Summary: Somatic embryogenesis of E. edulis stem explants is not affected by their polarity, and a concentration of 150 mu M PIC in the culture medium results in the highest number of embryos. After 30 days of maturation, the explants should be transferred to a different medium to avoid oxidation. Around 20% of somatic embryos successfully convert into plantlets and can be acclimatized.

Summary: NH4+-mediated accelerated auxin turnover rates lead to transient and local IAA peaks. The distinct auxin pattern in tissues is correlated with the short and highly branched root system adaptations of NH4+-grown plants. The spatiotemporal distribution of auxin may act as a root-shaping signal specific for adapting to NH4+ stress conditions.

Summary: Cell intercalation is a crucial cell behavior involved in morphogenesis and wound healing, which can cause significant tissue deformations. This study introduces a new model to understand the mechanisms of cell intercalation, specifically focusing on the interaction between cell cortices and adhesion molecules.

Summary: Expansins facilitate cell expansion by mediating pH-dependent cell wall loosening. This study investigates the role of expansins in controlling cell wall biomechanical properties in specific tissues and organs in Arabidopsis. The results show that expansins are spatially specific and play a role in regulating cell wall stiffness and growth arrest. The findings propose that expansins orchestrate cell wall biomechanical properties to control root growth.

Summary: The root cortex is responsible for transporting water and nutrients and storing substances, while also determining the fate of epidermal cells. Research has shown that cortical cells do not divide during root apical meristem (RAM) development, but they can be induced to divide by auxin. This finding highlights the crucial role of auxin in determining root cortical cell division.

Summary: In this study, the possible link between SIK1, auxin, PIN, and polarity was explored. The sik1 mutant exhibited abnormal phyllotaxis and gravitropism, and increased sensitivity to exogenous auxin. However, the polarity defects in sik1 are unlikely mediated by PINs, as shown by normal PIN localization patterns and vacuolar degradation in the mutant.

Summary: The research found that exogenous indole butyric acid treatment led to the downregulation of many genes in adult phase leafy cuttings of Malus xiaojinensis, including those involved in phytohormone signaling, carbohydrate metabolism, and cell dedifferentiation. By regulating the interaction between the MxHB13 gene and other regulatory factors, a model for AR formation in adult phase Malus xiaojinensis was proposed.

Summary: The study reveals the antagonistic effects of ethylene and glucose signaling on the self-renewing capacity of stomatal lineage stem cells, providing a framework for understanding cell behavior in the stomatal lineage. The research suggests that developmental information may be encoded in both the spatial and temporal asymmetries of polarity proteins.

Summary: The research reveals the unique mechanism of KIF13A dimerization modulated by Rab22A during RE tubulation, leading to balanced motility and force against multiple dyneins in a molecular tug-of-war to regulate endocytic recycling and cellular homeostasis. This demonstrates that KIF13A motors are fine-tuned at a single-molecule level to function as weak dimers on cellular cargo.

Summary: Polar localization of PIN proteins is crucial for plant development as they regulate the transport of auxin between cells. Signals upstream control subcellular PIN localization to modulate auxin distribution, thereby regulating various aspects of plant development.

Summary: Manipulating the local response and synthesis of the plant hormone auxin revealed the contributions of different cell types to root growth and development. Inhibiting or enhancing auxin signaling in various cell types had significant impacts on root growth, with the most pronounced effects observed in the endodermis.

Summary: During mitosis in higher eukaryotes, chromosome condensation is co-regulated by several gene families, with chromosome size and DNA content scaling with powers close to 1/4, 1/2, and 1 across vertebrate species. The increase in chromosome cross-sectional area with length is hypothesized to be necessary to prevent large chromosome elongations that could slow or stall mitosis. Unlike angiosperms, individual vertebrate karyotypes typically exhibit a wider range of chromosome lengths.
