    In plants, the functional characterization of essential genes is often hindered by the lethality associated with complete loss-of-function alleles. Here, we present a genome editing-based strategy to generate viable hypomorphic alleles through selective removal of the translation start codon. Using Arabidopsis thaliana NON-SMC ELEMENT 1, which encodes a conserved component of the Structural Maintenance of Chromosomes (SMC) 5/6 complex involved in DNA repair and genome stability, as a model, we generated CRISPR-Cas9-edited alleles lacking the start codon. These homozygous mutants exhibited severe developmental defects, including stunted growth and failure to form true leaves. Moreover, they displayed molecular hallmarks of genome instability, such as increased DNA fragmentation, upregulation of DNA repair and cell cycle checkpoint genes, and root meristem cell death. Complementation assays using wild-type and mutated NSE1 genomic constructs confirmed that these alleles retained partial gene function. Overall, the use of start codon removal as an editing strategy is a robust and broadly applicable approach for generating hypomorphic alleles without relying on transcript-level manipulations, such as RNAi. This work therefore provides a practical demonstration of a novel editing strategy for dissecting the functions of essential genes that are otherwise genetically intractable. Consequently, this approach expands the functional genomics toolkit and opens new avenues for basic plant biology and advanced biotechnological applications.

  • The transcriptional repressors IAA5 and IAA29 participate in DNA damage-induced stem cell death in Arabidopsis roots. International journal

    Plants generate organs continuously during postembryonic development. Thus, their ability to preserve stem cells in changing environments is crucial for their survival. Genotoxic stress threatens genome stability in all somatic cells. However, in the meristem, only the stem cells actively die in response to DNA damage, followed by stem cell replenishment that guarantees genome stability in these cells. Cytokinin biosynthesis-induced inhibition of downward auxin flow participates in DNA damage-induced stem cell death in roots. Without this system, stem cell death occurs at a reduced but significant level, suggesting another mechanism governing the DNA damage response in stem cells. Here, we demonstrate that in response to DNA double-strand breaks, the AUXIN/INDOLE-3-ACETIC ACID (Aux/IAA) family members IAA5 and IAA29, encoding negative regulators of auxin signaling, are induced in Arabidopsis (Arabidopsis thaliana) roots. The transcription factor SUPPRESSOR OF GAMMA RESPONSE 1 directly induces their expression as an active response to DNA damage. In the iaa5 iaa29 double mutant, DNA damage-induced stem cell death is greatly suppressed, while it is fully restored by the expression of a stable form of IAA5 in vascular stem cells. Our genetic data reveal that reduced auxin signaling around the stem cell niche, caused by IAA5 and IAA29 induction and enhanced cytokinin biosynthesis, is a prerequisite for cell death induction, thus playing a central role in maintaining genome integrity in root stem cells.

  • SUPPRESOR OF GAMMA RESPONSE 1 promotes early onset of endoreplication upon DNA double-strand breaks by inducing CCS52A1 expression in Arabidopsis roots.

    Living organisms are constantly at the risk of DNA damage caused by factors such as DNA replication errors, reactive oxygen species, and UV radiation. In plants, DNA damage activates the NAC-type transcription factor SUPPRESSOR OF GAMMA RESPONSE 1 (SOG1) that governs DNA damage responses such as cell cycle arrest, stem cell death, and early onset of endoreplication. However, molecular mechanisms underlying the early induction of endoreplication onset in response to DNA damage remain elusive. In this study, we show that CELL CYCLE SWITCH 52 A1 (CCS52A1), an activator of the APC/C E3 ligase, plays a major role in the early onset of endoreplication in response to DNA double-strand breaks (DSBs) in Arabidopsis roots. Upon DSBs, SOG1 directly binds to the CCS52A1 locus, thereby inducing its expression. Moreover, early transition to endoreplication in response to DSBs is suppressed in ccs52a1 knockout roots. Our data propose that increased polyploidy may function as a unique adaptative mechanism to genotoxic stress in plants.

  • DNA double-strand breaks enhance brassinosteroid signaling to activate quiescent center cell division in Arabidopsis

    Abstract

    In Arabidopsis roots, the quiescent center (QC), a group of slowly dividing cells located at the center of the stem cell niche, functions as an organizing center to maintain the stemness of neighboring cells. Recent studies have shown that they also act as a reservoir for backup cells, which replenish DNA-damaged stem cells by activating cell division. The latter function is essential for maintaining stem cells under stressful conditions, thereby guaranteeing post-embryonic root development in fluctuating environments. In this study, we show that one of the brassinosteroid receptors in Arabidopsis, BRASSINOSTEROID INSENSITIVE1-LIKE3 (BRL3), plays a major role in activating QC division in response to DNA double-strand breaks. SUPPRESSOR OF GAMMA RESPONSE 1, a master transcription factor governing DNA damage response, directly induces BRL3. DNA damage-induced QC division was completely suppressed in brl3 mutants, whereas QC-specific overexpression of BRL3 activated QC division. Our data also showed that BRL3 is required to induce the AP2-type transcription factor ETHYLENE RESPONSE FACTOR 115, which triggers regenerative cell division. We propose that BRL3-dependent brassinosteroid signaling plays a unique role in activating QC division and replenishing dead stem cells, thereby enabling roots to restart growing after recovery from genotoxic stress.

  • Cytokinin signaling promotes root hair growth by directly regulating <i>RSL4</i> expression

    Abstract

    Root hairs are single-celled tubular structures produced from the epidermis, which play an essential role in water and nutrient uptake from the soil. Therefore, root hair formation and elongation are controlled not only by developmental programs but also by environmental factors, enabling plants to survive under fluctuating conditions. Phytohormones are key signals that link environmental cues to developmental programs; indeed, root hair elongation is known to be controlled by auxin and ethylene. Another phytohormone, cytokinin, also affects root hair growth, while whether cytokinin is actively involved in root hair growth and, if so, how it regulates the signaling pathway governing root hair development have remained unknown. In this study, we show that the two-component system of cytokinin, which involves the B-type response regulators ARABIDOPSIS RESPONSE REGULATOR 1 (ARR1) and ARR12, promotes the elongation process of root hairs. They directly upregulate ROOT HAIR DEFECTIVE 6-LIKE 4 (RSL4) encoding a basic helix-loop-helix (bHLH) transcription factor that plays a central role in root hair growth, whereas the ARR1/12-RSL4 pathway does not crosstalk with auxin or ethylene signaling. These results suggest that cytokinin signaling constitutes another input onto the regulatory module governed by RSL4, making it possible to fine-tune root hair growth in changing environments.

    Endoreduplication, a modified cell cycle process in which the cellular DNA level increases without subsequent cell division, is a key component of growth and development of plants. CCS52A1, a substrate-specific activator of the anaphase promoting complex/cyclosome (APC/C), is essential for the transition from mitosis to endoreduplication. Here, we show that DNA-binding with one finger (Dof) transcription factors directly regulate the transcription of the <i>CCS52A1</i> gene. Dof proteins are plant-specific transcription factors involved in plant growth and development processes, such as phytohormone and light signaling, defense response, and seed germination. We performed yeast one-hybrid screening using an <i>Arabidopsis</i> transcription factor library and identified several Dof transcription factors as novel <i>CCS52A1</i> promoter-binding proteins. Protoplast transient assay showed that the Dof proteins, such as CDF1, CDF2, CDF3, and COG1, function as transcriptional repressors of <i>CCS52A1</i>. All of these Dof transcription factors were localized to the nucleus. Our data imply that CDF1, CDF2, CDF3, and COG1 control plant growth and development through the regulation of <i>CCS52A1</i> expression.

    In this study, we revealed the mechanisms underlying the transition from cell division to cell differentiation by conducting functional analyses of KRPs, which are involved in degradation of B-type response regulators, and by analyzing the epigenetic regulation in triggering DNA polyploidization in roots. We found that some KRPs are expressed in the transition zone in roots and play an important role in an early onset of cell differentiation in response to DNA damage. Our results also indicated the possibility that auxin controls chromatin structure, thereby being associated with the transition from cell division to cell differentiation.
