Embryogenic Callus Induction

Abstract Embryogenic callus induction and regeneration are useful in many aspects of plant biotechnology, especially in the functional characterization of economically important genes. However, in sugarcane, callus induction and regeneration vary across genotypes. Saccharum spontaneum is an important wild germplasm that confers disease resistance and stress tolerance to modern sugarcane cultivars, and its genome has been completely sequenced. The aim of this study was to investigate the effect of genetic variations on embryogenic callus induction and regeneration in S. spontaneum and to screen genotypes having high tissue culture susceptibility. The study was performed using nine genotypes of S. spontaneum and the following five parameters were assessed to determine the response of genotypes to embryogenic callus induction and regeneration: callus induction, embryogenic callus ratio, embryogenic callus induction, embryonic callus regeneration and regeneration capacity. All the genotypes varied significantly (P < 0.01) in all the parameters, except for embryonic callus regeneration, which was high (>80%) for all the genotypes. High broad-sense heritability (86.1–96.8%) indicated that genetic differences are the major source of genotypic variations. Callus induction was found to be strongly positively correlated with embryogenic callus induction (r = 0.890, P < 0.01) and regeneration capacity (r = 0.881, P < 0.01). Among the nine tested genotypes, VN2 was found to be the most responsive to tissue culture and could therefore be used to characterize functional genes in S. spontaneum. We also suggested an approach with potential applications in facilitating the rapid identification of sugarcane genotypes susceptible to tissue culture.

Aquilaria malaccensis Lam. and Aquilaria subintegra Ding Hou belong to the family of Thymelaeaceae which is commonly known as gaharu or agarwood. It is a commercially important tree and identified as a potential aromatic plant. The overwhelming responses in the lodging sector reduce gaharu species in the forest. Mass propagation through plant tissue culture technology will substitute this problem. The present study was conducted to investigate the embryogenic callus induction between these two species. The most optimum sterilization method for both species was sodium hypochlorite 5.0% which gave the highest percentage of aseptic culture (95%) with the absence of tissue browning. The leaves of both species were cultured on Murashige and Skoog, (1962) (MS) media supplemented with combination of various concentrations of 6-benzylaminopurine (BAP) (0.5, 1.0, 2.0 and 2.5 mg/L) and 2,4-dichlorophenoxyacetic acid (2, 4-D) (0.5, 1.0, 1.5 and 2.0 mg/L) and kept under dark condition. The explants produced embryogenic, white and compact callus at the end cut of the explants after two weeks of culture in all treatments. The highest frequency of embryogenic callus formation was observed in explants cultured on 2.0 mg/L BAP and 0.5 mg/L 2,4-D for both species. From the present study, the optimum sterilization technique and embryogenic callus induction for A. malaccensis Lam. and A. subintegra were established.

Tissue Culture Techniques

Rubber plant (Hevea brasiliensis Muell Arg) is one of the important plantation commodities in Indonesia because of its role as a source of income. It stimulates the economic growth around the rubber plantation area. The propagation of rubber is still using conventional methods like grafting. The technique of tissue culture through callus induction is one of the alternatives of mass propagation of rubber seedling with quick and efficient time. The sterilization method is very important to determine the success of tissue culture techniques. Therefore, the aim of this research is to know the best method of sterilization and callus formation in rubber explants. The basic media used were WPM and MS, with BAP of 2 ppm and NAA 0.1 ppm. The best result of sterilization is by soaking 5% fungicide solution for 5 minutes, 5% Clorox solution for 15 minutes, betadin 10% solution for 5 minutes, and finally it rinsed with sterile water three times. The best medium uses WPM medium for callus induction, with 0.5 cm callus length and embryonic callus. In contrast, the MS medium has 0.4 cm callus length and non embryonic callus.
