Integrating developmental and macroevolutionary approaches reveals a staminodial origin of all alternisepalous organs in Caryophyllaceae

American Journal of Botany, EarlyView.
Abstract Premise The identity of sterile floral organs in second‐whorl, alternisepalous positions within Caryophyllaceae remains contentious, having been described as staminodes, “petaloids,” or petals homologous with those of other Pentapetalae. Limited ingroup and outgroup sampling and floral developmental data and inadequate phylogenetic comparative

Soil Silicon Application Alleviates Drought Stress in Sugar Beet (Beta vulgaris L.)

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background: The increasing frequency and intensity of drought events have led to yield and quality losses in sugar beet production in temperate regions in Central Europe. Under arid conditions, silicon (Si) application reduced beet yield losses under drought. Similar data for temperate climates are missing.

Convergent evolution of betalains in Caryophyllales

, 2023
In this thesis, I investigate the evolution of betalains in Caryophyllales. Betalains are a group of red and yellow pigments, which in plants occur only in the order Caryophyllales. Here, betalains replace the otherwise ubiquitous anthocyanin pigments, and the two pigment types appear mutually exclusive.

Portulaca abscondita (Portulacaceae, Caryophyllales), a new microendemic species from Monte Azul, Minas Gerais, Brazil

Nordic Journal of Botany, EarlyView.
Portulaca (Portulacaceae) is a cosmopolitan genus with centers of diversity in Africa and South America. In Brazil, 22 species are recognized, most occurring in xerophytic environments of the Cerrado, particularly in Campos Rupestres. These rocky montane habitats, especially in northern Minas Gerais state, remain undercollected despite their high ...

Two new endemic species of Portulaca (Portulacaceae) from the Brazilian Pampa grasslands

Nordic Journal of Botany, EarlyView.
Portulaca L. is a monophyletic, cosmopolitan genus of succulent plants comprising ca 153 species, with particularly high diversity in xerophytic ecosystems in tropical and subtropical regions. Based on morphological evidence, we describe and illustrate two new species from the Brazilian Pampa, Portulaca guaritensis and Portulaca guenoa.

Evolutionary framework and tribal circumscription of Amaranthaceae sensu stricto based on a comprehensive phylogenomic analysis

Cladistics, EarlyView.
Abstract The evolutionary history of Amaranthaceae sensu stricto (s.s.) has been shaped by multiple whole‐genome duplications and rapid radiations, producing an ecologically diverse lineage whose internal relationships have long remained unresolved.

Better Control With More Food: Continuous Provision of Alternative Food Enhances Thrips Control by Predatory Mites

Journal of Applied Entomology, EarlyView.
ABSTRACT The use of alternative food has become an integral component of biocontrol, allowing the introduction and establishment of predators into a crop before pest invasion and sustaining populations even when pest densities are low. The addition of alternative food also has a positive long‐term effect in decreasing the densities of the pest.
