Summary: This study combines the physics of thin elastic plates with feedback control theory to explore how a leaf can remain flat while growing. The researchers find that a linearized feedback theory can effectively suppress long wavelength fluctuations and explain the statistical features observed in the growth of tobacco leaves.

Summary: Shao et al present evidence that GABBR1 is a key functional regulator of murine and human hematopoietic progenitors, showing that GABA receptors are not only expressed in the nervous system, but also in the pancreas, spleen, lungs, and even hematopoietic progenitors. This provides new insights into the relationship between the nervous system and the hematopoietic system.

Summary: A novel leaf detection scheme was proposed to accurately determine leaf shapes in natural scenes, showing comparable detection ability to Faster R-CNN. The method achieved detection accuracy ranging from 81.10% to 100% and demonstrated stable performance in determining leaf direction and shape measurement for various plant images.

Summary: Catalytic pyrolysis of biomass over CeO2 to prepare ketonic chemicals is an important way to achieve carbon emission reduction, but the role of catalyst structure has been overlooked. In this study, nano-CeO2 with different crystal shapes were synthesized and tested in the catalytic ketonization of xylan. Results showed that C-CeO2 produced the highest yield of ketones. Characterization results revealed that C-CeO2 had the lowest content of oxygen vacancies and the highest proportion of {100} facets, which contributed to the total yield of ketones.

Summary: This study reveals that the CpDll gene regulates the formation of deeply lobed leaves in zucchini, and sequence variation in its promoter region is associated with leaf shape. The findings provide new insights into the molecular basis of leaf lobe formation in pumpkin/squash and other cucurbit crops, and facilitate marker-assisted selection in zucchini breeding.

Summary: Leaf morphology is an important trait for plant architecture and stress resistance. In this study, a rice mutant, ltr1, with rumpled leaves and decreased grain yield was identified. LTR1, a wax synthesis gene, was found to be constitutively expressed in various tissues, with higher expression in leaves and panicles. Overexpression of LTR1 increased grain yield and positively regulated salt stress by affecting water and ion homeostasis. These findings provide insights into the molecular mechanisms of leaf morphogenesis and stress response, and offer a potential strategy for stress-tolerance breeding.

Summary: The study by Bossart et al. discusses the in vivo receptor occupancy, body weight lowering effects, and first-in-human results of SAR441255, a triagonist targeting GLP-1R/GIPR/GcgR. The results show positive acute glucoregulatory effects and acceptable safety profile in terms of gastrointestinal tolerability and cardiovascular hemodynamics.

Summary: This study identified a transcription factor, StDL1, that regulates dissected leaf formation in potato. Knockout of StDL1 changes the leaf morphology from dissected to non-dissected. The genotype frequency of Stdl1/Stdl1 has increased significantly in cultivated potatoes.

Summary: Plants have evolved various strategies to adapt to their environment, with control of body structure and phase change timing being important processes. Phase changes in plants are responses to environmental and endogenous signals, involving alterations in plant morphology, physiology, and gene regulatory networks. Six main pathways interacting with environmental and endogenous cues regulate plant phase transitions, with sugar also playing a role in phase change and branching control. Recent advances in understanding genetic and molecular mechanisms in plant biology have shed light on how plants regulate phase transitions in response to their environment.

Summary: This article introduces a new mathematical parameter called signed morphomigrational angle (sMM angle), which links cell geometry with the translocation of cell centroid, treating them as one morphomigrational behavior. By combining the sMM angle with other quantitative parameters, the researchers were able to develop a tool called morphomigrational description, which assigns numerical values to various cellular behaviors.
