Changes produced in extra-virgin olive oils from cv. Coratina during a prolonged storage treatment

open access: yesCzech Journal of Food Sciences, 2014
Extra-virgin oil is obtained from olive fruits only by mechanical means. The quality of extra-virgin olive oils is affected mainly by hydrolytic and oxidative reactions. For this reason, the commercial shelf-life is usually no longer than 18 months.

Pathogenesis-Related Proteins (PRs) with Enzyme Activity Activating Plant Defense Responses

open access: yesPlants, 2023
Throughout evolution, plants have developed a highly complex defense system against different threats, including phytopathogens. Plant defense depends on constitutive and induced factors combined as defense mechanisms.

Impacts of nitrogen on plant disease severity and plant defense mechanism

open access: yesFundamental and Applied Agriculture, 2020
Nitrogen(N) is considered the most important factor to help the growth and development of plants. This is the building block for plant protoplasm and the chlorophyll molecule component for the photosynthesis process as well.

An effector of the Irish potato famine pathogen antagonizes a host autophagy cargo receptor [PDF]

open access: yes, 2016
Plants use autophagy to safeguard against infectious diseases. However, how plant pathogens interfere with autophagy-related processes is unknown. Here, we show that PexRD54, an effector from the Irish potato famine pathogen Phytophthora infestans, binds

Transmethylation and the general defense reaction of plants

open access: yesInternational Journal of Horticultural Science, 2007
Plant breeding for resistance, namely building specific resistance genes into cultivated plants to ensure resistance against certain pathogen species, is a several-decade-long practice.

The pathogen Moniliophthora perniciosa promotes differential proteomic modulation of cacao genotypes with contrasting resistance to witches´ broom disease [PDF]

open access: yes, 2020
Background: Witches' broom disease (WBD) of cacao (Theobroma cacao L.), caused by Moniliophthora perniciosa, is the most important limiting factor for the cacao production in Brazil.

Genome-wide dynamic network analysis reveals the potential genes for MeJA-induced growth-to-defense transition

open access: yesBMC Plant Biology, 2021
Background Methyl jasmonate (MeJA), which has been identified as a lipid-derived stress hormone, mediates plant resistance to biotic/abiotic stress.

Tetranychus evansi spider mite populations suppress tomato defenses to varying degrees

open access: yesEcology and Evolution, 2020
Plant defense suppression is an offensive strategy of herbivores, in which they manipulate plant physiological processes to increase their performance. Paradoxically, defense suppression does not always benefit the defense‐suppressing herbivores, because
