Pod shattering is an important domesticated trait which can cause great economic loss of crop yield in cultivated *** this study,we utilized two recombinant inbred line populations(RILs,CY,Huachun 2×Wayao;GB,Guizao 1×B13)to identify quantitative trait loci(QTLs)associated with pod shattering in soybean across multiple environments.A total of 14 QTLs for pod shattering were identified in the two RIL populations,which had LOD scores ranging from 2.64 to 44.33 with phenotypic variance explanation(PVE)ranging from 1.33 to 50.85%.One QTL qPS16-1,located on chromosome 16,included a well-known functional gene Pod dehiscence 1(Pdh1)that was reported *** new putative QTLs were validated in two RIL populations,and their LOD scores were between 2.55 and 4.24,explaining 1.33 to 2.60%of the phenotypic *** which four novel QTLs(qPS01-1,qPS03-2,qPS05-1,and qPS07-1)could be detected in two environments where nine genes had specific changes in gene *** the nine genes may have significant effects on pod shattering of soybean,their detailed functions still need to be further explored in the *** results of this study will facilitate a better understanding of the genetic basis of the pod shattering-resistant trait and benefit soybean molecular breeding for improving pod shattering resistance.

Self-assembled carbon monoxide nanoprodrug for chemiexcitationtriggered synergistic chemotherapy against breast cancer

Science China Chemistry 2025年

作者： Shunfei Cui Yiyao Pan Chenzhe ma bin qi qingqiang Min Ming Li Huabing Chen Hengte Ke Xingyue Ji Jiangsu Province Engineering Research Center of Precision Diagnostics and Therapeutics Development College of Pharmaceutical ScienceSoochow University

Carbon monoxide（CO） has recently been well-established as a promising therapeutic modality against cancer. The development of transition-metal-free and tumor-targeted delivery platforms for CO is highly demanded but remains very sporadic. Herein, we developed a polyprodrug system for the co-delivery of CO and a chemotherapeutic agent combretastin A-4（CA-4） to the tumor site based on a chemiexcitation mechanism. Such a poly-prodrug successfully achieved the co-activation of CO and CA-4 in response to H2O2at the tumor site both in vitro and in vivo. Importantly, a synergist effect between CO and CA-4 was observed in suppressing tumor growth in a mouse tumor model. It is anticipated that such a poly-prodrug system could be potentially adapted for the co-delivery of CO and another drug payload for combinational therapy for other indications.
