Identifying cryptic fern gametophytes using DNA barcoding: A review

Joel H. Nitta et al.

Summary: This article reviews the current application of DNA barcoding in fern gametophyte research and summarizes case studies that demonstrate its usefulness in understanding fern species distributions, gametophyte ecology, and community ecology. The article also proposes future research directions, including the use of next-generation DNA sequencing for in-field identification of cryptic gametophytes.

Photographic analysis of field-monitored fern gametophyte development and response to environmental stress

Jakob J. Schneller et al.

Summary: Through photographic monitoring, we discovered that the life history of fern gametophytes in temperate habitats is more similar to tropical habitats than previously believed. They are able to suspend growth during the cold season and resume in the following spring. These gametophytes can survive for several years while still retaining their reproductive capacity, allowing for extended periods of outbreeding.

Integrating tissue-direct PCR into genetic identification: An upgraded molecular ecology approach to survey fern gametophytes in the field

Yi-Hsuan Wu et al.

Summary: The study demonstrates the use of tissue-direct PCR in identifying fern gametophytes, which saves time and resources compared to traditional methods. Modern genetic tools can help overcome limitations in identifying fern gametophytes and open up new avenues for field research.

Insights into the evolutionary history and widespread occurrence of antheridiogen systems in ferns

Ondrej Hornych et al.

Summary: Sex expression in homosporous ferns is controlled by multiple factors, with one being the antheridiogen system. The response to antheridiogens varies among species, with approximately 65% of the studied species showing a response. The evolution and impact of antheridiogens on polyploidy and apomixis remain topics for further research.

Effect of laboratory and soil storage on fern spores germination

Luis Vidal Pedrero-Lopez et al.

Summary: This study compared the longevity and vigour of fern spores in ecological and laboratory conditions, showing that the moist soil environment of the cloud forest can maintain spore viability for over five months, but their vigour may decline over time, which could have implications for resource competition in later stages. Long-term studies in different soils, climates, and vegetation types are needed to further understand the ecological longevity of fern spores.
