Katayama et al. perform transcriptome-based molecular evolutionary analyses on eight species from the aquatic plant family Podostemaceae to investigate its evolutionary history of mutation rate and genes under positive selection. Their results show t

Late Silurian to early Devonian lycophytes had prostrate aerial axes, while subordinate organs or subterranean axes were formed around the dichotomies of the axes. The subterranean axes are hypothesized to have evolved into root-bearing axes (rhizoph

The independent origin of roots in lycophytes and euphyllophytes has been proposed, mainly based on paleobotanical records. However, the question of how roots evolved within these lineages remains unresolved. Root apical meristem (RAM) organization i

Mycorrhizal symbiosis between plants and fungi is ubiquitous, and has been played key roles in plant terrestrialization and diversification. Although arbuscular mycorrhizal (AM) symbioses with Glomeromycotina fungi have long been recognized as both a

Shoots of the aquatic eudicot family, Podostemaceae, exhibit unusual organogenesis with mixed leaf and stem identities. New shoots arise at the base of the older shoot with shoot apical meristem (SAM) identity but the entire SAM differentiates into a

Roots have played a pivotal role in the conquest of land by vascular plants, yet their origin has remained enigmatic. Palaeobotanical evidence suggests that roots may have originated from subterranean shoots in some lycophyte species. If this hypothe

Premise of the study The apical meristem generates indeterminate apical growth of the stem and root of vascular plants. Our previous examination showed that shoot apical meristems (SAMs) can be classified into two types based on plasmodesmatal networ

To determine the mycorrhizal status of pteridophyte gametophytes in diverse taxa, the mycorrhizal colonization of wild gametophytes was investigated in terrestrial cordate gametophytes of pre-polypod leptosporangiate ferns, i.e., one species of Osmun

PREMISE OF THE STUDY Podostemaceae is a unique family of aquatic angiosperms that grow in swift-running water on rock surfaces in the tropics. Their plant bodies show a remarkable adaptation: the main plant body is mostly creeping or flattened, or in

Premise of the study Understanding the origin and early evolution of vascular plants requires thorough consideration of the gametophyte generation of ferns and lycophytes. Unfortunately, information about this generation is quite limited. To reveal t
