Pan-genomic insights into RLK family evolution and adaptation in Dioscorea alata.

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
Dioscorea alata (greater yam) is a vital tuber crop underpinning global food security, while this crop suffers great reduction due to diseases like anthracnose, yam mosaic virus, and tuber rot. Receptor-like kinases (RLKs) play pivotal role in plant disease resistance, transducing plant immune signal. Yet the evolutionary dynamics of RLKs remain underexplored in D. alata. Here, we leveraged seven chromosome-level D. alata genomes to characterize the pan-RLKome of D. alata, identifying 4,119 RLK genes across 48 subfamilies. Our analysis revealed moderate variation in total RLK numbers but striking subfamily-specific expansions on several chromosome hotspots driven primarily by whole-genome/segmental duplication. Phylogenomic reconstruction uncovered pervasive extracellular domain swaps, fusions, and losses, contributing to diversified RLK architectures. Selection pressure analyses showed that purifying selection has maintained core RLK functions, while positive selection drove adaptive evolution in stress-associated subfamilies. Our study uncovers the pan-genomic basis of RLK evolution in D. alata, highlighting how duplication mechanisms and domain plasticity underpin functional innovation and environmental adaptation in this vital crop.
