The Ectopic Expression of Btr2 in Aegilops tauschii Switches the Disarticulation Layer From Above to Below the Rachis Node

open access: yesFrontiers in Plant Science, 2020
Seed dispersal among wild species belonging to the tribe Triticeae is typically achieved by the formation of a brittle rachis. The trait relies on the development of a disarticulation layer, most frequently above the rachis node (resulting in wedge type ...

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.

The Brittle Rachis Trait in Species Belonging to the Triticeae and Its Controlling Genes Btr1 and Btr2

open access: yesFrontiers in Plant Science, 2020
In many non-cultivated angiosperm species, seed dispersal is facilitated by the shattering of the seed head at maturity; in the Triticeae tribe, to which several of the world's most important cereals belong, shattering takes the form of a disarticulation

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.

New components in genetic regulation of age‐dependent compound leaf architecture in pea

open access: yesNew Phytologist, EarlyView.
Compound leaf development in pea (Pisum sativum). Summary Pea (Pisum sativum L.) is a classic model for compound leaf development. Pea leaves typically consist of a proximal series of paired lateral leaflets substituted distally by filiform tendrils, and the number of lateral organ pairs increases with ontogeny.

Durum Wheat cv. Svevo Reference Genome Rel.2.0: A Comprehensive Tool for Wheat Genomics

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Advancements in plant genome sequencing and assembly have enabled the production of increasingly accurate and contiguous genome sequences. Here, we present the chromosome‐level assembly of the durum wheat (Triticum turgidum L. ssp. durum, cv. Svevo) reference genome produced using accurate long‐reads, optical mapping and Hi‐C. The new assembly

Post‐Translational Control of TaFT1 by WAPO1 Ubiquitination Shapes Spike Architecture and Yield in Wheat

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT The florigen protein TaFT1 coordinately regulates heading time and spikelet number per spike (SNS), serving as a key yield determinant in wheat. However, how its stability is post‐translationally controlled in the shoot apical meristem remains unclear.

Piper longiapiculatum (Piperaceae), a New Species From the Brazilian Amazon Piper longiapiculatum (Piperaceae), uma Nova Espécie da Amazônia Brasileira

open access: yesFeddes Repertorium, Volume 137, Issue 3, September 2026.
ABSTRACT In order to address the many lacunae in Amazonian Piper taxonomy and geography, we performed a field expedition in the Serra do Divisor National Park (Acre state, Brazil), resulting in the discovery of a new species, Piper longiapiculatum, herein described and compared to morphologically similar taxa.

Aciphylla latipinna, a New Species of Large Taramea, Speargrass (Aciphylleae, Apiaceae) From the Southern South Island of New Zealand

open access: yesNew Zealand Journal of Botany, Volume 64, Issue 3, September 2026.
Aciphylla latipinna Perrie, Glenny, & L.D.Sheph. is newly described after testing the morphological and genetic distinctness of a long‐recognised unresolved taxonomic entity whose informal names include Aciphylla aff. horrida (a) (CHR 511521; Lomond). Analyses of genetic data from ddRADseq DNA sequencing found A.
