About this Research Topic
Some genotypes of food plants including potatoes, rice grains and many leafy vegetables are good accumulators of high levels of toxic metals such as cadmium. There is a growing demand for the identification and development of food-safe plant cultivars. A key to making progress towards this goal lies in a better understanding of metal uptake in the roots, subsequent translocation, partitioning and resistance in food plants.
Some trace metallic elements such as iron and zinc are associated with another public health issue, namely the problems arising from their potential deficiencies in human dietary intake. The same elements are also normally essential for plant growth and plants have the natural abilities to accumulate them. A key to biofortification of food plants with increased levels of the desirable trace elements (for humanity) without the toxicity consequences to the plants again rests on a better understanding of the uptake of these elements and tolerance or detoxification strategies used by variant food plants.
Clearly, this research topic is a common key fundamental to advances in all of the three above-mentioned areas of investigations. The aim is to bring together the novel findings from all the three areas in the same resource rather than to treat each area as a separate topic. It is anticipated that this will enable quick snap shots of the three related areas at a glance.
Submission of manuscripts (original research, theories and opinions, mini reviews and reviews) is warmly welcome. In particular, this research topic will be a collection of manuscripts by researchers active in the fields of phytoremediation, biofortification and development of food-safe plant cultivars who are: (a) exploiting the power of diverse approaches including genome wide analysis, advanced microscopic and imaging tools, mutant isolation and characterization in model experimental as well as food plants, genetic engineering, and plant breeding to gain new insights about metal uptake and resistance in plants, (b) exploring new mitigation measures, including chemical, microbial, environmental and soil manipulations, against metal toxicity in plants, and (c) probing the cross-talks among plant hormones, antioxidants and other signalling molecules in relation to metal uptake and resistance in plants.
Important Note: All contributions to this Research Topic must be within the scope of the section and journal to which they are submitted, as defined in their mission statements. Frontiers reserves the right to guide an out-of-scope manuscript to a more suitable section or journal at any stage of peer review.
