The Brassicaceae is a large plant family (338 genera and 3,700 species) of major scientific economic importance. taxonomy this group has been plagued by convergent evolution in nearly every morphological feature used to define tribes genera. Phylogenetic analysis 746 nrDNA internal transcribed spacer (ITS) sequences, representing 24 the 25 currently recognized tribes, 146 genera, 461 species Brassicaceae, produced most comprehensive, single-locus–based phylogenetic published date. Novel...
Brassicaceae is an important family at both the agronomic and scientific level. The not only includes several model species, but it also becoming evolutionary However, resolving phylogenetic relationships within has been problematic, a large-scale molecular phylogeny in terms of generic sampling number genes still lacking. In particular, deeper family, for example between three major recognized lineages, prove particularly hard to resolve. Using slow-evolving mitochondrial marker (nad4...
The mustard family (Brassicaceae) is a scientifically and economically important family, containing the model plant Arabidopsis thaliana numerous crop species that feed billions worldwide. Despite its relevance, most phylogenetic trees of are incompletely sampled often contain poorly supported branches. Here, we present complete Brassicaceae genus-level phylogenies to date (Brassicaceae Tree Life or BrassiToL) based on nuclear (1,081 genes, 319 349 genera; 57 58 tribes) plastome (60 265 all...
Abstract In wide‐ranging species, the genetic consequences of range shifts in response to climate change during Pleistocene can be predicted differ among different parts distribution area. We used amplified fragment length polymorphism data compare structure Arabis alpina , a widespread arctic‐alpine and afro‐alpine plant, three distinct its range: North Atlantic region, which was recolonized after last ice age, European Alps, where were probably primarily altitudinal, high mountains East...
Abstract Arabis alpina is a characteristic plant in arctic‐alpine habitats and serves as classical example to demonstrate biology, ecology biogeography of disjuncts. It has wider distribution than most other plants, covering all European mountain systems, the Canary Islands, North Africa, high mountains East Africa Ethiopia, Arabian Peninsula ranges Central Asia Iran Iraq. Additionally it found northern amphi‐Atlantic area including northeastern America, Greenland, Iceland, Svalbard...
Abstract Mesopolyploid whole-genome duplication (WGD) was revealed in the ancestry of Australian Brassicaceae species with diploid-like chromosome numbers (n = 4 to 6). Multicolor comparative painting used reconstruct complete cytogenetic maps cryptic ancient polyploids. Cytogenetic analysis showed that karyotype Camelineae descended from eight ancestral chromosomes 8) through allopolyploid WGD followed by extensive reduction number. Nuclear and maternal gene phylogenies corroborated hybrid...
Significance Mechanisms of plant seed dormancy evolved to delay germination a season favorable for seedling growth. Germination timing is an important adaptive early-life history trait which determines fitness in natural and agricultural ecosystems. The DELAY OF GERMINATION 1 ( DOG1 ) gene provides genetic variation dormancy, was the first dormancy-specific cloned, encodes protein unknown function. We show here that controls different species by setting optimal ambient temperature window...
The Brassicaceae family (mustards or crucifers) includes Arabidopsis thaliana as one of the most important model species in plant biology and a number crop plants such various Brassica (e.g. cabbage, canola mustard). Moreover, comprises an increasing that serve study systems many fields science evolutionary research. However, systematics taxonomy are very complex access to scientifically valuable reliable information linked genus names its interpretation often difficult. BrassiBase is...
Abstract Angiosperms have become the dominant terrestrial plant group by diversifying for ~145 million years into a broad range of environments. During course evolution, numerous morphological innovations arose, often preceded whole genome duplications (WGD). The mustard family (Brassicaceae), successful angiosperm clade with ~4000 species, has been many evolutionary lineages more than 30 years. Here we develop species inventory, analyze variation, and present maternal, plastome-based...
Based on recent achievements in phylogenetic studies of the Brassicaceae, a novel infrafamilial classification is proposed that includes major improvements at subfamilial and supertribal levels. Herein, family subdivided into two subfamilies, Aethionemoideae (subfam. nov.) Brassicoideae. The Brassicoideae, with 57 58 tribes are further partitioned five supertribes, including previously recognized Brassicodae newly established Arabodae, Camelinodae, Heliophilodae, Hesperodae. Additional...
The biomechanical, morphological and ecophysiological properties of plant seed/fruit structures are adaptations that support survival in unpredictable environments. High phenotypic variability noxious invasive weed species such as Raphanus raphanistrum (wild radish) allow diversification into new environmental niches. Dry indehiscent fruits (thick lignified pericarp [fruit coat] enclosing seeds) have evolved many times independently. Here, we demonstrate the hard (Brassicaceae) imposes...

Insertions/deletions ≥3 bp (base pairs) provided reliable information whereas indels ≤2 bp, probably originating from slipped‐strand mispairing, are prone parallelism in context our framework.

Lepidium sensu stricto (s.s.) (Brassicaceae) (ca. 150 species) is distributed worldwide with endemic species on every continent. It represented in Australia and New Zealand by 19 seven native species, respectively. In the present study we used a nuclear ribosomal internal transcribed spacer (ITS) phylogeny comparison cpDNA to unravel origin of Australian/New species. Although phylogenetic relationships within s.s. were not fully resolved, data agreement Californian from Australia/New...
ABSTRACT The Brassicaceae family is of great scientific interest because it contains the plant model organism Arabidopsis thaliana. Currently, contemporary research activities expand to other taxa. Despite that, phylogeny this only partly understood. present study deepens our understanding a family‐wide by using two new approaches in phylogenetic research. We used molecular marker from mitochondrial genome and utilised relaxed dating method. Our data generally confirms recent tribal...

ALCATRAZ ( ALC ), INDEHISCENT IND SHATTERPROOF 1 SHP ) and 2 are known fruit genes A rabidopsis thaliana that expressed valve margin governing dehiscence zone formation.

Understanding how plants cope with changing habitats is a timely and important topic in plant research. Phenotypic plasticity describes the capability of genotype to produce different phenotypes when exposed environmental conditions. In contrast, constant production set distinct by one mediates bet hedging, strategy that reduces temporal variance fitness at expense lowered arithmetic mean fitness. Both phenomena are thought represent adaptation strategies unstable environments. However,...
Systematics of the genus Thlaspi s.l. is difficult and controversial. Previous hypotheses have been based on morphological anatomical data. We analyzed sequence variation internal transcribed spacer (ITS) regions nuclear ribosomal DNA (nrDNA) among 13 taxa, representing all sections genus. Phylogenetic relationships ITS sequences taxa studied are in general concordance with a previously published chloroplast phylogeny this group. Most-parsimonious trees from data support three groups that...
