THE PLANT JOURNAL : FOR CELL AND MOLECULAR BIOLOGY 2024; 119:445-459. [PMID: 38652016 DOI: 10.1111/tpj.16775] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/01/2024] [Revised: 03/15/2024] [Accepted: 04/04/2024] [Indexed: 04/25/2024]
Abstract
The lycophyte Phylloglossum drummondii is the sole inhabitant of its genus in the Huperzioideae group and one of a small minority of plants which perform uridine to cytidine RNA editing. We assembled the P. drummondii chloroplast and mitochondrial genomes and used RNA sequence data to build a comprehensive profile of organellar RNA editing events. In addition to many C-to-U editing events in both organelles, we found just four U-to-C editing events in the mitochondrial transcripts cob, nad1, nad5 and rpl2. These events are conserved in related lycophytes in the genera Huperzia and Phlegmariurus. De novo transcriptomes for three of these lycophytes were assembled to search for putative U-to-C RNA editing enzymes. Four putative U-to-C editing factors could be matched to the four mitochondrial U-to-C editing sites. Due to the unusually few numbers of U-to-C RNA editing sites, P. drummondii and related lycophytes are useful models for studying this poorly understood mechanism.

Ambrose BA, Stevenson DW. The evolution and development of sporangia-The fundamental reproductive organ of land plant sporophytes. CURRENT OPINION IN PLANT BIOLOGY 2024; 81:102563.

Abstract
A key innovation of land plants is the origin and evolution of the sporangium, the fundamental reproductive structure of the diploid sporophyte. In vascular plants, whether the structure is a cone, fertile leaf, or flower-all are clusters of sporangia. The evolution of morphologically distinct sporangia (heterospory) and retention of the gametophyte evolved three times independently as a prerequisite for the evolution of seeds. This review summarizes the development of vascular plant sporangia, molecular genetics of angiosperm sporangia, and provides a framework to investigate evolution and development in vascular plant sporangia.

Extraordinary preservation of gene collinearity over three hundred million years revealed in homosporous lycophytes. Proc Natl Acad Sci U S A 2024; 121:e2312607121.

Abstract
Homosporous lycophytes (Lycopodiaceae) are a deeply diverged lineage in the plant tree of life, having split from heterosporous lycophytes (Selaginella and Isoetes) ~400 Mya. Compared to the heterosporous lineage, Lycopodiaceae has markedly larger genome sizes and remains the last major plant clade for which no chromosome-level assembly has been available. Here, we present chromosomal genome assemblies for two homosporous lycophyte species, the allotetraploid Huperzia asiatica and the diploid Diphasiastrum complanatum. Remarkably, despite that the two species diverged ~350 Mya, around 30% of the genes are still in syntenic blocks. Furthermore, both genomes had undergone independent whole genome duplications, and the resulting intragenomic syntenies have likewise been preserved relatively well. Such slow genome evolution over deep time is in stark contrast to heterosporous lycophytes and is correlated with a decelerated rate of nucleotide substitution. Together, the genomes of H. asiatica and D. complanatum not only fill a crucial gap in the plant genomic landscape but also highlight a potentially meaningful genomic contrast between homosporous and heterosporous species.

Abstract
Angiosperms represent most plants that humans cultivate, grow, and eat. However, angiosperms are only one of five major land plant lineages. As a whole lineage, plants also include algal groups. All these clades represent a tremendous genetic diversity that can be investigated to reveal the evolutionary history of any given mechanism. In this review, we describe the current model of the plant immune system, discuss its evolution based on the recent literature, and propose future directions for the field. In angiosperms, plant-microbe interactions have been intensively studied, revealing essential cell surface and intracellular immune receptors, as well as metabolic and hormonal defense pathways. Exploring diversity at the genomic and functional levels demonstrates the conservation of these pathways across land plants, some of which are beyond plants. On basis of the conserved mechanisms, lineage-specific variations have occurred, leading to diversified reservoirs of immune mechanisms. In rare cases, this diversity has been harnessed and successfully transferred to other species by integration of wild immune receptors or engineering of novel forms of receptors for improved resistance to pathogens. We propose that exploring further the diversity of immune mechanisms in the whole plant lineage will reveal completely novel sources of resistance to be deployed in crops.

Chromosome-level reference genome of tetraploid Isoetes sinensis provides insights into evolution and adaption of lycophytes. Gigascience 2022; 12:giad079.

Abstract
BACKGROUND The Lycophyta species are the extant taxa most similar to early vascular plants that were once abundant on Earth. However, their distribution has greatly diminished. So far, the absence of chromosome-level assembled lycophyte genomes has hindered our understanding of evolution and environmental adaption of lycophytes. FINDINGS We present the reference genome of the tetraploid aquatic quillwort, Isoetes sinensis, a lycophyte. This genome represents the first chromosome-level assembled genome of a tetraploid seed-free plant. Comparison of genomes between I. sinensis and Isoetestaiwanensis revealed conserved and different genomic features between diploid and polyploid lycophytes. Comparison of the I. sinensis genome with those of other species representing the evolutionary lineages of green plants revealed the inherited genetic tools for transcriptional regulation and most phytohormones in I. sinensis. The presence and absence of key genes related to development and stress responses provide insights into environmental adaption of lycophytes. CONCLUSIONS The high-quality reference genome and genomic analysis presented in this study are crucial for future genetic and environmental studies of not only I. sinensis but also other lycophytes.
