Os07g0186000
As a subgroup I h-type Trx in rice, OsTRXh1 regulates the redox state of the apoplast and influences plant development and stress responses[1][2].

Annotated Information
Function
OsTRXh1 could be secreted into the rice apoplast by transient expression and immunohistochemistry experiments. Furthermore, in the apoplast of rice, OsTRXh1 was induced by salt stress at the protein level. It has a conserved redox-active site (WCGPC), which involves in the redox status regulation of target proteins. OsTRXh1 not only had the ability to reduce insulin in the presence of DTT but also it can complement the hydrogen peroxide sensitivity of the thioredoxin-deficient yeast mutant. OsTRXh1 possesses disulfide reductase activity and could be secreted into the extracellular regions. The knockdown and overexpression transgenic plants in rice showed that it involved in salt and ABA response regulation. More hydrogen peroxide was produced in the extracellular space of OsTRXh1 knockdown plants than in wild-type plants under salt stress, whereas the OsTRXh1 overexpression plants produced less hydrogen peroxide under the same conditions,which suggesting that OsTRXh1 regulated apoplastic ROS accumulation and influenced plant stress responses in rice[1][2]. Recently, a report showed that OsTRXh1 was induced by cold stress and negatively regulated the kinase activities of Oryza sativa Mitogen-activated Protein Kinase3 (OsMPK3) and OsMPK6 in vitro through a redox-dependent mechanism[3].
