Long‐term population dynamics of western tent caterpillars: History, trends and causes of cycles

open access: yesJournal of Animal Ecology, EarlyView.
The length and in‐depth nature of this population study make it unique. It represents perhaps the most extensive monitoring of viral infection in a wild insect population. We have used laboratory and field experiments to test many hypotheses about mechanisms that potentially impact the dynamics of this cyclic species.

Evaluation of Finnish apple cultivars (Malus domestica Borkh.)

open access: yesAgricultural and Food Science, 2020
The purpose of this research was to study apple cultivars obtained from Luke (previously MTT Piikkiö, Finland) in order to have good candidates for breeding within the central zone of Russia. The studies were carried out in accordance with the methods of cultivar study and artificial freezing by modeling damaging factors using a freezing chamber.

Calcium oxalate crystals of plant leaves pass through chewing invertebrate larvae virtually unchanged

open access: yesPlant Species Biology, EarlyView.
Can calcium oxalate crystals protect plants against herbivorous insects? These Hazel leaves are consumed by caterpillars despite their high content of mineral druses (right image, arrows. Scale bar = 100 μm). This study illustrates what happens to crystals and caterpillars after the meal.

Frequency of a natural truncated allele of MdMLO19 in the germplasm of Malus domestica [PDF]

open access: yesMolecular Breeding, 2017
Podosphaera leucotricha is the causal agent of powdery mildew (PM) in apple. To reduce the amount of fungicides required to control this pathogen, the development of resistant apple cultivars should become a priority. Resistance to PM was achieved in various crops by knocking out specific members of the MLO gene family that are responsible for PM ...

Cossid moths (Lepidoptera: Cossidae) as pests of woody plants – A review

open access: yesAgricultural and Forest Entomology, EarlyView.
Abstract The Cossidae is a worldwide family of macro‐moths popularly known as carpenter moths due to the larval habit of boring in the wood of living plants. This review compiles current knowledge on the characteristics, diversity and bionomy of cossid moths as well as the damage they cause on woody plants.

Comparative analysis of plant immune receptor architectures uncovers host proteins likely targeted by pathogens. [PDF]

open access: yes, 2016
BACKGROUND: Plants deploy immune receptors to detect pathogen-derived molecules and initiate defense responses. Intracellular plant immune receptors called nucleotide-binding leucine-rich repeat (NLR) proteins contain a central nucleotide-binding (NB ...
