Abstract
Signal transduction mediated by photoreceptors regulates many physiological processes during plant growth and development including seed germination, flowering and photosynthesis, which are also regulated by hydrogen sulfide (H2S). However, studies of the connection between the vital environmental factors - light and the significant endogenous gasotransmitter - H2S, is lacking. Here, the seedlings of foxtail millet were used to reveal the mechanism of light regulation in H2S generation. Results showed that seedling hypocotyl elongation was promoted by H2S, but inhibited by HA under dark or white light condition. H2S contents in hypocotyl increased at first under red, blue or white light then decreased, and the duration of increase under white light was longer than under red or blue light. The activity of cysteine desulfhydrases, which catalyse H2S generation, was increased by red light but decreased by blue and white light. The expressions of cysteine desulfhydrases coding genes LCD1 and LCD2 were promoted by red or white light, but inhibited by blue light. In contrast, DES gene was promoted by white light but inhibited by red or blue light. In addition, the activities of LCDs were regulated by the phosphorylation mediated by photoreceptors PHYB and CRY1/CRY2. Finally, there are two pathways of light regulating H2S production, including a rapid process that involves the modification of phosphorylation on LCDs protein mediated by photoreceptors directly or indirectly, as well as a slower process that involves in regulating the expressions of LCDs and DES genes. This discovery has potential value for the application of H2S in agricultural production protecting the crops from unsuited light condition.

Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
