Lithochloron, a new genus of green algae residing in coral skeleton (Cladophorales, Chlorophyta)

open access: yesJournal of Phycology, EarlyView.
Abstract Coral skeletons host diverse microbial communities, including endolithic green algae that contribute to holobiont functioning. The siphonous green alga Ostreobium (Bryopsidales) is arguably the best‐known coral endolith, but recent environmental sequencing has indicated that other lineages of green algae may also inhabit the coral skeleton ...

Large-Scale Phylogenomic Analyses Indicate a Deep Origin of Primary Plastids within Cyanobacteria

open access: yes, 2011
International audienceThe emergence of photosynthetic eukaryotes has played a crucial role in evolution and has strongly modified earth's ecology. Several phylogenetic analyses have established that primary plastids arose from a cyanobacterium through ...

Fletcheria gen. nov. (Ralfsiales, Phaeophyceae): A new crustose brown algal genus clarifying evolutionary relationships of Ralfsia pacifica

open access: yesJournal of Phycology, EarlyView.
Abstract The genus Ralfsia was historically broadly circumscribed but has recently undergone significant taxonomic revision. Based on molecular data, a restricted Ralfsia sensu stricto was delineated that had many species reassigned to new genera and families.

Genetic, phenotypic, and ecological differentiation indicate a new cryptic and threatened species in the orchid genus Epidendrum from Alcatrazes Island, southeastern Brazil

open access: yesJournal of Systematics and Evolution, EarlyView.
Epidendrum insularis occurs on the remote Alcatrazes Island in the southeastern Brazilian coast. The description of this new cryptic species was only possible by the joint use of molecular markers, reproductive experiments, flower morphometry, functional traits, and community analysis.

Molecular phylogenetic analysis sheds light on the diversity and evolutionary history of the Neotropical and African Triplophyllum (Tectariaceae)

open access: yesJournal of Systematics and Evolution, EarlyView.
We used a molecular approach to resolve the evolutionary lineages of Neotropical Triplophyllum, uncovering that current species circumscriptions are hindered by high morphological homoplasy in indument characters. Our results support the recognition of three new species and provide a necessary neotypification for T.

Transmission electron micrographs of E. chlorotica illustrating the acquisition of both lipids and plastids upon feeding.

open access: yes, 2014
(A,B) Aposymbiotic E. chlorotica at 1 dpm with neither plastids or lipids present in the digestive tissue. (C,D) Fed E. chlorotica at 1 dpm with large lipid accumulation and visible intracellular plastids.

Bacterial composition of Polygenis (Polygenis) bohlsi bohlsi (Wagner, 1901) (Siphonaptera: Rhopalopsyllidae) associated with Thrichomys fosteri (Rodentia: Echimyidae) in the Brazilian Pantanal wetland

open access: yesMedical and Veterinary Entomology, EarlyView.
This study characterizes the bacteriome of Polygenis (Polygenis) bohlsi bohlsi fleas collected from free‐living Thrichomys fosteri in the Pantanal region of Brazil. The bacterial microbiota associated with male fleas exhibited greater phylogenetic diversity, and the overall community structure differed between the flea sexes.

Jasmonate biosynthesis regulates key events in barley vegetative and reproductive development

open access: yesNew Phytologist, EarlyView.
Generation and general phenotypes of hvaoc mutants. Summary Cereal grain is a global food staple. Filial tissues in grain, such as the embryo and endosperm, grow embedded in the maternal ovule and surrounding ovary wall. Maternal tissues provide nutrition and protection but are progressively reduced and degraded as filial tissues expand, driving grain ...
