Summary: Information on reproductive biology and pollination ecology studies of threatened plants are essential for sustainable utilization and effective conservation strategies. In this study, reproductive behavior and pollination mechanisms of Rheum webbianum, a vulnerable medicinal herb, were investigated. The species exhibits unique reproductive events and cold survival strategies. The flowers have temporally separated male and female phases, and the stigma lobes move upward after anthesis, facilitating outcrossing. The species is self-compatible and cross-fertile based on pollen/ovule ratio estimates and pollination experiments.

Summary: This study investigated the agro-morphological traits and genetic differences in 19 populations of Mentha longifolia. The results showed a high degree of morphological and genetic variation among populations, with higher genetic diversity among populations than within populations. This is attributed to low gene flow and greater habitat variability.

Summary: Epigenetics refers to heritable changes in gene expression patterns without altering the DNA sequence. These changes are induced by DNA methylation, histone modification, and RNA-mediated mechanisms, and play a dynamic role in plant development, adaptation to environmental changes, and reproduction.

Summary: This study discusses the impact of climate change on the habitat distribution of the endangered medicinal herb Valeriana wallichii. The results show that its suitable habitats will significantly decrease under future climate scenarios, and the niche dynamics will also be affected. The habitats of Valeriana wallichii are highly vulnerable to climate shifts, highlighting the importance of this study for species conservation and recovery efforts.

Summary: This study investigated the ambophily in Olea ferruginea and found that it is primarily wind-pollinated but also attracts insect pollinators. The floral structure of O. ferruginea allows for both wind and insect pollination. The study provides insight into the ecological and evolutionary adaptations and consequences of spatio-temporal variation in plant-pollinator interactions.

Summary: In the era of anthropocene, global warming is impacting the distribution of plant species, especially those that are endemic, inhabit higher elevations, and have narrow ranges. The current study used BIOMOD ensemble forecasting to predict the potential distribution of Dactylorhiza hatagirea and Rheum webbianum in Himalayan biodiversity hotspots under climate change scenarios. Results showed that the suitable habitats for these species will significantly decrease in the future. This study highlights the severe impact of climate change on the habitat distribution of plant species in the Himalayan biodiversity hotspots.

Summary: In this study, species distribution modelling was used to explore the potential distribution of Aconitum heterophyllum under current and future climatic scenarios. The results showed that annual precipitation significantly influenced the distribution of this species. Future climatic modelling predicted a significant decrease in suitable habitats for A. heterophyllum, particularly before 2050.

Summary: Under the constant strain of rising environmental changes, understanding and describing plant microbe interactions in terms of abiotic stress resistance has become crucial. Multi omics approaches provide comprehensive data on plant microbe mechanisms and hormone signaling networks, enabling practical applications for plant survival under extreme conditions. This study explores the interplay between plant growth promoting microorganisms and crop plants, providing insights into overcoming environmental stress through the implementation of omics-based strategies.

Summary: Studies have shown that climate change affects plant phenology, but there is a lack of data for many regions and species, including the Himalayas. This study used real-time field observations and long-term herbarium records to investigate changes in the flowering phenology of Olea ferruginea in response to climate change. The results showed that the flowering dates of O. ferruginea have shifted earlier by 15-21 days over the past 100 years, which is significantly correlated with increasing temperatures.

Summary: This study analyzed the relationship between plant species diversity and distribution patterns with elevation, slope, and aspect in the Kashmir Himalayas. It found that lower altitudes, southern aspect, and drier habitats had higher diversity. Altitude was the most important factor influencing species composition, and its interaction with habitat explained the most variation. The study provides a reference for future research on plant distribution and preferences in mountainous regions.

Summary: Olea ferruginea, a widely distributed wild olive species, exhibits andromonoecy with staminate and perfect flowers. This study investigates the differential performance of staminate and perfect flowers in reproductive assurance. Results show higher pollen viability, germination, and pollen tube growth of staminate flowers. The species is self-incompatible and hand cross-pollination improves natural fruit set, especially with pollen from staminate flowers.
