“…Although annual/self‐incompatible species are not known to be present in the genus, the other combinations of mating system and life history are well represented (annual/self‐compatible, perennial/self‐compatible, and perennial/self‐incompatible). The 14 species selected were P. acutifolia , P. angulata , P. coztomatl , P. crassifolia , P. lagascae , P. longifolia , P. minima , P. peruviana , P. philadelphica , P. pruinosa , P. pubescens , P. viscosa , P. walteri , and Alkekengi officinarum (previously named Physalis alkekengi , Pretz and Deanna, 2020) (Appendix S1).…”

Premise Plant defenses are shaped by many factors, including herbivory, lifespan, and mating system. Predictions about plant defense and resistance are often based on resource allocation trade‐offs with plant growth and reproduction. Additionally, two types of plant resistance, constitutive and induced resistance, are predicted to be evolutionary alternatives or redundant strategies. Given the variety of plant trait combinations and non‐mutually exclusive predictions, examining resistance strategies in related species with different combinations of growth and reproductive traits is important to tease apart roles of plant traits and evolutionary history on plant resistance. Methods Phylogenetic comparative methods were used to examine the potentially interacting influences of life history (annual/perennial), mating system (self‐compatible/self‐incompatible), and species growth rates on constitutive resistance and inducibility (additional resistance following damage) across Physalis species (Solanaceae). Results Resistance was evolutionarily labile, and there was no correlation between constitutive resistance and inducibility. Annual species with fast growth rates displayed higher constitutive resistance, but growth rate did not affect constitutive resistance in perennials. In contrast, inducibility was negatively associated with species growth rate regardless of life history or mating system. Conclusions The different effects of plant life history and growth rate on constitutive resistance and inducibility indicate that defensive evolution is unconstrained by a trade‐off between resistance types. The interactions among plant life history, growth, and herbivore resistance show that plant defense is shaped not only by herbivore environment, but also by plant traits that reflect a plant's evolutionary history and local selective pressures.

We continue the inventory of alien vascular plants of Kyrgyzstan, with emphasis on the time and pathways of introduction of the species and their current status in the territory. Each taxon is discussed in the context of plant invasions in Central Asia. This work is a further development of the preliminary checklist of alien plants of Kyrgyzstan, which was compiled for the Global Register of Introduced and Invasive Species in 2018. This contribution includes all alien species of Kyrgyzstan belonging to Solanaceae and Asphodelaceae and one species of Asteraceae. Physalis philadelphicus (syn. P. ixocarpa) is reported for the first time from Central Asia, as new to Kazakhstan, Kyrgyzstan and Uzbekistan, thus marking a recent invasion with a variety of imported grain and seed material. The old records of P. ixocarpa from Uzbekistan are based on misidentified specimens of P. angulata. Physalis angulata is an old cotton immigrant in Central Asia, whose invasion started in the 1920s; it is excluded from the alien flora of Kyrgyzstan as registered in error on the basis of cultivated plants. Alkekengi officinarum is an archaeophyte of the Neolithic period in Central Asia, formerly used for food, now strongly declining and largely casual in Kyrgyzstan. The only historical record of Physalis viscosa from Uzbekistan was based on a technical error and belongs to A. officinarum. Datura stramonium and Hyoscyamus niger were introduced as medicinal plants during the period of the Arabic invasion of Central Asia, by the 11th century. Datura innoxia is a newly recorded casual alien, recently escaped from ornamental cultivation. Nicandra physalodes is a casual alien, which was cultivated by Russian colonists in the early 20th century for culinary use and is currently used in ornamental cultivation. Hemerocallis fulva was a remnant of historical cultivation in the former Khanate of Buxoro, and its formerly established colonies are presumably extinct in the wild. Bidens frondosa was seemingly introduced with contaminated forage and seed of American origin during the late Soviet period and started to spread in the period of independence; its invasion in the former USSR is analysed.

“…The genus includes ornamental and orphan crops such as Chinese lantern ( P. alkekengi ), tomatillo ( P. philadelphica and P. ixocarpa ), goldenberry ( P. peruviana ), and groundcherry ( P. grisea and P. pruinosa ), and many other species yielding edible fruits. Physalis also occupies a key phylogenetic position that complements other Solanaceae models and captures the largest species richness in the tribe Physalideae, which itself has the highest diversity of Solanaceae genera (Deanna et al, 2019; Pretz & Deanna, 2020; Zamora-Tavares et al, 2016) . Moreover, Physalis species show substantial variation in developmental and molecular traits, including inflorescence complexity, secondary metabolism, and disease resistance (Baumann & Meier, 1993; Huang et al, 2020; Park et al, 2014; Whitson, 2012; W.-N. Zhang & Tong, 2016).…”

The highly diverse Solanaceae family contains several widely studied model and crop species. Fully exploring, appreciating, and exploiting this diversity requires additional model systems. Particularly promising are orphan fruit crops in the genus Physalis, which occupy a key evolutionary position in the Solanaceae and capture understudied variation in traits such as inflorescence complexity, fruit ripening and metabolites, disease and insect resistance, self-compatibility, and most notable, the striking Inflated Calyx Syndrome (ICS), an evolutionary novelty found across angiosperms where sepals grow exceptionally large to encapsulate fruits in a protective husk. We recently developed transformation and genome editing in Physalis grisea (groundcherry). However, to systematically explore and unlock the potential of this and related Physalis as genetic systems, high-quality genome assemblies are needed. Here, we present chromosome-scale references for P. grisea and its close relative P. pruinosa and use these resources to study natural and engineered variation in floral traits. We first rapidly identified a natural structural variant in a bHLH gene that causes petal color variation. Further, and against expectations, we found that CRISPR-Cas9 targeted mutagenesis of 11 MADS-box genes, including purported essential regulators of ICS, had no effect on inflation. In a forward genetics screen, we identified huskless, which lacks ICS due to mutation of an AP2-like gene that causes sepals and petals to merge into a single whorl of mixed identity. These resources and findings elevate Physalis to a new Solanaceae model system, and establish a new paradigm for the search of factors driving ICS.
