to investigate the nature of the Ψ（3770） resonance and to measure the cross section for e^＋e^-→DD, a cross-section scan data sample, distributed among 41 center-of-mass energy points from 3.73 to 3.89 GeV, was taken with.t.e BESIII detector operated at the BEPCII collider in the year 2010. By analyzing the large angle Bhabha scattering events, we measure the integrated luminosity of the data sample at each center-of-mass energy point. the total integrated luminosity of the data sample is 76.16±0.04±0.61 pb^-1, where the first uncertainty is statistical and the second systematic.

Cold stress is an important factor th.t.limits apple production. In this study, we examined the tissue-cultured plantlets of apple rootstocks ‘m9t337' and ‘60-160', which are resistant and sensitive to cold stress, respectively. the enriched pathways of differentially ex.r.ssed genes(DEGs) and physiological changes in ‘m9t337' and ‘60-160' plantlets were clearly different after cold stress(1°C) treatment for 48 h, suggesting th.t.they have differential responses to cold stress. the differential ex.r.ssion of WrKY transcription factors in the two plantlets showed th.t.mdWrKY40is and mdWrKY48 are potential regulators of cold tolerance. When we overex.r.ssed mdWrKY40is and mdWrKY48in apple calli, the overex.r.ssion of mdWrKY48 had no significant effect on the callus, while mdWrKY40is overex.r.ssion promoted anthocyanin accumulation, increased callus cold tolerance, and promoted the ex.r.ssion of anthocyanin structural gene mdDfr and cold-signaling core gene mdCBf2. Yeast one-hybrid screening and electrophoretic mobility shift assays showed th.t.mdWrKY40is could only bind to the mdDfr promoter. Yeast twohybrid screening and bimolecular fluorescence complementation showed th.t.mdWrKY40is interacts with.t.e CBf2inhibitor mdmYB15L through.t.e leucine zipper(LZ). When the LZ of mdWrmY40is was knocked out, mdWrKY40is overex.r.ssion in the callus did not affect mdCBf2 ex.r.ssion or callus cold tolerance, indicating th.t.mdWrKY40is acts in the cold signaling pathway by interacting with mdmYB15L. In summary, mdWrKY40is can directly bind to the mdDfr promoter in order to promote anthocyanin accumulation, and it can also interact with mdmYB15L to interfere with its inhibitory effect on mdCBf2, indirectly promoting mdCBf2 ex.r.ssion, and thereby improving cold *** results provide a new perspective for the cold-resistance mechanism of apple rootstocks and a molecular basis for the screening of cold-resistant rootstocks.

China experienced worsening ground-level ozone(O_(2)) pollution from 2013 to 2019. In this study, meteorological parameters, including surface temperature(t_(2)), solar radiation(SW), and wind speed(WS), were classified into two aspects,(1) Ph.t.chemical reaction Condition(PrC = t_(2)× SW) and(2) Physical Dispersion Capacity(PDC = WS). In this way, a meteorology Synth.t.c Index(mSI = PrC/PDC) was developed for the quantification of meteorology-induced ground-level O_(2)pollution. the positive linear relationship between the 90 th percentile of mDA8(maximum daily 8-h average) O_(2)concentration and mSI determined th.t.the contribution of meteorological changes to ground-level O-3 varied on a latitudinal gradient, decreasing from ~40% in southern China to 10%–20% in northern China. favorable ph.t.chemical reaction conditions were more important for ground-level O_(2)pollution. this study proposes a universally applicable index for fast diagnosis of meteorological roles in ground-level O_(2)variability, which enables the assessment of the observed effects of precursor emissions reductions th.t.can be used for designing future control policies.
