Wheat seeds are the primary sustenance source. Given the mounting global population and dwindling arable land, enhancing wheat grain yield remains a concern for mankind. A pivotal agronomic trait influencing grain yield is grain weight, which is predominantly contingent on seed size and endosperm components and is regulated by complex and precise molecular networks. Endogenous factors, such as transcriptional and post-translational regulators, exert pivotal influence over seed development. Notably, starch is the main storage component of wheat endosperm, and the starch synthesis-related genes exert an important effect on grain weight. Prior reviews on wheat grain traits have mostly focused on the regulation of grain size, and the contents of such reviews are almost entirely written based on the regulatory network of rice seed size. Although many regulatory mechanisms for various traits are similar in rice and wheat, there are lots of differences in wheat due to its vast and intricate genome. An all-encompassing panorama of the grain weight regulatory network has not yet been comprehensive. This review summarizes the catalog of reported genes, discusses the emerging molecular mechanisms, and delves into regulatory networks to foster a more holistic understanding of the intricate regulation of wheat seed weight.","PeriodicalId":137493,"journal":{"name":"Seed Biology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135058835","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we present the first chromosome-scale genome of <italic>Ipomoea pes-caprae</italic> L (IPC), an exceptionally salt-tolerant plant species of considerable significance due to its medicinal, ecological, and biological attributes. The haplotype IPC genome comprises 15 chromosomes spanning 1.05 GB and includes 34,077 protein-coding genes, exhibiting an impressive completeness of 97.4%. Comparative genomic analysis with non-salt-tolerant <italic>Ipomoea</italic> species has highlighted the prevalence of highly duplicated sequences and genes within the IPC genome. Analysis of gene ortholog expansion, when compared those <italic>Ipomoea</italic> species, reveals that expanded TRD (transposed duplication) and DSD (dispersed duplication) genes are predominantly associated with functions related to salt tolerance. Furthermore, our findings suggest strong correlations between DSD and TRD gene duplication and transposable element (TE) events, implying that TE-induced expansion of repeat genes is a driving force behind gene diversification. Moreover, a time-course RNA-seq analysis unveils the salt response of IPC roots and leaves, showing the involvement of several key salt-tolerance genes exhibiting copy number expansion. These include genes responsible for ion uptake, transportation, and sequestration into vacuoles, as well as genes responsible for the maintenance of DNA and chromosome stability. Given the significant induction of TE events by salt stress in plant genomes, we propose a putative mechanism for the rapid evolution of salt tolerance in IPC. Additionally, this study delves into the metabolic pathway and regulatory mechanisms of Caffeoylquinic acids (CQA), a medicinal component found in IPC.","PeriodicalId":137493,"journal":{"name":"Seed Biology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135609120","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, how protein ubiquitination regulates seed development in high-temperature environments is less understood. Here, a label-free quantiﬁcation identiﬁed 488 lysine modification sites in 246 ubiquitinated proteins in the endosperm of two rice varieties, 9311 and Guangluai4 (GLA4). Under high-temperature stress, the number of significantly up-regulated sites was far greater than down-regulated sites, and 37 ubiquitinated proteins were commonly regulated with the same trend in the two varieties. The sucrose and starch metabolism were greatly over-represented by functional and pathway enrichment analyses. The key functions of ubiquitinated proteins related to starch metabolism are SUS1, SUS2, SUS3, FK and UGPase for sucrose hydrolysis, and AGPL2, AGPL3, AGPS1, AGPS2, GBSSI, BEI, BEIIb, PUL and Pho1 for starch synthesis. Most lysine modification sites were first identified in rice and tended to be up-regulated under heat stress, providing evidence for decreased protein abundance of starch synthesis related enzyme at the ubiquitination level. Predicted 3D models of GBSSI revealed an important role of ubiquitylation sites K462 involved in the interaction between the GBSSI and ligands (SO4 and ADP). Our study provides the first comprehensive view of the ubiquitome in rice seeds, which will provide important insight into the mechanism underlying seed development and grain quality improvement under high-temperature stress.","PeriodicalId":137493,"journal":{"name":"Seed Biology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135705493","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recent reports highlighted that Russia has continually advanced in different maneuver axes and at present, no one can predict when and how the Ukraine conflict will end. For over three months, the conflict has greatly influenced the global economy and sounded the alarm bells for global food safety, especially to those countries which greatly depend on food and chemical fertilizer import from Russia and Ukraine, as well as those countries sensitive to food price variation shock. According to the '2021 GLOBAL REPORT ON FOOD CRISES (GRFC 2022)' by the World Food Program (WFP) and Food and Agriculture Organization of the United Nations (FAO), due to regional conflicts, economic downturn and Covid-19 about 1.93 billion people in 53 countries and regions are facing a food crisis, which is the highest number since 2016, and since 2000 the number has increased by 0.4 billion. Since both Russia and the Ukraine are important countries for grain export, the RussiaUkraine conflict, the reduced agricultural output (particularly grains and oilseeds), and economic sanctions against Russia, have further enhanced the global food crisis. Notably, we are facing great challenges in global food safety. Here, we try to emphasize the influences of the Russia-Ukraine conflict on global food safety in terms of its shortand long-term effects based on our current understooding to date.","PeriodicalId":137493,"journal":{"name":"Seed Biology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115537152","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
