The Role of Silicon in Antiherbivore Phytohormonal Signalling

Frontiers in Plant Science, 2019
The role of plant silicon (Si) in the alleviation of abiotic and biotic stress is now widely recognised and researched. Amongst the biotic stresses, Si is known to increase resistance to herbivores through biomechanical and chemical mechanisms, although ...

Defensive role of allelopathic secondary compounds in plants: a review of data on two independent general hypotheses [PDF]

, 2018
This review examines and whenever appropriate, reanalyses published literature related to two general and independent hypotheses having the underlying assumption that phytoactive secondary compounds produced by plants evolved primarily as plant defences ...

Development of an Artificial Liquid Diet for Allelochemical Delivery in Lycorma delicatula

Journal of Applied Entomology, EarlyView.
ABSTRACT Spotted lanternfly, Lycorma delicatula White (Hemiptera: Fulgoridae), is an invasive phloem‐feeding planthopper native to Asia, which poses a growing threat to US agriculture due to its broad host range and rapid spread since its 2014 detection. To better understand how L.

Resistance of tomato genotypes with high level of acylsugars to Tetranychus evansi Baker & Pritchard Resistência de genótipos de tomateiro com alto teor de acilaçúcares a Tetranychus evansi Baker & Pritchard

Scientia Agricola, 2008
The Lycopersicon pennellii accession LA716 has been used as a source of arthropod pest resistance in tomato breeding programs due the high contents of acylsugars presents in its leaflets.

Allelopathic Observations in Rice (Oryza sativa L.) to Ducksalad (Heteranthera limosa) [PDF]

, 1989
More than 50 weed species infest drill-seeded rice in the U.S. and one of the most prevalent aquatic weeks is ducksalad (Heteranthera limosa). During the summer of 1988, a field experiment was conducted to identify rice accessions from the USDA/ARS rice ...

Ecological and genomic variation in ectomycorrhizal fungal exploration types

New Phytologist, EarlyView.
Summary Ectomycorrhizal fungi (EMF) produce mycelia with variable extension and complexity, which can be classified according to soil ‘exploration types’ (ETs). ETs have received attention as one of the few mycorrhizal trait frameworks, but without an empirical classification of ET functional diversity and environmental preferences, understanding and ...

The Impact of Life History Traits and Defensive Abilities on the Invasiveness of Ulex europaeus L.

Diversity
Ulex europaeus L. has been introduced into many countries as an ornamental and hedgerow plant, and it often escapes its intended location, establishing dense, feral thickets. These thickets threaten the structure and function of native flora and fauna in

Deciphering Role of Endophytes in Plant Defences and Biotic Stress Resilience Across Families

Plant, Cell &Environment, EarlyView.
ABSTRACT Plant families generate distinct repertoires of specialised metabolites that govern their biotic interactions. Endophytes strengthen host plant defence mechanisms and tolerance to biotic challenges by upregulating metabolite biosynthesis, modifying precursor compounds into more potent forms, or by directly synthesising analogous defence ...
