🧬⚡️ SPECIAL ISSUE REVIEW 🧬⚡️

This review considers the multilayered strategies that plants employ to protect themselves from the detrimental effects of DNA-damaging UV radiation, thereby maintaining the stability of their genomes - Asik et al.

#PlantScience 🧪
Fig. 3 (shortened, full legend in paper): Plant mechanisms to maintain genome stability under UV stress. Plants shield against UVB with the help of flavonoid molecules; however, it still penetrates the nucleus and causes formation of pyrimidine dimers on the genome. These dimers can be eliminated by photoreactivation and nucleotide excision repair. In photoreactivation, photolyase enzymes bind to the pyrimidine dimers and reverse them to the undamaged state using blue light as an energy source. As an alternative mechanism, the nucleotide excision repair pathway can detect the pyrimidine dimers and excise the dimer-containing oligonucleotide (mainly 27 nucleotides in length) by dual incision. The resulting gap is filled by polymerase and ligase activities. To maintain DNA replication in the presence of pyrimidine dimers that block the elongation of replicative DNA polymerase, plants employ translesion synthesis (TLS) polymerases, which can bypass the damage site.

We created a new tool that uses prescription label information to identify where your drug was made.

It also lets you see if and when that factory was inspected for quality and safety violations.

Try it out 👇
Where Was My Generic Prescription Drug Made? - Rx Inspector - ProPublica
The FDA won’t tell Americans where their generic drugs are made, so ProPublica did it instead. Use information on your prescription label to locate the factory and see inspection reports.

🔬 SPECIAL ISSUE REVIEW 🔬

📝 This review by Hazelwood et al. highlights the discoveries focused on nuclear position manipulation and the importance of nuclear position in deciding future cell division sites.

(B) During volumetrically equal asymmetric cell division, the nucleus moves to the center of the cell. (C) During volumetrically distinct asymmetric cell division, the nucleus moves towards the polarized direction.

Most birds molt a few feathers at a time. But some species, like the Northern cardinal, do away with all of their head feathers at once. Comment "✋🏽" if you've seen a bald cardinal before. Comment "👎🏽" if you haven't and this really weirds you out. #ChristmasBirdCount

📷 : Comic by @rosemarymosco.com
"Know Your Northern Cardinals" comic by illustrator and author Rosemary Mosco. In the upper left-hand corner, there is a juvenile with brown feathers, a brown beak, and a crest. In the upper right-hand corner, there is an adult male with red feathers, red beak, and a crest. In the lower left-hand corner, there is a molting male cardinal, missing all of its head feathers but a few random crest feathers. Rosemary Mosco calls this a "bloödcheëp." In the lower right-hand corner, there is a female cardinal with brown feathers, a red beak, and a crest.

- Lysosomal damage response Review

journals.biologists.com/jcs/issue/13...
Overview of the LDR. Lysosomal stress and membrane damage are triggered by diverse harmful factors, including physical stressors (e.g. silica and crystals), oxidative stress, lipid peroxidation, amyloid fibrils and bacterial infection. Lysosomal damage leads to the leakage of lysosomal contents such as cathepsins (a type of lysosomal protease) and protons into the cytosol. This causes proteolytic damage, mitochondrial dysfunction, inflammation and potentially cell death, ultimately resulting in accelerated aging and disease (e.g. neurodegeneration, kidney injury). The LDR involves at least three pathways – membrane repair, removal of damaged lysosomes, and lysosome biogenesis and regeneration. The activation of these pathways depends on the extent, duration and severity of the damage (double-headed arrows). Mild or transient stress or damage is rapidly resolved within seconds to minutes through lysosomal membrane repair mechanisms. When the damage exceeds the repair capacity, indicated by persistent rupture or exposure of luminal glycoproteins, the cell initiates selective autophagy of damaged lysosomes (called lysophagy). In addition, when damage is widespread or chronic, and functional lysosomes are depleted, lysosome biogenesis and regeneration occur.

🌲 RESEARCH 🌲

¹³CO₂ pulse labelling shows that Qinghai spruce, employing a conservative carbon allocation strategy, prioritizes non-structural carbohydrate storage over growth & allocates more newly assimilated carbon to roots under drought - Li et al.

🔗 doi.org/10.1093/jxb/...
#PlantScience 🧪
Fig. 6.Overview of the effects of drought on C allocation in Qinghai spruce seedlings. The proportion (mean ±SE) of 13C released (through respiration and unknown processes) and retained (in tree biomass and soil) at day 11 after pulse-labelling was estimated based on the total 13C uptake during a 3 h 13CO2 pulse-labelling. The retention of 13C in tree biomass shows the proportion of 13C retained in needles, stems, and roots, respectively. The asterisks represent significant differences between the control and drought treatment conditions. **P < 0.01, *P < 0.05.

This Special Issue reveals that root responses depend on where the root is, when it develops and the evolutionary history behind it. Recognizing this context-dependence moves us beyond simple models and toward more realistic predictions of plant resilience.
