Inducción y proliferación in vitro de tejidos celulares de batata (Ipomoea batatas (L.) Lam.) en medio con 2,4-D

Abstract: Con miras a contribuir con el desarrollo de un protocolo para la regeneración de plantas de batata (Ipomoea batatas (L.) Lam.) vía embriogénesis somática, se evaluó la capacidad de inducción y proliferación de tejidos celulares a partir de diferentes explantes (lámina foliar, pecíolo y la lámina foliar con el pecíolo adherido) establecidos en medio semisólido Murashige y Skoog (MS) suplido con (mg L-1) tiamina HCl (1,0), sacarosa (30.000), myo-inositol (100), agar (7.000) y cinco concentraciones de 2,4… Show more

“…There are studies where the growth dynamics of cell suspensions of sweet potato in presence of 2,4dichlorophenoxyacetic acid (2,4-D) has been evaluated by establishing growth curves, which prove that the optimal concentration to rapidly increase cell volume in culture using this plant growth regulator is 2.26 µM (0.5 mgL -1) (González et al, 2011;Guevara et al, 2012). However, handling of such culture systems from sweet potato tissues has been done for several decades (Plata et al, 2003;Konczak et al, 2003a;Konczak et al, 2003b) and anthocyanins and phenolic acids production within them has been achieved with higher concentrations of this growth regulator and with variations of growing conditions (Konczak et al, 2005).…”

“…There are also works done in universities of Córdoba and Sucre departments (Colombia) about cultivation and industrial use of sweet potato, as evidenced in the works written by Arrázola et al (2016), Andrade et al (2018), Ariza et al (2019), Jiménez et al (2019) and Arrázola et al (2020). In addition, there is a research done by Guevara et al (2012), whose results provide information on conditions for induction and proliferation callus from sweet potato leaf explants; this is a piece that could be used in subsequent biotechnological use of this plant. Unfortunately, there are no developments concerning to bioactivity evaluation, nor about isolation production of metabolites of interest from this species.…”
