Ovule development and pollen tube growth in Tsuga chinensis: insights into the evolution of siphonogamy.
Article in Plant cell reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
key messageConfirmation of the correlation between archegonium development and pollen tube guidance and identification of putative genes implicated in male‒female interactions in gymnosperms. Studying angiosperm-like siphonogamy in gymnosperms will increase our understanding of seed plant evolution. This study involved an exploration of pollination and ovule development in Tsuga chinensis, which is an interesting gymnosperm species endemic to East Asia that exhibits angiosperm-like siphonogamy. Using comprehensive morphological approaches, we determined that the mechanism underlying T. chinensis pollination involves the germination of pollen grains outside the ovule and the growth of pollen tubes into the micropyle. Furthermore, a correlation between the timing of archegonial appearance and pollen tube growth was confirmed. Additionally, transcriptome sequencing revealed 19,643 DEGs that are involved in ovule development. Through bioinformatics analysis, we identified several putative genes that are involved in male‒female interactions in gymnosperms, and further validation of the functions of these DEGs is worthwhile. These findings offer valuable insights into the progression of the complex evolution of siphonogamy across seed plants and lay a foundation for understanding the molecular mechanisms underlying siphonogamy in gymnosperms.
