    What's a GeneRIF?
    1. The data support the hypothesis that AXY3/XYL1 is an essential component of the apoplastic xyloglucan degradation machinery.
      Title: AXY3 encodes a α-xylosidase that impacts the structure and accessibility of the hemicellulose xyloglucan in Arabidopsis plant cell walls.
    2. Organ elongation is affected in alpha-xylosidase deficient plants, and xyloglucan oligosaccharides accumulate in the growth medium.
