Plant Sciences in Agriculture
Plant pathogens Microorganisms, also called as microbes, live in every part of the biosphere, including soil, water, and air. Plant pathogens are the microbes that infect plants and cause diseases. In history, some plant diseases led to tremendous negative impacts on society. In 1845, potato blight disease was prevalent in all potato growing regions in Ireland. Phytophthora infestans, a fungus, ...

Playing hide and seek below the soil
Below the soil of a diverse grassland area you’ll find a jungle of plant roots. It is also home to a wide variety of bacteria and fungi, of which some are pathogenic and looking for a host in the tangle of roots. It appears that this is much more difficult when there is a larger diversity of plants as the host plant is more able to hide among the varied crowd. Greater plant diversity ...

Effects of bisphenol a on key enzymes in cellular respiration of soybean seedling roots
Environmental endocrine disrupter–bisphenol A (BPA) is ubiquitous in the environment, with potential toxic effects on plants. Previous studies found a significant effect of BPA on levels of mineral nutrients in plant roots, but the underlying mechanism remains unknown. To determine how BPA influences root mineral nutrients, the effects of BPA (1.5, 3.0, 6.0, 12.0, 24.0, 48.0 and 96.0 mg L−1) ...

Accumulation of contaminants of emerging concern in food crops, part two: Plant distribution
Arid agricultural regions often turn to using treated wastewater (reclaimed water) for irrigation of food crops. Concerns arise, however, when considering the potential for persistent contaminants of emerging concern (CECs) to accumulate into plants intended for human consumption. This work examined the accumulation of a suite of nine CECs into two representative food crops, lettuce and ...

Combined effects of bisphenol A and cadmium on growth and nitrate assimilation of soybean seedling roots
Bisphenol A (BPA) and cadmium (Cd) pollution exist simultaneously in many regions. However, little information is available regarding the combined effects of BPA and Cd pollution on plants. Plant roots are in direct contact with the soil, which is an important compartment of BPA and Cd. Here, the effects of combined BPA and Cd pollution on soybean seedling roots were evaluated in pot ...

The rhizotoxicity of metal cations is related to their strength of binding to hard ligands
Mechanisms whereby metal cations are toxic to plant roots remain largely unknown. Aluminum, for example, has been recognised as rhizotoxic for about 100 years but there is no consensus on its mode of action. We contend that the primary mechanism of rhizotoxicity of many metal cations is non‐specific and that the magnitude of toxic effects is positively related to the strength with which they ...
