Summary: The quality of pollen in male date palm genotypes is influenced by the flowering stage and storage conditions. Pollen collected from spathes at the middle of flowering stage exhibited the best viability and germinability. The quality of stored pollen decreased over time, with the least reduction observed at -30 degrees C or 4 degrees C. Different genotypes showed varying levels of pollen quality.

Summary: The study compared protein and amino acid content of porate pollen from male flowers and inaperturate pollen from functionally female flowers of two functionally dioecious Australian species. It found that porate pollen grains from staminate flowers had higher levels of proteins and amino acids compared to inaperturate pollen grains from functionally female flowers. Additionally, the andromonoecious species showed the highest levels of proteins and amino acids in pollen from bisexual and staminate flowers.

Summary: Aldrovanda vesiculosa is a rare aquatic carnivorous plant with limited seed set despite prolific flowering. The structure of its pollen suggests adaptations to aquatic environments, while delays in pollen development stages and altered sperm cell formation may contribute to its low reproductive capability.

Summary: The synstigma is a rare floral structure found in approximately 500 out of about 750 Ficus species, associated with fig-fig wasp pollinating mutualism. It allows for pollen grains to emit pollen tubes that can grow laterally and fertilize surrounding flowers, ensuring seed production by flowers not exploited by fig wasps.

Summary: This study reveals that male-male interference during pollen dispersal can significantly limit plant-siring success by affecting pollen pickup, transport, and deposition. Competitive pollinaria on bees reduce pickup of additional pollinaria, double the overall proportion of lost donor pollen, and decrease total pollen export. Interference specifically increases loss of donor pollen between flower visits and variation in deposition among trials, potentially reducing pollen contact with stigmas and pollen deposition.

Summary: Orchids, known for their beauty, are highly valued as cut flowers and potted plants in the global market. A study on the Cymbidium pendulum orchid revealed the rapid progression of senescence events triggered by pollination, as well as the detailed reproductive development after pollination, providing valuable information for academics and breeders.

Summary: This study found that invasive goldenrods did not suffer from pollinator shortage and ineffective pollination, especially in habitats densely covered by the invader, due to the presence of large-bodied pollinators, which affected the composition of pollinators and pollination effectiveness.

Summary: This study investigated the impact of floral shape on pollination performance using a functionally specialized pollination system. The results showed that open flowers with a specific shape had higher male pollination performance, while female pollination performance was not affected by floral shape.

Summary: The study found that stamen dimetrism appeared multiple times in evolutionary history and is correlated with floral size, with lineages dependent on pollinators evolving the highest stamen dimetrism. The evolutionary lability of stamen dimetrism has likely contributed to maintaining the buzz pollination adaptive plateau in pollen flowers.

Summary: In Valeriana wallichii, female plants receive less pollinator service compared to hermaphrodite plants. Reduced floral size in females offers more stigmas to get pollinated in a single visit.

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: This study investigated the nutrient analysis and species diversity of alpine grasslands in Kashmir Himalaya. The findings showed that soil pH and available macro-nutrients decreased with increasing altitude, precipitation, and decreasing temperature. The study reported a total of 66 plant species predominantly from the Asteraceae, Rosaceae, and Plantaginaceae families. The results also showed relatively low dissimilarity among the studied alpine sites and variability in plant phenophases under different environmental conditions and altitudinal gradients.

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 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: 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.
