The establishment of modern terrestrial life is indissociable from angiosperm evolution. While available molecular clock estimates age range the Paleozoic to Late Cretaceous, fossil record consistent with diversification in Early Cretaceous. time-frame evolution here estimated using a sample representing 87% families and sequences five plastid nuclear markers, implementing penalized likelihood Bayesian relaxed clocks. A literature-based review palaeontological yielded calibrations for 137...
Summary Succulent plants are widely distributed, reaching their highest diversity in arid and semi‐arid regions. Their origin diversification is thought to be associated with a global expansion of aridity. We test this hypothesis by investigating the tempo pattern Cactaceae diversification. Our results contribute understanding evolution New World Biomes. use most taxonomically complete dataset currently available for Cactaceae. estimate divergence times utilize Bayesian maximum likelihood...
• Premise of the study: Cactaceae is one most charismatic plant families because extreme succulence and outstanding diversity growth forms its members. Although cacti are conspicuous elements arid ecosystems in New World model systems for ecological anatomical studies, high morphological convergence scarcity phenotypic synapomorphies make evolutionary relationships trends among lineages difficult to understand. Methods: We performed phylogenetic analyses implementing parsimony ratchet...
ABSTRACT Much of what we know about speciation comes from detailed studies well‐known model systems. Although there have been several important syntheses on speciation, few (if any) explicitly compared among major groups across the Tree Life. Here, synthesize and compare is known key aspects taxa, including bacteria, protists, fungi, plants, animal groups. We focus three main questions. Is allopatric predominant groups? How common ecological divergence sister species (a requirement for...
The causes of the rapid diversification and extraordinary richness flowering plants (angiosperms) relative to other plant clades is a long-standing mystery. Angiosperms are only one among 10 major land (phyla) but include ∼90% species. However, most studies that have tried identify which traits might explain remarkable angiosperms focused on patterns within tested or few at single hierarchical scale. Here, we assemble database 31 diverse 678 families analyze relationships between rates...
Abstract Background The plant family Cactaceae provides some of the most striking examples adaptive evolution, expressing undeniably spectacular New World radiation succulent plants distributed across arid and semi-arid regions Americas. Cacti are widely regarded for their cultural, economic ecological value, yet they also recognized as one threatened endangered taxonomic groups on planet. Scope This paper reviews current threats to species cacti that have distributions in subtropical...
B-class MADS-box genes have been shown to be the key regulators of petal and stamen specification in several eudicot model species such as Arabidopsis thaliana, Antirrhinum majus, Petunia hybrida. Orthologs these found across angiosperms gymnosperms, it is thought that basic regulatory function B proteins conserved seed plant lineages. The evolution characterized by numerous duplications might represent elements fostering functional diversification duplicates with a deep impact on their role...
Abstract Great diversity of life forms has favored the colonization and dominance angiosperms in almost every terrestrial habitat. This is certainly case Orchidaceae, which includes epiphytes, geophytes mycoheterotrophs. In this study we investigated evolution form tribe Epidendreae focusing on clade comprised Basiphyllaea, Bletia Hexalectris . We estimated divergence dates, ancestral areas, patterns niche divergence/convergence climate preferences order to understand whether shifts can be...
The Oryza officinalis complex is the largest species group in Oryza, with more than nine from four continents, and a tertiary gene pool that can be exploited breeding programs for improvement of cultivated rice. Most diploid tetraploid members this have C genome. Using new reference genome O. officinalis, draft genomes two other eichingeri rhizomatis, we examine influence transposable elements on structure provide detailed phylogeny evolutionary history genomes. 1.6 times larger A sativa,...
Traditional agave spirits such as mezcal or tequila are produced all over Mexico using different species of Agave. Amongst them, A. angustifolia is the most popular given its agricultural extension. a wild extensively distributed from North to Central America, and previous studies show that it highly related tequilana. In regions Mexico, cultivated under types levels management, although traditional producers identify several landraces, for non-trained eye there no perceivable differences....

Our results revealed that DT grass Sporobolus stapfianus transcriptionally primed to tolerate dehydration/desiccation event response S. distinct from water stress desiccation-sensitive pyramidalis . also show largely unique, indicating recent this within angiosperms, inhibition senescence during dehydration likely...
Abstract The succulent syndrome is one of the most iconic life strategies in angiosperms, maximising water storage through a suite adaptations to water-scarcity. Though succulence considered classic case convergent evolution driven by shared environmental drivers, we lack full understanding whether timing and drivers diversification lineages are, fact, concordant. Here analyse time-calibrated phylogenetic reconstructions seven richest succulents, study dynamics relation abiotic variables....
Abstract Despite efforts for a complete phylogeny of Cactaceae, generic circumscription and species level relationships remain unsolved. Within Astrophytum one is assigned to different genus (Digitostigma) two are often treated as single (A. myriostigma A. coahuilense). endemic the Chihuahuan Desert, but may also be found in adjacent regions. We reconstructed date origin clades infer biogeographic patterns order understand between group members. Three sequences chloroplast DNA (rbcL gene,...
Plant functional traits are the result of natural selection to optimize carbon gain, leading a broad spectrum across environmental gradients. Among plant traits, leaf water storage capacity is paramount for drought resistance. We explored whether leaf-succulent taxa follow trait correlations similar those non-leaf-succulent evaluate both similarly constrained by relationships between and climate.
Abstract Our understanding of the complexity forces at play in rise major angiosperm lineages remains incomplete. The diversity and heterogeneous distribution most is so extraordinary that it confounds our ability to identify simple drivers diversification. Using machine learning combination with phylogenetic modelling, we show five separate abiotic biotic variables significantly contribute diversification Cactaceae. We reconstruct a comprehensive phylogeny, build dataset 39 variables,...
Abstract The succulent plant syndrome is defined by the coordination of traits that enhance internal water storage within tissues. Although distributed globally in different habitats, plants are thought to have evolved avoid drought arid regions, due trait modifications decrease tissue deficits. We evaluated evolution and ecological significance strategy at a global scale comparing climatic niche species displaying succulence core Caryophyllales with their non-succulent relatives. assembled...

The phenomenal expansion of angiosperms has prompted many investigations into the factors driving their diversification, but there remain significant gaps in our understanding flowering plant species diversity.
Abstract Many drivers of diversification have been identified across the angiosperm Tree Life, ranging from abiotic factors, such as climate change, to biotic factors key adaptations. While this provides invaluable evolutionary insight into rise major lineages, our understanding complexity underlying remains incomplete. In species-rich families Cactaceae, simple explanations triggers are insufficient. Their sheer morphological and ecological diversity, wide distribution heterogeneous...
