“…This suggests that in weedy plants low inbreeding depression in seeds, resulting from autonomous autogamy, is to be expected in partially self-fertilized species (Charlesworth and Charlesworth, 1987). Similar results have been obtained from self-compatible Physalis angulata, whose low inbreeding depression index (δ = 0.27) makes self-pollination favorable (Carvalho et al, 2020). Although early emergence of cotyledons and leaves could provide an advantage for plant establishment in weedy plants, seedling germination and growth, reported in this study, occurred in a greenhouse under controlled conditions.…”

“…It has been reported that self-compatible individuals in cultivated plants of P. philadelphica (Pandey, 1957;Labate and Robertson, 2015) result from the S locus mutation (Mulato-Brito et al, 2007) causing an irreversible loss of the SI system (Igic et al, 2008). Instead, P. philadelphica has a labile reproductive system (self-and cross-fertilization) and may present a mixed system strategy, allowing fruit production by autogamy and allogamy (Carvalho et al, 2020). In small weedy populations of P. philadelphica, self-pollination would provide an advantage assuring some seed reproduction but under crop domestication artificial selection could favor SI individuals in the production of larger flowers and fruits.…”

“…The GSI system is characterized by late recognition of self-pollen tubes at the pistil. Pollen grains placed on stigmas by self-pollination germinate but the growth of pollen tubes is limited to the first third of pistil (Richards, 1997;Carvalho et al, 2020). It is known that the common ancestor of Physalis and Witheringia suffered a historical bottleneck that reduced S-allele diversity in three S-lineages, and its subsequent rapid diversification resulted in current species with a number of alleles similar to other Solanaceae genera (Igic et al, 2003).…”

Changes in Reproductive Traits in Physalis philadelphica; An Unexpected Shift Toward Self-Incompatibility in a Domesticated Annual Fruit Crop

Domestication is an evolutionary process with an impact on plant reproduction. Many domesticated plants are self-compatible (i.e., they lack mechanisms to reject their own pollen), but few domesticated plants are fully or partially self-incompatible. We used the husk tomato, Physalis philadelphica, as a study model to investigate changes in the reproductive strategy of an annual partially self-incompatible plant during the process of domestication. Wild and cultivated populations of this species coexist in close proximity. These different populations present a high level of morphological and genetic variation associated with different degrees of domestication. We hypothesized that artificial selection favors self-compatibility in cultivated plants through changes in their reproductive strategy and some reproductive parameters associated with domestication. To test this hypothesis, we characterized the floral morphology and some reproductive parameters of weedy plants (wild plants), landraces (semi-domesticated plant), and commercial plants (domesticated plants). We conducted an artificial crossing experiment, germinated the seeds, and recorded seedling growth. Commercial plants had the largest flowers and the highest number of ovules. Yet, they did not differ in other reproductive parameters (e.g., herkogamy, size of pollen grains, stigmatic area, and pollen:ovule ratio) from landraces and weedy plants. Physalis philadelphica produced fruits by autonomous autogamy in the artificial crossing experiment. These fruits were the smallest and lightest fruits at all degrees of domestication; however, fruit set of autonomous autogamy was higher in weedy plants. In addition, fruit production was higher when weedy plants donated pollen to commercial plants. Although seeds produced by autonomous autogamy of weedy plants had a low germination percentage, their cotyledons and the embryonic foliage leaves appeared earlier than in landraces and commercial plants. In conclusion, the domestication syndrome in this plant was manifested as increments in flower size and ovule production. Contrary to expectations, there was higher fruit production by autonomous autogamy in weedy plants than in cultivated plants. It seems that artificial selection in P. philadelphica favors self-incompatibility in cultivated plants. Nonetheless, spontaneous self-pollination seems to be advantageous in weedy populations because they produced viable seeds from which cotyledons and the embryonic foliage leaves emerged earlier than in cultivated plants.

“…In different countries of the world the fruits, roots and leaves of Physalis angulata L. are used in folk medicine as a treatment for various diseases (Salgado & Arana, 2013). The main secondary metabolites of Physalis angulata are withanolides, which are highly variable in chemical structure and exhibit interesting pharmacological activity (Ray & Gupta, 1994;Figueiredo et al, 2020;Sá et al, 2011;Pinto et al, 2016). The plant Physalis angulata is widespread in Uzbekistan and its reserves are sufficient for industrial use (Vasina et al, 1990).…”

The compounds (17S,20R,22R,24R,25S)-5β,6β:20,24-diepoxy-4β,25-dihydroxy-1-oxowith-2-en-26,22-olide and (20R,22R)-5α,14α,20-Trihydroxy-1-oxo-6α,7α-epoxywitha-2-enolide were isolated from a chloroform extract of the aerial parts of Physalis angulata L. (Solanaceae). Two products were isolated from the chromatographic separation extract. Compound I corresponds to physangulide B chloroform monosolvate, C28H38O7·CHCl3, while compound II is 14α-hydroxyixocarpanolide, C28H40O7. In the two molecular structures, the conformation of the steroid part (rings A, B, C, D) does not differ. In both crystals, molecules are linked by intermolecular O—H...O hydrogen bonds along the c-axis direction and form a two-dimensional network parallel to the ac plane. The absolute configuration was determined from X-ray diffraction data.

“…This is probably because these plants have the capacity for sexual reproduction through selfpollination. Based on an earlier study, it was known that Physalis species have an autogamous reproduction (P. angulata: Morales-Saavedra et al 2019;Figueiredo et al 2020;P. minima: Djakbé et al 2017).…”

Abstract. Sadiyah H, Ashari S, Waluyo B, Soegianto A. 2021. Genetic diversity and relationship of husk tomato (Physalis spp.) from East Java Province revealed by SSR markers. Biodiversitas 22: 184-192. This study aimed to investigate the genetic diversity and relationship of Physalis spp. from East Java province, Indonesia. A total of the 33 Physalis accessions was analyzed employing 16 SSR markers. AMOVA, UPGMA clustering, and non-parametric ANOVA analyses were applied. The results showed Genetic diversity in this sample showed lower levels (He =0.171), as compared to other studies of Physalis that used different molecular markers. The dendrogram revealed the presence of five groups, the different species belong to different small groups. The two major groups consist of accessions originated from eastern Java and Madura Island, indicating that there is no significant difference between accessions from both areas although there is geographic isolation in the form of the strait. It is consistent with the low population differentiation and high genetic drift. The AMOVA revealed that 96% of the total variation came from the within-population (among accession), reflect that the accessions used in this study have high variation and valuable for plant improvement through breeding programs. It is recommended that future evaluation studies include more accession from minor accessions detected in the sample of this study to better represent the genetic diversity available in this crop.
