Summary: Climate change can directly and indirectly affect plant reproductive success through disruptions in animal pollination. Plants have evolved reproductive strategies to overcome limitations in pollen and water availability, and climate change may cause plants to become more pollen limited in wetter seasons. In this study, two perennial species showed different reproductive responses to future climate conditions, with one species producing more seeds when given supplemental pollen. The findings highlight the potential for changes in pollinator services to impact plant reproduction in a changing climate.

Summary: Mechanical pollination is crucial for the production of fruit and nut crops, but faces challenges due to knowledge gaps and access to proprietary information.

Summary: GPI-APs play important roles in the interactions between pollen/pollen tube and pistil tissues, affecting pollen germination on the stigma, pollen tube growth in the transmitting tract, pollen tube guidance to the ovule, and pollen tube reception in the embryo sac.

Summary: The study found that Oenothera drummondii exhibits differences in fruit and seed characteristics between native and non-native populations, with high self-compatibility and a mixed reproductive system. The Integral Reproductive Success Index (IRSI) showed variations in fruit set, seed set, and germination, indicating differences between populations.

Summary: Salinity is a significant problem for salt-sensitive chickpea, and understanding the molecular mechanisms under salt stress is essential. Transcriptomic analysis of two genotypes revealed differentially expressed genes associated with salt tolerance, including genes involved in flowering time, pollen development, and transcription regulation. These genes can be potential candidates for improving salt tolerance in chickpea.

Summary: Hybridisation between different species can result in maladapted or nonviable offspring due to genetic incompatibilities. Mating with close relatives or self-fertilisation can lead to inbreeding depression. Therefore, organisms need to carefully choose their mating partners to avoid both of these problems. In plants, pollen-pistil interactions play a crucial role in avoiding inbreeding and hybridisation with other species. This review focuses on the mechanisms of pollen-pistil interactions and their importance in maintaining species integrity.

Summary: Pollen-pistil interactions act as important prezygotic reproductive barriers in plants, playing a critical role in mate selection by rejecting heterospecific pollen and interacting with self-incompatibility systems. These interactions can involve active pollen rejection systems, mechanisms linked to cell wall-modifying enzymes, and differential attraction and inhibition of sperm cell release as barriers to heterospecific pollen tubes.

Summary: Self-incompatibility (SI) in flowering plants is a genetic system that prevents self-fertilization. In pear, incompatible pollen tubes show swelling at their tips, which is mediated by acetylation of the soluble inorganic pyrophosphatase (PPA) PbrPPA5. Acetylated PbrPPA5 accumulates in the nucleus and forms a transcriptional repression complex with the transcription factor PbrbZIP77 to inhibit the expression of the PME gene PbrPME44.

Summary: Nouelia insignis, a rare and endangered tree species, shows high flowering synchrony and stable flowering duration in its natural population. Pollination requires pollinators, with insect activities playing a crucial role. Despite the low number and frequency of pollinators, reproductive fitness is not limited. Seed setting rate is influenced by changes in flowering phenology between years, with higher seed set in early flowering years.

Summary: This study investigates the reproductive isolation between different species of Cucumis, including cultivated melon. It identifies several barriers to hybridization, such as pollen tube arrest, fruit set failure, and hybrid male sterility. The study also finds a significant correlation between genetic distance and reproductive isolation stages.

Summary: The study found seasonality in HPD, with greater diversity and frequency of heterospecific pollen on stigmas of species flowering in the dry season compared to the rainy season. Stigmas of ecologically generalized species had more heterospecific pollen, while the relationship for ecologically specialized species depended on floral phenotype.

Summary: In recent years, there has been a significant renewal of apricot cultivars worldwide, with the introduction of many new varieties. This study focused on determining the pollination requirements of a group of new apricot cultivars by molecular identification of S-alleles. The results provide valuable information for apricot breeding programs, orchard design, and addressing fruit set issues in established orchards. The diversity observed at the S-locus suggests a possible genetic bottleneck in the breeding programs.

Summary: Most terrestrial angiosperms form mutualistic relationships with mycorrhizal fungi and animal pollinators, but the effects of mycorrhizae on pollinator behavior and plant reproduction are not well understood. This study examined the effects of inoculating highbush blueberry plants with ericoid mycorrhizal fungi on flowering investment and attractiveness to pollinators. The results showed that plants treated with inoculums were more likely to flower and produced more inflorescence buds than non-inoculated plants.

Summary: The study evaluated the progamic phase of fertilization and fruit set in four European plum cultivars in Western Norway, showing different adaptability of both recipient and donor cultivars to specific ecological conditions. The pollinizers Victoria, Opal and C. Lepotica were proven to be very good pollinizers for certain cultivars, while cultivars Opal, R. E. Prolific and Mallard were considered excellent pollinizers for Edda under certain temperature conditions.

Summary: Narrowly endemic species are vulnerable to catastrophic events and less capable of adapting to environmental pressures. However, traits like preferential outcrossing and high fecundity can maintain genetic diversity and boost resilience. This study on the endangered Grevillea bedggoodiana found it to have preferential outcrossing and high genetic diversity, indicating reproductive health and genetic resilience.
