Summary: The stigma, an essential tissue for pollination in angiosperms, involves multiple transcription factors in Arabidopsis thaliana. The NGATHA (NGA) and HECATE (HEC) transcription factors interact physically in the apical gynoecium and are crucial for stigma differentiation through upregulating other key genes. This study suggests a nonhierarchical regulatory scenario in which the combinatorial action of different transcription factors provides precise temporal and spatial specificity for developmental outputs.

Summary: The success of angiosperms, the most successful group of land plants, is mainly attributed to the gynoecium, the innermost whorl of the flower. In Arabidopsis, the gynoecium is formed by two fused carpels, and a quasi-meristem called the carpel margin meristem plays a crucial role in its development. The study of gynoecium development, which is important for the production of seeds and fruits, has been a significant task for the scientific community. This review presents recent advances in Arabidopsis gynoecium patterning and highlights unanswered questions.

Summary: By comparing the fruit development and gene expression patterns of multiple species, we found that the expression of core fruit development genes is somewhat conserved. These genes play important roles in cell division, cell wall synthesis, and developmental patterning. In addition, we identified accessory genes with conserved expression patterns within different fruit types, highlighting the significant differences between these phenotypic classes.

Summary: This study revealed the functions of the genes CsSPT and CsALC in regulating fruit cavity formation and female fertility determination in cucumber. These two genes mediate the expression of genes involved in transmitting tract development, auxin-mediated signaling, and cell wall organization, and redundantly define stigma morphology and the pollen tube extension path. This ensures female fertility and carpel fusion in cucumber.

Summary: Floral homeotic genes in angiosperms, such as OsMADS13 in rice, play a crucial role in determining ovule identity. The interaction between OsMADS13 and other genes, like those in the SEP family, may control a common set of target genes involved in ovule development. This study sheds light on the regulatory pathways in rice gynoecium development and provides insights into the role of OsMADS13 as a repressor of the carpel pathway during ovule development.

Summary: The transient expression system developed for apple protoplasts shows that the AtUBQ10 and MdUBQ10 promoters are more efficient in driving gene expression compared to the CaMV 35S promoter. Using this system, it was demonstrated that active AtMKK7ac could activate signaling cascades and regulate phosphorylation and stability of MdWRKY33 in apple. The system also allowed for the reconstitution of ligand-induced interactions and regulation of AvrRpt2 stability involving auxin and the immune regulator RIN4.

Summary: Plants undergo transcriptome reprograming to adapt to daily and seasonal fluctuations in light and temperature conditions. The proper spliceosome assembly, which requires the methylosome complex, is crucial for efficient pre-mRNA splicing. PICLN, a part of the methylosome complex, plays a key role in regulating pre-mRNA splicing and mediating plant adaptation to environmental conditions.

Summary: This research found that winter survival was the direct target of selection during colonization of Japan by Lotus japonicus. Two candidate genes, FERONIA-receptor like kinase (LjFER) and a S-receptor-like kinase gene (LjLecRK), were identified to be required for non-acclimated freezing tolerance and exhibited haplotype-dependent cold-responsive expression. The study suggests that incorporating a conserved growth regulator gene, FER, and a receptor-like kinase gene, LecRK, into the cold-responsive genes contributed to freezing tolerance and local climate adaptation in L. japonicus, providing insights into the genetic mechanisms of perennial herb evolution.

Summary: Transposons are mobile elements that are silenced in order to protect genome integrity. In plants, transposable element-derived inverted repeats (IRs) are often found near genes and affect gene expression. However, the molecular mechanisms of this regulation are still unclear in most cases.

Summary: All flowering plants adjust their reproductive period for successful reproduction. Flower initiation is controlled by various studied factors, while the end of flowering is a less understood process at the genetic or molecular level. Recent progress in understanding the regulation of the end of flowering is presented, highlighting missing aspects for future research and potential biotechnological avenues in crop yield improvement in annual plants.

Summary: Rapid adaptation of weeds to herbicide applications in agriculture through resistance development, particularly the grass Alopecurus myosuroides, is a common phenomenon. Target-site resistances (TSRs) are important for this adaptive response. In this study, we used PacBio HiFi reads to sequence long-range amplicons and resolved them into haplotypes using the PacBio amplicon analysis (pbaa) algorithm in pools of individuals. We recovered most haplotypes from previously sequenced individuals and found common TSR mutations originating from independent soft sweeps in new populations.

Summary: This study aims to explore the genetic regulatory network underlying multicellular trichome development in Aristolochia. By comparing two different morphological species of Aristolochia, we found significant modifications in gene composition, expression, and function compared to model plants. We propose the first hypothetical genetic regulatory network for floral multicellular trichome development in Aristolochia and identify key factors responsible for the presence and specialization of floral trichomes in different species.

Summary: The interactions between microorganisms and their multicellular host are crucial for understanding plant or animal tissues. However, current technology hinders the study of spatial interactions between the host and its colonizing microorganisms. In this study, we introduce spatial metatranscriptomics (SmT), a sequencing-based approach that allows simultaneous characterization of host transcriptome and microbiome at a high spatial resolution. The SmT technique was applied to outdoor-grown Arabidopsis thaliana leaves and revealed tissue-scale hotspots of bacteria and fungi. By analyzing networks, we investigated the spatial interactions between microorganisms from different kingdoms, as well as the host response to microbial hotspots. SmT provides a valuable approach for studying the interplay between host and microbiome.

Summary: A systematic analysis of the requirement for MET1 in different A. thaliana accessions reveals that CG methylation plays a dual role in gene expression. For many genes, CG methylation appears to canalize expression levels, masking regulatory divergence. However, for a smaller subset of genes, CG methylation increases expression diversity beyond genetically encoded differences.
