A revised view on the evolution of glutamine synthetase isoenzymes in plants. [PDF]

Plant J, 2022
SUMMARY Glutamine synthetase (GS) is a key enzyme responsible for the incorporation of inorganic nitrogen in the form of ammonium into the amino acid glutamine. In plants, two groups of functional GS enzymes are found: eubacterial GSIIb (GLN2) and eukaryotic GSIIe (GLN1/GS).

Step-by-step protocol for the isolation and transient transformation of hornwort protoplasts. [PDF]

Appl Plant Sci, 2022
Abstract Premise A detailed protocol for the protoplast transformation of hornwort tissue is not yet available, limiting molecular biological investigations of these plants and comparative analyses with other bryophytes, which display a gametophyte‐dominant life cycle and are critical to understanding the evolution of key land plant traits. Methods and

Comprehensive phylogenomic time tree of bryophytes reveals deep relationships and uncovers gene incongruences in the last 500 million years of diversification

American Journal of Botany, Volume 110, Issue 11, November 2023., 2023
Abstract Premise Bryophytes form a major component of terrestrial plant biomass, structuring ecological communities in all biomes. Our understanding of the evolutionary history of hornworts, liverworts, and mosses has been significantly reshaped by inferences from molecular data, which have highlighted extensive homoplasy in various traits and repeated

Causal inference and large‐scale expert validation shed light on the drivers of SDM accuracy and variance

Diversity and Distributions, Volume 29, Issue 6, Page 774-784, June 2023., 2023
Abstract Aim To develop a causal understanding of the drivers of Species distribution model (SDM) performance. Location United Kingdom (UK). Methods We measured the accuracy and variance of SDMs fitted for 518 species of invertebrate and plant in the UK.

Early land plants: Plentiful but neglected nutritional resources for herbivores?

Ecology and Evolution, Volume 12, Issue 12, December 2022., 2022
In this paper, we explore the unknown reason(s) why herbivores rarely seem to attack early land plants like mosses and ferns. Our study, in which we looked at the performance of an arthropod and a gastropod on 15 species of such plants, yields surprising results that disqualify some of the common notions about early land plants.

Elevational patterns in tropical bryophyte diversity differ among substrates: A case study on Baru volcano, Panama

Journal of Vegetation Science, Volume 33, Issue 3, May/June 2022., 2022
Bryophytes are an essential component in tropical mountains. Understanding their distribution will help interpret linkages and possible changes in diversity in an environment threatened by human action and global warming. We present here the study case of the Baru volcano, a mountain surrounded by agricultural sites and cities.

Desiccation tolerance in bryophytes relates to elasticity but is independent of cell wall thickness and photosynthesis

Physiologia Plantarum, Volume 174, Issue 2, March/April 2022., 2022
Abstract Mosses have been found outliers of the trade‐off between photosynthesis and bulk elastic modulus described for vascular plants. Hence, potential trade‐offs among physical features of cell walls and desiccation tolerance, water relations, and photosynthesis were assessed in bryophytes and other poikilohydric species.

Evolution of plant ribosome-inactivating proteins [PDF]

, 2010
This contribution presents an updated analysis of the evolution of ribosome-inactivating proteins (RIPs) in plants. All evidence suggests that an ancestor of modern seed plants developed the RIP domain at least 300 million years ago.

Nuevos registros de distribución para la flora de antocerotes (Anthocerotophyta) y hepáticas (Marchantiophyta) de la Patagonia, Argentina

Lilloa, 2023
En la Argentina la flora de antocerotes y hepáticas fue intensamente estudiada; sin embargo, la información de algunos grupos taxonómicos y su distribución geográfica dentro del país aún necesita ser actualizada o ampliada.
