Article Synopsis
- - Plant lipid transfer proteins (LTPs) are crucial for moving lipids between membranes, impacting pollen wall development, including the pollen aperture structure.
- - The study focuses on a rice mutant called pollen aperture defect 1 (Ospad1), which shows male sterility due to abnormal pollen grain development linked to a non-specific LTP that fails to properly bind lipids.
- - Researchers found that OsPAD1 interacts with a gene involved in pollen development, providing new insights into how LTPs function in forming pollen apertures, which could have broader implications for other cereal crops.
In higher plants, mature male gametophytes have distinct apertures. After pollination, pollen grains germinate, and a pollen tube grows from the aperture to deliver sperm cells to the embryo sac, completing fertilization. In rice, the pollen aperture has a single-pore structure with a collar-like annulus and a plug-like operculum.

This paper analyzes the core issue of Japan's plan to discharge nuclear contaminated water into the ocean from the perspectives of Japan's international legal obligation, law enforcement issues, and judicial issues after integrated analyzing academic research paper and cases. Japan has obligations such as timely notification, information disclosure, environmental impact assessment, and avoidance of transboundary harm.

- Research identified a specific male sterility locus on chromosome 4 in hybrids of African cultivated rice and Asian cultivated rice, causing pollen semi-sterility.
- The study found that non-functional pollen grains abort at the late bicellular stage and have a distortion in male gametogenesis when carrying the allele from the rice variety DJY1.
- Future efforts will focus on map-based cloning to further understand the molecular mechanisms behind hybrid sterility between these two rice species.
Meiosis plays an essential role in the production of male and female gametes. Extensive studies have elucidated that homologous chromosome association and pairing are essential for crossing-over and recombination of chromosomal segments. However, the molecular mechanism of chromosome recognition and pairing remains elusive.
