These wounds can be caused by several agents, such as bad weather, predators (herbivores, insects) or humans (pruning, grafting), among others, and are a breach of the outer protective layers (the skin) of plants, giving open access to many microbial pathogens that can cause severe diseases, resulting in dramatic crop losses for farmers.<\/p>\n<p>Now, the teams lead by\u00a0Dr. Anna Laromaine\u00a0at the Institute of Materials Science of Barcelona (ICMAB-CSIC) and by\u00a0Dr. N\u00faria S\u00e1nchez Coll\u00a0at the Centre for Research in Agricultural Genomics (CRAG) have developed a\u00a0material to avoid contamination and heal these plant wounds. This solution is based on the use of an environmentally friendly\u00a0nanocomposite patch made of bacterial cellulose and silver nanoparticles.<\/p>\n<p>Bacterial cellulose\u00a0is a very\u00a0efficient wound healing material,\u00a0currently being used in medicine thanks to its high biocompatibility. An advantage of this biopolymer is that its\u00a0molecular structure is similar\u00a0to plant cellulose, one of the plant\u2019s main structural components. Moreover, due to its high-water holding capacity, bacterial cellulose has a hydrogel-like consistency, which increases its adherence to the plant leaves. The wound healing properties of bacterial cellulose have already been patented.<\/p>\n<p>Currently, the efficacy and efficiency of the pesticides used to fight crop infections still face many challenges. Seeking to improve them, the ICMAB-CRAG team has anchored silver nanoparticles, which have antipathogenic properties, to the bacterial cellulose structure. The hybrid patch herein developed by Laromaine and S\u00e1nchez Coll, avoids runoff loss and rolling down of the nanoparticles, providing a slow and effective release of the pesticide effects from the bacterial cellulose. \u201cOur hybrid patches should be safer for the environment than most current pesticides, which are based on liquid dispersions of silver compounds or nanoparticles\u201d, explains Anna Laromaine, researcher from the ICMAB-CSIC. \u201cAlthough the price of those materials is still not comparable to the currently used bulk products, they could find a niche in high value applications\u201d, comments N\u00faria Sanchez Coll, researcher from CRAG.<\/p>\n<p>The research team demonstrated the positive antibacterial and antifungal properties of these hybrid patches in\u00a0<em>in vitro<\/em>\u00a0assays against\u00a0<em>Escherichia coli<\/em>\u00a0and two agro-economically relevant pathogens: the bacterium\u00a0<em>Pseudomonas syringae<\/em>\u00a0and the fungus\u00a0<em>Botrytis cinerea<\/em>. In addition,\u00a0<em>in vivo\u00a0<\/em>infection inhibition was proved in two different plants (<em>Nicotiana benthamiana<\/em>\u00a0and tomato plant leaves).<\/p>\n<p>This article is the first research outcome of the collaborative project between Dr. Anna Laromaine, from the Nanoparticles and Nanocomposites Group at the ICMAB-CSIC, and Dr. N\u00faria S\u00e1nchez Coll, from the Group of Bacterial Pathogens and Plant Cell death at the CRAG. \u201cIt is a fun adventure, to work in such an interdisciplinary team! Solving problems and approaching them from different perspective is the way to go\u201d affirms Anna Laromaine, from ICMAB-CSIC.<\/p>\n<p>The ICMAB and the CRAG held a joint meeting on July 2018 to find synergies between both Severo Ochoa Centers of Excellence. Maybe more fruitful collaborations will arise from it!<\/p>\n<p>\u201cPlant Healing\u201d is a Llavor Grant awarded by\u00a0<em>Els Fons Europeus de Desenvolupament Regional (FEDER)<\/em>\u00a0and the\u00a0<em>Departament d\u2019Empresa i Coneixement de la Generalitat de Catalunya<\/em>\u00a0(PLANT HEALING 2016 LLAVOR 00052)\u00a0and\u00a0\u00a0works to offer a novel material that could be implemented in current grafting protocols with no extra time or effort to significantly improve graft efficiency.\u00a0PLANT HEALING\u00a0will make an agricultural breakthrough, by developing a new nanocomposite material containing silver nanoparticles linked to\u00a0bacterial nanocellulose.
