Summary: The stamen, as the male reproductive organ of flowering plants, is crucial for plant lifecycle. MYC transcription factors, belonging to the bHLH IIIE subgroup, play important roles in various plant processes. Recent studies have revealed the active involvement of MYC transcription factors in stamen development and their critical impact on plant fertility.

Summary: Overexpression of JcSEP3 in Jatropha curcas leads to defective stamen development, potentially involving brassinosteroid and gibberellin signaling pathways. Transcriptome analysis reveals upregulated genes related to anther and pollen development, as well as genes induced in the brassinosteroid and gibberellin signaling pathways in JcSEP3-overexpressing plants.

Summary: This study reveals how brassinosteroids (BRs) regulate cytoskeletal dynamics to coordinate the proper development of reproductive organs in plants. By studying Arabidopsis thaliana mutants, it was found that mutants unable to sever microtubules showed differential elongation of floral organs, specifically stamen filaments.

Summary: Anther development affects the reproduction of flowering plants. Halophyte Elaeagnus angustifolia can bear fruits in saline soils due to efficient anther dehiscence, while no fruits are produced in non-saline soils. The differential gene expression related to phytohormone, cell wall formation, transcription factors and ion transport may contribute to the differences in anther development under different growing conditions.

Summary: The present study analyzed the expression patterns of MYB transcription factors during anther dehiscence in lily and identified LoMYB21, a transcription factor related to JA signal transduction. Silencing LoMYB21 delayed anther dehiscence and reduced JA accumulation, indicating that LoMYB21 regulates anther dehiscence through the JA synthesis pathway. This study provides a theoretical basis for creating lilies without pollen contamination in the future.

Summary: The Glycoside hydrolase family 9 (GH9) plays a crucial role in cellulose synthesis and hydrolysis in plants. In this study, the researchers investigated the phenotypic characteristics and gene expression of GH9 genes in relation to pollen fertility conversion and anther dehiscence. They identified 74 wheat GH9 genes and classified them into different classes. They found that hormone-responsive elements and light-responsive elements were abundant in these genes, suggesting their involvement in anther development regulation. Based on their findings, they proposed a hypothesis model to explain the regulation pathway of GH9 in fertility conversion and anther dehiscence. This study provides valuable insights into the male sterility mechanism of wheat and offers resources to improve wheat hybrid breeding.

Summary: The study focused on the reproductive biology of Kersting's groundnut, describing the reproductive organs, phenology, and assessing pollen viability and germination. Significant differences were found among morphotypes in terms of reproductive characteristics, with the morphotype ZHLA-2 showing the highest reproductive vigour. This study provides valuable information for breeders to optimize hybridization protocols.

Summary: Auxin plays an essential role during barley pollen maturation by boosting the expression of genes involved in energy production pathways and promoting starch accumulation. This finding suggests that auxin can drive plant cell development by modulating central carbon metabolism, leading to growth and differentiation.

Summary: Short-term heat stress around anthesis in maize has a negative impact on yield, with post-anthesis period being more sensitive. Short-term heat stress reduces pollen shedding and viability, affecting yield.

Summary: Based on our study of 16 Melastomataceae species, we found that stamen heteromorphism in pollen flowers is associated with functional and morphological differences at the pollen grain level. Pollinating anthers are larger and produce more and higher-quality pollen grains, while the feeding anthers are smaller. In addition, there are differences in pollen exine ornamentation in some species. Overall, our findings support the division of labour hypothesis.

Summary: In this study, the essential role of FKBP42, TWISTED DWARF1 (TWD1) in the regulation of stamen elongation through ABCB-mediated auxin transport is demonstrated. TWD1 promotes stamen elongation, anther dehiscence, and pollen maturation, and is required for seed development. ABCB1 and ABCB19 appear to have different functions during different stages of stamen development.

Summary: Decreased spikelet fertility in rice under high temperature is mainly caused by reduced pollen viability and anther dehiscence, leading to abnormalities in pollen and anther development. Heat-susceptible varieties are more affected by these disturbances compared to heat-tolerant varieties.

Summary: Anther development and dehiscence are critical for fertilisation of angiosperm flowers and are highly conserved across different plant families. Understanding the evolution and divergence of anther development between monocots and dicots can lead to greater insights into the male reproductive process and increased crop yields. There is a need to study the complexities of anther development and challenge established models to achieve future sustainable crop yields.

Summary: The study found that shading stress decreased the fertilization rate of rice spikelets, thereby affecting yield, primarily by affecting key pollination and fertilization processes such as pollen germination and pollen release.
