| 1 | Research Progress on Heat Stress of Rice at Flowering Stage显示文摘Global warming has caused frequent occurrence of heat stress at the flowering stage of single-season rice in the Yangtze River region of China, which results in declines of spikelet fertility and yield in rice. Rice flowering stage is the most sensitive period to high temperatures, and therefore, the key for heat stress happening is the flowering stage coinciding with high temperature, which causes spikelet fertility decreasing in heat-sensitive varieties, and is the major factor for heat injury differences among various rice planting regions. With the development of rice breeding, temperature indexes for heat stress has been converted from daily maximum temperature of 35 oC to 38 oC with the stress duration of more than 3 d. During the flowering stage, anther dehiscence inhibition and low pollen shedding onto the stigma are two main reasons for spikelet fertility reduction under high temperatures. At panicle initiation stage, high temperatures aggravate spikelet degeneration, and destroy floral organ development. Various types of rice varieties coexist in production, and indica-japonica hybrid rice demonstrates the highest heat resistance in general, followed by indica and japonica rice varieties. In production, avoiding high temperature is the main strategy of preventing heat stress, and planting suitable cultivars and adjustment of sowing date are the most effective measures. Irrigation is an effective real-time cultivation measure to decline the canopy temperature during the rice flowering stage. We suggested that further study should be focused on exploring heat injury differences among different rice variety types, and innovating rice-planting methods according to planting system changes in rice planting regions with extreme heat stress. Meanwhile, high temperature monitor and warning systems should be improved to achieve optimal heat stress management efficiencies. | WANG Yaliang WANG Lei ZHOU Jianxia HU Shengbo CHEN Huizhe XIANG Jing ZHANG Yikai ZENG Yongjun SHI Qinghua ZHU Defeng ZHANG Yuping | 2019 | Rice science2019，26，1： | 13 |
| 2 | Chimeric antigen receptor T (CAR-T) cells expanded with IL-7/IL-15 mediate superior antitumor effects显示文摘Dear Editor,Genetic engineering of T cells to express chimeric antigen receptors(CARs)is an efficient approach for clinical therapy of hematological malignancies(Kuwana et al.,1987;Eshhar et al.,1993;Barrett et al.,2014).The CARs endow T cells with the ability to recognize specific antigens and bind them in an MHC-independent mariner,thereby overcoming some of the mechanisms that mediate tumor immune escape.In addition,by providing co-stimulatory signals,CARs endow T cells with enhanced cytotoxicity and persistence compared with primary T cells.A typical CAR comprises a single-chain variable frag me nt(scFv)derived from a monoclonal an tibody(mAb)for an tige n recog nition and signaling domains for co?activation(Eshhar et al.,1993;Sadelain et al.,2013). | Jianxia Zhou Liyuan Jin Fuping Wang Yuan Zhang Bing Liu Tongbiao Zhao | 2019 | Protein & Cell2019，10，10： | 7 |
| 3 | The combination of chidamide with the CHOEP regimen in previously untreated patients with peripheral T-cell lymphoma: a prospective, multicenter, single arm, phase 1b/2 study显示文摘Objective:To assess the efficacy and safety of the novel histone deacetylase inhibitor,chidamide,in combination with cyclophosphamide,doxorubicin,vincristine,etoposide,and prednisone(Chi-CHOEP)for untreated peripheral T-cell lymphoma(PTCL).Methods:A prospective,multicenter,single arm,phase 1 b/2 study was conducted.A total of 128 patients with untreated PTCL(18–70 years of age)were enrolled between March 2016 and November 2019,and treated with up to 6 cycles with the Chi-CHOEP regimen.In the phase 1 b study,3 dose levels of chidamide were evaluated and the primary endpoint was determination of the maximumtolerated dose and recommended phase 2 dose(RP2 D).The primary endpoint of the phase 2 study was 2-year progression-free survival(PFS).Results:Fifteen patients were enrolled in the phase 1 b study and the RP2 D for chidamide was determined to be 20 mg,twice a week.A total of 113 patients were treated at the RP2 D in the phase 2 study,and the overall response rate was 60.2%,with a complete response rate of 40.7%.At a median follow-up of 36 months,the median PFS was 10.7 months,with 1-,2-,and 3-year PFS rates of 49.9%,38.0%,and 32.8%,respectively.The Chi-CHOEP regimen was well-tolerated,with grade 3/4 neutropenia occurring in approximately two-thirds of the patients.No unexpected adverse events(AEs)were reported and the observed AEs were manageable.Conclusions:This large cohort phase 1 b/2 study showed that Chi-CHOEP was well-tolerated with modest efficacy in previously untreated PTCL patients. | Wei Zhang Liping Su Lihong Liu Yuhuan Gao Quanshun Wang Hang Su Yuhuan Song Huilai Zhang Jing Shen Hongmei Jing Shuye Wang Xinan Cen Hui Liu Aichun Liu Zengjun Li Jianmin Luo Jianxia He Jingwen Wang O.A.O’Connor Daobin Zhou | 2021 | Cancer Biology & Medicine2021，18，3： | 4 |
| 4 | A histological and biomechanical study of bone stress and bone remodeling around immediately loaded implants显示文摘Immediate loading(IL)increases the risk of marginal bone loss.The present study investigated the biomechanical response of peri-implant bone in rabbits after IL,aiming at optimizing load management.Ninety-six implants were installed bilaterally into femurs of 48 rabbits.Test implants on the left side created the maximal initial stress of 6.9 and 13.4 MPa in peri-implant bone and unloaded implants on the contralateral side were controls.Bone morphology and bone-implant interface strength were measured with histological examination and push-out testing during a 12-week observation period.Additionally,the animal data were incorporated into finite element(FE)models to calculate the bone stress distribution at different levels of osseointegration.Results showed that the stress was concentrated in the bone margin and the bone stress gradually decreased as osseointegration proceeded.A stress of about 2.0 MPa in peri-implant bone had a positive effect on new bone formation,osseointegration and bone-implant interface strength.Bone loss was observed in some specimens with stress exceeding 4.0 MPa.Data indicate that IL significantly increases bone stress during the early postoperative period,but the load-bearing capacity of peri-implant bone increases rapidly with an increase of bone-implant contact.Favorable bone responses may be continually promoted when the stress in peri-implant bone is maintained at a definite level.Accordingly,the progressive loading mode is recommended for IL implants. | HAN JingYun HOU JianXia ZHOU Gang WANG Chao FAN YuBo | 2014 | Science China(Life Sciences)2014，57，6： | 2 |

| 7 | Genomes of 12 fig wasps provide insights into the adaptation of pollinators to fig syconia显示文摘Figs and fig pollinators are one of the few classic textbook examples of obligate pollination mutualism.The specific dependence of fig pollinators on the relatively safe living environment with sufficient food sources in the enclosed fig syconia implies that they are vulnerable to habitat changes.However,there is still no extensive genomic evidence to reveal the evolutionary footprint of this long-term mutually beneficial symbiosis in fig pollinators.In fig syconia,there are also non-pollinator species.The non-pollinator species differ in their evolutionary and life histories from pollinators.We conducted comparative analyses on 11 newly sequenced fig wasp genomes and one previously published genome.The pollinators colonized the figs approximately 66.9 million years ago,consistent with the origin of host figs.Compared with nonpollinators,many more genes in pollinators were subject to relaxed selection.Seven genes were absent in pollinators in response to environmental stress and immune activation.Pollinators had more streamlined gene repertoires in the innate immune system,chemosensory toolbox,and detoxification system.Our results provide genomic evidence for the differentiation between pollinators and nonpollinators.The data suggest that owing to the long-term adaptation to the fig,some genes related to functions no longer required are absent in pollinators. | Jinhua Xiao Xianqin Wei Yi Zhou Zhaozhe Xin Yunheng Miao Hongxia Hou Jiaxing Li Dan Zhao Jing Liu Rui Chen Liming Niu Guangchang Ma Wenquan Zhen Shunmin He Jianxia Wang Xunfan Wei Weihao Dou Zhuoxiao Sui Haikuan Zhang Shilai Xing Miao Shi Dawei Huang | 2021 | Journal of Genetics and Genomics2021，48，3： | 1 |
| 8 | Breeding dominant genic male sterility restorer line of Brassica napus L.显示文摘To facilate breeding process of Brassica napus,a microspore culture and molecular marker-assisted screening combined system were proposed in this research.At early flowering stage,F1 offspring of hybridized combination HY15 A×HF06 was used as donor for microspore culture to analyze effects of colchicine concentration on embryogenic and diploid rates of microspore.Treatment with 50 mg/L colchicine resulted in embryogenic rate of3.56 embryos/bud,which was substantially higher than control(0.78 embryos/bud).A total of 1,387 embryos and 862 single plants were obtained after induction culture.Ploidy detection was performed for the regenerated plants by flow cytometry.Diploid rates of microspores treated with 50 mg/L and 70 mg/L colchicine were 17.2%and 21.0%respectively,which was significantly higher than control(10.5%).Totally 108 single plants that doubled successfully were randomly selected and screened using molecular marker BE10.Approximately 54 of108 plants generated a 305 bp amplification product,whereas the other 54 plants showed a 398 bp band,thereby satisfying 1:1 separation ratio(x0.052=0.0093).These coincided with field identification results.Findings of this study indicated that homozygous breeding material could be obtained by microspore culture in a short time,thereby remarkably accelerate breeding. | Junying Zhang Jianxia Jiang Liyong Yang Meiyan Jiang Yanli Li Weirong Wang Chaocai Sun Jifeng Zhu Xirong Zhou | 2020 | Oil Crop Science2020，5，2： | 0 |
