Historic disturbance events overruled climatic factors as drivers of ruderal species distributions in the Scandinavian mountains

open access: yesNordic Journal of Botany, EarlyView.
The contemporary interaction of climate and disturbance drives vegetation composition and species distribution shifts, making their respective roles difficult to disentangle. This study describes the long‐term ruderal plant species distributions along the ‘Rallarvägen' in Abisko, subarctic Sweden.

Photorespiration: metabolic pathways and their role in stress protection [PDF]

open access: yes, 2000
Photorespiration results from the oxygenase reaction catalysed by ribulose-1,5-bisphosphate carboxylase/ oxygenase. In this reaction glycollate-2-phosphate is produced and subsequently metabolized in the photorespiratory pathway to form the Calvin ...

Cold hardiness mechanisms and modeling: existing approaches and future avenues

open access: yesNew Phytologist, EarlyView.
Summary Cold hardiness models are useful tools to predict cold damage in plants, such as those produced by unseasonal temperature cycles or by increased cold exposure. Although development of these models started about five decades ago, their applications remain limited.

Characterisation of components and mechanisms involved in redox-regulation of protein import into chloroplasts [PDF]

open access: yes, 2009
The vast majority of chloroplast proteins is encoded in the nucleus and thus has to be posttranslationally imported into the organelle, a process that is facilitated by two multimeric protein machineries, the Toc and Tic complexes (translocon at the ...

Loss‐of‐Function Mutation in CER2‐LIKE1 Reduced Accumulation of Cuticular Wax and Susceptibility to Thrips in Welsh Onion

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Cuticular waxes can form a hydrophobic barrier on aerial plant surfaces, which is essential for mediating plant‐environment interactions by providing protection against both biotic and abiotic stresses. In this study, a cuticular wax mutant (gl) was identified and characterised in Welsh onion (Allium fistulosum L.), exhibiting a functional ...

Isolation and characterization of Pisum sativum apyrases, PsNTP9 and PsNTP9-DM, cloned and expressed in Escherichia coli [PDF]

open access: yes, 2019
Adenosine triphosphate (ATP) is widely known as a fuel source for many biochemical processes, and to a lesser degree also as a signaling molecule in plants and animals.

Micromorphology of the model species pea aphid Acyrthosiphon pisum (Hemiptera, Aphididae) with special emphasis on the sensilla structure

open access: yesThe European Zoological Journal, 2020
The pea aphid complex [Acyrthosiphon pisum (Harris 1776)] (Hemiptera, Aphididae), listed among the 14 aphid species of the greatest economic importance, is a globally distributed key pest of pulse crops.
