Cell cycle duration in the root apical meristem (RAM) of angiosperms
In plant studies it is essential to determine cell cycle duration (T). Zhukovskaya et al. have previously proposed an exponential model evaluating T in the root

Sphagnoid areolation pattern in leaves of Palaeozoic protosphagnalean mosses
Palaeozoic Protosphagnales constitute the largest group of extinct mosses of a still uncertain affinity. Their leaf areolation resembles that of modern Sphagna, which is strikingly different

SLAD: Subero-lignified apical deposit in the root tip
Morphological response of radish (Raphanus sativus, Brassicaceae) roots exposed to toxic concentration of copper (Cu) include many root growth changes. Kováč et al. find that such

Root cap-mediated evaluation of soil resistance in Zea mays and the relevance of ethylene
Plant roots have to overcome a broad range of mechanical hindrances besides biological and chemical impacts. As an example, roots have to evaluate whether they sidestep

Characterization of the satellitome in lower vascular plants: the case of the endangered fern Vandenboschia speciosa
Vandenboschia speciosa is a highly vulnerable fern species, with a large genome (10.5 Gb). Haploid gametophytes and diploid sporophytes are perennial, can reproduce vegetatively, and
