Summary: Organogenesis in plants relies on a balance between cell division and expansion, with the root serving as an ideal model to study cell proliferation. Cell proliferation activity is mainly restricted to the root apical meristem, and a combination of new tools, experimental strategies, and mathematical models has enhanced our understanding of cell proliferation in the RAM. Further research is needed to explore additional aspects of cell proliferation in plants.

Summary: Salt stress has a severe impact on plant growth and development. Understanding the mechanisms related to growth and development in response to salt stress is crucial for plant tolerance and adaptation. This paper highlights the roles of microRNAs, redox status, reactive oxygen species, nitric oxide, and phytohormones in apical meristems for salt tolerance, as well as the relationship between salt stress response and stem cell homeostasis.

Summary: Phyllotaxis, the geometry of leaf arrangement around stems, determines plant architecture and has evolved independently in major land plant lineages. The study of how asymmetric divisions in single-celled meristems create phyllotactic patterns and whether associated genetic processes are shared across lineages is a key question. The model moss Physcomitrium patens demonstrates that similar molecular regulatory modules have been repeatedly deployed across evolution to drive apical function in convergent shoot forms.

Summary: Over-expression of phytoglobin can alleviate the degradation of the root apical meristem caused by waterlogging through changes in nitric oxide and auxin distribution at the root tip.

Summary: Proteasome dysfunction in plants leads to abnormal development and reduced adaptability to environmental stresses. This study found that proteasome dysfunction downregulated the hypoxia-responsive pathway and impaired plant growth and adaptability to hypoxia stress.

Summary: Distinct from animals, plants maintain organogenesis from specialized tissues called meristems throughout life. The shoot apical meristem (SAM) in the shoot apex produces all aerial organs, and cell signaling within functional domains is crucial for SAM functions. Recent studies on the WUSCHEL-CLAVATA feedback loop and polar auxin transport and signaling have expanded our understanding of SAM homeostasis and organogenesis. Furthermore, single-cell techniques have improved our knowledge of cellular functions in the shoot apex.

Summary: A continuous transition from stem cells to transit-amplifying cells and then differentiated cells is crucial in understanding the development of multicellular organisms. In this study, the researchers focused on the root apical meristem (RAM) in Arabidopsis thaliana and found that the mutation mto2-2 affected threonine synthesis and resulted in the loss of the proliferation domain (PD) in the RAM. Mathematical modeling and molecular markers were used to demonstrate the uncoupling of PD and the transition domain (TD) in the mutant.

Summary: Gene expression is rapidly reconfigured during the cell cycle to carry out specific cellular functions for each phase. The use of fluorescence-activated cell sorting allowed for analysis of gene expression profile in G2/M cells in the growing root and identification of key regulatory factors. SCL28, a transcription factor, was found to play a crucial role in promoting progression through G2/M and modulating cell division plane selection.

Summary: The study found that coumarin induced cyclin B accumulation, which altered the organization of the microtubule cortical array, leading to reduced basipetal transport of auxin to the root apical meristem, causing its accumulation in the maturation zone and stimulating lateral root formation.

Summary: Plant hormones play a key role in regulating root development, involving both embryonic and post-embryonic stages. The terminology and classification criteria for root zonation may have potential ambiguities, requiring further research for clarification.

Summary: This study elucidated the mechanism behind the alleviation of aluminum toxicity on root growth by boron supply in Arabidopsis roots. It was found that boron modifies auxin distribution and transport in Al-exposed roots, with increased auxin content in the root apical meristem and transition zones but decreased content in the elongation zone. This distribution pattern is caused by disrupted basipetal auxin transport due to Al-inhibited PIN2 endocytosis.

Summary: This review discusses the concepts of the quiescent centre (QC) of the root apical meristem (RAM) and their evolution over time, from the formulation by F.A.L. Clowes to contemporary understanding. It explores the usefulness of the QC concept in understanding RAM organization and behavior, focusing on conceptual developments and the role of QC in RAM maintenance and activity from model species to crops.

Summary: Preservation of stem cell functionality during hypoxia is achieved through the activation of the TCA cycle and the retention of starch and carbohydrates by phytoglobin. Maize QC stem cells, despite being highly hypoxic under normal oxygen tension, are vulnerable to hypoxic stress and show impairment in various metabolic processes. Overexpression of PHYTOGLOBIN 1 preserves the functionality of QC stem cells during stress by rewiring their metabolism.
