seed plants, involved some insects with highly specialized morphological adaptations, which has consequences for interpreting the reproductive modes of Mesozoic gymnosperms and the significance of insect pollination in angiosperm success.…”

PROCERA encodes a DELLA protein that mediates control of dissected leaf form in tomato. by Jasinski, S, Tattersall, A, Piazza, P, Hay, A, Martinez-Garcia, J, Schmitz, G, Theres, K, McCormick, S, Tsiantis, M

“…Leaves of seed plants can be described as simple, where the leaf blade is entire, or dissected, where the blade is divided into distinct leaflets. …”

Conservation of ciliary proteins in plants with no cilia. by Hodges, M, Wickstead, B, Gull, K, Langdale, J

“…However, cilia have also been lost multiple times in different lineages, with at least two losses occurring within the land plants. Whereas all non-seed plants produce cilia for motility of male gametes, some gymnosperms and all angiosperms lack cilia. …”

Investigating chlorsulfuron toxicity and resistance in the liverwort Marchantia polymorpha by Casey, A

“…I show that the 71 and 72 clans and Tau and Phi classes arose before the evolution of land plants and rapidly expanded in seed plants.</p> <p>Using RNA-Seq and over-expression constructs I show that a 71 clan CYP up-regulated by the herbicide chlorsulfuron in the liverwort Marchantia polymorpha conferred a low level of resistance to chlorsulfuron when over-expressed. …”

Completing the global inventory of plants – species discovery and diversity by Goodwin, ZA

“…This ambitious target set by the Global Strategy for Plant Conservation is hampered by two facts; first, many species of seed plant remain poorly known and second, the process of improving taxonomy and discovering species is not well understood. …”

Plant growth rates and seed size: a re-evaluation. by Turnbull, L, Philipson, C, Purves, D, Atkinson, R, Cunniff, J, Goodenough, A, Hautier, Y, Houghton, J, Marthews, T, Osborne, C, Paul-Victor, C, Rose, K, Saner, P, Taylor, S, Woodward, F, Hector, A, Rees, M

“…Small-seeded plant species are often reported to have high relative growth rate or RGR. …”

Repression of apical homeobox genes is required for embryonic root development in Arabidopsis. by Grigg, S, Galinha, C, Kornet, N, Canales, C, Scheres, B, Tsiantis, M

“…Development of seed plant embryos is polarized along the apical-basal axis. …”
