Premise: Primroses famously employ a system that simultaneously expresses distyly and filters out self-pollen. Other species in the Primulaceae family, including Lysimachia monelli (blue pimpernel), also express self-incompatibility (SI), but involving a system with distinct features and an unknown molecular genetic basis.

Methods: We utilize a candidate-based transcriptome sequencing (RNA-seq) approach, relying on candidate T2/S-RNase Class III and S-linked F-box-motif-containing genes and harnessing the unusual evolutionary and genetic features of SI, to examine whether an RNase-based mechanism underlies SI in L.

Background: Renal autoregulatory mechanisms modulate renal blood flow. Connecting tubule glomerular feedback (CNTGF) is a vasodilator mechanism in the connecting tubule (CNT), triggered paracrinally when high sodium levels are detected via the epithelial sodium channel (ENaC). The primary activation factor of CNTGF-whether NaCl concentration, independent luminal flow, or the combined total sodium delivery-is still unclear.

Purpose Of Review: The thick ascending limb (TAL) of loop of Henle is essential for NaCl, calcium and magnesium homeostasis, pH balance and for urine concentration. NKCC2 is the main transporter for NaCl reabsorption in the TAL and its regulation is very complex. There have been recent advancements toward understanding how NKCC2 is regulated by protein trafficking, protein-protein interaction, and phosphorylation/dephosphorylation.

Science education plays a crucial role in addressing the pollinator crisis by enhancing knowledge and fostering changes in attitudes toward this environmental challenge. Previous research has been focused on validating a specific instrument related to this subject, although its use for assessing students' knowledge has been little explored. In the present study, we have evaluated the level of awareness regarding the significance of bees as primary pollinators among students of various disciplines at the Universities of Sevilla, in Spain, and Ouro Preto, in Brazil, emphasizing the importance of the plant-bee interaction.
