Transcriptome mining of squalene cyclases in Lygodium japonicum

The effects of 2,4-dichlorophenoxyacetic acid (2,4-D), gibberellic acid (GA), and abscisic acid (ABA) on the morphogenesis of gametophytes of Lygodium japonicum growing as longer-than-broad biplanar plates in red light and as broader-than-long biplanar plates in blue light were studied. Addition of 2,4-D or GA to the medium induced a change in the form of gametophytes from biplanar to filamentous in red light. Gametophytes growing in a medium containing 2,4-D in blue light were longer than broad, very much like gametophytes growing in the basal medium in red light. Although ABA generally retarded the growth of gametophytes in both light regimes, its presence in a medium containing 2,4-D nullified the effect of the latter, causing gametophytes to become plate-like in red light and short and stunted in blue light. Changes in the morphology of gametophytes induced by growth hormones were accompanied by corresponding changes in their length:width ratio and cell number.

Lygodium Japonicum

Oral Collection and documentation of indigenous knowledge of local people have an important role in scientific research, biodiversity conservation, and the drug development process. A study was carried out to document the medicinal plants that have been used by the local folk healer to treat Shingles in Ilam district, Eastern Nepal. A renowned folk healer who was involved in curing Shingles for decades and 30 key informants were selected for the interview to know the methods of curing Shingles. Altogether six plants viz: Oroxylum indicum, Cynodon dactylon, Centella asiatica, Drymaria cordata, Sesamum indicum, and Lygodium japonicum were found to be used against the disease. The traditional method of preparing medicine from these plants was found to be highly effective. The finding provides a clue for further extensive lab-based research to isolate the specific compounds that are effective against the disease.
