The aim of this research was to evaluate the phytochemical profiles of flour from red, yellow and green fruits of Capsicum pubescens (commun name: locoto) and compare with “locoto” commercial powder (Lcp). Soluble protein (SP), total sugar (TS), free phenolic compounds (FPC), ascorbic acid (AA), total monomeric anthocyanin (TMA), condensed and hydrolizable tannin (CT, HT) and carotenoids (C) were determined by spectrophotometric methods. Multielemental composition by ICP-MS was also done. The flour showed low amounts of calories and high potassium and low sodium levels. Flour from “locoto” fruits contained mainly carotenoids (0.82 to 20 g Eβ-C/100g DW), polyphenolic compounds (681 - 822 mg GAE/100g DW) and ascorbic acid (100 - 199 mg AA/100g DW). The polyphenolic profile of Lcp was similar to flour obtained in our laboratory but the level of carotenoid was lower than that of flour. The fiber content of flour was around 3% in all cases. All preparations obtained from flour and Lcp showed antioxidant activity with SC50 values between 1.4 and 3 μg GAE/mL. Inhibitory capacity on Lipo-oxygenase enzyme was also demonstrated. Non mutagenic effect was detected. The “locoto” flour showed nutraceutical characteristics that are demanded by functional food and could be used as a dietary supplement.

An evaluation of the incidence of Crypticerya multicicatrices and Maconellicoccus hirsutus in Colombian Seaflower Biosphere Reserve in San Andrés, Providence and Santa Catalina islands, from mid-August to mid-November 2012 was made. 38 locations were sampled, and 34% of sites tested show an incidence of C. multicicatrices oscillating between a range of 80%-100%, 24% with 40%-80% of incidence, 18% between 10%-40% and 24% with a range of 0%-10%. The occurrence of M. hirsutus fluctuated between 0.5% and 17%. There were seven genera of ants associated C. multicicatrices and 94 hosts of this agriculturally important insect and we found high incidence of associated sooty mold in C. multicicatrices hosts. Observations also contained some developmental stages of C. multicatrices.

Whole-genome duplications(WGDs)are regarded as important drivers of macroevolution in plants(Clark and Donoghue,2018).However,there are few studies that test a connection between WGDs and evolutionary *** proper study of evolutionary patterns related to WGDs needs a well-resolved phylogeny,accurate dates of the WGD events,and historical reconstructions of the evolutionary novelties(Clark and Donoghue,2018).The advent of exhaustive phylogenomic studies is becoming a promising way to solve these issues,as wholegenome data can help clarify obscure phylogenetic relationships,evaluate patterns associated with WGDs,and track down the evolution of life-history traits that shaped plant lineages(Bellot et al.,2020).

In this work, the localization, density, morphology and ultrastructure of secretory structures in aerial organs of Flourensia campestris (FC) and F. oolepis (FO) (Asteraceae) by means of a combination of light, fluorescence, transmission (TEM) and scanning electron microscopy (SEM) were examined. The possible role of secretory structures in the production and secretion of the phytotoxic sesquiterpene (-)-hamanasic acid A ((-)HAA) in both species was also assessed. Capitate glandular trichomes were found in all reproductive organs of FC and FO, and were being reported for the first time. These glandular trichomes, typically associated to edges and veins, were of the same type as those already described for vegetative organs, and were abundant in involucral bracts and corolla of tubulose and ligulate flowers. Their density in reproductive organs of both species was similar (ca. 30/mm2) and lower than that found in leaves (ca. 100/mm2) and stems (ca. 160/mm2 in FC, and up to 650/mm2 in FO). Glandular trichomes in vegetative organs followed a species-specific pattern of distribution. TEM and SEM observations suggest that each species differs in the way in which secretory materials are released to the outside: through cracks or pores in FC, or through a loose cuticle in FO. Similar inspections of the secretory ducts revealed lipophilic vacuoles localized in subepithelial and epithelial cells, in which secretions accumulated before being transferred to the duct. The presence of wall ingrowths in subepithelial cells suggests that granulocrine secretion operates in these species. Secretory ducts varied in density and diameter among the organs in both species, with the combination being maximal in woody stems. (-)HAA was only detected in surface secreted resins of both species, and its concentration (2D-TLC, GC-FID) was intimately associated with the distribution and density of glandular trichomes in each organ (capitula, leaves, and stems with primary or secondary growth).
