Abstract
Plant evolutionary research has made leaps in exploring the deep evolutionary roots of embryophytes. A solid phylogenomic framework was established, allowing evolutionary inferences. Comparative genomic approaches revealed that many genes coding for transcription factors, morphogenetic regulators, specialized metabolic enzymes, phytohormone signaling, and more are not innovations of land plants but have a deep streptophyte algal ancestry. Are these just spurious homologs, or do they actualize traits we deem important in embryophytes? Building on streptophyte algae genome data, current endeavors delve into the functional significance of whole cohorts of homologs by leveraging the power of comparative high-throughput approaches. This ushered in the identification of recurrent themes in function, ultimately providing a functional genomic definition for the toolkit of plant terrestrialization.
期刊介绍：
Launched in 1985, Trends in Genetics swiftly established itself as a "must-read" for geneticists, offering concise, accessible articles covering a spectrum of topics from developmental biology to evolution. This reputation endures, making TiG a cherished resource in the genetic research community. While evolving with the field, the journal now embraces new areas like genomics, epigenetics, and computational genetics, alongside its continued coverage of traditional subjects such as transcriptional regulation, population genetics, and chromosome biology.
Despite expanding its scope, the core objective of TiG remains steadfast: to furnish researchers and students with high-quality, innovative reviews, commentaries, and discussions, fostering an appreciation for advances in genetic research. Each issue of TiG presents lively and up-to-date Reviews and Opinions, alongside shorter articles like Science & Society and Spotlight pieces. Invited from leading researchers, Reviews objectively chronicle recent developments, Opinions provide a forum for debate and hypothesis, and shorter articles explore the intersection of genetics with science and policy, as well as emerging ideas in the field. All articles undergo rigorous peer-review.
