However, the genetic diversity responsible for its extensive phenotypic variations remains largely unexplored. Here, we assembled and annotated the genomes of the maternal (PsbM) and paternal (PsbF) lines of the hybrid ‘Yuluxiang’ pear and constructed the pear pangenome of 1.15 Gb by combining these two genomes with five previously published pear genomes representing cultivated and wild germplasm. Using the constructed pangenome, we identified 21 224 gene PAVs (Presence-absence variation) and 1 158 812 SNPs (Single Nucleotide Polymorphism) in the non-reference genome that were absent in the PsbM reference genome. Compared with SNP markers, PAV-based analysis provides additional insights into the pear population structure. In addition, some genes associated with pear fruit quality traits have differential occurrence frequencies and differential gene expression between Asian and European populations. Moreover, our analysis of the pear pangenome revealed a mutated SNP and an insertion in the promoter region of the gene potentially enhance sepal shedding in ‘Xuehuali’ which is vital for pear quality. may play a role in the IAA pathway, contributing to a distinct low-auxin phenotype observed in plants by heterologously overexpressing this gene. This research helps capture the genetic diversity of pear populations and provides genomic resources for accelerating breeding.","PeriodicalId":13178,"journal":{"name":"Horticultural Plant Journal","volume":null,"pages":null},"PeriodicalIF":5.7,"publicationDate":"2024-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142025157","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Almond kernel is consumed fresh or employed in the food industry. Hundreds of almond cultivars were selected throughout the long history of cultivation; in this context, an efficient method for varietal identification is essential to ensure cultivar traceability along the chain. This study surveyed the widely employed commercial kits and protocols for DNA extraction from several almond matrices including leaves, kernels (fresh and roasted) and several processed products. Commercial kits (though with minor modification) outperformed the other extraction methods for the isolation of DNA suitable for molecular analysis from all the tested matrices. In parallel, a germplasm collection composed of 140 accessions (123 Sicilian genotypes complemented with widely known national and international cultivars) was genotyped with the Axiom™ 60K almond SNP Array enabling the detection of 6 374 unique SNPs that can be readily used for varietal traceability. A subset of unique SNPs was further validated employing a high-resolution melting (HRM) assay on a discovery panel encompassing ten of the most widely cultivated accessions. The DNA extracted from leaves and kernels of five cultivars was genotyped with eight SSRs allowing the identification of the maternal origin of each kernel. The paper integrates the survey of the widely employed protocols for DNA extraction with the high-throughput genotyping of 140 almond accessions. In this context, unique SNPs validated and optimized for an HRM assay and the availability of SSR markers demonstrated their efficacy in traceability analysis along the chain.","PeriodicalId":13178,"journal":{"name":"Horticultural Plant Journal","volume":null,"pages":null},"PeriodicalIF":5.7,"publicationDate":"2024-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141904801","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, little is known about the influence of DNA methylation on secondary metabolism during leaf development in the tea plant (). In this study, we combined the methylome, transcriptome, and metabolome to investigate the dynamic changes in DNA methylation and its potential regulatory roles in secondary metabolite biosynthesis. In this study, the level of genomic DNA methylation increased as leaf development progressed from tender to old leaf. It additionally exhibited a similar distribution across the genomic background at the two distinct developmental stages studied. Notably, integrated analysis of transcriptomic and methylomic data showed that DNA hypermethylation primarily occurred in genes of the phenylpropanoid, flavonoid, and terpenoid biosynthesis pathways. The effect of methylation on transcription of these secondary metabolite biosynthesis genes was dependent on the location of methylation (i.e., in the promoter, gene or intergenic regions) and the sequence context (i.e., CpG, CHG, or CHH). Changes in the content of catechins and terpenoids were consistent with the changes in gene transcription and the methylation state of structural genes, such as (), (), and ().

We performed RNA interference and found that -suppressed transformants exhibited extremely low CO assimilation capacity, their photosystem I (PSI) and PSII were severely photoinhibited and chloroplasts were obviously damaged. The -suppressed plants almost completely inhibited CEF and Y(ND), and PSII photoinhibition may be directly related to the inability to produce sufficient proton motive force to induce NPQ. The transgenic plants overexpressing and driven by 35S promoter capable alleviate photoinhibition of plants under low night temperature. The transcriptomic and proteomic analyses suggested that the nuclear gene transcription and turnover of chloroplast proteins, including the plastoglobule-related proteins, were closely related to SlPGR5/SlPGRL1 pathway dependent CEF. The bridge relationship between CEF and chloroplast quality maintenance was a novel report to our knowledge.

In this study, the impacts of exogenous melatonin (MEL) on chlorophyll content and fluorescence, as well as ultrastructure and membrane lipid metabolism of chloroplasts in broccoli were investigated during postharvest. The results showed that MEL treatment (200 μmol L) maintained the chlorophyll content, chloroplast autofluorescence and integral structure, and reduced the level ofserotonin in the chloroplasts in broccoli. Also, MEL treatment inhibited the membrane lipid peroxidation of chloroplasts, as indicated by low levels of superoxide anion (O), hydrogen peroxide (HO) and malondialdehyde (MDA), and high levels of endogenous MEL. In addition, the stability and fluidity of chloroplast membranes were also better maintained in the treated broccoli via increasing the contents of phosphatidylglyceroland (PG), monogalactosyldiglyceride (MGDG), digalactosyldiglyceride (DGDG) and unsaturated fatty acids as well as decreasing saturated fatty acid content and the activities of lipoxygenase (LOX) and lipase (LPS). Thus, the application of MEL facilitated the maintenance of chloroplast integrity, thus contributing to yellowing postponement and the extension of the storage life of broccoli.","PeriodicalId":13178,"journal":{"name":"Horticultural Plant Journal","volume":null,"pages":null},"PeriodicalIF":5.7,"publicationDate":"2024-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141768945","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite its versatility, the occurrence of flowering in Moso bamboo poses a threat to bamboo forests, resulting in substantial losses. The underlying cause of bamboo flowering remains elusive. Dynamic fluctuations in DNA methylation govern the transcriptional levels of crucial genes pivotal for plant growth and development. In this study, we conducted comprehensive DNA methylation (by whole-genome bisulfite sequencing) and transcriptome (by RNA-seq) analyses on non-flowering leaves, flowering leaves, and spikelets of Moso bamboo. Our findings revealed a notable reduction in the overall DNA methylation level, particularly CHH methylation, from leaves to spikelets, influencing the expression of differentially regulated genes. Notably, we identified DNA methylation as a regulatory mechanism for numerous flowering-related genes, including , , and . Specifically, the gene, a key regulator of the aging pathway, exhibited hypomethylation and a high expression level in spikelets. Conversely, displayed transcriptional silencing attributed to hypermethylation in the CHH context in the leaves of non-flowering plants. DNA methylation may affect the flowering mechanism of Moso bamboo by regulating the expression of key genes. In summary, our results shed light on the dynamic changes in DNA methylation between leaves and spikelets, unraveling an important epigenetic modification mechanism for flowering in Moso bamboo.","PeriodicalId":13178,"journal":{"name":"Horticultural Plant Journal","volume":null,"pages":null},"PeriodicalIF":5.7,"publicationDate":"2024-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141768946","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
