The study identifies the transcription factor MdBRC1 as a key inhibitor of bud growth during the ecodormancy phase in apple (Malus domestica), directly regulating dormancy‑associated genes and interacting with the flowering promoter MdFT2 to modulate bud break. Comparative transcriptomic analysis and gain‑of‑function experiments in poplar demonstrate that MdFT2 physically binds MdBRC1, attenuating its repressive activity and acting as a molecular switch for the transition to active growth.

The study profiled root transcriptomes of Arabidopsis wild type and etr1 gain-of-function (etr1-3) and loss-of-function (etr1-7) mutants under ethylene or ACC treatment, identifying 4,522 ethylene‑responsive transcripts, including 553 that depend on ETR1 activity. ETR1‑dependent genes encompassed ethylene biosynthesis enzymes (ACO2, ACO3) and transcription factors, whose expression was further examined in an ein3eil1 background, revealing that both ETR1 and EIN3/EIL1 pathways regulate parts of the network controlling root hair proliferation and lateral root formation.

The study introduced full-length SOC1 genes from maize and soybean, and a partial SOC1 gene from blueberry, into tomato plants under constitutive promoters. While VcSOC1K and ZmSOC1 accelerated flowering, all three transgenes increased fruit number per plant mainly by promoting branching, and transcriptomic profiling revealed alterations in flowering, growth, and stress‑response pathways.

The study introduces a CRISPR/Cas9‑based restoration system (CiRBS) that reactivates a disabled luciferase reporter (LUC40Ins26bp) in transgenic Arabidopsis, enabling long‑term single‑cell bioluminescence monitoring. Restoration occurs within 24 h after particle‑bombardment‑mediated CRISPR delivery, with ~7 % of cells regaining luminescence and most restored cells carrying a single correctly edited chromosome, facilitating reliable analysis of cellular gene‑expression heterogeneity.

The study used CRISPR/Cas9 to create rice lines with one to three tandem copies of the OsMADS18 gene and confirmed copy-number through high‑throughput qPCR. Incremental increases in OsMADS18 copy number produced proportional rises in transcript levels and corresponding enhancements in leaf blade and culm length, showing that gene dosage can be leveraged to fine‑tune agronomic traits.

The authors adapted OpenPlant kit CRISPR/Cas9 tools to enable multiplex gRNA expression from a single transcript using tRNA sequences in the liverwort Marchantia polymorpha, markedly enhancing editing efficiency and scalability. They coupled this vector system with a simplified, optimized thallus transformation protocol, providing a rapid and versatile platform for generating CRISPR/Cas9 mutants and advancing functional genomics in this model species.

The study investigated how molecular factors determine the developmental fate of axillary buds (AXB) in Fragaria vesca, distinguishing between stolon formation and branch crown development. By combining phenotypic analysis of AXB development with RNA‑seq of undifferentiated buds across three genotypes, the authors identified FveBRC1 as a key regulator, and confirmed its role using CRISPR/Cas9‑generated brc1 mutants. These findings enhance understanding of AXB fate control and its impact on strawberry fruit yield.

The study investigated how Arabidopsis thaliana SR protein kinases (AtSRPKs) regulate alternative RNA splicing by using chemical inhibitors of SRPK activity. Inhibition with SPHINX31 and SRPIN340 caused reduced root growth and loss of root hairs, accompanied by widespread changes in splicing and phosphorylation of genes linked to root development and other cellular processes. Multi‑omics analysis (transcriptomics and phosphoproteomics) revealed that AtSRPKs modulate diverse splicing factors and affect the splicing landscape of numerous pathways.

The study investigates the role of the Arabidopsis transcription factor AtMYB93 in sulfur (S) signaling and root development, revealing that AtMYB93 mutants exhibit altered expression of S transport and metabolism genes and increased shoot S levels, while tomato plants overexpressing SlMYB93 show reduced shoot S. Transcriptomic profiling, elemental analysis, and promoter activity assays indicate that AtMYB93 contributes to root responses to S deprivation, though functional redundancy masks clear phenotypic effects on lateral and adventitious root formation.

The study applied a CRISPR/Cas9 multiplex guide RNA strategy to delete entire open reading frames of four reproductive genes in Arabidopsis thaliana, achieving homozygous deletions already in the T1 generation with rates of 8.3–30%. Deletion efficiencies correlated with DeepSpCas9 prediction scores, and phenotypic analyses revealed unexpected effects of residual gene fragments on fertilization and seed development.
