“…Seedlings were harvested after 4 weeks, and DNA samples were extracted following the modified CTAB miniprep protocols (Chan et al 2018). We used five microsatellite markers developed in Chan et al (2015) and Chan et al (2018) for multiplex genotyping, namely, BV05, BV03, BV54, BV28 and BV68.…”

Rare endemics usually have high risk of threats and extinction and often require conservation urgency. Hence, understanding the causes and consequences of rarity is the basis for sound conservation efforts. Here, we compare the reproductive fecundity, mating system, morphological traits, demography, microclimate and genetic diversity between a rare (Begonia herveyana) and a common (B. maxwelliana) herbaceous congener to investigate whether these attributes contribute to rarity in Begonia. The reproductive fecundity, mating system, microclimate and demographic structure of both species were similar and thus, did not explain well the causes of rarity. Both species recorded fruit sets of 55-67%, adopted a mixed-mating system with outcrossing rates of approximately 90%, established at microsites of high humidity and low light intensity, and showed a J-shaped demographic structure. However, both species differed in plant size and the level of genetic diversity. The plant size was bigger in B. maxwelliana and the genetic diversity of B. herveyana (H E = 0.113) was lower than that of B. maxwelliana (H E = 0.415). Rarity in B. herveyana could possibly be explained by the low level of genetic diversity, population decline and limited dispersal.

“…However, in their native environments, many Begonia species are rare and threatened by deforestation (Chan et al, 2015). Since Begonia genus is widespread in tropical regions of the world, its species have been used by local people as folk or traditional herbal medicines.…”

The present study was designed to evaluate the antibacterial property of crude extracts of the leaves of Begonia goegoensis N.E.Br. prepared in different solvent systems against Pseudomonas aeruginosa (ATCC 27583) and β-lactamases producing Pseudomonas aeruginosa (MBL-positive Pseudomonas aeruginosa) strains. Therefore, five kinds of solvents were used to extract the active ingredients from the leaves of Begonia goegoensis: ethanol, methanol, ethyl acetate, hexane, and dichloromethane. The testing of antibacterial activity of the plant extracts was carried out in vitro by Kirby-Bauer disc diffusion technique. Subsequently, the present study has shown that ethanolic extract from the leaves of Begonia goegoensis exhibited strong activity against Pseudomonas aeruginosa (inhibition zone diameter ranged from 12 mm to 13 mm), while methanolic leaf extract screened revealed less profound activity (within 11-12.5 mm). Moreover, it has been observed that ethyl acetate, hexane and dichloromethane extracts obtained from leaves of Begonia goegoensis revealed no antibacterial activity against P. aeruginosa and MBL-positive Pseudomonas aeruginosa strains. MBL-positive Pseudomonas aeruginosa was also susceptible to ethanolic and methanolic extracts (inhibition zone diameter ranged from 12.5 mm to 15.5 mm). Thus, the spectrum of activity observed in the present study indicate that the alcoholic leaf extract of Begonia goegoensis could be a possible source to obtain new and effective herbal medicines to treat various infectious diseases, including infections, caused by drug resistant microorganisms.

“…The genus Hillebrandia is classified as monotypic because it consists of only one specie Hillebrandia sandwicensis, a plant endemic of the Hawaiian Islands 3 . The species of the genus Begonia can be native or horticultural hybrids and are popular as houseplants due to the diversity in their floral form and leaf shape which adds commercial value to their species 4 . In Brazil there are about 213 Begonia species, mainly found in the Atlantic Forest, of which 186 are endemic 5,6 .…”

Species of the genus Begonia are expensive ornamental plants. There have been few reports of chemical studies with the Begonia species. Here we report the first chemical and biological study of essential oil for a species of Begonia. The essential oil of the Begonia reniformis leaf obtained by hydrodistillation was analyzed via GC-MS and twenty-one compounds were identified. Sesquiterpenes silphiperfol-4,7(14)-diene and β-vetispirene were the major ones with a percentage of 15.7 and 21.0%, respectively. The oil showed weak activity against bacteria Bacillus subtilis and Pseudomonas aeruginosa with minimum inhibitory concentrations of 625μg/mL for each of the two bacteria.
