以叶片全缘(entire)莴苣PI491070和叶裂(lobed)莴苣PI536760为亲本构建F_2代分离群体,F_2代性状分离调查结果显示叶裂性状为单基因显性性状。利用BSR-seq方法对莴苣叶裂性状进行快速遗传定位,将控制叶裂性状的基因定位在3号染色体的60~140 Mb之间。通过1 159株F_2群体的隐性单株进行分析最终将目的基因定位在116.24~118.15 Mb之间,物理距离大约为1.91 Mb。该区域包括24个候选基因,其中基因LG3316063编码锌指蛋白,在两亲本中有1个碱基的差异并导致了氨基酸的改变。从莴苣资源库中随机挑选5种叶裂植株检测该基因差异SNP位点都为G,7种无叶裂植株该基因SNP都为T,推测该基因可能是控制叶裂形成的候选基因。

The feasibility of this decision-making module is verified through circuit simulations. Taking a multi-layer perceptron as an example, the module significantly improves the accuracy of the perceptron in the handwritten digit recognition task. Furthermore, the spintronic decision-making module offers advantages over the conventional pooling methods, such as adaptive decision time, high performance and the absence of analog-to-digital conversion. The decision-making module is flexible to be integrated into artificial neural networks and provides a general yet effective solution to enhance performance against device noise.

In the pathogenesis of major depressive disorder, chronic stress-related neuroinflammation hinders favorable prognosis and antidepressant response. Mitochondrial DNA may be an inflammatory trigger, after its release from stress-induced dysfunctional central nervous system mitochondria into peripheral circulation. This evidence supports the potential use of peripheral mitochondrial DNA as a neuroinflammatory biomarker for the diagnosis and treatment of major depressive disorder. Herein, we critically review the neuroinflammation theory in major depressive disorder, providing compelling evidence that mitochondrial DNA release acts as a critical biological substrate, and that it constitutes the neuroinflammatory disease pathway. After its release, mitochondrial DNA can be carried in the exosomes and transported to extracellular spaces in the central nervous system and peripheral circulation. Detectable exosomes render encaged mitochondrial DNA relatively stable. This mitochondrial DNA in peripheral circulation can thus be directly detected in clinical practice. These characteristics illustrate the potential for mitochondrial DNA to serve as an innovative clinical biomarker and molecular treatment target for major depressive disorder. This review also highlights the future potential value of clinical applications combining mitochondrial DNA with a panel of other biomarkers, to improve diagnostic precision in major depressive disorder.
