Germin with oxalate oxidase and superoxide dismutase activity is a homohexamer of six manganese-containing interlocked beta-jellyroll monomers with extreme resistance to heat and proteolytic degradation [Woo, E.-J., Dunwell, J. M., Goodenough, P. W., Marvier, A. C. & Pickersill, R. W. (2000) Nat. Struct. Biol. 7, 1036-1038]. This structure is conserved in germin-like proteins (GLPs) with other ...

To study the mechanisms of inducible disease resistance in conifers, changes in transcript accumulation in roots of Norway spruce (Picea abies (L.) Karst.) seedlings exposed to the root rot pathogen Ceratobasidium bicorne Erikss. and Ryv. (anamorph: Rhizoctonia sp.) were monitored by differential display (DD). Because C. bicorne attacks root tips, a desiccation treatment was added to exclude ge...

Germination is a process which characterized with nescient synthesis of genes. Among the genes synthesized during the germination of wheat embryos, germin genes, proteins and their enzymatic activity were defined. Germin is a water soluble homopentameric glycoprotein which is remarkable resistant to degradation by a broad range of proteases including pepsin. Germin proteins found to have strong...

Germin and germin-like proteins (GLPs) are water soluble extracellular proteins reportedly expressed in response to some environmental and developmental signals. Some enzymatic activities have also been associated with germin/GLPs. However, their role in overall metabolism has not been fully understood. Significant insight into their function may also be gained by analysis of their promoter. Du...

Molecular investigations during wheat germination have revealed unique developmentally regulated proteins, designated as germins, which show remarkable resistance to broad specificity proteases and to dissociation in SDS. Germins in cereals have an oxalate oxidase activity, which generates H2O2 from the oxidative breakdown of oxalate thereby playing a significant role in plant development and d...

Oxalate oxidases (OXOs) have been found to be concentrated in the surface tissues of wheat embryos and grains: germin is concentrated in root and leaf sheaths that surround germinated embryos; pseudogermin (OXO-psi) is concentrated in the epidermis and bracts that 'encircle' mature grains. Most strikingly, the epidermal accumulation of OXO-psi was found to presage the transition of a delicate '...

BACKGROUND Silkworm fecal matter is considered one of the richest sources of antimicrobial and antiviral protein (substances) and such economically feasible and eco-friendly proteins acting as secondary metabolites from the insect system can be explored for their practical utility in conferring broad spectrum disease resistance against pathogenic microbial specimens. METHODOLOGY/PRINCIPAL FIN...

Germin-like proteins (GLPs) have several proposed roles in plant development and defence. Two novel genes (Ps-GLP1 and 2) encoding germin-like protein were isolated from plum (Prunus salicina). Their regulation was studied throughout fruit development and during ripening of early and late cultivars. These two genes exhibited similar expression patterns throughout the various stages of fruit dev...
