Abstract: Medicinal plants have been proven crucial for the treatment of several ailments. Despite the advent of modern medicines, majority of the global populations continue
to rely on plant-based medicines for addressing primary healthcare needs in the rural localities. The different ethnic tribes of Arunachal Pradesh are reported to be a rich repository of
ethnomedicinal knowledge and traditional healthcare practices. The indigenous medicinal knowledge system prevalent among the tribal communities could play a pivotal role in discovery of novel
phytotherapeutic compounds effective against diabetes and hypertension. This systematic review aimed at identifying the medicinal plants used by the tribes of Arunachal Pradesh for the treatment of
diabetes and hypertension. Present review analysed the data of 17 ethnobotanical papers published on 9 tribes of Arunachal Pradesh and shortlisted medicinal plants used for the treatment of diabetes
and hypertension. Analysis revealed 16 medicinal plant species against hypertension and 44 medicinal plant species against diabetes used by the ethnic communities of Arunachal Pradesh. The highest
cultural importance index value of 0.75 was recorded for Clerodendrum colebrookeanum Walp. which is used by the Adi, Apatani, Galo, Nyishi and Tagin communities. One way analysis of variation revealed
significant variation in medicinal plants use with a P-value of 0.02 and F-value of 2.33. Among the 44 medicinal plant species reported against diabetes, the highest cultural importance index value
was recorded for Solanum americanum Mill. (0.20) used by Adi, Galo, Nyishi and Tagin tribe. The present analysis results suggested for detailed phytochemistry and pharmacological investigation to
unveil the therapeutic potential of the selected medicinal plants reported to be traditionally used against diabetes and hypertension.

Abstract: The Rabha community of Assam is known to have a close association with nature since time immemorial. They mostly dwell in the periphery of forests and utilize natural resources in the form of various provisioning services such as food,
fuel, medicine etc. Locally available vegetation is an integral part of their regular diet and traditional dishes. Although extensive studies on wild edible plants (WEPs) consumed by various tribes
from different parts of the state have been previously accomplished by several authors, there is a meagre information on the WEPs consumed by the Rabha community. The present study documented WEPs
from the selected region of Rabha in Goalpara district of Assam, based on standard ethnobotanical field method and literature review. The study recorded 51 species of WEP belonging to 45 genera
and 30 families. Plant parts such as fruit, leaf, seed, tuber, flower, rhizome, shoot, stem, root or the entire plant are consumed. The most widely consumed plant parts harvested were noted to
be fruit (17 species) and the least was stem and frond (1/each). WEPs are consumed in different modes such as vegetables, fruits and other forms such as spices, condiments, nuts etc.
The plants are mainly consumed either cooked (55%) or raw (14%), while others are traditionally processed (10%). A few species (2-10%) had a bi or tri-modal form of consumption. The findings emphasized
the significance of reinforcement to food security and conservation of the plant-based knowledge of the Rabha community for ensuring a sustainable diet source from the wild botanicals.

Abstract: TPhaius tankervilleae (Banks) Blume is a terrestrial sympodial orchid native to Arunachal Pradesh. It thrives
in dense moist tropical forests at altitudes ranging from 1000 to 2000 meters. The orchid holds economic significance in floriculture, natural dye production,
and traditional medicine. However, it faces threats to its survival due to various anthropogenic activities, and low seed germination (only 5%) in natural conditions.
In the present study, we aimed to formulate a suitable medium for the micropropagation of this orchid. Our findings revealed that for in vitro asymbiotic seed
germination, protocorm formation, and seedling development, both full strength and ½ strength Murashige and Skoog (MS) were better basal media in comparison
to ¼ strength MS, Knudson C, Vacin and Went, and Heller medium, although embryo swelling occurred after 7 weeks of culture (WOC) on all of them. Among the
organic additives screened for media supplementation, peptone emerged as a superior option compared to coconut water or yeast extract on whose supplementation
at 2 g/l into both full MS and ½ MS media resulted in early embryo swelling (4 WOC), along with high seed germination (51.5%) and protocorm formation (44.7%)
after 10 WOC.

Abstract: The sundried biomass of Mimosa pudica L. (Fabaceae) was applied as organic nitrogen supplementing material (MP) @3:1 along with basal substrate,
paddy straw (PS+MP) on dry weight basis for cultivation of four popular commercial species of oyster mushrooms viz: Pleurotus sajor-caju, P.sapidus, P. flabellatus and P. citrinopileatus to
determine its effect on the biological efficiency of mushroom mycelia, its ability to efficiently utilize the basal substrate and mushroom yields. The study was conducted for three different
growing months, viz: November, January and March in an outdoor, semi-technical mushroom house at Rajiv Gandhi University, Arunachal Pradesh. Paddy straw (PS) was used as the control substrate.
Each treatment was kept with 5 replicates (n=5). Inoculation of ready substrates was done using 2-3 weeks old whole wheat grain spawn @3% by layering method. From the study, the mean biological
efficiency (BE) value for all species of Pleurotus on supplemented substrates (PS+MP) was recorded at 103.1% which was significantly higher than the BE of 94.2% on untreated substrate paddy
straw (PS). Also, a comparatively higher mushroom yield (fresh weight) was recorded from supplemented substrates over unsupplemented substrate paddy straw. The results indicate that
supplementing the basal substrate paddy straw with M. pudica@3:1 is a better substrate giving enhanced biological efficiency and best mushroom yields (p<0.001) on these species of
oyster mushrooms.

Abstract: Edible flowers have been reported to play a significant role in human sustenance throughout history, serving multiple purposes such as culinary use,
ornamental value, medicinal applications, decorative arrangements, essential oil production, nutraceutical support and being utilized in various religious rituals. This study aims to create a
comprehensive record of the traditional use of edible flowers by the indigenous tribal communities residing in Kohima district of Nagaland, India. Traditional knowledge of plants holds immense
importance in local culture and belief systems of various ethnic groups worldwide and preserving this knowledge system in written form is crucial given the rapid erosion of plant based traditional
knowledge in recent decades. The present research documents flower bearing edible plants of Kohima district of Nagaland, and providing valuable insights into their medicinal significance. A total
of 51 edible flower bearing species from 22 different plant families were documented through random interview and focused group discussions with traditional practitioners, field guides and local
village elders. Plants samples collected were identified using online literatures, regional floras, monographs and other botanical references. Notably, the plant families with highest number of
edible flowers bearing species were documented from Amaryllidaceae, Zingiberaceae, Brassicaceae and Apiaceae. Present findings have provided valuable insights into edible flowers and phytochemical
studies could unveil some important compounds of medicinal and nutraceutical significance.

Abstract: Cellulose, a major component of the most abundant lignocellulosic biomass on the Earth, can be broken down by the enzyme cellulases into
simple sugars, which can then be converted into biofuel and other value-added products. Cellulases are in high demand due to their extensive applications in various industries. Brown rot fungi, a
type of wood-rotting fungi, efficiently degrade the polysaccharide (cellulose and hemicellulose) present in the wood. In the present study, we cultivated Fomitopsis meliae (Underw.) Gilb., a
facultative brown rot fungus, both under submerged fermentation (SmF) and solid state fermentation (SSF) on wheat bran, and quantified the yield of cellulases (CMCase, FPase and β-glucosidase).
Cellulases were produced in higher quantity under SSF. Various physical parameters for SSF were optimized through One-factor-at-a-time (OFAT) approach, and their best level for higher
cellulase production by F. meliae were found as: fermentation temperature - 32‒36 °C, initial substrate pH – 4.0, substrate moisture ratio - 1:3, inoculum age - 4‒6 days old culture,
inoculum dose - 4 culture discs, substrate quantity – 5.0 g, and substrate size 0.85‒2.00 mm. The fungus consistently produced very high quantity of CMCase followed by β-glucosidase than FPase.

Abstract: Riverine floodplains, characterized by heterogeneous physico-chemical soil characteristics represent a challenging environment for plants to grow.
In these areas, lateral zonation is shaped by flooding events. Plants growing in riverine floodplains can benefit from their association with Arbuscular Mycorrhizal Fungi (AMF), as these fungi help in
alleviating the stresses associated with such environments. The present study investigated the vegetation, soil characteristics and mycorrhizal associations in three different lateral transitional zones viz.
Emergent zone (EZ), Ecotone zone (ECZ), and Core zone (CZ) within Daying Ering Wildlife Sanctuary, a riverine island of one of the big rivers in Arunachal Pradesh. Sampling was done by belt transect
method and vegetation cover, soil properties, AMF diversity, infective propagules in soil, spore density population, and host root infection were assessed in these zones. Physico-chemical properties
of soil except moisture content, varied significantly across the zones. Soil nutrients and moisture were highest in the CZ while pH and bulk density was more in the EZ. Root infection by AMF, the
number of infective propagules in soil, and the AMF spore population were highest in the CZ. The ECZ exhibited the highest values for both the Simpson and Shannon Diversity indices. The study
highlights the complex interactions between soil properties, plant community composition, and mycorrhizal associations in different lateral transitional zones of the river island.

Abstract: Fungal laccases have gained significance in diverse industrial, biotechnological and environmental applications.
Wood degrading White Rot Fungi (WRF) of the phylum Basidiomycota are an important source of laccase. Optimization of culture conditions for solid state fermentation
is reported to enhance laccase production. In the present study, optimization of the physical and biochemical factors was carried out using one factor–at–time (OFAT)
approach to maximize laccase production by Ganoderma gibbosum collected from nearby sub-tropical forest. Under unoptimized conditions, the fungus showed ~186 U/L
laccase activity. Maltose/fructose, NaNO3, and Polysorbate 60 were found to be the most effective carbon source, nitrogen source, and surfactant, respectively,
enhancing the laccase yield. With the incorporation of 10 mM ethanol and 0.5 mM CuSO4 to the growth medium, laccase yield increased approximately 4-fold and 8-fold,
respectively. These findings may be utilized for further optimization of laccase production by G. gibbosum.

Abstract: Though the relationship between nettle (Urtica dioica) and dock (Rumex obtusifolius) plants is not obligatory,
yet it may be said to be peculiar. Both grow as early colonizers near each other on soils which may not be too fertile. While nettle is known for its sting, dock lessens
the effect and relieves the pain due to the sting. They are a perfect match and dock leaves have helped many generations of people to counter the effects of nettle stings.
In the recent years, scientific investigations have reported that both Urtica dioica and Rumex obtusifolius are bestowed with healing properties against various illnesses.
The present short communication highlights the relationship between the two plants. It also draws attention to the fact that, awareness and documentation of traditional
knowledge is important. It also brings focus on the potential of these common weeds as commercial plants with many applications.
