    The innate immune system of plants plays an important role in disease defense．Under pathogen attack，plant innate immune system can perceive injury via recognition pathogen-derived elicitors and endogenous danger signals molecules（DAMPs）and activate various defense responses．This thereby blocks or reduces the invasion of pathogen．Recently，some studies found that plant extracellular self-DNA（esDNA）fragments as a DAMP induces plant growth inhibition and immune response．In this paper，the production，functional characteristics，signaling pathways，potential receptors，and applications of esDNA are systematically summarized，which provides good reference for the further basic study and agricultural application of the signal molecule．

    FLOWERING LOCUS C（FLC）encodes MADS-box family protein and plays a key role in the vernalization pathway of Arabidopsis．To explore the role of BoFLCs in the vernalization pathway of cabbage，we knocked out BoFLCs in cabbage inbred line‘GL’by CRISPR/Cas9．All the knock-out lines had significantly earlier flowering time，providing insight into the function of BoFLCs gene．The BC1-2P2 and BC2F1 segregating populations were constructed using late-flowering cabbage inbred line‘20-2221’（P1，BoFLCs-w）and mid-early-flowering cabbage inbred line‘20-2229’（P2，BoFLCs-z）．Sequence analysis showed that BoFLC1，BoFLC3 and BoFLC5 had sequence differences between parents，and specific molecular markers were developed based on these sequence differences．The BC2F1 population was screened by the BoFLCs specific molecular markers．One plant containing BoFLC1-w/w and BoFLC5-w/w homozygous haplotype，and BoFLC3-w/z heterozygous haplotype（BC2F1-29）was obtained．The bolting time and flowering time of BC2F1-29 were 8.00 and 13.00 days later than those of backcross parent‘20-2229’，respectively．Four plants containing BoFLC1-w/w and BoFLC3-w/w homozygous haplotype，and BoFLC5-w/z heterozygous haplotype（BC2F1-55，BC2F1-119，BC2F1-121，BC2F1-163）were obtained．The average bolting time and flowering time of these four plants were 9.75 and 13.50 days later than those of‘20-2229’，respectively．In addition，three plants containing BoFLC1-w/w，BoFLC3-w/w and BoFLC5-w/w homozygous haplotype（BC2F1-82，BC2F1-106，BC2F1-192）were obtained．The average bolting time and flowering time of these three plants were 11.33 and 15.67 days later than those of‘20-2229’，respectively．In this study，BoFLCs specific molecular markers were developed and the excellent BoFLCs genotypes were efficiently pyramided and the bolting properties of parent‘20-2229’was improved．

    In order to reveal the composition difference of the wax powder metabolites on the surface of the broccoli inflorescence，taking the wax powder deficient mutant and the wild type of broccoli as test materials，based on the non-targeted metabolomics of gas chromatography tandem time-of-flight mass spectrometry（GC-TOF-MS），the main metabolic pathways and their products of the broccoli wax powder deficient mutant and the wild type were deeply analyzed，and the significantly different metabolites were screened by using univariate and multivariate variable statistical analysis and database annotation．The results showed that a total of 24 significantly different metabolites were detected in the wax powder of broccoli buds，including 14 kinds of amino acids，4 kinds of organic acids，1 kind of fatty acid，1 kind of amine，1 kind of sugar，and 3 kinds of other secondary metabolites．Among them，there were 18 kinds of down-regulated，including 13 kinds of amino acids．Through comprehensive enrichment analysis and topological analysis，11 important metabolic pathways with prominent significance were obtained，among which the most significantly different metabolic pathway was the biosynthesis of amino acids，followed by the biosynthesis of secondary metabolites；and the most important one was tryptophan metabolism．Therefore，it is speculated that the lack of broccoli wax powder can regulate the content such as amino acids and organic acids and other secondary metabolites in the broccoli buds by regulating the pathways such as tryptophan metabolism，the biosynthesis of secondary metabolites，and the biosynthesis of amino acids，then regulate the growth of the inflorescence，the nutritional quality，and the cold resistance．
