Background: Seed germination and seedling establishment are two of the most critical phases in plant development. However, the molecular mechanisms underlying the effect of phosphorus on seed germination and post-germinated growth of oilseed rape are unclear so far. Here, we report the role of BnPHT1;4 in seed germination and early seedling development of Brassica napus.

However, the regulation of in this response remains poorly understood. Here, we report that is a target of the transcription factors AUXIN RESPONSE FACTOR7 (ARF7) and ARF19 and is positively regulated by auxin signaling in Arabidopsis () roots.

- Excess glutamate release from presynaptic neurons is linked to ischemic neuronal death, with CA1 pyramidal neurons being more vulnerable than CA3 neurons, hinting at distinct properties of these cells contributing to this difference.
- After ischemia, CA1 neurons showed increased dendritic spines and changes in glutamate receptor subunit expression, particularly a rise in the NR2B/NR2A ratio and a decrease in the GluR2 subunit.
- In contrast, CA3 neurons remained relatively unchanged in synaptic density and receptor expression post-ischemia, suggesting that structural changes in CA1 neurons drive delayed cell death following ischemic events.
The retina is a light-sensitive tissue of the central nervous system that is vulnerable to ischemia. The pathological mechanism underlying retinal ischemic injury is not fully understood. The purpose of this study was to investigate structural and functional changes of different types of rat retinal neurons and visual behavior following transient global ischemia.
