Book Description
Duckweed (Lemnaceae) represents a small aquatic monocot plant family presently composed of 36 species. These plants gained importance in recent decades for their applications in wastewater purification, as animal food or human nutrition, as well as for energy production. This Reprint presents 39 manuscripts published in the Special Issue "Duckweed: Research meets applications" of the journal Plants. We provide an overview of the present state of the art of duckweed research in taxonomy of the family, phytoremediation, accumulation of protein or starch, interaction with microorganisms, and phytomonitoring of toxic compounds. This Special Issue also invited the participants of the 6th International Conference on Duckweed Research and Applications (ICDRAs) held in Gatersleben, Germany, organised on behalf of the International Steering Committee on Duckweed Research and Applications (ISCDRAs). This Reprint is organised as follows: 1. Introduction; 2. Molecular Characterization and Taxonomy; 3. Phytoremediation: Wastewater; 4. Applications: Accumulation of Protein or Starch; 5. Interaction with Microorganisms; 6. Physiology and Phytomonitoring. The manuscripts were organised by the Guest Editors Viktor Oláh (University of Debrecen, Debrecen, Hungary), Klaus-J. Appenroth (Friedrich Schiller University, Jena, Germany), and K. Sowjanya Sree (Central University Kerala, Periye, India).

Book Description
Global demand for food is rising as a result of increases in the global population as well as dietary changes. Furthermore, climate change exerts additional pressure on the food supply, adversely affecting sustainable food production. Increased temperatures and drought stresses coupled with the migration of pests limit crop yields and affect their nutritional quality. Many staple crops are unable to adapt to these changing climatic conditions. To achieve the Sustainable Development Goals of the United Nation to end hunger and promote good health and well-being, concerted efforts need to be made to enhance food production while mitigating the effects of climate change through the promotion of climate-smart agricultural practices and the utilization of neglected and underutilized crop species. These species can be highly nutritious and well-adapted to different agroecologies and climatic conditions, meaning that they offer the possibility of improving food and nutritional security.

Book Description
This book tells the story behind the first Spirodela genome sequencing project. Further, it describes the current genomics applications of these findings, and efforts to sequence new genomes within the family. The closing chapters address the sequencing of the over 1 Gigabase Wolffia genomes, which could have major impacts on genome evolution and agricultural research. The duckweed or Lemnaceae family is a collection of 5 genera and 37 species of the smallest, fastest-growing flowering plants. Many of these aquatic monocotyledonous plants can grow all over the world, in a variety of climates. Given their simplified and neotenous morphology, duckweeds have been researched for several decades as a model species for plant physiology and ecotoxicological research, contributing to our understanding e.g. of flowering response, plant circadian systems, sulfur assimilation pathways and auxin biosynthesis. In addition, duckweed-based treatment has been a favorite and feasible means, especially in developing countries, of removing phosphorus and pharmaceutical chemicals from sewage and wastewater. With a dry annual mass yield per hectare of up to 80 tonnes (equivalent to 10 tonnes of protein), duckweed is also a promising aquatic crop in new modern and sustainable agriculture. Besides being an excellent primary or supplemental feedstock for the production of livestock and fish, duckweed biomass can be utilized as a potential resource for human nutrition, biofuel, or bioplastics, depending on water quality as well as protein or starch accumulating procedures. These academic and commercial interests have led to international efforts to sequence the Spirodela polyrhiza genome, the smallest and most ancient genome in the family.

Book Description
My thesis provides the first whole genome analysis of an aquatic plant, Spirodela polyrhiza and a reference genome for a new order among the monocotelydonous angiosperms. The Lemnoideae belong to the order of the Alismatales and are commonly known as duckweeds, the smallest, fastest growing, and simplest of aquatic plants, thus telling them apart is not a trivial task. Whereas a simple and accessible protocol has been established for land plants by the Consortium for the Barcode of Life with seven universal DNA barcoding markers, we found that atpF-atpH noncoding spacer is the most promising marker for duckweed species-level identification. Furthermore, our assembly and annotation of the Spirodela chloroplast and mitochondrial genomes open an opportunity of population-level classification. A key to our understanding of the evolution of a species and its potential use is the gene content of the organism. Therefore, we sequenced Spirodela polyrhiza 7498 that has one of the smallest genomes with 158 Mb within this subfamily of species. The genome contains 19,623 predicted protein-coding genes, sharing a total of 8,255 common gene families with Arabidopsis, tomato, banana, and rice despite a significantly reduced gene number. Reduced gene families and missing genes reflect changes consistent with its compact and reduced morphogenesis or forever-young life style, aquatic suspension, and suppression of juvenile-to-adult transition. Spirodela exhibits a remarkable phenotypic plasticity to adapt to cold weather in winter. We identified and functionally annotated 362 differentially expressed genes, which open a major step towards understanding the molecular network underlying vegetative frond dormancy. Moreover, the expression data for lipid and starch biosynthesis together with the turion-specific transcriptional genes from our RNA-Seq data could be ideal targets to develop duckweeds into oil crops. Thanks to its unique and fascinating biology, applications of duckweed in water remediation and as a renewable energy source are predicted to have a bright future. The genome sequence of Spirodela provides the first step to identify, understand, and improve relevant traits for specific target applications.
