Summary: This study reveals the important role of auxin signaling in regulating the diameter of lateral roots in plants. The protein DRP is identified as a key factor in controlling lateral root diameter. The upregulation of auxin signaling in lateral root primordia promotes the expression of a positive regulator, OsWOX10, leading to an increase in lateral root diameter.

Summary: The process of lateral root formation involves asymmetric periclinal divisions of small central cells and differences in mother cell volume during anticlinal vs. periclinal divisions. Additionally, cells undergoing repeated anticlinal divisions do not experience a reduction in cell volume, despite becoming shorter. Furthermore, cells undergoing periclinal divisions exhibit strong cell expansion.

Summary: The plasticity of root system architecture is crucial for plants to adapt to different environmental stresses, mainly regulated by the phytohormone auxin. Lateral root development, which is controlled by auxin signaling, plays a major role in root system architecture. This study reveals that the nucleo-cytoplasmic distribution of the negative regulators of auxin signaling, IAA12 and IAA19, determines lateral root development under various abiotic stress conditions. The cytoplasmic localization of IAA12 and IAA19 enforces auxin signaling output and promotes lateral root development.

Summary: In plant meristems, tissue-wide maturation gradients in coordination with specialized cell networks establish developmental phases for indeterminate growth. Single-cell transcriptomics was used to reconstruct the developmental trajectory of protophloem in Arabidopsis thaliana roots, revealing the role of PHLOEM EARLY DNA-BINDING-WITH-ONE-FINGER (PEAR) transcription factors in lineage bifurcation and differentiation.

Summary: The control of size and shape is crucial during organogenesis, and tooth formation is a complex process that fine-tunes the size and shape of teeth. Ror2-mediated noncanonical Wnt signaling plays a crucial role in regulating root development size in mouse molars, with Cdc42 potentially acting as a downstream mediator. Activation of Cdc42 can restore cell proliferation and partially rescue root development size defects in Ror2 mutant mice.

Summary: LR positioning and development are regulated by auxin production, transport, and inactivation. This study demonstrates the impact of GH3-type auxin conjugating enzymes and DAO1 in LR development. The gh3hex mutants exhibit increased LR density due to enhanced initiation and faster progression, with GH3 activities controlling LR formation. GH3-mediated auxin inactivation attenuates LR development by modulating meristem activities and apical meristem size, resulting in accelerated auxin response oscillations and increased LR initiation rates.

Summary: Root development is regulated by plant hormones, transcription factors, and recently identified small peptides and their receptors. Small peptides bind to receptors, inducing signaling for cell-to-cell communication and coordination of root development. The interconnection between peptide signaling and conventional phytohormone signaling, as well as the diversity of peptide-receptor interactions, have been discussed in recent studies.

Summary: Fine control of beta-catenin is crucial for Hertwig's epithelial root sheath (HERS) integrity and junctional protein expression, which play pivotal roles in tooth root formation. Stabilization of beta-catenin promotes unfragmented HERS formation and prevents HERS dissociation, while its destabilization leads to premature disruption of HERS and interrupted root elongation.

Summary: Plants produce a wide variety of sterols through complex biosynthetic pathways, which play crucial roles in plant growth hormones and signal transduction. While some enzymatic steps are evolutionarily conserved, there are also entirely different enzymes involved in the biosynthetic pathways, which has important implications for the use of plant-specific sterol biosynthesis inhibitors.

Summary: Lateral roots play a crucial role in nutrient uptake and are influenced by nutrient availability. Nitrogen appears to have a clear impact on lateral root formation, while the control mechanisms for other nutrients remain less understood. This review highlights the importance of nutrient signaling pathways, particularly nitrogen, in regulating lateral root development.

Summary: Auxin plays a crucial role in the development of land plants and brown seaweeds, and the PIN and PILS transporter families may have evolved prior to the canonical auxin response pathway. The conservation of PILS-mediated auxin transport and the existence of auxin function in unicellular algae suggest that auxin function predates multicellularity.

Summary: This study reveals that the plant hormone abscisic acid (ABA) can regulate cell proliferation and root growth by modulating the subcellular localization of SNF1-RELATED KINASE 1 (SnRK1) in Arabidopsis thaliana. Under normal growth conditions, SnRK1 alpha 1 is localized in the nucleus, promoting cell proliferation and meristem size. However, in response to ABA, SnRK1 alpha 1 translocates to the cytoplasm, leading to the inhibition of TOR and reduced cell proliferation and meristem size. This suggests that the subcellular localization of SnRK1 is a crucial mechanism for plants to respond to environmental changes.

Summary: This study examined root bifurcation in the lycophyte Selaginella moellendorffii and found that the initial cells in the root meristem are irregular in shape rather than tetrahedral as previously assumed. The study also identified a subset of core meristem genes and suggested the presence of conserved pathways in the control of meristem and root stem cell establishment or maintenance. These findings contribute to a better understanding of root formation and development in plants.

Summary: During root exploration, roots adapt to different conditions and interact with their environment. Asymmetric molecular patterns guide directional root growth, but the mechanisms of their establishment and dynamic regulation are not well understood. Asymmetric gradients of the phytohormone auxin are established through polarized auxin transporters, mainly during root gravitropism. GOLVEN-ROOT GROWTH FACTOR 1 INSENSITIVE signaling in lateral root cap cells plays a crucial role in root gravitropism by regulating the plasma membrane abundance of PIN-FORMED2 in Arabidopsis.

Summary: CNGC2 has been implicated in plant immunity and Ca2+ signaling, but also plays a role in auxin signaling regulation. Mutants of cngc2 display defects in gravitropism and auxin response, with higher levels of endogenous auxin. These phenotypes can be suppressed by mutations in auxin biosynthesis genes, suggesting a tight relationship between CNGC2 and auxin homeostasis.
