“…Exposure to microplastics and nanoplastics in the ecosystem has often been reported to have adverse effects on many organisms and the environment. Negative impact on the activity of soil microorganisms and animal species [39,40]; damage to soil structure by altering the physical and chemical properties of soil [41]; adverse effect on plant growth [14,39], decreased growth and productivity of aquatic flora [42], and negative impact on nitrogen and carbon cycles [43] are some major of these effects. Microplastic pollution affects the nitrogen (N) cycle in soil ecosystems by significantly reducing NH 3 volatilization.…”

“…Agricultural soil has been recognized as a major pollutant sink for microplastics and nanoplastics that can affect ecosystem and biodiversity. Microplastics are responsible for many changes in the physicochemical properties of the soil, such as soil nutrient balance, soil porosity, fertility, aggregate stability, bulk density, enzyme activity, and water-holding capacity [14]. Many of these changes affect the soil microbiome as well as terrestrial plants.…”

“…Secondary microplastics occur in the environment as a result of the breakdown of larger plastic debris. Secondary microplastics can leach into water bodies and are significantly involved in sewers and surface water [14]. Microplastics commonly detected in the environment are polyethylene (PE), polypropylene (PP), polystyrene (PS), polyvinyl chloride (PVC), polyamide (PA), and polyethylene terephthalate (PET).…”

Plant Abiotic Stress Responses and Tolerance Mechanisms

All life forms, from the simplest to the most complicated, are inevitably exposed to altering environmental conditions in their natural habitats, gradually depending on their lifestyle. Unfavorable alterations drive these life forms either to avoidance or defense as a response. Most of the essential plant growth-promoting environmental factors can also turn out to be stress factors. Water as the most abundant molecule of all living cells can cause stress either in deficit as drought or in excess as waterlogging. Temperature is important for the maintenance of all biomolecules and metabolic reactions; hence, both low and high temperatures are deleterious stress factors. Even though the plants were exposed to various volcanic origin, heavy metals and pollutants and evolved molecular mechanisms during millions year of evolution, rapid urbanization, and industrial progress introduce brand new pollutants as micro- and nanoplastics as well as nanoparticles to plants like never before. This chapter defines and evaluates major environmental abiotic stress factors with an emphasis on the latest knowledge of molecular effects on plants. In addition, novel stress factors, such as nanoparticles and microplastics, are looked over as hot prospects for the future of plant abiotic stress areas.

“…MP impacts on primary productivities in terrestrial ecosystems have been proven beyond doubt, especially in certain ecosystems such as grasslands and agroecosystems. , Almost all soil studies agree that MP and PL controlled microbial community successions and, therefore, shifts in plant species dominance. ,, Recently, a global study on farmland ecosystems has summarized that MP have a higher impact on soil fungal communities than their bacterial counterparts, and overall microbial diversity and function of the farmland ecosystems are greatly affected via MP-induced effects on pathogen diversity . Growing evidence has pointed to changes in ecosystems structure, functions, and services due to MP and their additives in the terrestrial ecosystems .…”

Plastic debris is an established environmental menace affecting aquatic systems globally. Recently, microplastics (MP) and plastic leachates (PL) have been detected in vital human organs, the vascular system, and in vitro animal studies positing severe health hazards. MP and PL have been found in every conceivable aquatic ecosystem�from open oceans and deep sea floors to supposedly pristine glacier lakes and snow covered mountain catchment sites. Many studies have documented the MP and PL impacts on a variety of aquatic organisms, whereby some exclusively focus on aquatic microorganisms. Yet, the specific MP and PL impacts on primary producers have not been systematically analyzed. Therefore, this review focuses on the threats posed by MP, PL, and associated chemicals on phytoplankton, their comprehensive impacts at organismal, community, and ecosystem scales, and their endogenous amelioration. Studies on MP-and PL-impacted individual phytoplankton species reveal the production of reactive oxygen species, lipid peroxidation, physical damage of thylakoids, and other physiological and metabolic changes, followed by homo-and heteroaggregations, ultimately eventuating in decreased photosynthesis and primary productivity. Likewise, analyses of the microbial community in the plastisphere show a radically different profile compared to the surrounding planktonic diversity. The plastisphere also enriches multidrug-resistant bacteria, cyanotoxins, and pollutants, accelerating microbial succession, changing the microbiome, and thus, affecting phytoplankton diversity and evolution. These impacts on cellular and community scales manifest in changed ecosystem dynamics with widespread bottom-up and top-down effects on aquatic biodiversity and food web interactions. These adverse effects�through altered nutrient cycling�have "knock-on" impacts on biogeochemical cycles and greenhouse gases. Consequently, these impacts affect provisioning and regulating ecosystem services. Our citation network analyses (CNA) further demonstrate dire effects of MP and PL on all trophic levels, thereby unsettling ecosystem stability and services. CNA points to several emerging nodes indicating combined toxicity of MP, PL, and their associated hazards on phytoplankton. Taken together, our study shows that ecotoxicity of plastic particles and their leachates have placed primary producers and some aquatic ecosystems in peril.

“…The world population is expected to reach 9.6 billion by 2050, which demands a 70% increase in the world food supply. Plant diseases have become the major threat to agriculture sustainability, and continuous food supply together with other dominating threats, such as plant pests, climate change and recently loomed environmental pollution 1,2 . For instance, even the less harmful target spot disease caused 10-42% of yield losses in America despite the fact that improved agricultural practices involving cultivar selection, crop succession, and intensive use of fungicides are in place 3 .…”

Over the years, researchers have applied various deep learning techniques to automatically recognise plant diseases from both raster and spectral images. The primary focus of the existing studies is developing individual species-specific or disease-specific models, where the former recognises diseases of single crop type and the latter recognises single diseases of single or multiple crop types. Building one global model to recognise diseases of multiple crops has also been widely explored, where a class is treated as a crop-disease combination. While training individual species-specific or disease-specific deep models is labour-intensive, embracing a vast number of crop species and inherent diseases present on this planet makes the model cumbersome. In order to address this problem, a more intuitive and feasible family-based plant disease characterisation approach with botanical reasoning is proposed in this study. This approach demonstrates the feasibility of six state-of-the-art deep neural networks through a set of extensive experiments incorporating six key strategies. The results on a newly built family-based plant disease dataset confirm that the proposed novel approach is convincing to be applied in a plant family-based disease recognition problem. Further, this study creates future opportunities for more intuitive plant disease data collection and benchmark classification model development.
