Summary: Leaf numbers are crucial for estimating crop yield. Traditional manual counting methods are laborious and costly. Existing methods for counting leaves in rosette plants show promising results, but there is a lack of effective solutions for monocot plants. We propose a deep neural network-based method that achieves superior performance even with severe leaf occlusions. Our method extracts leaf skeletons and applies augmentation to enhance structural variety, resulting in improved accuracy and lower training cost compared to existing approaches.

Summary: The study investigated the leaf traits of alpine and foothill ecotypes of Arabidopsis arenosa and found significant differences in many traits, which may be plastic adjustments to the local environment rather than geographical origins.

Summary: This study employed plant anatomy techniques to investigate leaf morphology variation in Dyckia species, with a focus on establishing characters to delimit the Dyckia selloa complex. Results identified important morphological and anatomical characters, such as spine color, water-storage parenchyma, mechanical hypodermis, and tetracytic stomata. The findings support the current delimitation of the complex and recommend further investigation of reproductive and/or vegetative organs to better understand the relationships among Dyckia species.

Summary: Our study suggests that species in hot and seasonal savannas can have different strategies to deal with drought, which can be equally successful in maintaining a favorable water balance for species persistence and coexistence. Understanding the relationships between anatomical and hydraulic traits is crucial for accurately modeling transitions in trait states between different vegetation in the Amazon region.

Summary: Many arid lands are experiencing more frequent and extreme droughts due to climate change, and conservation of water is necessary for urban landscape irrigation. This research investigates the effects of substrate water availability on the growth and development of Shepherdia xutahensis, a drought-tolerant plant. The study found that the plant adapts to drought through various mechanisms, including reducing leaf temperature and limiting water loss.

Summary: The study found that Yucca gloriosa may use both C-3 and CAM pathways, with varying degrees of CAM upregulation under drought stress among different genotypes. While correlations exist between leaf anatomy and physiology across all three Yucca species, these correlations break down at the species level in Y. gloriosa.

Summary: This study investigated the effects of leaf anatomical traits and environmental stimuli on the photosynthesis of rice plants. It found that the response of mesophyll conductance to temperature was stronger at the mid-tillering stage and with high nitrogen treatment, which could be attributed to a higher activation energy of the membrane.

Summary: Research on succulent leaves has focused on defining succulence, understanding its evolutionary trajectory and ecological implications, but there is still limited understanding of the molecular regulation of leaf succulence. Studies show that regulation of cell size, determination of vascular patterning, and water transport between cells have direct implications for understanding leaf succulence. Connecting functional genomics of leaf patterning with knowledge of the evolution and ecology of succulent species will guide future research on leaf succulence determination and maintenance.

Summary: The present investigation revealed that the infection of papaya leaves by PaLCuV resulted in significant changes in the anatomy, physiology, and pharmacological properties of the leaves. The infected leaves showed reduced stomatal density, photosynthesis rate, and enzymatic activity, while the size of guard cells, transpiration rate, and anthocyanin content increased. Moreover, the pharmacological potential of the infected leaves was significantly decreased.

Summary: By analyzing 31 floating-leaved species, it was found that there is a similar allometric relationship between leaf area and petiole transverse area, as well as between total stomatal area and petiole vascular area, compared to terrestrial plants. However, the slope of the relationship between stomatal and xylem area in floating-leaved plants is smaller, indicating a lower selection pressure on stomata in terms of water transport. After considering phylogeny, the scaling relationships between leaf construction and petiole traits in floating-leaved plants remained significant.

Summary: This study focuses on the evolution of placentation in flowering plants and finds that axile placentation is the most common and marginal placentation is the most primitive. Placentation types show strong association with ovule number. The results provide new insights into the evolution of placentation.

Summary: The study found that Trianthema portulacastrum is the second genus of vascular land plants in which C-4 and features of CAM co-occur, and the first C-4 plant with CAM-type acidification described for the Aizoaceae. This suggests that small herbaceous plants with mildly succulent leaves and fleshy stems may be a significant component of CAM biodiversity.

Summary: The herbaceous plant Trianthema portulacastrum exhibits features of crassulacean acid metabolism (CAM), including low-level nocturnal acidification in the leaves and stems. Despite only showing net CO2 uptake during the day, the plant displays curved kinetics of reduced CO2 loss during the night consistent with CAM. This discovery highlights the potential biodiversity of CAM in small herbs with succulent leaves and fleshy stems.

Summary: Fernseea is an endemic genus of Bromeliaceae in the Atlantic rainforest, with only two species, one endangered and one critically endangered. This study provides a taxonomic overview of Fernseea, including morphological descriptions and leaf anatomy, comments on taxonomy, biogeography, and conservation status, as well as a key for species identification. A neotype for F. itatiaiae is designated, and a new form, F. bocainensis forma brevifolia, is described.
