Abstract Population genomic analyses have demonstrated power to address major questions in evolutionary and molecular microbiology. Collecting populations of genomes is hindered many microbial species by the absence a cost effective practical method collect ample quantities sufficiently pure DNA for next-generation sequencing. Here we present simple amplify target complex, natural sample. The selective whole genome amplification (SWGA) technique amplifies using nucleotide sequence motifs...

ABSTRACT Vegetative phase change in Arabidopsis thaliana is mediated by a decrease the level of MIR156A and MIR156C, resulting an increase expression their targets, SQUAMOSA PROMOTER BINDING PROTEIN-LIKE (SPL) genes. Changes chromatin structure are required for downregulation but whether contributes to initial elevated unknown. We found that mutations components SWR1 complex (ARP6, SEF) genes encoding H2A.Z (HTA9 HTA11) reduce accelerate vegetative change, indicating promotes juvenile...

Age-dependent changes in plant defense against herbivores are widespread, but why these exist remains a mystery. We explored this question by examining suite of traits required for the interaction between swollen thorn acacias (genus Vachellia ) and ants genus Pseudomyrmex . In system, plants provide with refuge food form stipular spines, protein-lipid–rich “Beltian” bodies, sugar-secreting extrafloral nectaries—the “swollen syndrome.” show that syndrome develops at predictable time shoot...

Summary Plants transition through juvenile and adult phases of vegetative development in a process known as phase change (VPC). In poplars (genus Populus ) the differences between these stages are subtle, making it difficult to determine when this occurs. Previous studies VPC have relied on plants propagated vitro , leaving natural progression unknown. We examined developmental morphology seed‐grown derived tremula × alba (clone 717‐1B4), compared phenotype transgenics with manipulated...

Phenotypic plasticity--the capacity of a single genotype to produce different phenotypes in response varying environmental conditions--is widespread. Yet, whether, and how, plasticity impacts evolutionary diversification is unclear. According widely discussed hypothesis, promotes rapid evolution because genes expressed differentially across environments (i.e., with "biased" expression) experience relaxed genetic constraint thereby accumulate variation faster than do unbiased expression....

Ecological character displacement—trait evolution stemming from selection to lessen resource competition between species—is most often inferred a pattern in which species differ resource-use traits sympatry but not allopatry, and sympatric populations within each conspecific allopatric populations. Yet, without information on population history, the presence of divergent phenotype multiple does necessarily imply that there has been repeated displacement. Instead, such may arise if...

The genus Acacia is a large group of woody legumes containing an enormous amount morphological diversity in leaf shape. This at least part the result innovation development where many species are capable developing leaves both bifacial and unifacial morphologies. While not unique plant kingdom, unifaciality most commonly associated with monocots, its developmental genetic mechanisms have yet to be explored beyond this group. In study, we identify accession crassicarpa high regeneration rates...

Clonally propagated crops have long been recognized for their high levels of heterozygosity both between subgenomes within a somatic cell and cells an individual clone. Recent developments in read sequencing technologies accelerated our ability to identify this diversity it is increasingly clear that these sources are abundant clonal varieties can contribute variation traits interest breeders. In work, we assemble Mexican lime ( Citrus x aurantifolia ), interspecific hybrid C. hystrix var....
