Two Populus deltoides W.Bartram ex Marshall clones cope differentially with sodium salinity stress

iForest - Biogeosciences and Forestry
Salt stress poses a challenge to tree species in regions where salinity occurs intermittently. Poplars (Populus spp.) are key species for forestry, yet their responses to salt stress remain underexplored, particularly within the intra-specific ...

Single‐Cell Transcriptomic Analysis Reveals Epithelial‐Mesenchymal Transition and Key Gene AGRN as a Universal Programme in Gastrointestinal Tumours by an Artificial Intelligence‐Derived Prognostic Index

Med Research, EarlyView.
Intra‐tumour heterogeneity is present in gastrointestinal tumours at the single‐cell level. Cell cycling, EMT, MYC and TNF‐α are the four main consensus meta‐programs in gastrointestinal tumours. Then, a prognostic model based on intratumoral heterogeneity was constructed using an artificial intelligence‐derived prognostic index.

Resource limitation and competition shape reproductive allocation and synchrony

Oikos, EarlyView.
The dynamics of reproductive allocation (RA) in herbaceous plant communities, particularly in response to varying environmental conditions such as drought stress and competitive interactions, remain underexplored. This study aims to fill this gap by hypothesising that both belowground resource limitation and the presence of dominant species ...

Cloning crops in a CELSS via tissue culture: Prospects and problems [PDF]

Micropropagation is currently used to clone fruits, nuts, and vegetables and involves controlling the outgrowth in vitro of basal, axillary, or adventitious buds. Following clonal multiplication, shoots are divided and rooted.

Whole‐seedling trait adjustments of mountain birch under contrasting environmental conditions

Oikos, EarlyView.
Warming temperatures can promote arctic tree seedling establishment and growth, but these effects depend on the environmental context and the seedlings' capacity to acquire limiting resources. Here, we tested how temperature, soil properties, and the presence of a neighbouring shrub influence seedling growth rates.

Priority Forestry Research Areas with Potential for International Centralization [PDF]

, 1989
Paper by Hans Gregersen and John Spears prepared as part of TAC's consideration of the approach to including forestry in the CGIAR mandate. It was marked Interim Draft, but was approved for circulation without change by the steering group of the ad hoc ...

Time tells: plasticity and developmental asynchrony underlie trait variation in a dune‐building grass

Oikos, EarlyView.
Habitat‐modifying plants engineer landscapes through plant‐environment feedbacks. The strength of these feedbacks is determined by above‐ and below‐ground traits shaping landscape morphology. Besides interspecific differences, recent findings highlight that intraspecific trait variation, such as shoot density, can also influence landscape morphology ...

Social and cultural considerations for the restoration of ‘lost’ tree species: The fall and rise of elm

People and Nature, EarlyView.
Abstract Attempts to address biodiversity loss have led to ecosystem and species restoration efforts. Tree species restoration is particularly relevant because of increasing threats from pests and pathogens. However, there are different notions of ‘loss’, as well as sociocultural considerations, including social acceptability, which are often neglected

Establishment of a clonal bank of Caesalpinia spinosa (Mol.) O. Kuntz by selection of plus trees and grafting

Biotecnología Vegetal, 2017
In Ecuador, plant propagation techniques are not available commercially to establish clonal banks of Caesalpinia spinosa (Mol.) O. Kuntz (guarango) plus trees, which limits the development of in vitro propagation protocols of this specie.

Hemophilia A: An Ideal Disease for Prenatal Therapy

Prenatal Diagnosis, EarlyView.
ABSTRACT Hemophilia A (HA) is the most common inherited coagulation defect. Current state‐of‐the‐art treatment consists of frequent administration of prophylactic infusions of coagulation factor VIII (FVIII) protein or bispecific antibodies that replace the cofactor function of FVIIIa to maintain hemostasis. However, these treatments are far from ideal,
