Early land plants: Plentiful but neglected nutritional resources for herbivores? [PDF]
Ecol Evol, 2022 In this paper, we explore the unknown reason(s) why herbivores rarely seem to attack early land plants like mosses and ferns. Our study, in which we looked at the performance of an arthropod and a gastropod on 15 species of such plants, yields surprising results that disqualify some of the common notions about early land plants.

Techniques for locating and analyzing subterranean Lycopodium and Diphasiastrum gametophytes in the field. [PDF]
Appl Plant Sci, 2022 Abstract Homosporous club mosses have an archaic life cycle, alternating two locationally, nutritionally, and physiologically independent generations. The sexual generation of club mosses—the gametophytes (or prothallia)—are among the least researched botanical subjects.

Water-related innovations in land plants evolved by different patterns of gene cooption and novelty. [PDF]
New Phytol, 2022 Summary The origin of land plants and their descendants was marked by the evolution of key adaptations to life in terrestrial environments such as roots, vascular tissue and stomata. Though these innovations are well characterized, the evolution of the genetic toolkit underlying their development and function is poorly understood. We analysed molecular

Desiccation tolerance in bryophytes relates to elasticity but is independent of cell wall thickness and photosynthesis. [PDF]
Physiol Plant, 2022 Abstract Mosses have been found outliers of the trade‐off between photosynthesis and bulk elastic modulus described for vascular plants. Hence, potential trade‐offs among physical features of cell walls and desiccation tolerance, water relations, and photosynthesis were assessed in bryophytes and other poikilohydric species.

TRB proteins in moss reveal their evolutionarily conserved roles in plant development and telomere maintenance. [PDF]
Plant JSignificance Statement TRB proteins in the moss P. patens are essential for normal development, telomere maintenance, and transcriptional regulation. Our findings demonstrate the evolutionary conservation of TRB functions across land plants and highlight their ancient origin in streptophytes.

Paleoclimatic implications of Lycophyta in the Gondwana of Southern Brazil [PDF]
Pesquisas em Geociências, 1995 As Lycophyta desempenharam importante papel para o desenvolvimento das associações florísticas durante o Permiano no Gondwana do sul do Brasil (Estado do Rio Grande do Sul). As afinidades botânicas de palinomorfos como Lundbladispora, Vallatisporites, Cristatisporites e impressões e compressões de Lycophyta sugerem que o clímax deste grupo ocorreu ...

Botany Letters, 2022 The leaf morphology of Selaginella species from subtropical South America show differences in structure and ultrastructure that are useful for species identification. We studied the following epidermal traits: micromorphology of stomatal types, distribution patterns of silica cells, silica cells and silica bodies of Selaginella convoluta, S ...
