We used a 30-day daily diary assessment method to examine the within-person associations between social rejection, emotional experiences, and emotion regulation strategies in a sample of 34 college students. Taking emotional experience as the dependent variable, we explored and analyzed cumulative and hysteresis effects using a random regression coefficient model. The results showed that situations of social rejection tended to induce negative emotional experiences, for which college students mostly adopted attention transfer strategies. In contrast, positive emotional experience increased in situations of social acceptance, and college students mostly adopted cognitive reappraisal strategies in this setting. Further, cognitive reappraisal strategies had time accumulation and overlapping effects on individual positive emotional experiences, and attention transfer strategies had a lag effect on individual emotional experiences. These findings advance understanding of the negative affect–emotion regulation association among individuals exposed to social rejection. [ABSTRACT FROM AUTHOR]

Peucedanum franchetii is a famous folk medicinal plant in China. However, the taxonomy of the P. franchetii has not been sufficiently resolved. Due to similar morphological features between P. franchetii and Ligusticopsis members, the World Flora Online (WFO) Plant List suggested that this species transformed into the genus Ligusticopsis and merged with Ligusticopsis likiangensis. However, both species are obviously diverse in leaf shape, bracts, and bracteoles. To check the taxonomic position of P. franchetii, we newly sequenced and assembled the plastome of P. franchetii and compared it with nine other plastomes of the genus Ligusticopsis. Ten plastomes were highly conserved and similar in gene order, codon bias, RNA editing sites, IR borders, and SSRs. Nevertheless, 10 mutation hotspot regions (infA, rps8, matK, ndhF, rps15, psbA-trnH, rps2-rpoC2, psbA-trnK, ycf2-trnL, and ccsA-ndhD) were still detected. In addition, both phylogenetic analyses based on plastome data and ITS sequences robustly supported that P. franchetii was not clustered with members of Peucedanum but nested in Ligusticopsis. P. franchetii was sister to L. likiangensis in the ITS topology but clustered with L. capillacea in the plastome tree. These findings implied that P. franchetii should be transferred to genus Ligusticopsis and not merged with L. likiangensis, but as an independent species, which was further verified by morphological evidences. Therefore, transferring P. franchetii under the genus Ligusticopsis as an independent species was reasonable, and a new combination was presented. [ABSTRACT FROM AUTHOR]
