Butterflies and moths (Lepidoptera) are one of the major superradiations insects, comprising nearly 160,000 described extant species. As herbivores, pollinators, prey, Lepidoptera play a fundamental role in almost every terrestrial ecosystem. also indicators environmental change serve as models for research on mimicry genetics. They have been central to development coevolutionary hypotheses, such butterflies with flowering plants moths’ evolutionary arms race echolocating bats. However, these hypotheses not rigorously tested, because robust lepidopteran phylogeny timing novelties lacking. To address issues, we inferred comprehensive Lepidoptera, using largest dataset assembled order (2,098 orthologous protein-coding genes from transcriptomes 186 species, representing all superfamilies), dated it carefully evaluated synapomorphy-based fossils. The oldest members crown group appeared Late Carboniferous (∼300 Ma) fed nonvascular land plants. evolved tube-like proboscis Middle Triassic (∼241 Ma), which allowed them acquire nectar This morphological innovation, along other traits, likely promoted extraordinary diversification superfamily-level groups. ancestor was nocturnal, our results indicate that became day-flying Cretaceous (∼98 Ma). Moth hearing organs arose multiple times before between bats, perhaps initially detecting wide range sound frequencies being co-opted specifically detect bat sonar. Our study provides an essential framework future comparative studies butterfly moth evolution.

The Angiosperm Terrestrial Revolution and the origins of modern biodiversity

New Phytologist, Journal Year: 2021, Volume and Issue: 233(5), P. 2017 - 2035

Summary Biodiversity today has the unusual property that 85% of plant and animal species live on land rather than in sea, half these tropical rainforests. An explosive boost to terrestrial diversity occurred from c . 100–50 million years ago, Late Cretaceous early Palaeogene. During this interval, Earth‐life system was reset, biosphere expanded a new level productivity, enhancing capacity environments. This biodiversity coincided with innovations flowering biology evolutionary ecology, including their flowers efficiencies reproduction; coevolution animals, especially pollinators herbivores; photosynthetic capacities; adaptability; ability modify habitats. The rise angiosperms triggered macroecological revolution drove modern secular, prolonged shift new, high levels, series processes we name here Angiosperm Terrestrial Revolution.

Synthesizing trait observations and knowledge across the Tree of Life remains a grand challenge for biodiversity science. Species traits are widely used in ecological evolutionary science, new data methods have proliferated rapidly.

The tree of life is the fundamental biological roadmap for navigating evolution and properties on Earth, yet remains largely unknown. Even angiosperms (flowering plants) are fraught with data gaps, despite their critical role in sustaining terrestrial life. Today, high-throughput sequencing promises to significantly deepen our understanding evolutionary relationships.

The chromosome-scale reference genome of black pepper provides insight into piperine biosynthesis

Nature Communications, Journal Year: 2019, Volume and Issue: 10(1)

Published: Oct. 16, 2019

Abstract Black pepper ( Piper nigrum ), dubbed the ‘King of Spices’ and ‘Black Gold’, is one most widely used spices. Here, we present its reference genome assembly by integrating PacBio, 10x Chromium, BioNano DLS optical mapping, Hi-C mapping technologies. The 761.2 Mb sequences (45 scaffolds with an N50 29.8 Mb) are assembled into 26 pseudochromosomes. A phylogenomic analysis representative plant genomes places magnoliids as sister to monocots-eudicots clade indicates that black has diverged from shared Laurales-Magnoliales lineage approximately 180 million years ago. Comparative genomic analyses reveal specific gene expansions in glycosyltransferase, cytochrome P450, shikimate hydroxycinnamoyl transferase, lysine decarboxylase, acyltransferase families. transcriptomic disclose berry-specific upregulated expression genes each these These data provide evolutionary perspective shed light on metabolic processes relevant molecular basis species-specific piperine biosynthesis.

Pollination syndromes, recurring suites of floral traits appearing in connection with specific functional pollinator groups, have served for decades to organise diversity under a functional-ecological perspective.

Insect pollination for most of angiosperm evolutionary history

New Phytologist, Journal Year: 2023, Volume and Issue: 240(2), P. 880 - 891

Most contemporary angiosperms (flowering plants) are insect pollinated, but pollination by wind, water or vertebrates occurs in many lineages. Though evidence suggests may be ancestral angiosperms, this is yet to assessed across the full phylogeny. Here, we reconstruct mode of and quantify timing environmental associations shifts. We use a robust, dated phylogeny species-level sampling all angiosperm families model evolution modes. Data on system syndrome 1160 species were collated from primary literature. Angiosperms ancestrally insects have pollinated for c. 86% evolutionary history. Wind evolved at least 42 times, with few reversals animal pollination. Transitions between vertebrate more frequent: 39 times an insect-pollinated ancestor 26 reversals. The probability wind increases habitat openness (measured Leaf Area Index) distance equator.

The angiosperm radiation played a dual role in the diversification of insects and insect pollinators

Nature Communications, Journal Year: 2024, Volume and Issue: 15(1)

Published: Jan. 22, 2024

Interactions with angiosperms have been hypothesised to play a crucial role in driving diversification among insects, particular emphasis on pollinator insects. However, support for coevolutionary insect-plant interactions is weak. Macroevolutionary studies of insect and plant diversities the hypothesis that diversified after peak diversity Early Cretaceous. Here, we used family-level fossil record insects as whole, families particular, estimate rates macroevolutionary history using Bayesian process-based approach. We found played dual changed through time, mitigating extinction Cretaceous promoting origination Cenozoic, which also recovered only. Although pollinated gymnosperms before angiosperm radiation, radiation new lineages began increased, particularly significant 50 Ma. global temperature, increases diversity, spore plants were strongly correlated rates, suggesting multiple drivers influenced arguing investigation different explanatory variables further studies.

Asterid Phylogenomics/Phylotranscriptomics Uncover Morphological Evolutionary Histories and Support Phylogenetic Placement for Numerous Whole-Genome Duplications

Molecular Biology and Evolution, Journal Year: 2020, Volume and Issue: 37(11), P. 3188 - 3210

Published: June 26, 2020

Abstract Asterids are one of the most successful angiosperm lineages, exhibiting extensive morphological diversity and including a number important crops. Despite their biological prominence value to humans, deep asterid phylogeny has not been fully resolved, evolutionary landscape underlying radiation remains unknown. To resolve phylogeny, we sequenced 213 transcriptomes/genomes combined them with other data sets, representing all accepted orders nearly families asterids. We show supported monophyly asterids, Berberidopsidales as sister except Icacinales, Aquifoliales, Bruniales, Icacinaceae Ehretiaceae. Novel taxon placements benefited from expanded sampling living collections botanical gardens, resolving hitherto uncertain relationships. The remaining ambiguous here likely due limited could be addressed in future relevant additional taxa. Using our well-resolved reference, divergence time estimates support an Aptian (Early Cretaceous) origin asterids before Cretaceous–Paleogene boundary. Ancestral state reconstruction at family level suggests that ancestor was woody terrestrial plant simple leaves, bisexual, actinomorphic flowers free petals anthers, superior ovary style, drupaceous fruits. Whole-genome duplication (WGD) analyses provide strong evidence for 33 WGDs Berberidopsidales, four suprafamilial seven familial/subfamilial WGDs. Our results advance understanding numerous novel insights into diversification evolution.
