In this protocol, Arabidopsis leaf explant culture is described using an adaptation of a previous method (Hu et al., 2000). Cells from the cut edges of leaf explant are able to proliferate and subsequently form calli on the callus induction medium, in which is supplemented with 2,4-D and 6-benzyl aminopurine [6-BA]. 2,4-D, one of the artificial auxin, is able to promote cell mitosis at low concentration. 6-BA, the first generation of synthetic cytokinin, plays an important role in plant cell division. 2,4-D in combination with 6-BA can effectively induce callus formation (Rashmi and Trivedi, 2014). The aim of this protocol is to analyze cell division competence of Arabidopsis plants with different genotypes. This protocol can be modified and applied to culture explants from other types of plant tissues, such as root and stem.
