Genome-Wide Identification and Bioinformatics Analysis of the FK506 Binding Protein Family in Rice.

The FK506 Binding Protein (FKBP), ubiquitously present across diverse species, is characterized by its evolutionarily conserved FK506 binding domain (FKBd). In plants, evidence suggests that this gene family plays integral roles in regulating growth, development, and responses to environmental stresses. Notably, research on the identification and functionality of FKBP genes in rice remains limited. Therefore, this study utilized bioinformatic tools to identify 30 FKBP-encoding genes in rice. It provides a detailed analysis of their chromosomal locations, evolutionary relationships with the Arabidopsis thaliana FKBP family, and gene structures. Further analysis of the promoter elements of these rice FKBP genes revealed a high presence of stress-responsive elements. Quantitative PCR assays under drought and heat stress conditions demonstrated that genes OsFKBP15-2, OsFKBP15-3, OsFKBP16-3, OsFKBP18, and OsFKBP42b are inducible by these adverse conditions. These findings suggest a significant role for the rice FKBP gene family in stress adaptation. This research establishes a critical foundation for deeper explorations of the functional roles of the OsFKBP genes in rice.

Suppression of OsSAUR2 gene expression immobilizes soil arsenic bioavailability by modulating root exudation and rhizosphere microbial assembly in rice.

One of the factors influencing the behavior of arsenic (As) in environment is microbial-mediated As transformation. However, the detailed regulatory role of gene expression on the changes of root exudation, rhizosphere microorganisms, and soil As occurrence forms remains unclear. In this study, we evidence that loss-of-function of OsSAUR2 gene, a member of the SMALL AUXIN-UP RNA family in rice, results in significantly higher As uptake in roots but greatly lower As accumulation in grains via affecting the expression of OsLsi1, OsLsi2 in roots and OsABCC1 in stems. Further, the alteration of OsSAUR2 expression extensively affects the metabolomic of root exudation, and thereby leading to the variations in the composition of rhizosphere microbial communities in rice. The microbial community in the rhizosphere of Ossaur2 plants strongly immobilizes the occurrence forms of As in soil. Interestingly, Homovanillic acid (HA) and 3-Coumaric acid (CA), two differential metabolites screened from root exudation, can facilitate soil iron reduction, enhance As bioavailability, and stimulate As uptake and accumulation in rice. These findings add our further understanding in the relationship of OsSAUR2 expression with the release of root exudation and rhizosphere microbial assembly under As stress in rice, and provide potential rice genetic resources and root exudation in phytoremediation of As-contaminated paddy soil.

Asian Hate, religion, and perceived changes in physical health: exploring the flip side of minority stress during the COVID-19 pandemic.

OBJECTIVES: Prior research suggests that racism is associated with adverse mental health outcomes for Asians in the United States. Relatively less research has been conducted to examine the effects of racism on physical health, particularly the changes in physical health among Asians and Asian Americans. This study aims to fill in this gap in prior research. DESIGN: Survey was conducted via Qualtrics in March 2023. A panel sample of 356 Asian and Asian American adults from across the US was collected. Ordinary Least Squares Regression was employed to examine the interrelationships among racism, religion, and perceived changes in physical health during the COVID-19 pandemic. RESULTS: Contrary to conventional wisdom, more frequent experience with blatant racism was associated with a perceived improvement in physical health after controlling for subtle racism, anxiety, acculturation, and various sociodemographic variables. Interestingly, this robust relationship was more significant among Asians who attended religious services more frequently. Additional three-way interactions revealed that the interaction between blatant racism and religious service attendance on perceived changes in physical health was more significant for US-born Asians and Asians of Indian or Japanese ethnicity. CONCLUSION: Racism exerts a significant influence on physical health outcomes among Asians and Asian Americans. However, this relationship was contingent upon the specific aspect of racism and intersected with religiosity, acculturation, and ethnic identity.

Is Asian Hate Just About Race? Religious Discrimination and Smoking Among Asian and Asian American Adults in the USA.

Prior research has shown that experiencing religious discrimination is tied to adverse physical and mental health outcomes. However, less known is whether or not religious discrimination may influence one's risk of smoking. In particular, there is a paucity of research examining the impacts of religious discrimination on smoking for Asians in the United States, whose experience of religious discrimination is heavily racialized. To fill in these gaps, in this study, 356 Asian and Asian American adults living in the US were surveyed. The key results suggest that perceived religious discrimination was associated with a higher risk of smoking among Asians and Asian Americans. Meanwhile, this deleterious effect of religious discrimination does not vary by important sociodemographic variables, such as ethnicity, religious identity, gender, and acculturation. Surprisingly, once controlling for religious discrimination, racial discrimination was no longer associated with smoking. Therefore, when it comes to smoking, it may be possible that religion is a more hazardous source of minority stress than race for Asians and Asian Americans.
