Summary: This review briefly describes the different flowering processes in perennial trees and summarizes the recent advances in understanding how woody plants regulate flowering through dynamic gene expression. The florigen gene FT and its antagonistic gene TFL1 play a central role in flowering transition events, and flower development requires interactions between floral homeotic genes and AGL6.

Summary: CsDFB1 functions as a transcriptional regulator of local auxin distribution in cucumber, impacting floral organogenesis and vascular differentiation. It interacts with CsPHB to regulate the expression of genes involved in auxin biosynthesis and transport, thereby playing a pivotal role in auxin distribution. This CsDFB1-CsPHB module represents a regulatory pathway governing floral development and vascular patterning in cucumber.

Summary: The floral morphology of Eriocaulon is highly diverse due to fusion, reduction, or loss of perianth parts. Nectariferous carpellodes originated first in staminate flowers, while petal glands and nectariferous branches in pistillate flowers originated independently through the transfer of function.

Summary: This study aims to understand the floral development and identify the ontogenetic pathways that lead to organ variation and andromonoecy in Mimosa species. The research reveals that the development of floral organs in Mimosa is synchronous but differs in the order of appearance. The merism variation in Mimosa is mainly due to the absence of organs in the perianth and androecium. The findings contribute to a better understanding of floral evolution and unstable organ merism in the mimosoid clade.

Summary: In this work, a label-free scattering-based method combined with deep learning is proposed to segment lipid droplets in Caenorhabditis elegans. By using asymmetric illumination and high-resolution dark field microscopy, the method achieves accurate segmentation of lipid droplets, outperforming standard methods.

Summary: The floral anatomy and development of species within the Xyris genus were compared to investigate gynoecium evolution. It was found that axile placentation may be the ancestral condition, with parietal and free-central placentation derived from it. Basal placentation evolved independently multiple times within section Nematopus. The study suggests a need for a revised infrageneric classification due to uncertainties in the phylogenetic position of certain species.

Summary: This paper proposes a reflective quantitative phase-contrast microscopy based on annular epi-illumination of light-emitting diodes, which enables high-resolution imaging. By phase-retarding the unscattered wave from the sample, finer structures or three-dimensional tomography of reflective samples can be obtained, making it significant for imaging of industrial devices and biomedical dynamics.

Summary: In this paper, an unsupervised low-light enhancement network using context-guided illumination-adaptive norm (CIN) is proposed. The network consists of two stages: the first stage uses a pixel amplifier module (PAM) to generate a coarse estimate, improving visibility and aesthetic quality, while the second stage enhances the image using CIN. A region-adaptive single input multiple output (SIMO) model is also introduced to generate multiple enhanced images for users to choose from. The experimental results show that the proposed model outperforms previous methods quantitatively and qualitatively.

Summary: This study introduces a light sheet-based structured light illumination light field microscopy system for fast 3D imaging, utilizing a digital micromirror device to generate sinusoidal patterns rapidly. By combining deconvolution and HiLo algorithms, fast volumetric imaging with improved optical cross-sectioning capability is achieved. Imaging experiments on various samples show that this new method presents a fast 3D imaging solution with significantly enhanced optical cross-sectioning capability compared to standard light sheet-based LFM.

Summary: By miniaturizing spiral phase plates and integrating them with structural colour filters, we have successfully generated coloured orbital angular momentum beams using incoherent white light. These beams, which possess both spatial and temporal coherence, can independently generate multiple helical eigenstates and combine colour information into orbital angular momentum beams.

Summary: In this study, we explore the use of classical correlated multi-mode Gaussian light for quantum illumination. It is found that retaining the idler modes in addition to illuminating the target with the signal can provide performance gain. Examples show that multi-mode Gaussian classical correlated states with high correlation between the sent and idler modes outperform two-mode Gaussian states with entanglement between the sent and idler mode.

Summary: The study of the inflorescence, floral structure, and ontogeny of the Chinese ashes provides insights into its unique floral structure and developmental basis, compared to the Sapindaceae family. The research reveals significant floral dimorphism in terms of differences in filament and style lengths, as well as the presence or absence of fruits. Additionally, the presence of empty stamen positions is inversely correlated with the sequence of petal initiation and delayed growth, suggesting a balance between petal and stamen initiation.

Summary: This review focuses on the photocatalytic technologies and materials of polymeric photocatalysts for the oxygen evolution reaction (OER). Two practical systems, namely particle suspension and film-based photoelectrochemical systems, are discussed. The concept is reviewed in terms of thermodynamics and kinetics, and the key characteristics of polymeric photocatalysts, such as light absorption, charge separation and transfer, and surface oxidation reactions, are examined. Satisfactory OER performance by polymeric photocatalysts could lead to cost-effective, sustainable, and renewable water splitting and other advanced applications using solar energy.

Summary: The maple genus, one of the largest tree genera in the Northern Hemisphere, exhibits high morphological and molecular variability, leading to infra-specific complexity. A study in Iran aimed to clarify the intraspecific situation of Acer cappadocicum Gled. using macro-/micromorphological and molecular approaches. Results showed no correlation between variations in leaf morphology, ISSRs, and ITS, with differentiation and variability in the ITS region within this species.

Summary: The study shows that size-matching between plants and pollinators significantly affects foraging efficiency and pollination efficiency in their interactions. A size-matching index is suggested as a reliable metric for predicting interaction frequency and visit effectiveness in terms of foraging and pollination efficiency.

Summary: Environmental gradients play a significant role in shaping the genetic diversity and differentiation of Circaea lutetiana populations in the Hyrcanian forests. The genetic structure is more influenced by environmental factors rather than geographic distance. Gene flow does not explain the spatial patterns of genetic structure, suggesting that environmental adaptation is the main driver of genetic structuring in these populations.

Summary: The evolution of bilabiate flowers in Lamiaceae often leads to a reduction in stamen number, which is associated with decreased pollen production. Bistaminate flowers exhibit lower pollen numbers compared to tetrastaminate flowers, but show a higher selfing rate and structural adaptations for delayed selfing. Adaptive mechanisms, such as increasing pollen transfer precision and evolution of delayed selfing, are closely linked with stamen reduction in bistaminate Lamiaceae.

Summary: The study examined the macro/micro-morphology of nutlets in 11 species of the Boraginaceae family to evaluate taxonomic relevance. It found that the nutlet ultrastructure pattern in Rochelieae is informative at the genus level but not at the species level. Additionally, the study demonstrated that the presence of glochids is not an ancestral trait and evolved in the genus Lappula. The boundary of nutlet microstructures between L. barbata and L. microcarpa was also discussed.

Summary: The analysis of phenolic acid compounds in 12 species of Dipsacoideae revealed caffeic acid and cinnamic acid as potential chemotaxonomic markers. Additionally, the study identified Scabiosa koelzii Rech. and S.amoena Jacq. as distinct groups based on their phenolic acid profiles. This suggests that phenolic contents could be used as significant markers in the chemotaxonomy of Dipsacoideae.
