“…(Manivannan et al, 2007;Hussain et al, 2019). The evaluation of osmoticstress tolerance in in vitro culture media containing PEG has been proposed as an alternative to field evaluations (Gopal and Iwama, 2007;Marssaro et al, 2017;Tang et al, 2019). However, PEG has not been used in the evaluation of grapevine rootstocks.…”

“…Estos resultados permiten conocer como los explantes pueden mantenerse hidratados bajos condiciones de escasa disponibilidad de agua, es así, que en cultivares de Musa spp. permitió identificar cultivares tolerantes al estrés hídrico (Marssaro et al, 2017;Moreno-Bermúdez et al, 2015).…”

Introducción. La caracterización de cultivares de Rubus spp. tolerantes al estrés hídrico en campos experimentales es complicado por la dificultad de controlar los factores externos del medio ambiente donde son instalados. La inducción de estrés in vitro es una herramienta eficiente para estudiar los mecanismos de respuesta de las plantas y se emplea en los programas de mejoramiento para la selección de genotipos tolerantes al estrés hídrico. Objetivo. Evaluar la respuesta morfológica y fisiológica in vitro de los explantes en tres cultivares y la accesión silvestre de Rubus spp. bajo condiciones de estrés hídrico simulado con manitol. Materiales y métodos. El estudio se realizó en el Laboratorio de Biología de la Universidad Nacional Toribio Rodríguez de Mendoza de Amazonas, Perú, durante el año 2020. Se empleó un diseño completamente al azar con arreglo factorial (Factor A: cuatro genotipos y Factor B: potenciales hídricos simulados con manitol: 0, -0,2, -0,3 y -0,4 MPa) y cuatro explantes por unidad experimental. Resultados. Los cultivares respondieron de manera distinta bajo estrés hídrico simulado con manitol. Los cultivares Navaho y Tupy registraron mayor tolerancia. Conclusión. Los rasgos morfológicos y fisiológicos relacionados con la longitud de raíz, el contenido hídrico de brote, raíz y hoja permitieron identificar cultivares de Rubus spp. tolerantes al estrés hídrico simulado con manitol en la fase vegetativa.

“…Among banana improvement programs’ objectives are achieving cultivars resistant to abiotic stressors, such as salinity [ 8 , 9 ] and drought [ 10 , 11 , 12 ]. Another major challenge for the global production of Musaceae species is the development of cultivars resistant to biotic stressors, represented by their primary pests, the banana root borer ( Cosmopolites sordidus ) and the nematodes Meloidogyne spp., Pratylenchus coffeae , and Radopholus similis [ 13 , 14 , 15 , 16 , 17 , 18 , 19 ], and disease-causing pathogens, including banana bunchy top virus (BBTV) [ 20 , 21 ], Xanthomonas vasicola pv.…”

The fungus Fusarium oxysporum f. sp. cubense (FOC), tropical race 4 (TR4), causes Fusarium wilt of banana, a pandemic that has threatened the cultivation and export trade of this fruit. This article presents the first systematic review of studies conducted in the last 10 years on the resistance of Musa spp. to Fusarium wilt. We evaluated articles deposited in different academic databases, using a standardized search string and predefined inclusion and exclusion criteria. We note that the information on the sequencing of the Musa sp. genome is certainly a source for obtaining resistant cultivars, mainly by evaluating the banana transcriptome data after infection with FOC. We also showed that there are sources of resistance to FOC race 1 (R1) and FOC TR4 in banana germplasms and that these data are the basis for obtaining resistant cultivars, although the published data are still scarce. In contrast, the transgenics approach has been adopted frequently. We propose harmonizing methods and protocols to facilitate the comparison of information obtained in different research centers and efforts based on global cooperation to cope with the disease. Thus, we offer here a contribution that may facilitate and direct research towards the production of banana resistant to FOC.
