“…On the other hand, explant density does not show signi cant statistical differences for the variables shoot length and number of leaves. Similar results are reported byMonja et al (2021) in micropropagation of Agave angustifolia, who indicate that the inoculum of 20 and 40 explants per TIB bioreactor does not in uence the growth rate of shoots and number of leaves. In some cases, the inoculum density is not decisive in physiological and morphological terms, but it is decisive in economic terms, since a low inoculum density causes a lower e ciency in the use of nutrients in the culture medium and waste of resources, with a consequent increase in the cost of seedlings (Uman et al 2021).In this study, the TIB system does not increase the number of shoots per explant of C. palmata, but it is determinant to obtain greater shoot length, number and length of roots, number of leaves and dry weight.…”

Carludovica palmata is a neotropical plant with a promising potential for the agroindustry. It is an important source of fibers used to manufacture hand-made goods. Colombia is one of the leading countries in the production this species, however, it lacks efficient techniques for its propagation. We developed a protocol for massive micropropagation of C. palmata using Temporary Immersion Bioreactor (TIB) system. Immersion frequency, immersion times, culture medium volume, and explant density were evaluated using a split-split-plot design. The variables evaluated were number and length of shoots and roots, number of leaves, and explants dry weight. The performance of three micropropagation systems, BIT, semi-solid medium, and liquid medium, were evaluated using generalized randomized block design. Murashige and Skoog (MS) culture medium with 1,0 mg L− 1 of 6-Benzylaminopurine, 0,5 mg L− 1 of 1-Naphthaleneacetic acid, and 20 g L− 1 of sucrose added to it was used. Results obtained was frequency 12 h with immersion time 1 min improved the length of both shoots and roots, as well as the number of leaves and dry weight. Volume of 20 ml/explant was found to be adequate condition to increase the number and length of shoots, the number of leaves, and the dry weight. According to the optimization module, the factors levels that will maximize the evaluated variables are immersion frequency 12 h and immersion time 1 min, with 175 mL of culture medium per bioreactor and density of 10 explants. In conclusion, TIB was shown to be efficient for massive micropropagation of C. palmata compared with conventional methods.

“…Independently of the regeneration response, micropropagation may also be combined with various methodologies for mass propagation. The most common system is semisolid culture, although there are additional techniques, such as temporal immersion systems and thin cell suspension layers, that are suitable options for enhancing the number and quality of shoots/somatic embryos obtained [34,35]. Table 2 summarizes in detail research on Agave micropropagation, focusing on reports since 2000 onwards.…”

The Agave genus is composed of approximately 210 species distributed from south United States to Colombia and Venezuela. Numerous Agave species have been used for the preparation of alcoholic beverages and have attracted interest in the pharmaceutical and food industry. Despite their economic importance, there are few initiatives for the improvement and selection of characteristics of interest. This is mainly due to its morphology, long lifecycles, and monocarpic nature. Micropropagation is a feasible alternative to the improvement of Agave species. It has been used for multiple purposes, including massive propagation, induction of somaclonal variation to enhance agronomic characteristics of interest, maintenance of specific genotypes, and genetic transformation using molecular techniques. In this report, we summarize the most outstanding findings regarding the micropropagation of Agave species mediated by multiple regeneration responses. We also describe the media and growth regulators for each of the previously described methods. In addition, we discuss how micropropagation has allowed the development of transformation protocols. Exploitation of this technology may be a feasible strategy to introduce genes and improve certain traits. Genetic transformation also offers an opportunity for studying molecular mechanisms. This represents advantages for optimizing production in the field and for implementing breeding programs.

“…Also, this technique allows ensuring the obtained food does not represent a risk to human or environmental health (Loyola-Vargas and Ochoa-Alejo, 2012;Thorpe, 2012). However, in Mexico there have been studies on micropropagation on several crop, as Physalis angulate, Agave angustifolia and Carica papaya (Ramiréz-Hernández et al 2021;Monja-Mio et al, 2021;Romo-Paz et al, 2021).…”

Background: The COVID-19 pandemic evidenced the fragility of the agri-food sector by affecting the food supply chains which directly depend on the health of its main actors. In this context, countries need to rethink the agricultural production models, considering environmental and human health as priorities to achieve food safety. Aim: Systematically review the state of the art regarding the role of agricultural genetic resources as a source of resilience in the face of events such as the present pandemic as a point of reflection for the identification of opportunities for the restructuring of regional agriculture sensitive to nutrition for health. Methodology: Exhaustive search and analysis of documentary information regarding the effects of COVID-19 on the agri-food sector and the role of agricultural genetic resources in the current pandemic were conducted. Then, through an analysis of the occurrence and association of the main terms addressed in the literature considered, the thematic axes were drawn to address the central discussion of the systematic review. Results: Terms co-occurrence analysis corroborated the relevance and pertinence of the topic addressed. Additionally, the importance of the conservation of agricultural genetic resources and implementation of sustainable agriculture models, as a source of resilience to pandemics, was visualized. The discussion addressed the impact of the pandemic on the Mexican agri-food sector and the restructuring of post-COVID-19 agriculture through the nation and nutrition-sensitive agriculture for health approaches. Implications: The exhaustive analysis of the relationship COVID-19-agricultural genetic resources-health in Mexico highlights the need for the generation of agricultural policies and the increase in multidisciplinary research that favors biodiversity as a source of sustainability, productivity, and health for agroecosystems and the welfare of humanity. Conclusions: A fatalistic scenario for humanity seems to be dissipating in the face of the possibilities of rethinking the economic, social, and agricultural systems from the approaches of the nation and nutrition-sensitive agriculture for health, where, through the responsible use of agricultural resources it is possible to rebuild an agri-food production system with a tendency to resilience to events such as the current pandemic caused by the COVID-19 disease.
