Summary: TFIIB is a general transcription factor that plays a crucial role in RNA polymerase II activity. In plants, the TFIIB-related protein family, including BRP5/PTF2, has expanded greatly. This study revealed the essential role of BRP5/PTF2 in pollen germination and embryogenesis in Arabidopsis and its impact on pollen development and grain formation in rice. These findings highlight the importance of BRP5/PTF2 in plant sexual reproduction.

Summary: Molecular and cellular characterization of callus formation in rice reveals that callus derived from the scutellum follows an embryo-like developmental program, while callus derived from the vasculature follows a root organogenesis program. The auxin signaling pathway triggers cell division in the scutellum's epidermis to form an embryo-like structure and initiate callus formation. Specific genes, such as OsLEC1 and OsIAA11, are involved in regulating callus initiation from scutellum and vasculature, respectively.

Summary: The study reveals that transcription initiation by RNA Pol II at gene promoters requires formation of the PIC, with a key role played by the Mediator complex. On chromatin, TFIID/TBP, Mediator, and RNA Pol II efficiently assemble into a short-lived PIC within seconds. Nucleosome exclusion of PIC highlights the importance of chromatin remodeling in regulating promoter accessibility.

Summary: The different forms of BnMicEmUP gene are significantly upregulated in embryogenic microspores of Brassica napus, indicating that these proteins are likely transcription factors localized in chloroplasts and overexpression leads to increased sensitivity of plant seedlings to exogenous hormone abscisic acid.

Summary: Tapetal programmed cell death (PCD) is crucial for pollen development, and the MYB2 transcription factor regulates tapetal PCD by activating the expression of proteases CEP1 and beta VPE, which are involved in pollen vitality. Downregulation of MYB2 results in delayed tapetal degeneration, defective pollen, and decreased pollen vitality.

Summary: This study generated a protein-protein interaction network between phytoplasma effectors and Arabidopsis thaliana transcription factors. The results showed widespread interactions between phytoplasma effectors and host transcription factors, especially those involved in host developmental processes. Comparison with other host-pathogen protein interaction networks revealed that phytoplasma effectors have unusual targets, indicating a unique and unusual infection strategy employed by phytoplasmas.

Summary: Members of the FOS protein family play important roles in regulating gene expression and are involved in pathological conditions. Using zebrafish as a model, this study found that zebrafish FOS orthologs exhibit distinct spatiotemporal expression patterns during embryonic development and in adult tissues, and are regulated by oncogenic signals. This suggests that zebrafish can serve as an alternate model for studying the regulation and functions of Fos proteins.

Summary: Parental contributions affect early embryogenesis by regulating maternal resources distribution to offspring. A new study in Arabidopsis thaliana shows that signaling components from maternal sporophytic tissues and paternal gametes converge in zygotes to promote elongation of the extraembryonic suspensor, supporting embryo development.

Summary: EAR motif-containing transcription repressors play an important role in regulating plant growth, development, and responses to biotic and abiotic stresses. In this study, AtEAU1 and AtEAU2 were identified as ABA-responsive genes that negatively regulate ABA responses in Arabidopsis by regulating the expression of key regulator genes in the ABA signaling pathway.

Summary: The study demonstrates that sulfur fertilization can enhance nitrogen-use efficiency in wheat crops and reduce the amount of gliadin proteins, suggesting a relationship between soil sulfur levels and wheat-induced human pathologies. The research highlights the impact of sulfur deficiency on both productivity and population health in modern farming systems.
