Integration of the D‐Genome Reshapes Gene Transcription, Chromatin Architecture, and Metabolome of Allohexaploid Wheat, Leading to Enhanced Environmental Adaptability

Advanced Science, EarlyView.
Integration of the D‐genome reshapes gene transcription, chromatin architecture, and the metabolome of hexaploid wheat, leading to enhanced adaptability to salt, UV‐B, and alkali stress. ABSTRACT The hybridization‐led integration of the D‐genome into domesticated tetraploid wheat gave rise to allohexaploid wheat, the most cultivated wheat globally ...

Botanical composition of Caatinga rangeland and diets selected by grazing sheep

Tropical Grasslands-Forrajes Tropicales, 2016
Sheep dietary selection from species-diverse Caatinga rangeland of semi-arid northeastern Brazil has not been documented. This study examined the botanical composition of the available forage and diets of Dorper x Saint Ines ewes on thinned Caatinga over-

MN•CS•IO System: Cross‐Species Study for HBB Function in High‐Altitude Hypoxia Adaptation

Advanced Science, EarlyView.
We developed an integrative mesh‐nanorod sorting, chitosan nanoparticle delivery, and intraosseous injection (MN•CS•IO) system to investigate HBB in high‐altitude hypoxia adaptation. Transplanting Tibetan animals' HBB‐modified Lin‐ cells into mice achieved 95.59% transfection efficiency and 8.15% HBB expression. High‐altitude HBB recipients upregulated

chlorophyll autofluorescence in globular and heart-shaped embryos of some dicotyledons

Acta Societatis Botanicorum Poloniae, 2014
The regions in early embryos of several species display chlorophyll autofluorescence in a certain order. First, autofluorescence in Pisum sativum appears in the basal part of globular embryos; in Lathyrus vernus in the basal part of early heart embryos ...

Linking community structure and climate vulnerability in desert plant assemblages of southern California

American Journal of Botany, EarlyView.
Abstract Premise Desert plant assemblages in southern California provide an opportunity to link patterns of community structure with climate‐driven vulnerability in a rapidly changing environment. California sustains an exceptionally diverse flora of approximately 4300 plant species, with 31% identified as endemic.

Holocene vegetation change and fire–plant diversity shifts in Mediterranean France

Journal of Quaternary Science, EarlyView.
ABSTRACT Changes in fire activity are recognized as a major threat to biodiversity and vegetation communities across the Mediterranean Basin. However, long‐term fire–vegetation interactions remain poorly investigated. Here, we combine a high‐resolution charcoal record with pollen data from the “Étang des Aulnes” lake (southern France) to reconstruct ...

The Simplest Leaf Organization Found in Surveys of Several Hundred Species of Dicotyledons [PDF]

, 1951
The number of cell-layers in leaves of dicotyledons varies considerably but within fairly definite limits. Extreme thickness of epidermis or mesophyll presently retards photosynthetic activity and is usually restricted to succulents and desert types.

Dental enamel hypoplasia and intra‐tooth isotope records as indicators of physiological stress and environmental variability in Early Pleistocene hippopotamids from Melka Kunture (Upper Awash, Ethiopia)

Journal of Quaternary Science, EarlyView.
ABSTRACT Enamel hypoplasia results from temporary disruptions of enamel deposition during tooth development. It is widely used as an indicator of physiological stress in archeological and paleontological contexts; yet, its relationship with environmental conditions during tooth formation remains poorly constrained.

Cross‐species transcriptomics uncovers shared responses to water deficiency in plants [PDF]

Plant Genome
Abstract Deepening our knowledge of conserved molecular mechanisms governing stress responses in plants is fundamental for identifying new core genes and processes involved in tolerance to adverse environmental conditions. For this purpose, we developed a bioinformatic pipeline to retrieve and integrate stress‐related RNA‐seq transcriptomic data from ...
