However, the mechanisms underlying the biogenesis and development of RPs remain unclear. In this study, two latex-specific <i>cis</i>-prenyltransferases (CPTs), TkCPT1 and TkCPT2, were identified in <i>Taraxacum kok-saghyz</i>, with almost identical orthologues retained across other <i>Taraxacum</i> species. For the first time, <i>Tkcpt1</i> single and <i>Tkcpt1/2</i> double mutants were successfully generated using the CRISPR/Cas9 system. Rubber biosynthesis was significantly depressed in <i>Tkcpt1</i> mutants and completely blocked in <i>Tkcpt1/2</i> mutants. The absence of RPs in the <i>Tkcpt1/2</i> was confirmed using oil red O and Nile red staining, high-speed centrifugal stratification, cryo-SEM and TEM on fresh latex or laticifer cells. Transcriptomic and proteomic analyses revealed that, in the latex of <i>Tkcpt1/</i>2, rubber biosynthesis was blocked at the protein level, while metabolomic profiling indicated an enrichment of lipids and terpenoids. Furthermore, knockout of <i>TkCPTL1</i>, a latex-specific <i>CPT-like</i> gene that encodes a rubber transferase activator, resulted in outright disruption of rubber biosynthesis and RP ontogeny, a phenotype similar to that of <i>Tkcpt1/2</i> mutants. These findings indicate that rubber biosynthesis is a driving force for the biogenesis and development of RPs, providing new insights into rubber production mechanisms.","PeriodicalId":221,"journal":{"name":"Plant Biotechnology Journal","volume":"16 1","pages":""},"PeriodicalIF":13.8,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143666457","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, the telomere-to-telomere genome of <i>O. javanica</i>, with a size of 1012.13 Mb and a contig N50 of 49.55 Mb, was established by combining multiple sequencing technologies. Comparative genome analysis revealed that <i>O. javanica</i> experienced a recent species-specific whole-genome duplication event during the evolutionary process. Numerous gene family expansions were significantly enriched in the terpenoid biosynthesis process, monoterpenoid, and diterpenoid biosynthesis pathways, which resulted in abundant volatile substance accumulation in <i>O. javanica.</i> The volatile terpenoids of <i>O. javanica</i> showed repellent effects on herbivores.

However, salt stress poses a major challenge to soybean growth and productivity. Therefore, unravelling the complex mechanisms governing salt tolerance in soybean is imperative for molecular breeding of salt-tolerant varieties to improve yield. Maintaining intracellular Na<sup>+</sup>/K<sup>+</sup> homeostasis is one of the key factors for plant salt tolerance. Although some salt tolerance mechanisms involving Na<sup>+</sup> exclusion have been well identified in plants, few studies have been conducted on how K<sup>+</sup> influx controls soybean salt tolerance. Here, we characterized the function of soybean K<sup>+</sup> channel gene <i>GmAKT1</i> and identified GmCBL9-GmCIPK6 complex, which modulated GmAKT1-mediated K<sup>+</sup> uptake under salt stress. Functional studies found that soybean lines <i>GmAKT1</i> overexpressing increased K<sup>+</sup> content and promoted salt tolerance, while CRISPR/Cas9-mediated disruption of <i>GmAKT1</i> soybean lines decreased the K<sup>+</sup> content and showed salt sensitivity. Furthermore, we identified that GmCIPK6 interacted with GmAKT1 and GmCBL9 interacted with GmCIPK6. In addition, Mn<sup>2+</sup>-Phos-tag assays proved that GmCIPK6 could phosphorylate GmAKT1. This collaborative activation of the GmCBL9-GmCIPK6-GmAKT1 module promoted K<sup>+</sup> influx and enhanced soybean salt tolerance. Our findings reveal a new molecular mechanism in soybeans under salt stress and provide insights for cultivating new salt-tolerant soybean varieties by molecular breeding.","PeriodicalId":221,"journal":{"name":"Plant Biotechnology Journal","volume":"15 1","pages":""},"PeriodicalIF":13.8,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143666458","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Capturing the leaf transcriptome of 48 accessions of <i>C. sativa</i> suggests allelic variation for gene expression levels and notably sub-genome dominance, both of which could provide opportunities for crop improvement. Flowering time (FT) is a crucial factor affecting the overall yield of crops. However, our understanding of the molecular mechanisms underlying FT regulation in <i>C. sativa</i> are still limited, partly due to its complex allohexaploid genome.

To address the challenge of selecting clonal seeds, we developed a dual-fluorescence labelling gene switch system using the recombinase <i>Cre/LoxP + FRT</i>. Initially, this system was tested in callus tissue under a constitutive promoter; then, we replaced the promoter with a pollen-specific one to develop the pollen-specific gene switch (PSGS) system. The effectiveness of PSGS in rice pollen was subsequently validated. After confirming its functionality, we co-transformed the PSGS vectors with apomixis vectors in hybrid rice Yongyou 2640 (YE) and Yongyou 4949 (YS) using <i>Agrobacterium</i>-mediated transformation. Finally, we identified 18 <i>MiMe</i> mutants carrying the PSGS; the progeny of 16 lines were all red fluorescence seeds (zygotic embryo).

UDP-dependent glycosyltransferases (UGTs) play a pivotal role in the biosynthesis of glycosides in plants by catalysing the attachment of sugar moieties to various bioactive natural products.

In this study, we identify a regio-specific <i>β</i>-(1,6) glycosyltransferase, UGT94BY1, from <i>Platycodon grandiflorum</i>. UGT94BY1 exhibits broad substrate promiscuity and can transfer up to three sugar moieties to the C6-OH position of the glucosyl group in various triterpenoids and phenolic glycosides, thereby forming <i>β</i>-(1,6) oligoglucoside chains. To elucidate the mechanism underlying its substrate selectivity, we determined the crystal structure of the UGT94BY1 complex with UDP at a resolution of 2.0 Å. Molecular simulations revealed that a critical structural motif, comprising residues N84-M91, S141-L155 and R179-E186, plays a key role in recognizing sugar acceptors and facilitating chain elongation.

Building on our previous findings that female <i>Conogethes punctiferalis</i> (Yellow peach moth, YPM) adults exhibit oviposition avoidance behaviour towards corn infected with <i>Trichoderma asperellum</i>, we further confirmed that corn infected by <i>T. asperellum</i> significantly inhibits the growth and development of YPM larvae. Feeding on infected corn decreases larval gut microbiota diversity, core microbiota abundance and led to differential expression of key genes in juvenile hormone metabolic pathway. Moreover, the content of flavonoid wogonin, a secondary metabolite, was significantly increased in infected corn. In vitro feeding experiments revealed that wogonin negatively impacts YPM larval growth by causing the juvenile hormone accumulation and suppressing the abundance of core gut microbial strains.

However, the current crop breeding process faces multiple challenges and limitations, especially in genotypic evaluations. Traditional methods for seed genotyping remain labour-intensive, time-consuming and cost-prohibitive outside of large-scale breeding programs. Here, we present a handheld microneedle (MN)-based seed DNA extraction platform for rapid, non-destructive and in-field DNA isolation from crop seeds for instant marker analysis. Using soybean seeds as a case study, we demonstrated the use of polyvinyl alcohol (PVA) MN patches for the successful extraction of DNA from softened soybean seeds. This extraction technology maintained high seed viability, showing germination rates of 82% and 79%, respectively, before and after MN sampling. The quality of MN-extracted DNA was sufficient for various genomic analyses, including PCR, LAMP and whole-genome sequencing. Importantly, this MN patch method also allowed for the identification of specific genetic differences between soybean varieties. Additionally, we designed a 3D-printed extraction device, which enabled multiplexed seed DNA extraction in a microplate format. In the future, this method could be applied at scale and in-field for crop seed DNA extraction and genotyping analysis.","PeriodicalId":221,"journal":{"name":"Plant Biotechnology Journal","volume":"14 1","pages":""},"PeriodicalIF":13.8,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143660379","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
