The exocyst is a conserved octameric vesicle-tethering complex essential for targeted secretion. It is organized into two modules (I: SEC3, SEC5, SEC6, SEC8; II: SEC10, SEC15, EXO70, EXO84). In plants...

In roots, the endodermis controls nutrient entry by forming a barrier known as the Casparian strip. Yet how barrier-associated processes interface with systemic signaling remains unclear. Here, we sho...

While root nodule symbiosis (RNS) is primarily recognized for nitrogen acquisition, it is heavily influenced by phosphorus levels. In natural agroecosystems, nitrogen limitation frequently co-occurs with phosphorus deficiency, yet the role of phosphorus in modulating RNS remains understudied. Recent research in the legume Phaseolus vulgaris shows that phosphorus starvation suppresses nodulation by downregulating the master regulator gene Nodule Inception, mediated by phosphate-responsive factors such as Phosphate Starvation Response-Like 7. We propose an integrated model where phosphate signaling functions as a metabolic checkpoint, balancing carbon availability, nitrogen demand, and phosphorus status. Elucidating how phosphate scarcity rewires these symbiotic gene networks is essential for sustainable agriculture, allowing for the optimization of symbiotic nitrogen fixation in nutrient-depleted environments.

The vascular cambium contains bifacial stem cells producing secondary phloem in one and secondary xylem to the opposite direction. In Arabidopsis r...

Plant roots release exudates to encourage microbiome assembly, which influences the function and stress resilience of plants. How specific exudates drive spatial colonization patterns remains largely ...

Plants and animals detect microbe-associated molecular patterns (MAMPs) to initiate defense responses. Both lineages employ pattern recognition receptors (PRRs), yet plant mechanisms for sensing Gram-...

Sea slugs steal foreign chloroplasts and store them in specialized organelles that facilitate photosynthesis and eventual digestion to mediate starvation resistance.

In Arabidopsis, transcriptional factors LEC2 and SPCH enhance local auxin biosynthesis, establishing a transcriptional framework that enables differentiated single somatic epidermal cells to regain to...

When we created this site to write about things in science that need to be fixed, we chose not to start with publishing, even though it has been our preoccupation for decades.
