Summary: Autophagy is a mechanism for degrading damaged or unwanted cells and recycling their components. Research on autophagy has expanded from yeast to mammals and plants, and the core machinery regulating autophagy appears to be conserved. In plants, autophagy plays essential roles in responses to stressful conditions and contributes to normal development, particularly in reproduction.

Summary: This paper evaluated the occurrence of hormetic dose responses in pollen reported over the past eight decades, finding a broad generality of this response across different taxa, inducing agents, and endpoints measured. This indicates the need to explore the emerging biological, ecological, agricultural, economic, and public health implications of inducing hormetic dose responses in pollen.

Summary: Zingiber zerumbet adopts clonal propagation and lacks sexual reproduction, while Z. corallinum is sexually active. The inhibition of sexual reproduction in Z. zerumbet occurs at the stage of pollen tube rupture and reception. This inhibition is regulated by the suppression of genes involved in pollen tube integrity and signaling in Z. zerumbet, compared to the activated transcription of these genes in Z. corallinum. These findings provide insights into the regulatory mechanisms of sexual reproduction in these two species.

Summary: This study assessed the pollen fertility and in vitro pollen germination of sorghum male and female lines and F-1 hybrids using multivariate analysis. The findings showed significant genetic divergence in the hybrids and identified genotypes with high pollen fertility for the breeding of high-yielding hybrids. The study also revealed the restoration behavior of pollen fertility in the hybrids, which will facilitate the identification of potential restorers in sorghum breeding programs.

Summary: Regulated or programmed cell death (RCD or PCD) is a fundamental biological principle in multicellular organisms and plays a crucial role in plant reproduction. This article sheds light on the latest research into PCD mechanisms, covering various processes from sex determination to sporogenesis, pollination, and fertilization.

Summary: Most flowering plants have both male and female reproductive organs, with a widespread adaptation to limit self-fertilization known as self-incompatibility (SI). In some flowering plants, different mating types are associated with different floral morphologies. In the heterostylous plant Primula, a specific gene controls style length and determines the mating types. Furthermore, this gene also determines the female incompatibility type. The findings suggest that brassinosteroid (BR) levels in the stigma and style play a role in controlling pollen performance and prevent self-fertilization.

Summary: Sexual reproduction in the Zostera noltei species of seagrasses in the Ria de Aveiro lagoon of Portugal shows similarities in flowering effort and phenology among meadows, with a longer flowering period and high seed production and germination ability compared to other European populations. However, further research is needed to understand the natural recovery capacity of the species.

Summary: Members of the LARP family contain a conserved La module associated with RNA-binding activity. Analysis of the maize gene ZmLARP6c1, specific to pollen, suggests its role in pollen-specific RNA regulation. Mutant plants with an inserted Ds-GFP element in the ZmLARP6c1 gene displayed reduced transmission as males, but not as females, indicating an important regulatory function during male gametophyte development.

Summary: In this study, apple cultivars were categorized based on their pollen tube growth performance, with 41 individuals divided into three subgroups using statistical analysis and a decision tree model for prediction. Thresholds were established from the decision tree to characterize new observations, demonstrating the effectiveness of the methods in a case study with 29 apple accessions.

Summary: Plants have metaCaspases instead of caspases, which play critical roles in programmed cell death during plant development and defense responses. The diversity in the number of metaCaspases in different plant species suggests varying functions due to diverse evolutions.

Summary: Using fluorescence recovery after photobleaching, we observed the occurrence and localization of rapid vesicular activities in the tip region of growing pollen tube. We demonstrated that both vesicle polar exocytic fusion and endocytosis take place at the apex of the pollen tube. Furthermore, we found that the dynamic activities of tip-focused exocytosis and endocytosis are closely correlated with the spatial organization of actin fringe.
