With consumption upgrading,the tomato consumption market is showing a diversified trend,and consumers’demand for high-quality tomatoes is becoming increasingly prominent.To gain insights into the pattern of China’s tomato industry amidst evolving market demands,this study conducted interviews with representatives from large domestic agricultural product wholesale markets,tomato breeding experts,and enterprises,and provided an analysis of the current status and development of China’s tomato industry.Currently,China’s tomato cultivation area continues to expand,with advantageous production regions developing rapidly. The varieties of tomatoes and cultivation methods are becoming increasingly diverse,and the market share of domestically bred varieties is gradually increasing.Molecular breeding and gene editing technologies are driving improvements in tomato breeding efficiency and the creation of disease-resistant germplasm.Moreover,the operation model of the entire tomato industry chain is emerging,and there is an urgent need to establish a tomato quality standard system to promote premium pricing for high-quality products,thereby meeting the market’s diversified and high-quality demands.
Abstract:Gene editing technology has become an important means of crop molecular breeding. Currently,
gene edited vegetables have been launched and sold abroad.With the clarity of supervision policy on gene
editing breeding and the encouragement measures,the development and cultivation of new varieties of gene
edited vegetables are on the rise.This article analyzes the application trends,regional distribution,applicant and technology field distribution of gene edited vegetable breeding related patents through keyword and IPC classification number searches in the patent database.It provides a preliminary exploration of the basic overview of global gene edited vegetable breeding research and development,clarifies the distribution of technological strength of innovative entities,and provides guidance for domestic innovative entities based on the analysis of the gene edited vegetable varieties which have been sold abroad.Finally we make a summary and prospect based on patent information analysis.
Abstract:Through discussions and field research with the local agricultural industry authorities,leading
enterprises and large growers,the basic situation of vegetable planting,cultivation of market players,
processing and sales,product development and brand building,and employment promotion in the three
cities of Northwest Yunnan were comprehensively understood. Summarize and analyze the current situation,
characteristics,advantages and problems of vegetable industry development in 3 cities. The developmentsuggestions were put forward to optimize the regional layout of vegetable planting,improve the technical system of vegetable standardization industry in cold summer areas,focus on developing the intensive processing of vegetables,implement the strategy of vegetable brand,strengthen the cultivation of new business entities,steadily promote the integrated development of the whole industrial chain of vegetables,enhance the support capacity of industrial science and technology,carry out the renovation project of old facilities,and rationally optimize the farming system.
Abstract:To explore the variations in the expression patterns of genes associated with parthenocarpy in
eggplant,transcriptome sequencing technology was used to analyze the parthenocarpic inbred line‘T-2’and the non-parthenocarpic inbred line‘T-11’.The findings revealed 708 significantly differentially expressed genes between the parthenocarpic and non-parthenocarpic inbred lines,encompassing 439 up-regulated genes and 269 down-regulated genes.GO enrichment analysis indicated that among the three major functional categories(biological process,cellular component,and molecular function),the up-regulated genes were primarily enriched in 8 pathways.Further KEGG enrichment analysis identified 6 365 genes,with 141 of them being significantly differentially expressed,and 84 gene pathways were annotated.qRT-PCR analysis demonstrated that in the inbred line‘T-2’,the expression peaks of 16 genes mostly occurred at 3 days post-flowering,whereas thepeak times in the inbred line‘T-11’were more dispersed.Comprehensive analysis suggested that these genes may play a crucial role in the hormone signal transduction process during eggplant parthenocarpy.
Abstract:Pugionium dolabratum is a kind of rare and endangered Cruciferous germplasm,exhibiting
multi-stress resistance such as drought and saline-alkali tolerance,with significant ecological and agricultural value.Imaging flow cytometry can distinguish nuclear signals from non-nucleus interference signals,resulting in higher accuracy.To investigate the genome sizes and their variation among different populations of P. dolabratum,this study employed imaging flow cytometry to analyze the nuclei from five P. dolabratum populations.The estimated genome sizes were 416-494 Mb,with a variation of 18.8%,indicating significant genetic differences among different populations.Four populations were surveyed using high-throughput sequencing,and the predicted genome sizes were 442-484 Mb.The results of the both methods were relatively similar(consistency 93%-97%,when heterozygosity < 2%),confirming the reliability of imaging flow cytometry.For the genome heterozygosity exceeds 2%,the difference between the two methods reached 16%,indicating that it is necessary to use imaging flow cytometry to evaluate genome size in plants with high heterozygosity.The results provide technical support and data basis for genome sequencing,germplasm
protection on P. dolabratum.
Abstract:Leaf spot is one of the main diseases of Hemerocallis citrine,there are many kinds of pathogens,but no fungicides have been registered to control the disease.In order to clarify the pathogen community structure of Hemerocallis citrine leaf spot disease in Shanxi Province and effectively control the harm caused by this disease,the pathogen community structure of Hemerocallis citrine leaf spot disease of samples collected from 4 ecological regions in Shanxi Province was analyzed,and the field control effect of 25 pesticides on Hemerocallis citrine leaf spot disease.The results showed that among the four leaf spot disease samples of Hemerocallis citrine in Shanxi Province,Fusarium tricinctum had the highest isolation frequency,reaching 47.79%,and it was the dominant pathogen community of the leaf spot disease in Shanxi Province .The isolation frequency of Alternaria tenuissima was 30.63%,that of Fusarium oxysporum was 8.29%,and that of Fusarium verticillioides was 5.91%.12 chemical fungicides were during 37.91% and 62.08%,and the best ones were fludimine and Carbendazim.The control effects of tebuconazole and difenoconazole were 53.03% and 56.40%,respectively.Among 3 kinds of bacillus fungicides,including Bacillus methylotrophic, Bacillus subtilis and Bacillus polymyxa,had the best control effect,and the control effect ranged from 49.78% to 55.95%.There were significant differences in control effects among different types of pesticides,and there were also some differences among the same type.The results provide data support for the selection of chemical and biological agents for the control of Hemerocallis citrine leaf spot disease.
Abstract:Using the male sterile plant‘ODDBY001’and the fertile plant‘ODDKY001’,collected from Cha’nong Village,Xiaoweizhai Town,Duyun City,Guizhou Province,as the test materials,the morphology,floral organ structural traits,and fertility differences between the sterile and fertile plants were analyzed.The results showed that‘ODDBY001’was male sterile belong the species Oenanthe dielsii de Boiss,with withered filaments,small anthers,no pollen grains,the style elongated and not visibly exposed;whereas the fertile plant‘ODDKY001’has elongated filaments,the anthers were plump containing a large number of pollen grains,and the style shorter.Genetic analysis indicated that a severe deletion occurred in the atp6 gene at the 5′end of the mitochondrial genome in both‘ODDBY001’and‘ODDKY001’,with fertility types of S(rr)and S(Rr),respectively.
