Article Synopsis
- The study explores how plants, specifically Arabidopsis, absorb inorganic carbon (like bicarbonate) through their roots and the mechanisms involved in this process.
- It was found that the absorbed carbon is incorporated mainly into sucrose and transported to the leaves, enhancing plant growth and photosynthesis.
- The research also highlighted the role of specific transporters and signaling pathways, suggesting that these processes support the plant's nutrient assimilation and growth when inorganic carbon is available.
Article Synopsis
- The study aimed to investigate how low temperatures experienced by rice leaves influence stress responses in the roots and how light conditions affect these processes.
- Researchers exposed rice plants to low temperatures (12°C) while keeping roots at normal temperatures (27°C) and analyzed gene expression changes in the roots.
- Findings revealed that low temperature exposure led to more down-regulated genes, particularly affecting nitrogen metabolism and related signaling, with additional insights from real-time PCR and metabolomics showing that both leaf cold exposure and light conditions impact root stress responses.
DEFENSE NO DEATH 1 (DND1) is a cyclic nucleotide-gated ion channel protein. Earlier, it was shown that the silencing of DND1 in the potato (Solanum tuberosum L.) leads to resistance to late blight, powdery mildew, and gray mold diseases.

This study aims to better understand the plant defence mechanisms regulated by red light, in particular, the effects of red light at night when most phytopathogens are highly infectious. Our results showed that superoxide production significantly increased immediately after red light exposure and, together with hydrogen peroxide levels, was highest at dawn after 30 min of nocturnal red-light treatment.
