Decontamination of water objects from 137Cs by means of bioplateau

open access: yesЯдерна фізика та енергетика, 2019
Mobile bioplateau design has been developed for water bodies treatment from ions 137Cs. Comparative study of the cleaning efficiency of different species of plants-hyperaccumulators of the aqueous medium from radiocaesium ions has been carried out.

The end-Cretaceous plant extinction: Heterogeneity, ecosystem transformation, and insights for the future

open access: yesCambridge Prisms: Extinction, 2023
The Cretaceous–Paleogene (K–Pg) mass extinction was geologically instantaneous, causing the most drastic extinction rates in Earth’s History. The rapid species losses and environmental destruction from the Chicxulub impact at 66.02 Ma made the K–Pg the ...

Former land use affects the nitrogen and phosphorus concentrations and biomass of forest herbs [PDF]

open access: yes, 2011
The colonization rates of understorey plants into forests growing on former agricultural land differ remarkably among species. Different dispersal and recruitment largely account for the contrasting colonization rates, but different effects of the soil ...

Fragments of the earliest land plants [PDF]

open access: yes, 2003
The earliest fossil evidence for land plants comes from microscopic dispersed spores. These microfossils are abundant and widely distributed in sediments, and the earliest generally accepted reports are from rocks of mid-Ordovician age (Llanvirn, 475 ...

Diversity of phyllotaxis in land plants in reference to the shoot apical meristem structure

open access: yesActa Societatis Botanicorum Poloniae, 2016
Regularity and periodicity in the arrangements of organs in all groups of land plants raise questions about the mechanisms underlying phyllotactic pattern formation.

Different fates of the chloroplast tufA gene following its transfer to the nucleus in green algae [PDF]

open access: yes, 1990
Previous work suggested that the tufA gene, encoding protein synthesis elongation factor Tu, was transferred from the chloroplast to the nucleus within the green algal lineage giving rise to land plants.

Molecular Evolution and Expression Divergence of Aconitase (ACO) Gene Family in Land Plants

open access: yesFrontiers in Plant Science, 2016
Aconitase (ACO) is a key enzyme that catalyzes the isomerization of citrate to isocitrate in the tricarboxylic acid (TCA) and glyoxylate cycles. The function of ACOs has been well studied in model plants, such as Arabidopsis.

ABA activated SnRK2 kinases: an emerging role in plant growth and physiology

open access: yesPlant Signaling & Behavior, 2022
Members of the SNF1-related protein kinase 2 (SnRK2) family are plant-specific serine or threonine kinases that play a pivotal role in the response of plants to abiotic stresses.

Endophytic PGPR from Tomato Roots: Isolation, In Vitro Characterization and In Vivo Evaluation of Treated Tomatoes (Solanum lycopersicum L.)

open access: yesMicroorganisms, 2022
Plant-growth-promoting rhizobacteria (PGPR) are soil bacteria colonizing the rhizosphere and the rhizoplane which have an effect on plant growth through multiple chemical compounds. Rhizobacteria with beneficial effects for plants could therefore be used

Abiotic Stresses: General Defenses of Land Plants and Chances for Engineering Multistress Tolerance

open access: yesFrontiers in Plant Science, 2018
Abiotic stresses, such as low or high temperature, deficient or excessive water, high salinity, heavy metals, and ultraviolet radiation, are hostile to plant growth and development, leading to great crop yield penalty worldwide.
