During the past few years several high-quality genomes has been published from
Charophyte algae, bryophytes, lycophytes and ferns. These genomes have not only …

The utilization of stored RNA is a driving force in rapid development. Here, we show that
retention and subsequent removal of introns from pre-mRNAs regulate temporal patterns of …

An intron with an IR ratio of 0.5 means that this intron is retained in 50% of the transcripts.

Organelle genomes of land plants are predominately inherited maternally but in some cases
can also be transmitted paternally or biparentally. Compared to seed plants (> 83% genera …

Background Many rapidly develo** systems rely on the regulated translation of stored
transcripts for the formation of new proteins essential for morphogenesis. The microspores of …

Ferns are one of the most speciose lineages of land plants, and occupy an important
phylogenetic position sister to seed plants. Despite this, ferns remain one of the last groups …

Spermiogenesis is a postmeiotic process that drives development of round spermatids into
fully elongated spermatozoa. Spermatid elongation is largely controlled post …

The male gametophyte of the semi‐aquatic fern, Marsilea vestita, produces multiciliated
spermatozoids in a rapid developmental sequence that is controlled post‐transcriptionally …

Background Spermatogenesis in the semi-aquatic fern, Marsilea vestita, is a rapid,
synchronous process that is initiated when dry microspores are placed in water …

Marsilea vestita is a semiaquatic fern that produces its spores (meiotic products) as it
undergoes a process of natural desiccation. During the period of desiccation, the spores …
