Summary: Hazelnuts have gained attention in the confectionary industry, but sourced cultivars struggle to survive in new climates. Indoleamines, such as serotonin, have been found to help plants adapt to stress. In this study, the effect of indoleamines on flowering response in hazelnut cultivars was examined. The sourced cultivars responded well to serotonin treatment, producing more flowers. Local hazelnut cultivars had higher levels of indoleamines, providing better adaptation to stress. This study suggests indoleamines could be used to assess cultivars for stress adaptation traits.

Summary: The timing of flowering and fruiting is crucial for the reproduction, population size, and range of fruit-eating animals. A regression analysis was conducted to understand the impact of climate on the timing and availability of fruits for the endangered Hainan gibbon in China. Significant seasonal and inter-annual variations were observed in the reproductive phenology of fruiting species, with severe food scarcity for the gibbons between January and April. Sunshine affected flowering time, while temperature influenced fruiting phenology. The restoration of gibbon habitat should include planting fruit trees that bear fruit during the low food availability period from January to April.

Summary: The conversion of natural landscapes to agriculture is a major cause of biodiversity loss worldwide, and wild plants in heavily modified landscapes are responding to this landscape change. In this study, the effect of increasing agricultural landscape modification on defensive and reproductive traits in three commonly occurring Brassicaceae species was tested. The results showed that plants from agriculturally dominant landscapes had reduced flower size and herbivore leaf consumption, and one species also exhibited reduced fitness associated with increasing agricultural landscapes. These findings suggest that the conversion of natural landscapes to agriculture has consequences for wild plant evolution.

Summary: Cerberiopsis candelabra Vieill. is a long-lived rain-forest tree species with episodic establishment and recruitment gap possibly indicating population decline. Tree age structures show a long interval between establishment and recruitment, with high seedling mortality. Large-scale exogenous disturbances or high densities of flowering trees may be crucial for in-situ regeneration.

Summary: Organisms from higher trophic levels can indirectly mediate competitive interactions between plant species, but the presence of a third plant species and the size and competitive ability of the target plants can influence such interactions. In this study, we conducted an outdoor experiment using four aquatic plant species with similar niches but differing greatly in size. The results showed that the presence of a third plant species can regulate plant-plant interactions, but this effect depends on the size and competitive ability of the competing species as well as the third species. These findings highlight the role of complexity in plant-plant interactions and have implications for species coexistence and biodiversity maintenance.

Summary: A decade of genetic association studies has shown that complex traits are determined by multiple genetic loci, each with a small effect-size. This study used a multilocus approach to estimate the degree of polygenicity in fitness-related traits of a long-lived plant, maritime pine, and analyzed its variation across environments and years. The results showed a remarkably stable degree of polygenicity across traits, environments, and years, with evidence of local adaptation and negative selection.

Summary: TEOSINTE BRANCHED1/CYCLOIDEA/PROLIFERATING CELL FACTOR (TCP) transcription factors play multiple roles in plant growth and development. They have been found to be involved in reproductive development and the diversification of flower form in various species. Furthermore, TCPs from other clades have been shown to be important for processes such as flowering time regulation, inflorescence stem growth, and proper development of flower organs. This review summarizes the different roles of TCP family members in plant reproductive development and the molecular networks involved.

Summary: Polyploidy is an important phenomenon in the evolution and breeding of fruit crops, and has the potential to improve yield, fruit quality, and adaptation to adverse conditions. This study induced polyploidy in three wild blackberry species and found that the polyploid plants showed better performance in terms of morphological, physiological, and phytohormonal traits. However, they had fewer viable pollen grains compared to the diploid plants.

Summary: Plants protect themselves from stresses by emitting volatile terpenes, which are also important constituents in the atmosphere. This study investigated the relationship between leaf terpene contents and terpene emissions in Japanese cedar. The results showed that the emissions of monoterpenes were correlated with their leaf contents, while variations in emissions of individual terpenes did not correspond to variations in concentrations in leaves. Diterpenes were emitted when they were present in trees, indicating a linkage between emissions and storage pools. However, the algorithm used in this study could not explain the emissions of diterpenes due to their low vapor pressure.

Summary: The study examines the variation in leaf and whole-tree traits of Japanese cedar trees with different geographical variations, demonstrating that whole-tree properties play a key role in regulating the growth characteristics of adult trees, rather than leaf properties. The research also finds that organ-level resource use strategies are coupled with each other, and the hydraulic architecture at the whole-tree level is linked to leaf distribution and water transport capacity, leading to differences in growth characteristics among different geographic origins.
