OsFLA1 encodes a fasciclin-like arabinogalactan protein and affects pollen exine development in rice.
Article in TAG. Theoretical and applied genetics. Theoretische und angewandte Genetik, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
key messageOsFLA1 positively regulates pollen exine development, and locates in the cellular membrane. Arabinogalactan proteins are a type of hydroxyproline-rich glycoprotein that are present in all plant tissues and cells and play important roles in plant growth and development. Little information is available on the participation of fasciclin-like arabinogalactan proteins in sexual reproduction in rice. In this study, a rice male-sterile mutant, osfla1, was isolated from an ethylmethanesulfonate-induced mutant library. The osfla1 mutant produced withered, shrunken, and abortive pollen. The gene OsFLA1 encoded a FLA protein and was expressed strongly in the anthers in rice. Subcellular localization showed that OsFLA1 was located in the cellular membrane. In the osfla1 mutant, abnormal Ubisch bodies and a discontinuous nexine layer of the microspore wall were observed, which resulted in pollen abortion and ultimately in male sterility. The results show the important role that OsFLA1 plays in male reproductive development in rice.
