| 1 | Differential SW16.1 allelic effects and genetic backgrounds contributed to increased seed weight after soybean domestication显示文摘Although seed weight has increased following domestication from wild soybean(Glycine soja) to cultivated soybean(Glycine max), the genetic basis underlying this change is unclear. Using mapping populations derived from chromosome segment substitution lines of wild soybean, we identified SW16.1 as the causative gene underlying a major quantitative trait locus controlling seed weight.SW16.1 encodes a nucleus-localized LIM domaincontaining protein. Importantly, the GsSW16.1 allele from wild soybean accession N24852 had a negative effect on seed weight, whereas the GmSW16.1 allele from cultivar NN1138-2 had a positive effect. Gene expression network analysis,reverse-transcription quantitative polymerase chain reaction, and promoter-luciferase reporter transient expression assays suggested that SW16.1 regulates the transcription of MT4, a positive regulator of seed weight. The natural variations in SW16.1 and other known seed weight genes were analyzed in soybean germplasm. The SW16.1 polymorphism was associated with seed weight in 247 soybean accessions, showing much higher frequency of positive-effect alleles in cultivated soybean than in wild soybean. Interestingly,gene allele matrix analysis of the known seed weight genes revealed that G. max has lost 38.5%of the G. soja alleles and that most of the lost alleles had negative effects on seed weight. Our results suggest that eliminating negative alleles from G. soja led to a higher frequency of positive alleles and changed genetic backgrounds in G. max,which contributed to larger seeds in cultivated soybean after domestication from wild soybean.Our findings provide new insights regarding soybean domestication and should assist current soybean breeding programs. | Xianlian Chen Cheng Liu Pengfei Guo Xiaoshuai Hao Yongpeng Pan Kai Zhang Wusheng Liu Lizhi Zhao Wei Luo Jianbo He Yanzhu Su Ting Jin Fenfen Jiang Si Wang Fangdong Liu Rongzhou Xie Changgen Zhen Wei Han Guangnan Xing Wubin Wang Shancen Zhao Yan Li Junyi Gai | 2023 | Journal of Integrative Plant Biology2023，65，7： | 1 |

| 3 | 低温下高能重离子辐照低活化铁素体/马氏体钢CLF-1的微硬度变化行为研究显示文摘In the present work,irradiation hardening of a reduced activation ferritic/martensitic steel CLF-1 candidate to fusion reactor blankets was studied.Specimens were irradiated with high-energy N and Fe ions at about-50℃.Energy of the incident ions was dispersed to successively decreasing 10 grades by using an energy degrader,thereby generating an atomic displacement damage plateau in the specimens from the surface to a depth of 25m,which is sufficiently broad for the Vickers hardness test.Three damage levels of 0.05,0.1 and 0.2 dpa were approached.Depth distribution of atomic displacement damage(in dpa)was estimated by SRIM 2013 code(using Kinchin-Pease model,with a displacement threshold energy Ed=40 eV[1]). | Ding Zhaonan Zhang Chonghong Yang Yito Chen Yuguang Zhang Xianlong Song Yin Ma Tongda Xu Yuping Luo Guangnan | 2018 | IMP & HIRFL Annual Report2018，，1： | 0 |
| 4 | 3-31 Study on Hardening Caused by He Ion Implantation in Two Kinds of Reduced-activation Ferritic/Martensitic Steels Made in China显示文摘Reduced activation ferritic/martensitic steels (RAFM) are important candidate materials for future nuclear fusion reactors because of their high thermal conductivity, low thermal expansion rate and high resistance to void swelling. The influence of the accumulation of high concentration of helium via the(n, a)nuclear reaction on microstructures and macro-properties of the steels is an important issue limiting the service lifetime of the materials. | Fan Jiaqi Yang Yitao Ding Zhaonan Li Caisheng Zhang Chonghong Xu Yuping Luo Guangnan | 2015 | IMP & HIRFL Annual Report2015，，1： | 0 |
| 5 | 3-32 Irradiation Hardening of A Domestic Reduced Activation Ferritic/martensitic Steel under High Energy Heavy-ion Bombardment显示文摘As a prime candidate for the structure components of fusion reactors, irradiation resistance of the reduced activation ferritic/martensitic steel (RAFM) has obtained intensive concern. In the present work, irradiation response of a domestic 8%-Cr RAFM was tested at the terminal SFC-T1 of HIRFL. | Ding Zhaonan Yang Yitao Song Yin Zhang Liqing Gou Jie Zhang Chonghong Xu Yuping Luo Guangnan | 2015 | IMP & HIRFL Annual Report2015，，1： | 0 |
