Summary: An unusual gene, BAM7, encoding two functionally distinct proteins has been found in some angiosperms, including maize. These two proteins are encoded by separate genes in Arabidopsis but their functions are not well understood. The maize BAM7 gene produces two transcripts that are independently synthesized, and their predicted proteins have different subcellular localization and functions. This dual-function gene originated at least 400 Mya and has been duplicated and subfunctionalized in several lineages of land plants.

Summary: The study identified 38 homologous genes of ZmCP03 in maize and analyzed the protein motifs, conserved domains, gene structures, and duplication patterns of 39 CPs, revealing their evolutionary relationship and potential functions. The results suggested that ZmCP03 was relatively conservative and stable during evolution. This study provides valuable insights into the role of ZmCP03 in pollen development and germination in maize.

Summary: This study conducted a comprehensive analysis of DDP proteins in the potato genome, identifying 10 DDP genes and studying their characteristics in terms of phylogenetics, gene duplication, expression profiles, and promoter regions involved in stress response. The research revealed that StDDP genes were distributed across different clades, and exhibited various expression patterns in response to heat stress and salt stress. Real-time qPCR results indicated that StDDPs played significant roles in potato growth and development.

Summary: This study identified 140 ZmWRKY proteins encoded by 125 ZmWRKY genes in maize, which were divided into three main groups and further classified into five subgroups. The genes displayed specific exon-intron structures and conserved protein motifs. RNA-seq analysis revealed differential expression patterns of ZmWRKY genes at different developmental stages and under abiotic stress treatments.

Summary: The YABBY gene family, present in all seed plants, plays crucial roles in plant growth and development, including polarity establishment, leaf and flower formation, and response to hormonal signals and environmental stress. Through identification of 364 YABBY genes in 37 Brassicaceae genomes, it was found that these genes are largely conserved across species but exhibit considerable functional divergence.

Summary: In this study, we identified 27 ChemR genes in miiuy croaker and analyzed their characteristics, including gene structure, evolutionary mechanism, and expression levels upon bacterial infection. The results showed that these genes underwent tandem and segmental duplication events during evolution, and teleost fishes' ChemRs may have a higher evolutionary dynamic compared to vertebrates. Additionally, 21 positively selected codons were detected in vertebrate ChemRs under Model 8, and certain genes were significantly up-regulated upon Vibrio harveyi infection, providing valuable information for further functional analysis.

Summary: This study compared the 6mA methylation patterns of four lotus plants using nanopore sequencing and compared them to patterns in Arabidopsis and rice. The results showed that 6mA sites are enriched around transcriptional start sites and positively correlated with gene expression levels in lotus, Arabidopsis, and rice. Additionally, 6mA methylation is more conserved in whole-genome duplicates than in local duplicates. Overall, this study reveals the potential role of 6mA methylation in gene regulatory evolution in plants.

Summary: TAL1 is frequently dysregulated in T-ALL, and its overexpression is associated with unfavorable clinical outcomes. This study found that the tumor suppressor KLF4 can suppress SE-driven TAL1 expression in T-ALL cells by inhibiting the formation of 5' TAL1 super-enhancer. A small molecule inducer of KLF4, APTO-253, exerts an anti-leukemic effect by targeting SE-driven TAL1 expression in T-ALL cells. Induction of KLF4 may be a promising strategy to control TAL1 expression and could serve as a novel treatment for T-ALL patients with poor prognosis.

Summary: The study revealed duplications of MYB12, MYB111, and MYB21 within the Brassicaceae, as well as gene loss of MYB11 and MYB24 within the Brassiceae tribe. It is proposed that polyploidization events have played a role in shaping the evolution of flavonol regulators in the Brassicaceae, especially within the Brassiceae tribe.

Summary: Floral initiation in domesticated apple and other woody perennials can be suppressed by gibberellins. The mechanism behind this repression is still unknown and understanding GA signaling in apple is important for commercial applications. The GA2ox gene family in apple consists of 16 genes, with MdGA2ox2A/2B being potentially involved in flowering repression. This study provides insights into GA signaling, GA2ox gene regulation, and gene expression in apple, which can be applied to the development of new apple cultivars and other tree fruits.

Summary: Genetic engineering has the potential to improve maize productivity, but raises concerns about unintended effects and equivalence with non-GM comparators. Targeted analysis may have limitations in detecting unintended effects in genetically modified organisms. Introducing herbicides and insect resistance genes in a popular maize variety in China showed limited changes in gene and metabolite profiles, with growing environments having a greater impact than gene modification itself. Differences in genetic background had greater effects on molecular profiling than gene modification, emphasizing the importance of considering environmental effects.

Summary: Most protein complex subunits have small to nondetectable fitness effects when duplicated, with few exceptions. Very few gene duplications affect both fitness and protein-protein interactions. Large complexes like the 26S proteasome are protected from gene duplication by regulating protein abundance.
