| 1 | Acquisition of deleterious mutations duringpotato polyploidization显示文摘Potatoes(Solanum tuberosum L.) represent an important tuber crop, worldwide. During its prolonged clonal propagation, numerous deleterious mutations have accumulated in the potato genome,leading to severe inbreeding depression; however,the shaping of this mutation burden during polyploidization and improvement is largely unknown.Here, we sequenced 20 diploid landraces of the Stenotomum group, eight tetraploid landraces, and 20 tetraploid modern cultivars, to analyze variations in their deleterious mutations. We show that deleterious mutations accumulated rapidly during the polyploidization of tetraploid potatoes. This study provides a foundation for future potato improvement. | Qun Lian Die Tang Zhiyan Bai Jianjian Qi Fei Lu Sanwen Huang Chunzhi Zhang | 2019 | Journal of Integrative Plant Biology2019，61，1： | 8 |
| 2 | Brain Emotional Oscillatory Activity for Anger Revealed by Event-Related Spectral Perturbation显示文摘In order to find out the special cognitive emotional information to reach good accuracy in the recognition of anger emotions, the brain emotional oscillatory activity induced by relaxation and anger affective pictures is investigated in the amplitude measurement. A visual evoked affective experiment is designed and carried out to collect the electroencephalogram(EEG)data labeled with anger and relaxation emotion states. Twenty-one healthy college students(female 9, male 12) are employed to stimulate emotion by different affective pictures. Event-Related Spectral Perturbation(ERSP) is used to discover the pronounced features of anger tendency prediction in the time-frequency domain. ERSP maps exhibit that there is a difference between the female and male group, which is statistically significant within the 150-250 ms and 350-450 ms time range of alpha band. The male group is more susceptible to anger than female group, while the female group is faster in emotional regulation than the male group.These feature values could be used to identify the tendency of angry emotion, which can provide certain reference basis for further research on the predict the tendency of aggressive behavior. | DU Ruoyu BIAN Yucai BAI Zhiyan ZHU Yingying | 2020 | Wuhan University Journal of Natural Sciences2020，25，2： | 1 |
