Xyloglucan evolution and the terrestrialization of green plants

Open access

Abstract

Summary: Xyloglucan (XyG) is the major noncellulosic nonpectic matrix polysaccharide in cell walls of most land plants. Initially thought to be restricted to land plants, the last decade has seen the detection of XyG and the discovery of synthesis and modification/degradation genes in charophycean green algae (CGA). Recently, a totally new function of XyG was discovered as a potent soil aggregator released by roots and rhizoids of all major groups of land plants. In this Viewpoint, I show the presence of a complex XyG genetic machinery in most CGA groups. I discuss the context of XyG evolution in light of the terrestrialization of early CGA that gave rise to embryophytes and its possible role in early soil formation.

  • The earliest ancestor of land plants is currently understood to have been a form of freshwater, terrestrial algae.

    “The earliest ancestor of land plants is currently understood to have been a form of freshwater, terrestrial algae (Kenrick and Crane, 1997; Del-Bem, 2018).”

    From The Hot Spring Hypothesis for an Origin of Life (2020) · cites this paper as Del-Bem, 2018

    In “Xyloglucan evolved during the colonization of land by charophytes” (page unavailable), Del-Bem describes charophycean green algae as ancestors of land plants and discusses a terrestrial-algal ancestry. But the paper contrasts that proposal with the more commonly held view of aquatic algae evolving near drying pools. It does not establish that a freshwater, terrestrial ancestor is the current consensus. (LLM, conf=0.85)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
