Summary: In this study, the genotyping of 310 Brassica rapa accessions revealed 19 homozygous and 81 heterozygous putative functional alleles of the flowering time gene BrFLC5. Overexpression of BrFLC5 was found to regulate flowering in Arabidopsis thaliana. The expression level of BrFLC5 was not associated with the G/A polymorphism in the third intron, but rather with a 584-bp insertion in the promoter region. The potential impact of high expression of functional BrFLC5 on premature bolting-resistant lines in B. rapa vegetables is discussed.

Summary: The study used strong winter rapeseed to analyze the floral transition mechanism of germinating seed vernalization, finding that germinating seeds can sense low temperatures and complete vernalization following a low temperature treatment for 56.5 days with a 100% vernalization rate. Furthermore, with prolonged vernalization treatment time, the vernalization rate and fruiting ability increased rapidly, along with changes in membrane lipid oxidation and physiological characteristics. The study also revealed that salicylic acid (SA) content decreased significantly with prolonged vernalization treatment time, showing a negative correlation with the vernalization rate of germinating seeds and suggesting SA's role as a floral repressor in the vernalization process of winter rapeseed germination seeds.

Summary: The study investigated the uptake and translocation of six antibiotics in pak choi, finding that fluoroquinolones had significantly higher accumulation capacity. Roots were found to be the main accumulator of antibiotics, and antibiotic translocation was associated with water transport through xylem vessels controlled by aquaporin activities and transpiration. Overall, the findings provide valuable insights for developing optimal management practices to mitigate antibiotic contamination in vegetables and ensure food safety.

Summary: This study identified 15 LOX genes in turnip, which may be involved in the formation of turnip fleshy roots. Gene duplication analysis showed that expansion of the BrrLOX gene family mainly occurred through tandem and segmental duplication, with strong purifying selection on duplicated genes. Further analysis suggested that the expression of BrrLOX genes may be influenced by stress and phytohormones.

Summary: The study found that aged biodegradable microplastics (BMPs) have more detrimental effects on pakchoi than virgin BMPs, and the co-existence of BMPs and cadmium (Cd) causes greater damages to pakchoi. These findings highlight the potential negative effects of aged BMPs in agricultural systems, especially when combined with heavy metals.

Summary: This study investigated the metabolite composition and variation among a large collection of Brassica rapa genotypes. The researchers identified 346 metabolites belonging to different chemical classes, with 36 of them being confidently assigned and 184 being reported for the first time in B. rapa leaves. The accumulation and variation of metabolites were compared to the phylogenetic distance and showed significant correlation. Four major phylometabolic branches were determined. This study provides the basis for further studies on B. rapa metabolism and nutritional traits improvement.

Summary: This study investigates the gene expression differences between two Chinese cabbage accessions with different bolting behaviors during vernalization. Through transcriptome analysis and WGCNA, it was found that specific pathways such as shoot system morphogenesis and signaling pathways play a role in promoting early bolting, while pathways related to chitin, ABA, and ethylene signaling are involved in late bolting. Hub genes like MTHFR2, CPRD49, AAP8, and specific genes related to flower development were also identified. These findings provide valuable insights for breeders in optimizing Chinese cabbage production.

Summary: Rapid flowering of oilseed-type B. rapa 'LP08' plants is mainly attributed to the nonsense-mediated mRNA decay (NMD)-mediated degradation of BrFLC2 transcripts. In this study, a major QTL associated with vernalization was identified on the upper-arm of chromosome A02 by comparing the transcriptomes of late-flowering Chinese cabbage 'Chiifu' and early-flowering yellow sarson 'LP08'. It was found that BrFLC2 was significantly downregulated in 'LP08' and had two deletion sites, with one resulting in the premature stop codon in BrFLC2 transcript. Cycloheximide treatment further confirmed that the low transcript level of BrFLC2 in 'LP08' was due to NMD.

Summary: The aim of this study was to analyze the glucosinolate content in Choy sum germplasm conserved at the RDA-Genebank. The study found that aliphatic glucosinolates were the most common and aromatic glucosinolates were the least common among the analyzed germplasms. Glucobrassicanapin and progoitrin were identified as highly represented glucosinolates in one of the accessions, which have therapeutic applications.

Summary: Occupation of living space is a driving force of adaptive evolution, especially for aquatic plants. Euryale ferox, a water plant, develops large leaves to compete for space on the water surface. Cell proliferation of the leaves occurs underwater, while cell expansion happens after they grow above water. Analysis of the genome and transcriptome dynamics of E. ferox revealed that genes from a specific sub-genome were more involved in the adaptive evolution of leaf development. Additionally, genes related to cell proliferation, expansion, photosynthesis, and energy transportation were over-retained and showed expression association with leaf development stages.

Summary: Four heterotic QTL and a heterozygous segment for plant weight were identified in heading Chinese cabbage, revealing the significant role of heterosis in yield-related traits. Pseudo-overdominance and synergistic allelic effects from parent line XJD4 appear to play an important role in heterosis for plant weight in Chinese cabbage. These findings provide insights into the molecular mechanisms underlying yield-related traits and heterosis.

Summary: This study evaluates the effects of dominance and niche partitioning on biodiversity-ecosystem functioning (BEF) relationships in grassland systems worldwide. The results indicate that dominance effects, related to the traits of the dominant species, have a significant impact on BEF relationships, while functional diversity (FD) does not affect primary productivity (NDVI).

Summary: Based on recent phylogenetic studies, a new classification system for Brassicaceae is proposed, with improvements at the subfamilial and supertribal levels. The family is now divided into two subfamilies, Aethionemoideae and Brassicoideae. The Brassicoideae is further divided into five supertribes, including Arabodae, Camelinodae, Heliophilodae, and Hesperodae. Additionally, several newly recognized tribes are described, and clarifications are provided for 17 other tribes.

Summary: Orychophragmus violaceus, known as eryuelan in China, is an early-flowering ornamental plant with potential as a high-quality oilseed crop. By sequencing technologies, a 1.3 Gb genome was assembled for O. violaceus, which went through tetraploidization from a diploid progenitor. Comparative analysis suggests subgenome dominance and independent tetraploidization in O. violaceus, which is closely related to the Brassica genus. The findings shed light on polyploidization evolution and functional innovation in O. violaceus.

Summary: Sorghum productivity in arid and semi-arid regions of Africa is greatly hindered by limited water availability. This study investigated the genetic variation in root system architecture (RSA) and its relationship with drought response in Ethiopian sorghum germplasm. Significant genetic variation was observed for most traits examined, and root angle was found to be uncorrelated with other RSA traits. Cluster analysis grouped the germplasm into four different clusters based on RSA traits. These findings suggest that the large variation in RSA traits can be utilized in breeding programs to improve sorghum productivity under drought stress.
