Review: Optimizing nutrient transporters to enhance disease resistance in rice

Plants rely on an array of mineral nutrients for their growth, development, and reproductive processes. The molecular mechanisms governing the uptake, translocation, storage, and utilization of these essential minerals are orchestrated by specific nutrient transporters and their associated regulatory…

Translocation of a chloride channel from the Golgi to the plasma membrane helps plants adapt to salt stress

Plants adapt to salt stress by maintaining ion balance using ion transporters. While much is known about cation transporters, the role of anion transporters is less clear. Rajappa et al. focus on the chloride channel gene AtCLCf in Arabidopsis thaliana, controlled by the transcription factor WRKY9 under…

Conjugation of ATG8 to vacuolar membranes as a response to cell wall damage

ATG8 is a well-characterized protein involved in autophagy that binds to the double-membrane enclosed phagophore. In a new preprint, Julian et al. explore their finding that ATG8 binds to the single-membrane enclosed vacuolar membrane (tonoplast). They observed that this binding is enhanced by treatments…

Functional insights into the TPLATE complex: A key player in clathrin-mediated endocytosis in plant cells

Transporting cargo within a cell may seem straightforward, but it is actually an intricate task. At the plasma membrane in plant cells, this complexity is navigated by a process known as clathrin-mediated endocytosis. Central to this process are two key players: adapter protein AP-2 and the TSET/TPLATE…

Review: Integrating cellular electron microscopy with multimodal data to explore biology across space and time

Fifty years ago (1974), Albert Claude, Christian de Duve, and George Palade were awarded the Nobel Prize for their discoveries on the structural and functional organization of the cell, which Claude eloquently framed by writing, “We have entered the cell, the mansion of our birth, and started the inventory…

Review: The exocyst complex is targeted by pathogen effectors

The exocyst complex is a conserved octameric protein complex in eukaryotic cells. Its primary function is to tether secretory vesicles to the plasma membrane during the exocytosis process, and it is also involved in autophagy and host-pathogen interactions. Intriguingly, EXO70, one of the subunits of…

Evolution of the thermostability of actin-depolymerizing factors enhances pollen germination at high temperature

In angiosperms, pollen germination leads to a period of extensive polarized growth of the pollen tube, which carries the sperm nuclei to the ovule. Studies of tip growth in both pollen tubes and root hairs have contributed to a descriptive model that involves polarized vesicle movement along the cytoskeleton…

Selective autophagy of THOUSAND GRAIN WEIGHT 6 protein

Rice is a globally important crop, therefore increasing yield without compromising quality is of much interest. A reduction in the amount of the TGW6 (THOUSAND-GRAIN WEIGHT 6) protein is associated with improved grain yield and quality in rice. However, we do not fully understand how TGW6 protein levels…

Microtubule-associated proteins regulate fruit shape in tomato

Microtubule binding proteins are important in determining fruit shape by driving changes in microtubule arrangement. However, in depth molecular studies on these in tomato (Solanum lycopersicum) have been limited. Here, Bao et al. investigated the microtubule binding protein Microtubule-Associated Protein…
