Tripartite Symbiosis Between Legumes, Arbuscular Mycorrhizal Fungi and Nitrogen Fixing Rhizobia: Interactions and Regulation

Plant, Cell &Environment, EarlyView.
ABSTRACT Legume plants can interact with nitrogen‐fixing rhizobia bacteria and arbuscular mycorrhizal fungi (AMF) simultaneously, forming a tripartite symbiotic association. Co‐inoculation studies performed on a variety of legumes have shown that rhizobia and AMF influence each other when they co‐occur in tripartite association and affect host plant ...

Coping with Water Scarcity: What Role for Biotechnologies? [PDF]

, 2008
At a conference of the FAO Biotechnology Forum in 2007, 78 participants from 24 countries offered their views on agricultural biotechnologies and water scarcity, addressing the pros and cons of various methods and their potential application.

Rhizobia–Bean Symbiosis Increases Root Herbivore Attraction and Growth via Volatile Signals and Enhanced Nutrition

Plant, Cell &Environment, EarlyView.
ABSTRACT The symbiosis between nitrogen‐fixing rhizobia and plants is considered mutually beneficial, yet its indirect effects on other organisms remain understudied. We examined how rhizobia symbiosis in Phaseolus vulgaris influences the behaviour and performance of Diabrotica balteata larvae. Specifically, we tested larval preference for nodulated (R+

Non‐Additive Interactions Between Multiple Mutualists and Host Plant Genotype Simultaneously Promote Increased Plant Growth and Pathogen Defence

Plant, Cell &Environment, EarlyView.
ABSTRACT Understanding the impact of microbial interactions on plants is critical for maintaining healthy native ecosystems and sustainable agricultural practices. Despite the reality that genetically distinct plants host multiple microbes of large effect in the field, it remains unclear the extent to which host genotypes modulate non‐additive ...

Examining the Effects of Urbanization on Soil Characteristics in Portland, Oregon\u27s Forest Park [PDF]

, 2016
Studies by Dr. Nancy Broshot in Forest Park, an urban forest in Portland, Oregon, have shown high tree mortality and low concomitant recruitment. Lichen surveys conducted in 2013 revealed a shift in the lichen community to one typified by nitrogen ...

A Volatile Cue From a Specialist Herbivore Primes Gene Expression Against Biotic Stress in Tall Goldenrod (Solidago altissima L.)

Plant, Cell &Environment, EarlyView.
ABSTRACT Insect‐derived molecular cues can prime plant defences against herbivore attack. The genes that are sensitive to priming, and how their expression changes on the scale of days, have not been fully resolved. Moreover, priming may affect interactions with insects that are not the source of the priming cue.

Nitrogen Isotope Fractionation During Nitrate and Ammonium Uptake in Maize: Hydroponic Evidence and Implications for Ecological Investigations

Plant, Cell &Environment, EarlyView.
ABSTRACT Understanding nitrogen (N) isotopic fractionation during plant uptake is critical for interpreting δ15N variations in terrestrial ecosystems. We investigated isotopic discrimination during ammonium (NH4+) or nitrate (NO3−) uptake in maize (Zea mays) grown hydroponically under controlled conditions with 0.2 and 2 mM to represent high and low ...

Les mycorhizes à vésicules et arbuscules chez la vigne

OENO One, 1985
La présence de mycorhizes à vésicules et arbuscules (VA) est très répandue dans les vignobles. Le symbiote fongique peut influencer positivement l'absorption de phosphate et par conséquence la croissance de la plante.

Native and invasive inoculation sources modify fungal community assembly and biomass production of a chaparral shrub [PDF]

, 2020
Feedbacks between plants and surrounding soil microbes can contribute to the establishment and persistence of invasive annual grasses as well as limit the success of restoration efforts.

Arbuscular Mycorrhizal Fungi Mitigate Drought‐Enhanced Herbivore Performance in Maize

Plant, Cell &Environment, EarlyView.
ABSTRACT Drought events are becoming increasingly frequent and intense, posing major challenges to crop productivity. Beyond direct water stress, drought can indirectly affect plants by enhancing herbivore performance. While arbuscular mycorrhizal fungi (AMF) have been proposed to alleviate drought stress and to enhance plant resistance to herbivory ...
