Plant Strategies

Опубликована: Июль 27, 2023

Abstract Plants have evolved a remarkable array of adaptive solutions to the existential problem survival and reproduction in world where disturbances can be deadly, resources are scarce, competition is cutthroat. inherited phenotypic traits that increased their chance success, these indicators strategies for establishment survival. A plant strategy thought as “how species sustains population” (Westoby, 1998, p. 214) because all successful must positive demographic outcomes habitats which they adapted. This book aims articulate coherent framework studying unifies demography with functional ecology advance prediction ecology. Central this traits: heritable morphological, physiological, phenological attributes plants influence therefore drive fitness differences among species.

Genome evolution in plants and the origins of innovation

New Phytologist, Год журнала: 2023, Номер 240(6), С. 2204 - 2209

Опубликована: Сен. 2, 2023

Summary Plant evolution has been characterised by a series of major novelties in their vegetative and reproductive traits that have led to greater complexity. Underpinning this diversification the genome. When viewed at scale plant kingdom, genome punctuated conspicuous instances gene whole‐genome duplication, horizontal transfer extensive loss. The periods dynamic often coincide with key traits, demonstrating coevolution genomes phenotypes macroevolutionary scale. Conventionally, complexity diversity considered through lens duplication role loss remains comparatively unexplored. However, light reductive across multiple lineages, association between phenotypic warrants attention.

The extracellular matrix of green algae

PLANT PHYSIOLOGY, Год журнала: 2023, Номер 194(1), С. 15 - 32

Опубликована: Июль 3, 2023

Abstract Green algae display a wide range of extracellular matrix (ECM) components that include various types cell walls (CW), scales, crystalline glycoprotein coverings, hydrophobic compounds, and complex gels or mucilage. Recently, new information derived from genomic/transcriptomic screening, advanced biochemical analyses, immunocytochemical studies, ecophysiology has significantly enhanced refined our understanding the green algal ECM. In later diverging charophyte group algae, CW other ECM provide insight into evolution plants ways modulates during environmental stress. Chlorophytes produce diverse components, many which have been exploited for uses in medicine, food, biofuel production. This review highlights major advances studies algae.

Shifts in evolutionary lability underlie independent gains and losses of root-nodule symbiosis in a single clade of plants

Nature Communications, Год журнала: 2024, Номер 15(1)

Опубликована: Май 27, 2024

Abstract Root nodule symbiosis (RNS) is a complex trait that enables plants to access atmospheric nitrogen converted into usable forms through mutualistic relationship with soil bacteria. Pinpointing the evolutionary origins of RNS critical for understanding its genetic basis, but building this context complicated by data limitations and intermittent presence in single clade ca. 30,000 species flowering plants, i.e., nitrogen-fixing (NFC). We developed most extensive de novo phylogeny NFC an database reconstruct evolution RNS. Our analysis identifies rate heterogeneity associated two-step process: An ancestral precursor state transitioned more labile from which was rapidly gained at multiple points NFC. illustrate how process could explain independent gains losses RNS, contrary recent hypotheses suggesting one gain numerous losses, suggest broader phylogenetic scope may be required genome-phenome mapping.

Deep origin and gradual evolution of transporting tissues: Perspectives from across the land plants

PLANT PHYSIOLOGY, Год журнала: 2022, Номер 190(1), С. 85 - 99

Опубликована: Июль 29, 2022

Abstract The evolution of transporting tissues was an important innovation in terrestrial plants that allowed them to adapt almost all nonaquatic environments. These consist water-conducting cells and food-conducting bridge plant–soil plant–air interfaces over long distances. largest group land plants, representing about 95% known plant species, is associated with morphologically complex tissue a range additional traits. Therefore, this entire clade named tracheophytes, or vascular plants. However, some nonvascular possess conductive closely resemble their organization, structure, function. Recent molecular studies also point highly conserved toolbox regulators for tissues. Here, we reflect on the distinguishing features evolutionary history. Rather than sudden emergence complex, tissues, likely evolved gradually, building pre-existing developmental mechanisms genetic components. Improved knowledge intimate structure regulation across taxonomic breadth extant lineages, combined more comprehensive documentation fossil record required full understanding trajectory

Metagenome‐assembled genome of the glacier alga Ancylonema yields insights into the evolution of streptophyte life on ice and land

Summary Contemporary glaciers are inhabited by streptophyte algae that balance photosynthesis and growth with tolerance of low temperature, desiccation UV radiation. These same environmental challenges have been hypothesised as the driving force behind evolution land plants from algal ancestors in Cryogenian (720–635 million years ago). We sequenced, assembled analysed metagenome‐assembled genome glacier alga Ancylonema nordenskiöldii to investigate its adaptations life ice, whether this represents a vestige exaptations. Phylogenetic analysis confirms placement within sister lineage plants, Zygnematophyceae.

Two shifts in evolutionary lability underlie independent gains and losses of root-nodule symbiosis in a single clade of plants

bioRxiv (Cold Spring Harbor Laboratory), Год журнала: 2022, Номер unknown

Abstract Root nodule symbiosis (RNS) allows plants to access atmospheric nitrogen converted into usable forms through a mutualistic relationship with soil bacteria. RNS is complex trait requiring coordination from both the plant host and bacterial symbiont, pinpointing evolutionary origins of root nodules critical for understanding genetic basis RNS. This endeavor complicated by data limitations intermittent presence in single clade ca. 30,000 species flowering plants, i.e., nitrogen-fixing (NFC). We developed most extensive de novo phylogeny all major lineages NFC an enhanced database reconstruct evolution Through identification pathway gain, we show that shifts among heterogeneous rates can explain how such as arise many times across large phylogeny. Our analysis identifies two-step process which ancestral precursor state gave rise more labile was quickly gained at specific points NFC. rigorous reconstruction states illustrates could have led multiple independent gains losses RNS, contrary recent hypotheses invoking just gain numerous losses. may be example multi-level convergent evolution, thus broader phylogenetic scope genome-phenome mapping elucidate mechanisms enabling fully functional
