Накратко на български

Веществата, които корените на растенията отделят в почвата, се проследяват чрез специални микрофлуидни листове, например при доматите. Това помага за разбирането на взаимодействието с бактериите, което може да подобри устойчивостта на културите и екологичното земеделие.

Patterned microfluidic sheets for studies of root exudation profiles

Root exudates have a key role in the life of a plant. They control critical processes, like water retention capability of soil, root penetrability into soil, they can mobilize nutrients and they can influence the microbial environment around the root. Some of the microbial interactions can positively increase the plant's stress resiliency, can improve the nutrient uptake and immune responses of the plant. Using these beneficial interactions could revolutionise our agriculture, leading to a more sustainable eco friendly crop production. Unfortunately, the available technologies cannot address this problem with sufficient spatio-temporal resolution and in a cost effective way. The RhizoSheet project addressed the above mentioned challenges. Using cutting edge paper-polymer technologies a microfluidic device was developed to monitor root exudates over time along the root. The project had four main research objectives: O1 Identify materials and fabrication techniques for assembling RhizoSheet microfluidic system and sensors. O2 Achieve, in situ, robust extraction and mapping of exudates along a growing root, over time. O3 Generate a reference high resolution library of root exudates of tomato plant. O4 Localise temporally and spatially the place of exudation and interaction with bacteria.

Цел на проекта

Modern plant varieties have been bred to grow and increase production under non limiting soil conditions and have consequently lost their ability to capture resources efficiently. Designing an efficient fertiliser requires optimising bioavailability and mobility of nutrients. Unfortunately, bio-availability and mobility are often antagonistic. Traditional fertilisers, which package soluble mineral elements into granules, are easily acquired by plant roots but have been linked to excessive loss to the environment and pollution. Slow release fertilisation has been proposed to slow down the diffusion of nutrients to the soil, including the use of nanotechnology, but slowing down the diffusion of nutrients excessively affects root uptake. Biological fertilisation is inspired from known mechanisms observed in soil, but maintaining efficient colonisation of the root by beneficial microbes is challenging. New approaches must be developed to better control the associations taking place between plants and beneficial microbes, since fundamental knowledge to achieve this target is nowadays lacking. Roots exude a huge diversity of biomolecules, and their role in maintaining adequate beneficial microbes are mostly unknown and rarely studied. The aim of the RhizoSheet project is to apply cutting-edge microfluidic techniques based on hybrid paper-polymer technology for device fabrication. Optical sensors and novel functional materials will be applied as biochemical sensors to gain knowledge on the location of compounds secreted by roots and on the response of roots over time, when interacting with soil microbes.The acquired knowledge will be highly beneficial for the scientific and agricultural community and finds the interest of the EU in soil and food safety, the RhizoSheet project meets the interest of the Horizon Europe - the next research and innovation framework programme in particular the natural resources in Pillar 1.
