Plantlets of sweet potato ( Ipomoea batatas L. ) were cultured in vitro under three different ambient conditions including a standard culture room - PS, a culture room inside a glasshouse with natural light but controlled temperature - TH, and a standard glasshouse with natural light (natural fluctuations of temperature) - NP. Plantlets from three treatments were compared in terms of pathogen rate, growth, survival plant at the end of the in vitro stage and at the ex vitro acclimatization. This result showed that, after 28 days of culture, sweet potato plants were cultured in vitro TH conditions have reduced entirely due to susceptibility to fungal disease causing outside air. After 14 days of ex vitro acclimatization, plants originally grow in vitro under the TH condition had ability to adapt about field survival and growth rates better than the other two treatments.

Relevance. Currently, food products that include prebiotics, in particular, inulin, are particularly popular. Interest in this substance is justified by its valuable properties – it is a good immunomodulator, cleanses the body of toxins, radionuclides, "bad" cholesterol, promotes the assimilation of useful trace elements necessary for human life. Inulin is contained in plants such as jerusalem artichoke, chicory, as well as in sweet potatoes, the popularity of which is increasing every year. However, sweet potato plants are afraid of cold and frost-resistant. Therefore, the creation of new varieties and hybrids that are resistant to low temperatures is an urgent problem. Cellular biotechnology is aimed at solving this problem using methods of clonal microreproduction, cell selection, somatic hybridization, etc. For rapid reproduction and obtaining high-quality planting material, biotechnology methods are used, in particular, clonal micro-propagation. However, in this technology there are difficulties associated with poor adaptation of microclones to ex vitro conditions. This fact introduces an additional requirement for the selection of optimal rooting modes in vitro and ex vitro adaptation of microclones.Material and methodology. The aim of the work was to study the influence of cultivation conditions on in vitro rooting and ex vitro adaptation of I. batatas (L.) microclones. The object of the study was sweet potato microgears propagated in vitro. I. batatas micro-gears were cultured in vitro on a Murashige-Skug medium, differing by the type of auxins. The influence of red (R) and far red (FR) light on the shoots rooting in vitro and the adaptation of microclones ex vitro was studied.Results. It has been experimentally established that the cultivation of micro-gears on a medium containing indolyl butyric acid at a concentration of 0.5-1 mg/l and under conditions of illumination by LED lamps of red and far red light in equal amounts leads to the production of microclones with a well-developed root system and vegetative biomass. The use of an aeroponic installation at the last stage of clonal micro-propagation makes it possible to obtain high-quality planting material that can adapt well to open ground conditions.

The study was conducted to determine the production in vitro and in vivo of cellulases by Botrydiplodia theobromae and Rhizopus oryzae. Isolates of these organisms were obtained from the postharvest decay of sweetpotato tubers. Results revealed that B. theobrornae and R. oryzae which were isolated from postharvest spoilage of sweetpotato tubers produced endo-13-1,4-glucanase and exo-V-1 ,4-glucanase in culture and in fungi-infected tissues of sweetpotato tubers. The optimum temperature and pH for cellulose synthesis and activity were 30°C and pH 6.5, respectively.

AbstractPlants perceive and respond to volatile signals in their environment. Herbivore-infested plants release volatile organic compounds (VOCs) which can initiate systemic defense reactions within the plant and contribute to plant-plant communication. Here, for Ipomoea batatas (sweet potato) leaves we show that among various herbivory-induced plant volatiles, (E)-4,8–dimethyl–1,3,7-nonatriene (DMNT) had the highest abundance of all emitted compounds. This homoterpene was found being sufficient for a volatile-mediated systemic induction of defensive Sporamin protease inhibitor activity in neighboring sweet potato plants. The systemic induction is jasmonate independent and does not need any priming-related challenge. Induced emission and responsiveness to DMNT is restricted to a herbivory-resistant cultivar (Tainong 57), while a susceptible cultivar, Tainong 66, neither emitted amounts comparable to Tainong 57, nor showed reaction to DMNT. This is consistent with the finding that Spodoptera larvae feeding on DMNT-exposed cultivars gain significantly less weight on Tainong 57 compared to Tainong 66. Our results indicate a highly specific, single volatile-mediated plant-plant communication in sweet potato.
