“…Herein we present a haplotype phased reference genome and methylome of the most prominent Italian fig cultivar, Dottato, a cultivar of ancient origin, that has been cultivated in Greece since 450 BC for fresh or dried fruit consumption and introduced into southern Italy before the 6th century BC (Mafrica et al, 2015).…”

“…Therefore, the selection, conservation, and propagation of a wide range of salt tolerance genotypes is essential for the availability of new varieties and for their use in breeding programs, considering that the phenomenon of salinity is expected to increase with climate change over the next few years. In this context, few study have been conducted to assess genetic diversity among the Italian fig germplasm [22,23]. This study aims to improve the understanding of the physiological and morphological effects of salt stress at five different NaCl concentrations (0, 50, 100 and 200 mM) in two traditional fig genotypes (cvs.…”

Salinity stress represents an increasing issue for agriculture and has a great negative impact on plant growth and crop production. The selection of genotypes able to tolerate salt stress could be a suitable solution to overcome the problem. In this context, in vitro cultures can represent a tool for identifying the NaCl tolerant genotypes and quickly producing large populations of them. The possibility of exerting selection for tolerance to NaCl by using encapsulation technology was investigated in two genotypes of fig: ‘Houmairi’ and ‘Palazzo’. The effects of five concentrations of NaCl (0, 50, 100, 150 and 200 mM) added to the artificial endosperm were tested on the conversion of synthetic seeds and on the growth of derived shoots/plantlets. Moreover, proline (Pro) and malondialdehyde (MDA), the enzymatic activities of catalase (CAT), guaiacol peroxidase (POD), and EL (Electrolytic Leakage), as well as the chlorophyll content, flavanols, anthocyanins, and Nitrogen Balance Index (NBI) were determined on shoots/plantlet. The obtained results clearly showed that ‘Houmairi’ and ‘Palazzo’ could tolerate salt stress, although a strong difference was found depending on each specific physiological pathway. Indeed, ‘Houmairi’ was revealed to be more tolerant than ‘Palazzo’, with different response mechanisms to salt stress. The use of encapsulated vitro-derived explants proved to be a useful method to validate the selection of genotypes tolerant to salinity stress. Further investigation in the field must validate and confirm the legitimacy of the approach.
