RCD1 and SRO1 are necessary to maintain meristematic fate in Arabidopsis thaliana
Bibliographic record
Abstract
The radical-induced cell death1 and similar to RCD ONE1 genes of Arabidopsis thaliana encode members of the poly(ADP-ribose) polymerase (PARP) superfamily and have pleiotropic functions in development and abiotic stress response. In order to begin to understand the developmental and molecular bases of the defects seen in rcd1-3; sro1-1 plants, this study used the root as a model. Double mutant roots are short and display abnormally organized root apical meristems. However, acquisition of most cell fates within the root is not significantly disrupted. The identity of the quiescent centre is compromised, the zone of cell division is smaller than in wild-type roots and abnormal divisions are common, suggesting that RCD1 and SRO1 are necessary to maintain cells in a division-competent state and to regulate division plane placement. In addition, differentiation of several cell types is disrupted in rcd1-3; sro1-1 roots and shoots, demonstrating that RCD1 and SRO1 are also necessary for proper cell differentiation. Based on the data shown in this article and previous work, we hypothesize that RCD1 and SRO1 are involved in redox control and, in their absence, an altered redox balance leads to abnormal development.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
