“…In total the hexamer contains about 1,200 amino acids with an approximate molecular mass of 130 kDa (Lane 2002). This is contrasted by the discovery of a single copy GLP from rice that has SOD-activity in its dimeric form (Banerjee and Maiti 2010).…”

“…Six germin subfamilies (GER1-6) were characterised in Druka et al (2002) with varying enzymatic activities e.g. OXO action in GER1 ('true germin' proteins) and SOD activity in GER2 (Banerjee and Maiti 2010), GER4 and GER5 sub-families. The GER1 subfamily has also been shown to be important for germination and early plant development in plants (Federico et al 2006).…”

The recent release of the genome sequences of a number of crop and model plant species has made it possible to define the genome organisation and functional characteristics of specific genes and gene families of agronomic importance. For instance, Sorghum bicolor, maize (Zea mays) and Brachypodium distachyon genome sequences along with the model grass species rice (Oryza sativa) enable the comparative analysis of genes involved in plant defence. Germin-like proteins (GLPs) are a small, functionally and taxonomically diverse class of cupin-domain containing proteins that have recently been shown to cluster in an area of rice chromosome 8. The genomic location of this gene cluster overlaps with a disease resistance QTL that provides defence against two rice fungal pathogens (Magnaporthe oryzae and Rhizoctonia solani). Studies showing the involvement of GLPs in basal host resistance against powdery mildew (Blumeria graminis ssp.) have also been reported in barley and wheat. In this mini-review, we compare the close proximity of GLPs in publicly available cereal crop genomes and discuss the contribution that these proteins, and their genome sequence organisation, play in plant defence.

“…On the basis of various enzymatic activities, six germin subfamilies (GER1-6) have been described. GER1 (true germin proteins) has been shown to possess OXO activity, while GER2 has been shown to possess superoxide dismutase (SOD) action (Banerjee and Maiti, 2010). It has also been shown that the GER1 subfamily is important for early plant development and germination in plants (Federico et al, 2006).…”

IntroductionGermins and germin-like proteins (GLPs) belong to the cupin superfamily of proteins, identified in several plants, including monocot, dicot, gymnosperms, Physarum polycephalum, and myxomycete (slime mold), after initial discovery of a protein marker germin in the germination of wheat seeds. Germin relatives have also been recognized in animals, prokaryotes, and fern spores (Lu et al., 2010).Germins and GLPs present major problems in classification due to their high sequence conservation in multiple plant species (Dunwell and Gane, 1998). A strong classification system is established by structural characteristics of these proteins due to the clustering of proteins with conserved functions (Agarwal et al., 2009). The proteins that have oxalate oxidase (OXO) enzymes activity, exclusively found within cereal plant species, are placed in a well-conserved homogeneous group called true germins (Carrillo et al., 2009;Davidson et al., 2009), while the germin-motif comprising proteins with an average of 50% amino acid sequence identity that either do not have OXO action or have not yet been allotted an enzymatic function are placed in a heterogeneous group called germinlike protein (Dunwell et al., 2008;Breen and Bellgard, 2010).To date, major research on germins and GLPs has been conducted on cereal plants, especially wheat, maize, barley, and rice. On the basis of various enzymatic activities, six germin subfamilies (GER1-6) have been described. GER1 (true germin proteins) has been shown to possess OXO activity, while GER2 has been shown to possess superoxide dismutase (SOD) action (Banerjee and Maiti, 2010). It has also been shown that the GER1 subfamily is important for early plant development and germination in plants (Federico et al., 2006). The GLPs with mostly unknown function in plant genomes have been classified into subfamilies Thornburg, 1999, 2000). In contrast to a true germin subfamily, both GLP1 and GLP2 subfamilies are limited to proteins of SOD action, while GLP3 is involved in phosphodiesterase activities. However, recently more subdivisions were suggested (Breen and Bellgard, 2010). A key feature of the germin and GLP subdivisions was the conservation of a motif derived from that of the cupin superfamily (Carter and Thornburg,

“…GLPs are also responsible for growth and development, as well as cellular anatomy. GLP1 from rice affects plant height, disease resistance, and maintenance of cell dimensions (Banerjee and Maiti, 2010). Genes encoding GLPs are overexpressed in Prunus salicina fruit when treated with auxins (El-Sharkawy et al, 2010), and another member from Arabidopsis (GLP4) binds auxins in vitro (Yin et al, 2009).…”
