A molecular phylogenetic investigation was undertaken for 30 species belonging to 15 genera of the palm family Arecaceae in Bangladesh to infer evolutionary relationships and molecular dating utilizing plastid-based matK and rbcL genes through multifaceted-algorithm driven approaches with Neighbor-Joining, Maximum-Likelihood, and Bayesian Inference methods. The study revealed that matK has better species discrimination efficiency than rbcL gene due to its highly variable nature. Transition/transversion bias test corroborated this finding as matK showed higher bias (2.632) than rbcL (2.235). Nucleotide substitution patterns were visualized via HYPERMUT program, which unveiled higher variability in matK and lower variability in rbcL alignment. Phylogenetic trees constructed with matK revealed monophyletic nature of origin for all the three subfamilies, viz. Arecoideae, Coryphoideae and Calamoideae, while rbcL trees exhibited polyphyly for Coryphoideae and monophyly for Arecoideae and Calamoideae. All the nine tribes belonging to three subfamilies demonstrated monophyletic nature in matK trees. Bootstrap support and Bayesian posterior probability were found to be higher in matK topologies than that of rbcL. The molecular clock test unraveled an equal evolutionary rate for matK and unequal rate for rbcL sequences. Molecular dating approach unveiled Calamoideae to be the most ancient subfamily (65.75 MYA) among the three subfamilies that originated during the Late Cretaceous period in the Mesozoic era, whereas Coryphoideae and Arecoideae were found to have originated in the Cenozoic era.

Porcini mushrooms (Boletus sect. Boletus) have both economic and ecological importance. During this study, a specimen of the phenotypically complex species Boletus himalayensis was analyzed morphologically and molecular genetically. This bolete speciesis characterized bya combination of porcini features: whitish pileus margin and context, pore surface and overall basidiomata having a whitish look before maturity and ithas a considerably longer stipe compared to the pileus diameter when immature, with whitish reticulation extending longitudinally towards base. The whitish context and the white to white yellowish pore surface both do not change color upon bruising. Although the specimen exhibited a long stipe and a small non−cracked pileus as compared to other collections of Boletus himalayensis, molecular genetic analysis revealed that it belongs to this species.

An ethnobotanical investigation was carried out in Gafargaon sub-district (upazila) under Mymensingh district, Bangladesh that unveiled a total of 79 medicinal plant species under 74 genera and 46 families which were used to treat various ailments through 106 formularies. In addition, molecular docking and dynamics simulation studies were performed based on ethnobotanical outcome for the first time in Bangladesh to unveil potential drug candidates. The study revealed that most of the species used for primary healthcare were herbs (44.3%) followed by trees (36.7%), shrubs (10.2%) and climbers (8.8%). Leaves were found to be the most frequently used part (34%) compared to other plant parts. Factor of informant consensus values ranged from 0.975 to 0.984 and the highest value was recorded for respiratory tract disorders (0.984). Maximum number of taxa was unraveled to treat digestive and gastrointestinal disorders. Fidelity level varied from 41.2 to 100%, where 11 species showed 100% fidelity, and the citation frequency was found above 70% for 15 different ailments. Molecular docking study exposed 60% Stephania japonica phytocompounds scoring higher than the control drug Ibuprofen (-7.0 kcal/mol) targeting rheumatoid arthritis. The phytocompounds Oxostephanine, Trilobine and Epistephanine were identified as lead drug candidates with binding affinity of -9.7, -8.7 and -8.6 kcal/mol, respectively. Molecular interactions of these compounds were found significant to identify potential drug surface hotspots. Molecular dynamics simulation shed light on regional flexibility profiles and unraveled notable structural stability of the top three phytocompounds. The present study would offer foundational data for identifying potential bioactive compounds that could be utilized in novel drug discovery efforts. Bangladesh J.

The present article deals with recording ethnomedicinal plants used by the people living in and around Dhaka city and also focuses on the plant species used during the pandemic to get relief from COVID-19. The information was gathered using open-ended and semi-structured questionnaires from 348 informants belonging to different classes of life. The survey has resulted in the recording of a total of 160 medicinal plant species belonging to 62 families and used for 157 ailments through 250 different formularies. Azadirachta indica A. Juss. was the most cited species in the study area. The highest factor informant consensus (FIC) was found in the Cuts and Wounds category, and Cynodon dactylon (L.) Pers. is the most cited species for this category. Acmella calva (DC.) R.K. Jansen was the culturally bound species attaining 100% Fidelity Level (FL) value. Among the ethnomedicinal plants, 40 species were found in the survey that were used by people to get relief from COVID-19. This interesting ethnomedicinal use is a new record for these 40 species. Most notable species are (Ocimum tenuiflorum L., Justicia adhatoda L., Centella asiatica (L.) Urban, Citrus aurantifolia (Christm. & Panzer) Swingle, Syzygium aromaticum (L.) Merr. & L.M. Perry, Mentha arvensis L., Zingiber officinale Rosc., Camellia sinensis (L.) O. Kuntze, and Nigella sativaL.Since ancient times, these species have been very popular and used to treat several ailments. The use of these species during the pandemic is a new hope to get relief from COVID-19 but this is very preliminary report. Further long-term study is needed to confirm the claim of these plants’ use against COVID-19.

The information was gathered using open-ended and semi-structured questionnaires from 348 informants belonging to different classes of life. The survey has resulted in the recording of a total of 160 medicinal plant species belonging to 62 families and used for 157 ailments through 250 different formularies. Azadirachta indica A. Juss. was the most cited species in the study area. The highest factor informant consensus (FIC) was found in the Cuts and Wounds category, and Cynodon dactylon (L.) Pers. is the most cited species for this category. Acmella calva (DC.) R.K. Jansen was the culturally bound species attaining 100% Fidelity Level (FL) value. Among the ethnomedicinal plants, 40 species were found in the survey that were used by people to get relief from COVID-19. This interesting ethnomedicinal use is a new record for these 40 species. Most notable species are (Ocimum tenuiflorum L., Justicia adhatoda L., Centella asiatica (L.) Urban, Citrus aurantifolia (Christm. & Panzer) Swingle, Syzygium aromaticum (L.) Merr. & L.M. Perry, Mentha arvensis L., Zingiber officinale Rosc., Camellia sinensis (L.) O. Kuntze, and Nigella sativaL.Since ancient times, these species have been very popular and used to treat several ailments. The use of these species during the pandemic is a new hope to get relief from COVID-19 but this is very preliminary report. Further long-term study is needed to confirm the claim of these plants’ use against COVID-19. Due to excessive use during COVID-19, these species are very rare in the habitats in and around Dhaka city. Conservation measures should be applied to save these species from extinction.\u0000Bangladesh J.
