Developmental Studies on Enzyme Histochemistry of the Three Olfactory Epithelia in the Golden Hamster

This article explores in what ways political economy as an analytical framework for developmental studies has contributed to scholarships on Indonesian’s contemporary discourse of development. In doing so, it reviews important scholarly works on Indonesian political and economic development since the 1980s. The argument is that given sharp critiques directed at its conceptual and empirical utility for understanding changes taking place in modern Indonesian polity and society, the political economy approach continues to be a significant tool of research specifically in broader context of comparative politics applied to Indonesia and other countries in Southeast Asia. The focus of this exploration, however, has shifted from the formation of Indonesian bourgeoisie to the reconstitution of bourgeois oligarchy consisting of the alliance between the politico-bureaucratic elite and business families. With this in mind, the parallel relationship of capitalist establishment and the development of the state power in Indonesia is explainable.<br>

A protocol was developed for excising and culturing cotyledon explants from mature achenes of strawberry (Fragaria × ananassa Duch.). Cotyledon explants formed callus with multiple shoot buds on agar-solidified Murashige and Skoog media containing several combinations of hormones (1 μm 2,4-D; 10 μm 2,4-D; 1 μm BA + 1 μm 2,4-D; 1 μm BA + 10 μm 2,4-D; 5 μm BA; 5 μm BA + 1 μm 2,4-D; 5 μm BA + 10 μ m 2,4-D; 5 μ m BA + 5 μm NAA; 5 μ m BA + 15 μ m NAA). After three subcultures, only tissues maintained on the medium containing 5 μm BA + 5 μm NAA continued to form shoots. Tissues transferred to other media eventually died (1 μm 2,4-D; 1 μ m BA + 10 μ m 2,4-D; 5 μ m BA; 5 μ m BA + 1 μ m 2,4-D), became unorganized (1 μm BA + 1 μm 2,4-D; 5 μm BA + 10 μm 2,4-D; 5 μm BA + 15 μm NAA), or formed roots (10 μm 2,4-D). Whole plantlets were produced by transferring callus with buds to medium lacking hormones. The rapid regeneration of clonal plantlets from cotyledon explants may be useful for reducing variability in future developmental studies. Chemical names used: N-(phenylmethyl)-1H-purin-6-amine (BA); (2,4-dichlorophenoxy) acetic acid (2,4-D); and 1-naphthaleneacetic acid (NAA).
