Summary: The surface of pollen grains is strengthened by components produced by tapetum cells, which are regulated by the GASSHO receptor-like kinase pathway. The pathway is controlled by sulfated peptides and requires the action of subtilases. Three types of cells coordinate to deposit pollen wall through molecular dialogue.

Summary: The genes bHLH010 and bHLH089 are essential for pollen wall development and regulate specific transcriptional and metabolic networks. Mutations in these genes lead to defective pollen wall structures and altered accumulation of metabolites related to pollen wall morphogenesis.

Summary: The study investigated the pollen developmental characteristics in Dendrobium officinale by examining polysaccharides and lipids. The anther wall of D. officinale consists of multiple layers of different cells. The microspore mother cells undergo simultaneous microsporogenesis without a callose wall. The pollen tetrads inside the pollinium lack the exine structure, and pollen germination mainly occurs from the pollen grains inside the pollinium.

Summary: Climate change poses a significant threat to plant species, causing shifts in latitudinal and altitudinal distributions globally. The endemic Balkan species, Helen's bee orchid, is expanding east and southwards against expectations, with projections suggesting a future southeastward shift and significant area changes. The species is expected to become extinct in its core distribution but establish a strong presence in higher altitude areas of the Central Peloponnese, indicating adaptation to previous climatic extremes.

Summary: LoMYB33, a homolog of GAMYB in lily, plays an important role in anther development and pollen formation. Its overexpression or silencing can affect normal anther development and result in partial male sterility.

Summary: This study investigated the flowering biology features of winter wheat genotypes and found that anther extrusion capacity has a significant impact on cross-pollination ability. The results also highlight the importance of pollen production and germination potential. This research contributes to improving the pollen dispersal ability in wheat for cross-pollination.

Summary: Short-term exposure to low temperatures can lower pollen viability and germination in strawberry, resulting in fruit malformation. Ultrastructural analysis revealed abnormal development of anther and pollen under low temperature, with deformed epidermal cells and excessive accumulation of starch.

Summary: This study investigates the effects of two pretreatment methods on phytosterol analysis and identifies high contents of phytosterols in tree peony pollen and anther wall. The study also discusses the impact of wall breaking and different developmental stages on phytosterol contents. It establishes an analytical method for phytosterols and provides a foundation for the utilization of pollen and anther wall in functional foods and pharmaceutical industry.

Summary: The role of anther characteristics in orchid taxonomy, cladistic analysis, and understanding the development and evolution of various traits is significant. In this study, Herminium lanceum was selected to investigate these characteristics due to the lack of information. The anther of this taxon developed two thecae with wedge-shaped, rectangular or triangular massulae through repeated cell divisions. The anther wall consisted of different layers, and various types of microspore tetrads were observed. The study also revealed the formation of bipartite sectile pollinium.

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: 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 developmental characteristics of pollen in the orchid Dendrobium officinale were examined using electron microscopy and light microscopy combined with calcium localization analyses. The study found that before anthesis, the anther wall of D. officinale consists of different layers of cells, and the tapetal cells degenerate while the endothecium cells develop fibrous bands. The microspores in the tetrad of D. officinale do not separate from each other after meiosis, instead, they develop together to form the pollinium.

Summary: Rice is a crucial crop for feeding the world's population, and the future demands of population growth and climate change necessitate advancements in rice improvement. Recent developments in rice genomics have shed light on the vital role of the non-coding portion of the genome. Long non-coding RNAs, including linear non-coding RNAs (lncRNAs) and circular non-coding RNAs (circRNAs), have been shown to play critical roles in various developmental processes related to reproduction and fertility control in rice.
