“…There is also a very close link between WEPs and the cereals, fruits and vegetables that are part of our diet. This link is represented by CWR (crop wild relatives) the wild ancestors of cultivated plants which are recognized as having a strategic role for the conservation and sustainable use of plant resources in agriculture [ 32 ] also within the future scenario of climate change [ 33 , 34 , 35 ]. Creation of new product ranges for the food industry, also including functional foods, fresh or processed food with beneficial and protective properties for the body which go beyond mere nutritional properties [ 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 ].…”

Despite the large number of data published in Italy on WEPs, there is no database providing a complete knowledge framework. Hence the need to design a database of the Italian alimurgic flora: AlimurgITA. Only strictly alimurgic taxa were chosen, excluding casual alien and cultivated ones. The collected data come from an archive of 358 texts (books and scientific articles) from 1918 to date, chosen with appropriate criteria. For each taxon, the part of the plant used, the method of use, the chorotype, the biological form and the regional distribution in Italy were considered. The 1103 taxa of edible flora already entered in the database equal 13.09% of Italian flora. The most widespread family is that of the Asteraceae (20.22%); the most widely used taxa are Cichorium intybus and Borago officinalis. The not homogeneous regional distribution of WEPs (maximum in the south and minimum in the north) has been interpreted. Texts published reached its peak during the 2001–2010 decade. A database for Italian WEPs is important to have a synthesis and to represent the richness and complexity of this knowledge, also in light of its potential for cultural enhancement, as well as its applications for the agri-food system.

“…Esta gama de ambientes incluye condiciones marginales donde, si bien las líneas comerciales no se desempeñan bien, hay variedades que pueden afrontarlas, pues han estado bajo selección que conduce a la adaptación local (Dwivedi et al, 2016). De forma similar, los parientes silvestres de los cultivos tienden a tener una mayor diversidad genética, ya que no pasaron por el cuello de botella de la domesticación, que sus contrapartes domesticadas, particularmente en genes asociados con la resistencia a sequía, plagas y enfermedades (Maxted et al, 2014). A esta diversidad se puede agregar la muy amplia diversidad de microrganismos que coevolucionaron con las especies domesticadas, sus parientes silvestres y los ambientes donde se encuentran.…”

México es un centro de origen de la agricultura y domesticación de plantas. Como resultado, más de 130 cultivos son originarios de México y forman parte de un profundo entramado biocultural que permite realizar agricultura en un amplio rango de condiciones ambientales. Esta agrobiodiversidad emergió del proceso de la evolución bajo domesticación, el cual ocurrió de forma similar por miles de años, hasta el inicio de la revolución verde. A pesar de que la agricultura intensiva promovida por la revolución verde incrementó considerablemente los rendimientos y proveyó seguridad alimentaria para algunas regiones, ha tenido también consecuencias negativas al medio ambiente y a la salud humana, y además, en el caso de México, no satisface todas las necesidades de las condiciones productivas de los campesinos, considerando la heterogeneidad ambiental. Por lo tanto, es necesario buscar técnicas de producción alternativas, efectivas para cada contexto ambiental, socio-cultural y económico. Se propone una iniciativa con dos objetivos principales: 1) estudiar, conocer y conservar la diversidad genética de los cultivos nativos de México y sus parientes silvestres, y preservar el proceso de la evolución bajo domesticación que genera y mantiene dicha diversidad; y 2) utilizar esta diversidad para fortalecer la producción de alimentos y fibras de forma socialmente justa minimizando los impactos ambientales. Para cumplir estos objetivos, la iniciativa se enfoca en la fuente de variación disponible para la domesticación (diversidad genética y genómica funcional), el contexto en el que la domesticación actúa (mejoramiento y producción) y uno de sus mayores retos (cambio ambiental). La investigación en estos componentes debe enfocarse en conectar los aspectos teóricos del proceso evolutivo con aspectos prácticos de la conservación y producción. Se resumen los objetivos, retos principales y preguntas de investigación claves para cada componente, seguidos de una ruta crítica para la consolidación de esta iniciativa nacional y avances efectuados por la CONABIO.

“…Proof of this is that cultivars can already be grown in a wide variety of environments, including marginal conditions where commercial lines do not perform well ( Ceccarelli, 2009 ; Dwivedi et al, 2016 ). Similarly, crops’ wild relatives tend to have higher genetic diversity in terms of drought, pest, and disease resistance than their cultivated counterparts ( Maxted et al, 2013 ). To that diversity, we can add an even larger set of microorganisms that have co-evolved with these species and their environment.…”

An Initiative for the Study and Use of Genetic Diversity of Domesticated Plants and Their Wild Relatives

et al. 2018

Domestication has been influenced by formal plant breeding since the onset of intensive agriculture and the Green Revolution. Despite providing food security for some regions, intensive agriculture has had substantial detrimental consequences for the environment and does not fulfill smallholder’s needs under most developing countries conditions. Therefore, it is necessary to look for alternative plant production techniques, effective for each environmental, socio-cultural, and economic conditions. This is particularly relevant for countries that are megadiverse and major centers of plant domestication and diversification. In this white paper, a Mexico-centered initiative is proposed, with two main objectives: (1) to study, understand, conserve, and sustainably use the genetic diversity of domesticated plants and their wild relatives, as well as the ongoing evolutionary processes that generate and maintain it; and (2) to strengthen food and forestry production in a socially fair and environmentally friendly way. To fulfill these objectives, the initiative focuses on the source of variability available for domestication (genetic diversity and functional genomics), the context in which domestication acts (breeding and production) and one of its main challenges (environmental change). Research on these components can be framed to target and connect both the theoretical understanding of the evolutionary processes, the practical aspects of conservation, and food and forestry production. The target, main challenges, problems to be faced and key research questions are presented for each component, followed by a roadmap for the consolidation of this proposal as a national initiative.
