The germin protein family is comprised of two main subgroups in plants, oxalate oxidases (OXOs) and germin-like proteins (GLPs). These proteins are implicated in a variety of plant processes including germination, development, pollen formation, and response to abiotic and biotic stress. Here, we examine the phylogenetic relationships and functional diversity of the germin gene family across div...

The members of plants response various internal and external signals differently. The responses of plants to biotic and abiotic stress factors involve biochemical, physiological, morphological and developmental changes. Among the various circumstances salt stress is particularly under extensive studies due to low salt tolerance of crop plants. Germin and germin-like gene products were previousl...

a proteomic approach was conducted to further understand the mechanism of plant responses to salinity in hordeum bulbosom. three-week-old seedlings were treated with 300 mm of nacl for 21 days. total proteins of fourth leaf were extracted and separated by two-dimensional gel electrophoresis. more than 500 protein spots were reproducibly detected, including 46 spots that were up-regulated and 16...

responses of plants to salinity stress and development of salt tolerance are extremely complex and various mechanisms appear to be involved. we employed a proteomic approach to study the mechanism of plant responses to salinity in a sensitive cultivar of barley (527 line). three-week-old seedlings were treated with 300 mm nacl for 3 weeks. total proteins of fourth leaf were extracted and separa...

The cDNAs encoding three germin-like proteins (PsGER1, PsGER2a, and PsGER2b) were isolated from Pisum sativum. The coding sequence of PsGER1 transiently expressed in tobacco leaves gave a protein with superoxide dismutase activity but no detectable oxalate oxidase activity according to in-gel activity stains. The transient expression of wheat germin gf-2.8 oxalate oxidase showed oxalate oxidase...

In the current study, the biosynthesis of germin was determined in the organs of wheat embryos during germination. The temporal and spatial determination of germin protein was carried out by employing an anti-germin sera in gel-blot analysis. Germin was detected in the coleoptile, roots and vascular transition region of and 6-day-old germinated wheat seedlings. It was shown that the leaf tissue...

Germin gene expression in barley (Hordeum vulgare L.) seedlings responds to developmental and environmental cues. During seed germination, germin mRNA levels were maximal 2 d after the start of imbibition in control seedlings and declined to low levels by 6 d. When seeds were sown in the presence of 200 mM NaCl, germin mRNA levels were also maximal after 2 d, but NaCl treatment, which slowed se...

Germin, a molecular marker of wheat embryo germination, is a remarkably proteaseresistant, apoplastic, homopentameric glycoprotein. Different forms of germin found to be related to various aspects of plant development have been discovered. Germins were determined in cereals, dicotyledonous angiosperms, gymnosperms and in a prosit, all these proteins are together called germin-like proteins due ...

The response of plants to biotic and abiotic stress factors involves biochemical, physiological, morphological, and developmental changes. Salt stress has been the subject of extensive studies due to the low salt tolerance of many crop plants. Germin and germin-like gene products are known to be involved in various aspects of plant development, such as defense, embryonic development and respons...
