Imaging plant embryos at the cellular level over time is technically challenging, since the embryo, once its protective seed coat is removed, must be kept viable and unstressed on a microscope slide for the duration of the experiment. Here we describe a procedure and suitable apparatus for the visualization, over several days, of changes in endoplasmic reticulum (ER) morphology associated with the process of germination in Arabidopsis thaliana seeds. Moreover, we also present a user-friendly image analysis tool which enables subtle perturbations in the ER network to be measured.

Iron is a potent biochemical, and accurate homeostatic control is orchestrated by a network of interacting players at multiple levels. Although our understanding of organismal iron homeostasis has advanced, intracellular iron homeostasis is poorly understood, including coordination between organelles and iron export into the ER/Golgi. Here, we show that SLC39A13 (ZIP13), previously identified as a zinc transporter, promotes intracellular iron transport and reduces intracellular iron levels.

Lipid metabolism is critical for male reproduction in plants. Many lipid-metabolic genic male-sterility (GMS) genes function in the anther tapetal endoplasmic reticulum, while little is known about GMS genes involved in de novo fatty acid biosynthesis in the anther tapetal plastid. In this study, we identify a maize male-sterile mutant, enr1, with early tapetal degradation, defective anther cuticle, and pollen exine.

Hepatic fibrosis, a degenerative liver lesion, significantly contributes to the deterioration and mortality among patients with chronic liver diseases. The condition arises from various factors including toxins, such as alcohol, infections like different types of viral hepatitis, and metabolic diseases. Currently, there are no effective treatments available for liver fibrosis.

Background: B-cell receptor-associated protein 31 (BCAP31) is a widely expressed transmembrane protein primarily located in the endoplasmic reticulum (ER), including the ER-mitochondria associated membranes. Emerging evidence suggests that BCAP31 may play a role in cancer development and progression, although its specific effects across different cancer types remain incompletely understood.
Methods: The raw data on BCAP31 expression in tumor and adjacent non-tumor (paracancerous) samples were obtained from the Broad Institute Cancer Cell Line Encyclopedia (CCLE) and UCSC databases.

Saline-alkali soil severely reduces the productivity of crops, including maize (Zea mays). Although several genes associated with saline-alkali tolerance have been identified in maize, the underlying regulatory mechanism remains elusive. Here, we report a direct link between colonization by arbuscular mycorrhizal fungi (AMF) and saline-alkali tolerance in maize.
