“…During the first phase of the CASS project, and similar to the Bill & Melinda Gates Foundation‐supported project African Cassava Whitefly (Perez‐Fons et al ., 2019), considerable optimization of methods for metabolite profiling was required. This resulted in standard operating procedures across projects for metabolite and starch quality assessments in different cassava tissues (Rosado‐Souza et al ., 2019) and for enzyme activity measurements (Arrivault et al ., 2019). In addition, six African cultivars of cassava were grown either in the greenhouse (at the University of Erlangen, Germany) or in the field (at the International Institute for Tropical Agriculture, Ibadan, Nigeria) to analyze source leaves, sink leaves, stems, and storage roots during storage root bulking for their metabolite, ion, and enzyme content (Obata et al ., 2020) and to establish a procedure for unmanned aerial vehicle (UAV)‐based quantification of the three‐dimensional canopy structure and its dynamical changes throughout the season (Van Doorn et al ., 2020).…”
