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: This study found that Arabidopsis seedlings growing on low concentrations of galactose exhibit abnormal root development, including incomplete cell division, cell wall stubs, binuclear cells, and lignified root tips. Further microscopy analysis revealed that galactose has a significant impact on root development. Comparing the galactose toxicity phenotype with those of cytokinesis mutants and plants treated with appropriate inhibitors, the interference with intracellular vesicle transport or cell wall biogenesis is speculated as the potential cause of galactose toxicity.

Summary: MAX2 signaling affects the competence of root explants for callus formation and shoot regeneration. The defective shoot regeneration of max2 is attributed to delayed callus primordium formation, resulting in less material for shoot regeneration. Additionally, the phenotype of in vitro shoot regeneration in max2 may be related to a defect in KAI2 signaling rather than DWARF14.

Summary: DCG, a phenylpropanoid-derived plant metabolite, is claimed to have cytokinin-substituting and cell-division-promoting activities. However, our experiments showed no morphological changes or transcriptional shifts in Arabidopsis seedlings, indicating that DCG does not have the reported activities. Furthermore, no evidence was found to support the uptake of DCG by plant cells, explaining the lack of observable activity. Despite an increase in DCG content in plant tissue, there was no demonstrated activity for this metabolite. These findings call for a reevaluation of the attributed cytokinin-substituting and cell-division-promoting activities of DCG.

Summary: Roots are able to sense and respond to elevated temperature independently of shoot-derived signals. This response is mediated by an unknown root thermosensor that uses auxin as a messenger to relay temperature signals to the cell cycle. Growth promotion is primarily achieved by increasing cell division rates in the root apical meristem, dependent on de novo local auxin biosynthesis and temperature-sensitive organization of the polar auxin transport system.

Summary: The development of lateral roots begins with asymmetric cell divisions in lateral root founder cells in the root's pericycle. The reorientation of the cell division plane occurs simultaneously with changes in cell shape and requires coordination with the neighboring endo-dermis. Recent studies suggest that dynamic changes in the cytoskeleton and possibly the cell wall play a role in properly orienting and positioning the cell division plane.

Summary: The study aimed to investigate morpho-anatomical aspects, metabolic changes of proteins, antioxidant substances, and phenolic compounds in embryogenic callus (EC) and degenerative embryogenic callus (DEC). The ability to form somatic embryos was associated with the softness of the EC and higher concentrations of proteins, GSH, and ASC compared to DEC. The DEC showed a loss of embryogenic competence and had accumulations of oxidized ascorbic acid, H2O2, phenolic compounds, and naringenin.

Summary: In this article, the authors discuss how breeding for specific root traits can improve crop resilience in Africa. They provide three case studies that demonstrate the effectiveness of root traits in enhancing crop production and adapting to climate change. The studies show that increasing root whorl number, longer and denser root hairs, and water-saving strategies can improve the acquisition efficiency and yield of crops. The researchers also discuss the importance of evaluating the utility of root traits and making root trait selection feasible for breeders.

Summary: Lateral root organogenesis is crucial for the development of a plant's root system. The early phase of cell proliferation in lateral root formation leads to the establishment of a root meristem-like structure. PUCHI gene plays a role in repressing the ectopic establishment of meristematic cells during early stages of lateral root development. These findings provide insights into the gene network that regulates timing and patterning in lateral root formation.

Summary: Climate change is primarily driven by increasing CO2 concentrations, resulting in higher temperatures, temperature extremes, and reduced water availability. Although higher CO2 and temperatures may benefit plant biomass production, climate change poses significant challenges to plant life cycles, leading to food insecurity. Investigating the molecular mechanisms of plant adaptation to climate change is therefore crucial.
