Molecular mechanisms associated with rootstock-scion interactions in rubber trees.
Article in The plant genome, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Hevea brasiliensis (rubber tree) is the main source of natural rubber worldwide. In commercial plantations, high-yield rubber tree clones are propagated by grafting onto seedling rootstocks. In this study, the transcriptomes of the RRIM 600 clone grafted on different rootstocks in southeastern Brazil were evaluated. Exclusively expressed genes (EEGs) and differentially expressed genes linked to quantitative trait loci and coexpression networks were identified. The combination of an RRIM 600 scion (clone) with a non-clonal PB 235 rootstock resulted in the highest mean yield (76.03 g/tree dry rubber), followed by non-clonal IAN 873 rootstock (64.30 g/tree dry rubber). In the non-clonal IAN 873 rootstock combination, we identified the RPD3b gene, an EEG associated with the jasmonate pathway, which increases latex production. This effect was not detected in the non-clonal RRIM 600 and nonselected seed (NSS) rootstock combination, which resulted in decreased latex production. Distinct coexpression patterns were observed, with scion condition (RRIM 600): PB 235 showing stronger gene aggregation, indicating more synergistic interactions among the rubber-related genes Hevea rubber transferase, rubber elongation factor, and small rubber particle protein. In contrast, the NSS rootstocks presented a more dispersed pattern and low latex yield. Our findings highlight the importance of initiating rootstock-breeding programs to improve the production of rubber trees and provide valuable insights into the complex interactions between scions and rootstocks and their impact on latex yield in rubber trees.
