DOI: 10.1002/ps.6791
Abstract: BACKGROUND Here we investigated changes in primary metabolism and cell death around oviposition sites in two hybrid clones of Eucalyptus with different degree of resistance to Leptocybe invasa Fisher & La Salle (Hymenoptera: Eulophidae), as… read more here.

DOI: 10.1002/ps.6941
Abstract: BACKGROUND Helicoverpa armigera is a major insect pest of several crop plants, including pigeonpea. Resistant gene sources are not available in the cultivated gene pool, however, resistance has been observed in its crop wild relative,… read more here.

DOI: 10.1002/ps.7432
Abstract: BACKGROUND The phoma stem canker pathogen Leptosphaeria maculans is one of the most widespread and devastating pathogens of oilseed rape (Brassica napus) in the world. Pathogen colonisation is stopped by an interaction of a pathogen… read more here.

DOI: 10.1007/s00049-020-00315-3
Abstract: Thapsigargin and related compounds are produced by Thapsia garganica L. (Apiaceae) and are thought to be a defence compound against herbivory. Thapsigargin inhibits the sarco-endoplasmic reticulum Ca 2+ -ATPase (SERCA) in both vertebrates and invertebrates.… read more here.

DOI: 10.1007/s00265-019-2672-1
Abstract: Individuals of many animal species show consistent differences in ecologically relevant behaviours, and these individual-specific behaviours can correlate with each other. In passerines, aggression during nest-site defence is one of those behaviours that have been… read more here.

Mechanistic Elucidation of Salicylic Acid and Sulphur-Induced Defence Systems, Nitrogen Metabolism, Photosynthetic, and Growth Potential of Mungbean (Vigna radiata) Under Salt Stress
Sign Up to like & getrecommendations! Published in 2020 at "Journal of Plant Growth Regulation"
DOI: 10.1007/s00344-020-10159-4
Abstract: The potential of plant nutrients (such as sulphur, S) and phytohormones (such as salicylic acid, SA) has been explored in isolated studies by researchers in controlling the impact of abiotic stresses such as salinity in… read more here.

DOI: 10.1007/s00425-020-03497-w
Abstract: MAIN CONCLUSION Cotton genotypes displayed similar volatile organic compound (VOC) profiles, but major differences in terpenoid aldehyde (TA) content. The differences in VOC production were minor among genotypes, but these differences are crucial for boll… read more here.

DOI: 10.1007/s00442-018-4162-y
Abstract: Predicting variation in plant functional traits related to anti-herbivore defences remains a major challenge in ecological research, considering that multiple traits have evolved in response to both abiotic and biotic conditions. Therefore, understanding variation in… read more here.

DOI: 10.1007/s10452-017-9625-4
Abstract: The success of an invasive plant species could be explained by trade-off between growth and defence. The aim of this paper was to explore the responses of two non-native aquatic macrophytes Elodea canadensis and Elodea… read more here.
