This open access book is an update of genome editing techniques applied to a range of plants. We discuss the latest techniques and applications to cereals, roots and tubers, oilseed crops, fruit and forest trees, vegetables, legumes and algae including resistance to biotic and abiotic stresses, improved quality, drug production, yield and adaptation to climate change. The regulations in different countries worldwide, the patentibility and the perception by society of the applications of new genomic techniques are examined. This book is written by a multidisciplinary and multisectoral collective of high-profile scientists and other experts belonging to the COST Action network PlantEd, which is mainly European but with contributions from American, Australian, Canadian, Chinese, Indian, Iranian, Pakistani and Peruvian scientists. The book is aimed at a wide audience consisting of students, academics, private and public breeders, other actors in the food and bioeconomy value chains and policy and law makers. This is an open access book.

This open access book is a compilation of protocols developed through a Coordinated Research Project of the Joint FAO/IAEA Center of Nuclear Techniques in Food and Agriculture, specifically focused on mutation breeding for resistance to Striga. The book consists of three sections; (i) a general introduction on Striga biology and impact and mutagenesis in cereal crops; (ii) protocol chapters focusing on field, screenhouse and laboratory screening and diagnostic for resistance to Striga asiatica and S. hermonthica in sorghum, upland rice and maize, and; (iii) efficiency enhancing technologies such as rapid crop cycling, doubled haploid production and genomics for mutation discovery and marker development. These chapters were written by well recognized experts in Striga biology and physiology, and cereal breeders. The book is intended to serve as a unique reference and guide for plant breeders and geneticists engaged in breeding for resistance to Striga in cereals.

This open access book provides the first comprehensive coverage of the wheat genome sequence since the publication of the draft and reference sequences for bread wheat and durum wheat. It presents an overview and all aspects of the gold standard sequence of the bread wheat genome, IWGSC RefSeq v1.0 and its subsequent improvements through 2022 (IWGSC RefSeq v2.1), as well as the sequencing of multiple elite wheat varieties, durum wheat, and ancient wheat. The book provides a broad and extensive review of the resources, tools, and methodologies available for exploiting the wheat genome sequence for crop improvement and studying fundamental questions related to the structure, function, and evolution of the wheat genome. Wheat (Tritcum aestivum L.) is the most widely grown crop in the world, contributing approximately 20 percent of total calories and more protein in human diets than any other single source. This book is useful to students, teachers, and scientists in academia and industry interested in gaining an understanding of the wheat genome and its application as well as plant scientists generally interested in polyploid plant species.

Wie arbeiteten Botaniker abseits höfischer, universitärer und kolonialer Zentren? Am Beispiel Zürichs beleuchtet die Studie die Bedingungen für das Aufblühen der vormodernen Pflanzenkunde. Wie entwickelte sich Zürich zu einem Knotenpunkt in den transnationalen botanischen Netzwerken des 18. Jahrhunderts? Dieser Frage nachgehend leistet Meike Knittel einen Beitrag zur Erforschung der vormodernen Botanik abseits von Hafen-, Residenz- und Universitätsstädten. Johannes Gessner, der 1746 zusammen mit anderen naturkundlich Interessierten die Naturforschende Gesellschaft in Zürich gründete, deren Herbarium pflegte und sich um die Einrichtung eines botanischen Gartens in der Limmatstadt bemühte, dient dabei als zentrale Bezugsfigur für eine Untersuchung der Aktivitäten der Zürcher Pflanzenliebhaber, des Aufbaus und der Pflege ihrer translokalen Beziehungen sowie des hier koordinierten materiellen Transfers von Wissen in Form von Büchern, Herbarpflanzen und Samen. Deutlich werden dabei die ökonomischen und sozialen Verflechtungen erkennbar, die die Zürcher Botanik »aufblühen« ließen und in die Netzwerke einbanden, die sich auf dem europäischen Kontinent von Uppsala bis Pisa und von London bis Wien erstreckten und darüber hinaus bis nach Sibirien, Südafrika und Ostindien sowie in die beiden Amerikas reichten.

This open access book is only an introduction to show that radiation and radioisotopes (RI) are premier tools to study living plant physiology which leads to new findings. Who had ever imagined that we could see water in a plant? Who had ever imagined that we could see ions moving toward roots in solution? Who had ever imagined that we could see invisible gas (CO2) fixation and movement in a plant? These studies demonstrated for the first time that water, ions and gas can be visualized in living plants, which could be hardly seen by anyone before. This publication summarizes the results obtained by Nakanishi’s lab in The Univ. of Tokyo, based on her original concept and her original tools or systems. It is useful for professional scientists, plant physiologist, and those studying plant imaging. The chapters demonstrates the innovative imaging work of the author, using radioactive tracers and neutron beam to follow the absorption and transport manner of water as well as major, minor, and trace elements in plants. Through these studies the author developed a real-time macroscopic and microscopic imaging system able to apply commercially available gamma- and beta-ray emitters. The real-time movement of the elements is now possible by using 14C, 18F, 22Na, 28Mg, 32P, 33P, 35S, 42K, 45Ca, 48V, 54Mn, 55Fe, 59Fe, 65Zn, 86Rb, 109Cd, and 137Cs. The imaging methods was applied to study the effect of 137Cs following 3/11 Fukushima Daiichi nuclear plant accident, which has revealed the movements of radiocesium in the contaminated sites.
