Article Synopsis
- Chloroplasts are important for how plants grow and adapt to tough conditions like stress.
- A study looked at a special plant mutant called noxy8 and found that two related proteins, CLPC1 and CLPC2, have different jobs in the chloroplasts.
- CLPC1 helps keep everything running smoothly, while CLPC2 is more involved when the plant is fighting off infections, meaning they both play unique roles in how plants survive and respond to problems.
Article Synopsis
- Plants have a “memory” for past stresses, especially pathogens, which enhances their resistance to future infections, showing great potential for agriculture.
- A study revealed that inducing mitochondrial stress in plants leads to a specific type of resistance (MS-IR) that is effective both locally and across generations, indicated by epigenetic changes in gene expression.
- Key mechanisms involve increased positive epigenetic marks and DNA modifications that help transmit this resistance, highlighting mitochondria as crucial in sensing environmental stress and shaping plant responses.
Plant oxylipins are signaling molecules produced from fatty acids by oxidative pathways, mainly initiated by 9- and 13-lipoxygenases (9-LOX and 13-LOX), alpha-dioxygenases or non-enzymatic oxidation. Oxylipins from the 9-LOX pathway induce oxidative stress and control root development and plant defense. These activities have been associated with mitochondrial processes, but precise cellular targets and pathways remain unknown.

- Scientists studied a special plant called Arabidopsis thaliana to learn how it deals with stress by looking at a mutation called noxy7.
- They found that the noxy7 mutation is connected to a protein that helps control how proteins are made when the plant is stressed, similar to how some yeast and mammals do it.
- The study showed that the noxy7 mutation helps plants adapt to tough situations like lack of food or infections, but it works in a different way than in yeast and animals.
The management of angio-oedema is quite complicated because of the frequent poor response to usual treatments, including H1 antihistamines, systemic corticosteroids, immunosuppressant drugs, antileucotriene drugs or tranexamic acid. Omalizumab, an anti-immunoglobulin (Ig)-E antibody, has shown good resuts in chronic spontaneous urticaria, and might also be a good option for angio-oedema. To our knowledge, there have been eight relevant case reports published in the English literature.
