Naphthaleneacetic Acid Solely Induced Extensive Hairy Root Development that Precedes Extensive Shoot Regeneration from Stalk Explants of Cauliflower (Brassica Oleracea Var. Botrytis)
A reliable, rapid, and single step strategy for in vitro regeneration of true-to-type cauliflower (Brassica oleracea var. Botrytis) plants is described. Mature stalk disc explants cultured on Murashige and Skoog (MS) medium supplemented with 2 mg l-1 naphthaleneacetic acid (NAA) regenerated entire plants within one month. During the first 18 days, hairy roots developed intensively before the regeneration of shoots (on average 52 shoots per 1-cm disc explant) on the same MS medium plus 2 mg l-1 NAA.
Isolation and Structural Characterization of Glycosaminoglycans from Heads of Red Salmon (Oncorhynchus nerka)
Fuming Zhang* , Jin Xie, Robert J. Linhardt
Glycosaminoglycans (GAGs) are linear, highly negatively charged polysaccharides. They are ubiquitous molecules exhibiting a wide range of biological functions with numerous applications in pharmaceutical, cosmetic, and nutraceutical industrials. The commercial fish-processing industry generates large quantities of solid waste, which can represent a potential resource for GAG production. In this study, we used a three-step recovery and purification scheme for isolation of GAGs from the heads of red salmon (Oncorhynchus nerka).
