Summary: Similar to other orchid species, Paphiopedilum hirsutissimum relies on mycorrhizal fungi for seed germination and seedling development. This study identified a specific strain of endophytic fungus that supports the advanced developmental stage of P. hirsutissimum seedlings. The findings have ecological value and may contribute to the protection and reintroduction of endangered orchid species.

Summary: The article discusses the endangered status of orchids in the plant kingdom and proposes a new reintroduction method for orchids by co-sowing orchid seeds directly with orchid mycorrhizal fungi carrying ecological specificity. This innovative approach aims to reconstruct long-term and self-sustained orchid populations, representing a potential benefit for the reintroduction of endangered orchids in nature.

Summary: This study investigated the effects of daily temperature fluctuations on seed germination and development in Dracula felix, a native epiphytic orchid from the neotropics. The results showed that seed viability decreased from 60% to 37.78% and 0% after 8 and 16 weeks, respectively, under 22±2℃. Seed viability was completely lost when seeds were stored at -10℃ in the dark. Less than 50% germination was observed across all treatments, but significant improvement in germination was found at 17/22℃ compared to constant temperature treatments. Early seedling development stages were only observed under specific temperature and light conditions. None of the tested fungal strains improved germination or seedling development. This information is critical for the ex-situ conservation of this and other rare Dracula species under current and future climate change scenarios.

Summary: The transition from seed to seedling is a crucial stage in the life cycle of plants, involving tissue hydration, mobilization of nutrients, and activation of metabolic activity in seeds. This process requires extensive reprogramming of genetic, epigenetic, and hormonal switches, leading to the activation of vegetative growth genes and silencing of seed maturation genes.

Summary: Stanhopea tigrina, an endemic orchid from Mexico, is currently endangered. This study successfully established an in vitro propagation system using organic extracts and growth regulators to stimulate plant growth. The results show that symbiotic acclimatization with fungi can be an effective method for the regeneration and mass propagation of this threatened orchid species.

Summary: Mycorrhizal fungi play a crucial role in seed germination and seedling development of Paphiopedilum barbigerum, with Epulorhiza sp. FQXY019 showing significant promotion in seed germination and seedling growth. Inoculation with FQXY019 leads to progression from seed germination to rooting stage, with different effects observed in different culture media.

Summary: Since the early 1930s, innovations in the agriculture industry have had a significant impact on meeting the growing demands for food. Seed technology research, in particular, has contributed to improving crop performance. Ultrasonic treatment of seeds is a green technology that shows potential for enhancing germination and seedling development by stimulating water and oxygen uptake and seed metabolism.

Summary: This study developed an easy-to-use solution by isolating fungi and using fungus-seed bags to promote protocorm formation and seedling development in D. officinale, providing an effective method for restoration-friendly cultivation of this critically endangered orchid. The fungus-seed bags showed advantages such as low-cost mass production, convenience in transportation, and environmentally-friendly materials, making it a universal application for conservation translocations of epiphytic orchids based on symbiotic seeds germination.

Summary: The transition from seed to seedling is a crucial step in the plant life cycle. In this study, the authors investigated the changes in water and oxidative status, as well as gene expression, during this transition in Pisum sativum seeds. They found that the accumulation of ROS and the shift in water and oxidative status were correlated with the loss of desiccation tolerance. RNA sequencing analysis revealed differentially expressed genes related to metabolism, photosynthesis, cell wall biosynthesis, redox status, and stress responses. The findings suggest that specific genes, such as LTI65, LTP4, and HVA22E, may play a crucial role in the desiccation tolerance loss during the transition.

Summary: AtC3H59, a non-TZF protein in Arabidopsis, plays pleiotropic roles in seed germination, seedling development, and seed development, interacting with Desi1 in the nucleus via its WD40 domain. This study provides the first description of the biological functions of the ZFWD protein and Desi1 in Arabidopsis.

Summary: The study found a positive relationship between species abundances and range size on tropical islands, which is influenced by endemism and land-use. Many endemics with smaller range sizes are globally threatened, but higher abundances may buffer them from extinction risks.

Summary: This study evaluated leaf damage on seedlings in four subtropical forests, finding that taller seedlings experienced higher herbivore damage. Herbivory increased at higher elevations and in areas with higher light availability in one forest, but not in the other three. The results suggest that plant apparency may be the most important predictor of leaf damage in the seedling communities of subtropical forests.

Summary: This study investigated the impact of elevation and abiotic factors on the regenerative capacity and community characteristics of the soil seed bank (SSB). The results showed that increasing elevation and canopy openness led to lower species richness and diversity, but higher SSB abundance; steeper slopes resulted in decreased abundance and richness, possibly through indirect pathways involving soil pH and nutrients.

Summary: In this study, we evaluated the suitability of three seed viability tests for orchid seeds and found that lifeform and sterilization of seeds are important influential factors in seed viability testing. The Evans blue test was found to be the most reliable method, regardless of seed sterilization and storage time. Therefore, we recommend using the Evans blue test for seed viability assessment in orchids.

Summary: The study revealed that hemiepiphytic Ficus species are better adapted to drier and warmer conditions, showing higher germination and seedling survival rates. In contrast, non-hemiepipytic species had higher germination rates under greater water stress. Hemiepiphytic Ficus species germinated more readily at higher relative humidity levels.
