Non-chlorophyllous and crypto-chlorophyllous fern spores differ in their mobilisation of fatty acids during priming. [PDF]

Physiol Plant, 2023
Abstract During fern spore germination, lipid hydrolysis primarily provides the energy to activate their metabolism. In this research, fatty acids (linoleic, oleic, palmitic and stearic) were quantified in the spores exposed or not to priming (hydration–dehydration treatments).

Distribution model and prediction of the tree fern Alsophila costularis Baker (Cyatheaceae) in China. [PDF]

Ecol Evol
We employed an optimized MaxEnt model to evaluate the relative contribution of each bioclimatic variable and predict the suitable habitat for Alsophila costularis Baker under past, current, and future climate scenarios, which is an endangered relict tree fern known as a living fossil.

Effective dispersal of fern spore and the ecological relevance of zoochory. [PDF]

Biol Rev Camb Philos Soc
ABSTRACT The mechanisms of fern dispersal are under‐studied and there are few data to support the vectors assumed to drive patterns of sporophyte occurrence and speciation. Although wind is generally the fern spore dispersal vector described in the literature, there has always been competing evidence supporting alternate vectors.

Non‐seed plants are emerging gene sources for agriculture and insect control proteins

The Plant Journal, Volume 116, Issue 1, Page 23-37, October 2023., 2023
SUMMARY The non‐seed plants (e.g., charophyte algae, bryophytes, and ferns) have multiple human uses, but their contributions to agriculture and research have lagged behind seed plants. While sharing broadly conserved biology with seed plants and the major crops, non‐seed plants sometimes possess alternative molecular and physiological adaptations ...

Restoration of threatened plant species in Limahuli Valley on the Hawaiian Island of Kaua'i in the framework of the Global Tree Assessment

PLANTS, PEOPLE, PLANET, Volume 5, Issue 4, Page 547-562, July 2023., 2023
Trees are an important part of many ecosystems. The Global Tree Assessment data can be used to focus conservation and restoration efforts for the circa 30% of tree species that are threatened worldwide. The conservation status for the tree flora of Limahuli Valley on Kaua'i Island and a restoration plan for 11 endangered tree species is evaluated in ...

The ecology and physiology of fern gametophytes: A methodological synthesis

Applications in Plant Sciences, Volume 10, Issue 2, March-April 2022., 2022
Abstract All green plants alternate between the gametophyte and sporophyte life stages, but only seed‐free vascular plants (ferns and lycophytes) have independent, free‐living gametophytes. Fern and lycophyte gametophytes are significantly reduced in size and morphological complexity relative to their sporophytic counterparts and have often been ...

Identifying cryptic fern gametophytes using DNA barcoding: A review

Applications in Plant Sciences, Volume 10, Issue 2, March-April 2022., 2022
Abstract Ferns and lycophytes are unique among land plants in having sporophyte (diploid) and gametophyte (haploid) generations that can grow independently of each other. While most studies of fern ecology focus on the more visible sporophytic stage, the gametophyte is critically important, as it is the sexual phase of the life cycle.
