Summary: This study provides a molecular interpretation for the starch-statolith hypothesis by revealing the role of phosphorylation-mediated interaction between LAZY proteins and amyloplasts in gravity sensing. It also demonstrates how this interaction influences root differential growth through asymmetrical auxin distribution.

Summary: The hydrodynamic effects of macromolecular crowding inside cells were studied using polymers as crowding agents in vitro. It was found that confinement of polymers inside cell-sized droplets affected the diffusion of small molecules. A method based on digital holographic microscopy was developed to measure the diffusion of polystyrene microspheres confined within lipid vesicles containing a high concentration of solute. The study revealed that diffusion inside and outside the vesicles was the same for sucrose or dextran prepared below the critical overlap concentration, but slower for poly(ethylene glycol) above the critical overlap concentration, suggesting potential effects of confinement on crowding agents.

Summary: This paper proposes a mechano-sensing model to explain the root-waving phenomenon in Arabidopsis, which combines the friction induced by gravitropism, the elasticity of the root, and the anchoring of the root to agar by thin hairs. By performing experiments and analyzing the results, the researchers demonstrate that the model can explain the effect of inclination angles on the wavelength and other properties of growing roots. They also show that the prevalence of waving in different plant species is related to root thickness, as predicted by the model.

Summary: Two-point microrheology (TPM) is used to infer material properties of complex fluids from the correlated motion of hydrodynamically interacting probes embedded in the medium. However, previous TPM theory breaks down in confined media, and a new theory is required to account for confinement effects.

Summary: Gravity is a fundamental environmental cue that affects plant development, and it is sensed by specialized cells called statocytes. These cells convert gravity information into biochemical signals, which lead to asymmetric auxin distribution and drive asymmetric cell division/expansion in plant organs. The anti-gravitropic offset (AGO) has been proposed as a hypothetical mechanism to determine the gravitropic setpoint angle (GSA). Gravitropism and AGO share a common gravity-sensing mechanism in statocytes.

Summary: The study demonstrates that synthetic plant tissue analogs (PTAs) can mimic the closed-cell structure and osmotic actuation of non-vascular plant tissue, enabling the emergence of turgor-pressure-induced stiffness and leading to more forceful swelling deformations. PTAs consist of saltwater droplets embedded within PDMS walls, and reach equilibrium in water governed by initial osmolyte concentration and cell wall mechanical response.

Summary: Gravity determines the shape and functions of body tissues in plants and animals, and cellular response to gravity is an active process of mechanotransduction. Despite sharing common mechanisms, each species has its own way of sensing and responding to gravity. Understanding cellular responses to gravity is important not only for life on Earth, but also for laying the foundation for living in space in the age of Mars exploration.

Summary: The study describes a model capable of replicating root growth behaviors and analyzes the role of circumnutation movements in response to environmental cues. The research reveals that circumnutations emerge under gravitropic stress and are a behavioral strategy for roots to detect and react to resource gradients, with an internal oscillator regulating their parameters based on environmental resource perception.

Summary: During the late stage of stomatal development, FOUR LIPS (FLP/MYB124) and MYB88 transcription factors limit guard mother cell division and repress cell-cycle genes' transcripts. FBS4, an F-box protein preferentially expressed in epidermal stomatal precursor cells, regulates stomatal development through post-translational regulation via the ubiquitin-26S proteasome pathway. It interacts with CYCA2;3 and promotes its degradation.

Summary: The study reveals a direct functional link between salt stress and a miR169q-NF-YA8 regulatory module in maize, showing that ZmmiR169q plays a role in responding to stress-induced ROS signals, and ZmNF-YA8 can be harnessed as a resource for developing salt-tolerant crop varieties by transcriptionally activating the expression of the efficient antioxidant enzyme PEROXIDASE1.

Summary: Appropriate flowering time is crucial for plant reproductive success. This study demonstrates that calcium-dependent protein kinase 32 (CPK32) regulates flowering time by affecting the alternative polyadenylation of FLOWERING CONTROL LOCUS A (FCA) and altering the transcription of FLOWERING LOCUS C (FLC), resulting in late flowering and enhanced FLC expression in the CPK32 knockdown mutant.

Summary: Gravity-induced root curvature relies on the asymmetric distribution of auxin, which is regulated by the concerted activities of PIN and AUX1 proteins. However, the mechanism underlying the establishment of auxin gradient remains unclear. In this study, a mutant with abnormal root growth and impaired gravitropic response was identified. The gene responsible for this phenotype encodes AtURI, a protein involved in endomembrane trafficking and auxin distribution regulation. AtURI interacts with PFDs to modulate PIN2 recycling and auxin distribution in roots.

Summary: A transgenic maize carrying three exogenous genes has been developed to protect against insects and weeds. The transgenic maize showed strong toxicity against three major species of Lepidoptera insects and exhibited high tolerance to glyphosate. It has been confirmed that the three genes were successfully expressed in various tissues at different developmental stages of the transgenic maize.
