In the past few years, plant-specific GRAS transcription factors (TFs) were reported to play an essential role in regulating several biological processes, such as plant growth and development, phytochrome signal, arbuscular mycorrhiza (AM) symbiosis, environmental stress responses. GRAS genes have been thoroughly studied in several plant species, b...

... further understand the evolutionary traces for the GRAS genes, we identied orthologous genes between rose and Arabidopsis and rose and rice. Total 26 and 20 GRAS orthologous gene pairs were identied between rose/Arabidopsis and rose/rice, respectively ( Fig. 3 and Table S4). We observed that each Arabidopsis GRAS gene had one to three rose orthologous genes, for instance AT5G59450 showed an ortholog relationship with the three rose genes (RcGRAS12, RcGRAS14 and RcGRAS38), it showed that some GRAS TFs in rose underwent duplication events. More number of orthologous genes between ...

... The species-specic families may be evolved from common ancestors but after the divergence of monocot and eudicot. To further explore the evolutionary relationships of GRAS members, we also carried out the synteny analyses. We observed that the number of orthologous gene pairs between rose and Arabidopsis were more than that between rose and rice (Fig. 3). It further suggested that rose is genetically closer to Arabidopsis as compared to ...

Transcriptional factors play an essential role in the regulation of developmental processes in plants. GRAS family transcription factors are plant specific, and GRAS members possess multiple functions involved in plant growth and in response to abiotic and biotic stress. The members are divided into several subgroups. This study is focused on one particular member, MtGRAS7, which belongs to the PAT subgroup. Based on constructed stable transgenic plants with a gain and loss of function of MtGRAS7, the phenotype of transgenic plants was described compared to control wild-type Medicago trucatula. The involvement of the gene in the response to abiotic stress – drought (350 mmol/L mannitol), salinity (150 mmol/L NaCl) and cold (temperature of 4 °C), was analyzed and its transcript level was detected in leaves and nodules at different time points during the exposure to stress and after the stress. The overexpression of the gene benefits plant during the stress and later on in the recovery period.
