Bananas are a staple food for over 500 million people and are also an important cash crop. Fusarium wilt, caused by the fungus Fusarium oxysporum f.sp. cubense, is one of the most destructive diseases of banana globally. Since the 1990s, an aggressive variant of this fungus, called Tropical Race 4 (TR4), severely affected banana plantations in Southeast Asia from where it spread to other continents, including Latin America, where the global banana export market is primarily centred. TR4 is a soil borne pathogen making the disease difficult to contain.

Produktbeschreibung
Bananas are a staple food for over 500 million people and are also an important cash crop. Fusarium wilt, caused by the fungus Fusarium oxysporum f.sp. cubense, is one of the most destructive diseases of banana globally. Since the 1990s, an aggressive variant of this fungus, called Tropical Race 4 (TR4), severely affected banana plantations in Southeast Asia from where it spread to other continents, including Latin America, where the global banana export market is primarily centred. TR4 is a soil borne pathogen making the disease difficult to contain.

The Joint FAO/IAEA Centre of Nuclear Techniques in Food and Agriculture implemented a Coordinated Research Project (CRP) 'Efficient Screening Techniques to Identify Mutants with Disease Resistance for Coffee and Banana" (2015-2020). This CRP brought together experts from Asia, Europe and Africa in addition to experts of the Joint FAO/IAEA Centre to develop resistance against TR4 through mutation-assisted breeding. Induced mutagenesis is particularly attractive in case of banana since most cultivated bananas are seedless, thus hampering conventional cross breeding.

This Open Access book is a compilation of the protocols developed under the CRP specifically for TR4. The first part covers methods for mutation induction, including the integrated use of innovative single-cell culture with mutagenesis techniques. The book also describes up-to-date phenotypic screening methods for TR4 resistance in banana under field-, greenhouse- and laboratory conditions. Finally, molecular and bioinformatics tools for genome-wide mutation discovery following Next Generation Sequencing are also described.

Given the imminent threat of Fusarium Wilt TR4 on banana production globally, it is our hope and intention that the book will serve as a timely reference and guide for banana breeders and pathologists worldwide who are committed to the genetic improvement of banana for Fusarium wilt resistance.

Autorenporträt
Joanna Jankowicz-Cieslak is a plant molecular biologist (and genome scientist) with over 17 years' experience in the field of molecular biology, genomics and crop improvement with the use of mutation breeding techniques. She holds a PhD in biological sciences from the Jagiellonian University, Krakow, Poland (2011) and a Habilitation degree in biology from the University of Silesia, Katowice, Poland (2019) for her work on mutation induction and functional genomics of plants of special importance in the global South. Her research is focused on the development and adaptation of new tools, protocols and guidelines for mutation induction and discovery in vegetatively propagated crops such as banana. She has extensive experience with induced mutagenesis, in vitro tissue culture, and the application of genomics tools for mutation detection in banana. She has established the first reverse genetics approach for banana and showed that induced mutations in banana are stably inherited over successive in vitro generations. She (co-) authored over 60 original research papers, monographs and book chapters as well as co-edited three protocol books. Ivan L. Ingelbrecht is involved at the Joint FAO/IAEA Centre of Nuclear Techniques in Food and Agriculture at the IAEA (www.iaea.org) as Head of the Plant Breeding and Genetics Laboratory in the coordination of R&D in the field of mutation-assisted plant breeding. Since 1994 he has worked on the development of modern biotechnology and molecular genetics tools for the improvement of banana, sugarcane, sorghum and cassava for universities and international organizations in Africa, Europe, and the USA. He has extensive expertise in R&D project management as a project lead and senior R&D Manager at the International Institute of Tropical Agriculture, Nigeria (www.iita.org) (2001-2010). His current research is focused on integrating genomics technologies with advancedcell culture and conventional mutagenesis techniques of banana, coffee and sorghum for improved food and nutrition security, climate change adaptation, and transboundary disease resistance. He has published over 80 research items, including 56 peer-reviewed journal articles, co-authored 3 books and 6 book chapters in the field of plant breeding and biotechnology. He holds a PhD in Plant Molecular Biology from Ghent University, Belgium (1993).
