“…avoid crossed pollination and they are eradicated to establish organic coffee plantations [104]. The improvement of different varieties that replaced old landraces produced genetic erosion, increased the incidence of pests and diseases due to the lack of genetic diversity within the cucurbit gene pool and abiotic stress [107] [108]. The genetic erosion of chayote is boosted through the inbreeding and usage of cloned plants in orchids increasing the incidence of viruses and fungal plants infected [101].…”

Cucurbitaceae family contains important economic and medical crops, they can be divided into two categories according to the worldwide consumption, use, and production. The Cucurbit Popular Crops (CuPoC) are comprised of cucumber, the Cucurbita group (pumpkin and squash), melon and watermelon. On the other hand, Neglected and Underutilized Cucurbit Species (NU-CuS) group has been used as food sources, medicinal properties and elements in the elaboration of different types of items. The NUCuS is represented in this review work by bitter gourd, bottle gourd, chayote, ridge gourd, and snake gourd, which are recognized mainly in Asia. The center of origin of the majority of NUCuS was proposed to be in the Old World. In contrast, the origin of chayote or Sechiumedule (Jacq.) Sw. was suggested in the New World, precisely in Mesoamerican region based on linguistic uses and distribution of wild relatives. The environmental factors along with artificial selection, production systems and traditional knowledge have been influenced the evolutionary history of NUCuS, Infraspecific variation of chayote has been reported in Mexico over-described varietal groups. These descriptors were determined based on biochemical and morpho-structural traits; however, cytogenetic analyses are scarce. Specifically, chromosome and nuclear content analyses are important to support botanical groups, analyze artificial selection history, developing breeding and conservation programs. The present review paper discusses agronomic and evolutionary importance based on cytological evidence in NUCuS, mainly in the prominent chayote; with the perspective to prompt breeding, conservation, cytology, structural and functional genomics research for its sustainable utilization.

Only a systems approach, that studies not only the single components, but also considers the interplay among them, can, in fact, indicate sustainable strategies to face the multiple challenges before humanity (Sonnino, 2017).

Climate change is an unequivocal fact and its impacts are already perceptible today. Climate change will profoundly alter the present conditions of agriculture in almost all countries with variable severity from region to region. On one hand unpredicted changes in climatic parameters are likely to threaten the production and productivity of economically important plant species particularly that of food crops, at the same time agriculture productivity requires significant increase to meet the expected growth in demand for food by the ever increasing world population. Conservation and sustainable use of diversity present in plant genetic resources and traditional knowledge of germplasm within and among plant species represent economic, scientific and societal value which has tendency to solve the food security problems erupt due to expanding global population. An advance made in biotechnology field such as in vitro culture technology, cryopreservation and molecular markers technology has generated significant contributions to improve the methods of conservation of rare and endangered plant genetic resources and traditional knowledge of germplasm and their valuable management in an effective way. A strategic and forward vision for conservation of plant genetic resources and traditional knowledge of germplasm and sustainable use of plant resources in the 21st century is of far reaching significance for sustainable development.

“…The SI includes three thematic reviews that guide readers through the main recent scientific [2], technological [3], and legal [4] developments for the characterization, conservation, and use of plant genetic resources. The source of diversity as well as the approaches to its use can be different.…”

The rapid progress and increasing affordability of novel investigation tools in plant genetics and biotechnology offer previously inaccessible opportunities for the exploitation of plant genetic diversity in agriculture. The Special Issue was lunched to highlight how new technologies are improving both genotyping and phenotyping methods, thus allowing us to uncover crop diversity and use genetic variability for plant breeding with remarkable precision and speed. Three thematic reviews report on scientific, technological, and legal advances in plant diversity and agriculture. Three contributions provide specific examples of the exploitation of different kinds of genetic resources, ranging from landraces to mutant populations. Six research articles are illustrative examples of the study of molecular and/or phenotypic diversity to address basic or applied questions in different plant species. Finally, this SI was also launched to honor the memory of Prof. Gian Tommaso Scarascia Mugnozza and a dedicated Editorial acknowledges his work in plant breeding and biodiversity protection.
