| 1 | Pan-plastome approach empowers the assessment of genetic variation in cultivated Capsicum species显示文摘Pepper species(Capsicum spp.)are widely used as food,spice,decoration,and medicine.Despite the recent old-world culinary impact,more than 50 commercially recognized pod types have been recorded worldwide from three taxonomic complexes(A,B,and P).The current study aimed to apply a pan-plastome approach to resolve the plastomic boundaries among those complexes and identify effective loci for the taxonomical resolution and molecular identification of the studied species/varieties.High-resolution pan-plastomes of five species and two varieties were assembled and compared from 321 accessions.Phyloplastomic and network analyses clarified the taxonomic position of the studied species/varieties and revealed a pronounced number of accessions to be the rare and endemic species,C.galapagoense,that were mistakenly labeled as C.annuum var.glabriusculum among others.Similarly,some NCBIdeposited plastomes were clustered differently from their labels.The rpl23-trnI intergenic spacer contained a 44 bp tandem repeat that,in addition to other InDels,was capable of discriminating the investigated Capsicum species/varieties.The rps16-trnQ/rbcL-accD/ycf3-trnS gene set was determined to be sufficiently polymorphic to retrieve the complete phyloplastomic signal among the studied Capsicum spp.The pan-plastome approach was shown to be useful in resolving the taxonomical complexes,settling the incomplete lineage sorting conflict and developing a molecular marker set for Capsicum spp.identification. | Mahmoud Magdy Lijun Ou Huiyang Yu Rong Chen Yuhong Zhou Heba Hassan Bihong Feng Nathan Taitano Esther van der Knaap Xuexiao Zou Feng Li Bo Ouyang | 2019 | Horticulture Research2019，6，1： | 1 |
| 2 | Problems and Countermeasures of Fruit and Vegetable Logistics Distribution Development in Guangxi Zhuang Autonomous Region显示文摘The logistics transportation and distribution of fruits and vegetables has become one of the important links for people to obtain food,and it is also an important direction and emerging challenge in the logistics industry.As the social economy and transportation develop,the consumption ability of residents has been improved,and the high demand for fruits and vegetables has promoted the transportation of fruits and vegetables to meet the development conditions of the future fruit and vegetable industry.The study of fruit and vegetable logistics distribution can improve the efficiency of fruit and vegetable distribution,improve the construction of fruit and vegetable distribution system,and also meet the needs of people for different kinds of fruits and vegetables.Taking Guangxi fruit and vegetable distribution as an example,through empirical investigation,this paper studies the existing problems in the development of logistics distribution in the fruit and vegetable distribution industry,and puts forward corresponding measures and countermeasures according to the problems,so as to innovate the fruit and vegetable distribution mode in Guangxi Zhuang Autonomous Region. | Xi XU Bihong FENG | 2023 | Asian Agricultural Research2023，15，10： | 0 |
| 3 | CRISPR/Cas9-mediated gene-editing technology in fruit quality improvement显示文摘Fruits are an essential part of a healthy,balanced diet and it is particularly important for fibre,essential vitamins,and trace elements.Improvement in the quality of fruit and elongation of shelf life are crucial goals for researchers.However,traditional techniques have some drawbacks,such as long period,low efficiency,and difficulty in the modification of target genes,which limit the progress of the study.Recently,the clustered regularly interspaced short palindromic repeats(CRISPR)/Cas9 technique was developed and has become the most popular gene-editing technology with high efficiency,simplicity,and low cost.CRISPR/Cas9 technique is widely accepted to analyse gene function and complete genetic modification.This review introduces the latest progress of CRISPR/Cas9 technology in fruit quality improvement.For example,CRISPR/Cas9-mediated targeted mutagenesis of RIPENING INHIBITOR gene(RIN),Lycopene desaturase(PDS),Pectate lyases(PL),SlMYB12,and CLAVATA3(CLV3)can affect fruit ripening,fruit bioactive compounds,fruit texture,fruit colouration,and fruit size.CRISPR/Cas9-mediated mutagenesis has become an efficient method to modify target genes and improve fruit quality. | Xin Xu Yujin Yuan Bihong Feng Wei Deng | 2020 | Food Quality and Safety2020，4，4： | 0 |
