Weeds in a changing climate: Competitors or service plants?
PLANTS, PEOPLE, PLANET, EarlyView.Reducing herbicide use and preparing agroecosystems for climate change are two top priorities on the global policy agenda. Here, we explore whether these two challenges can be tackled simultaneously. While weeds are generally considered a threat to crop production, we show that weeds can help overcome climate change challenges in agroecosystems ...

PLANTS, PEOPLE, PLANET, EarlyView.Traditional fermented foods worldwide depend on naturally occurring microbes, yet the environmental sources shaping these microbes and their effects on food quality remain poorly understood. We investigated bacteria living inside the roots of wild plants used to produce Munkoyo, a widely consumed nonalcoholic fermented cereal beverage in Zambia, to ...

Evaluation of electrolyzed water to control fungal trunk pathogens in grapevine nurseries
Pest Management Science, Volume 81, Issue 4, Page 1740-1751, April 2025.Electrolyzed water treatments could have promising applications in the grapevine nursery process to prevent or reduce infections caused by fungal trunk pathogens on grapevine propagation material. Abstract BACKGROUND Grapevine producers demand solutions to control fungal trunk pathogens (FTPs) in nurseries.

Plant and Soil, 1972
Comparisons have been made of the amount and composition of seed and seedling exudates in barley, wheat, cucumber, and bean. Except in the case of wheat a greater proportion of the total nitrogen content in the seed exudates was formed by protein and peptide nitrogen than by nitrogen of free amino acids.

Root exudation is an important ecological phenomenon which can manipulate plant and microbial succession. Under sterile conditions only 5–10% of the fixed carbon is released by roots compared to 12–% released from roots in nonsterile soil and the increase is attributed to rhizosphere microflora. There is more exudation by symbiotic plants.

The Botanical Review, 1969
Although the quantities of organic compounds exuding from roots is not large, seldom exceeding 0.4% of the carbon photosynthesized, they do exert a very strong influence on the soil microorganisms and may be significant in affecting plant nutrient availability.

Roots of many weed and crop species contribute biologically active chemicals into the environment known as root exudates. Root exudates are known to influence growth and establishment of crop and weed species, and these are released from living root systems.

Root Exudates Impact on Phenanthrene Availability
Water, Air, & Soil Pollution: Focus, 2006In order to improve and optimize phytoremediation of PAH we propose to focus on the rhizospheric processes controlling PAH degradation. In this paper the effect of root exudates on PAH availability is studied. Model organic compounds (malic acid, malonic acid and EDTA) representing root exudates have been tested for their effect on phenanthrene ...

Root exudate signals in plant–plant interactions
Plant, Cell & Environment, 2020AbstractPlant‐to‐plant signalling is a key mediator of interactions among plant species. Plants can perceive and respond to chemical cues emitted from their neighbours, altering survival and performance, impacting plant coexistence and community assembly. An increasing number of studies indicate root exudates as key players in plant‐to‐plant signalling.

Factors Affecting Root Exudation
1971Publisher Summary The absorption and desorption of substances that are extremely diverse in molecular size and in physicochemical and biological properties occur at the root surface. Substances (other than water) which are released from plant surfaces have been termed as “exudates” by many investigators, regardless of whether their appearance on the ...
