Team emotional intelligence is expected to have a significant impact on intrateam conflict and team effectiveness. However, to date, there has been a dearth of empirical evidence of this link. Taking a comprehensive approach, our study contributes to the literature on intrateam conflict and team emotional intelligence. Data collected from 79 teams in South Korean companies reveal that team emotional intelligence is negatively related to team process (i.e., task conflict and relationship conflict) and positively related to team effectiveness (i.e., team performance, innovation, and cohesion). In addition, team emotional intelligence has a moderating effect on decoupling task conflict and relationship conflict. Our findings also indicate that team emotional intelligence decreases the negative effects of task conflict on team effectiveness, and of relationship conflict on team cohesion. We conclude this study with a discussion of limitations and implications for future research.

The physiological function of Arabidopsis thaliana universal stress protein (AtUSP) in plant has remained unclear. Thus, we report here the functional role of the Arabidopsis universal stress protein, AtUSP (At3g53990). To determine how AtUSP affects physiological responses towards cold stress, AtUSP overexpression (AtUSP OE) and T-DNA insertion knock-out (atusp, SALK_146059) mutant lines were used. The results indicated that AtUSP OE enhanced plant tolerance to cold stress, whereas atusp did not. AtUSP is localized in the nucleus and cytoplasm, and cold stress significantly affects RNA metabolism such as by misfolding and secondary structure changes of RNA. Therefore, we investigated the relationship of AtUSP with RNA metabolism. We found that AtUSP can bind nucleic acids, including single- and double-stranded DNA and luciferase mRNA. AtUSP also displayed strong nucleic acid-melting activity. We expressed AtUSP in RL211 Escherichia coli, which contains a hairpin-loop RNA structure upstream of chloramphenicol acetyltransferase (CAT), and observed that AtUSP exhibited anti-termination activity that enabled CAT gene expression. AtUSP expression in the cold-sensitive Escherichia coli (E. coli) mutant BX04 complemented the cold sensitivity of the mutant cells. As these properties are typical characteristics of RNA chaperones, we conclude that AtUSP functions as a RNA chaperone under cold-shock conditions. Thus, the enhanced tolerance of AtUSP OE lines to cold stress is mediated by the RNA chaperone function of AtUSP.
