Article Synopsis
- - The study focuses on an Arabidopsis mutant that has a defect in the sterolmethyltransferase2 (SMT2) enzyme, leading to significant growth issues and a loss of specific sterols, indicating the unique function of C-24 ethyl sterols in growth.
- - Fluorescent labeling of sterol biosynthetic enzymes showed that SMT2-GFP is located in the endoplasmic reticulum during interphase but relocates to the division plane during cell division, revealing that this movement is not linked to the transport of cytokinetic vesicles.
- - The abnormal division processes are accompanied by poor cytoskeletal organization and a failure to establish proper cell wall structures in daughter cells, suggesting that C-24
Land plants are a monophyletic group of photosynthetic eukaryotes that diverged from streptophyte algae about 470 million years ago. During both the alternating haploid and diploid stages of the life cycle, land plants form multicellular bodies. The haploid multicellular body (gametophyte) produces progenitor cells that give rise to gametes and the reproductive organs.

Here, we demonstrate that a syntaxin of plants (SYP)123-vesicle-associated membrane protein (VAMP)727-dependent secretion system delivers secondary cell wall components for hardening the subapical zone and shank of Arabidopsis (Arabidopsis thaliana) root hairs. We found increased SYP123 localization at the plasma membrane (PM) of the subapical and shank zones compared with the tip region in elongating root hairs.

Bryophytes employ motile sperm (spermatozoids) as male gametes, which locomote to the egg cells to accomplish fertilization. The spermatozoids of bryophytes harbor distinctive morphological characteristics, including a cell body with a helical shape and two flagella.

- Land plant spermatozoids have unique features like spline structures, multilayered structures, and multiple flagella, but the processes behind their development (spermatogenesis) are not fully understood.
- Researchers identified specific genes, known as BLD10s, that play a crucial role in sperm development by analyzing genetic data and testing their functions in liverworts and mosses.
- Mutations in BLD10 genes lead to issues in cell structure during sperm formation, indicating that these genes are important for proper chromatin organization and cellular changes necessary for sperm production.
