(1) Background: Cytoplasmic male sterility (CMS) is important for exploiting heterosis. Soybean (Glycine max L.) has a low outcrossing rate that is detrimental for breeding sterile lines and producing hybrid seeds. Therefore, the molecular mechanism

Abstract The newly confirmed pentaquark state $$P_c(4312)$$ Pc(4312) has been treated as a weakly bound $$(\Sigma _c\bar{D})$$ (ΣcD¯) state by a well-established chiral constituent quark model and by a dynamical calculation on quark degrees of free
