Solanum torvum Sw. is a wild Solanaceous plant species, commonly used by the indigenous people of Tripura. Cytological study of the species was carried out to determine the somatic chromosome number and to construct the karyotype formula. The detailed karyomorphological analysis revealed 2n=24 somatic chromosomes having haploid number n=12. The size of chromosomal complement was found to range from 2.14±0.21 to 4.02±0.26 µm with a pair of chromosomes bearing secondary constrictions. Strictly median primary constriction was recorded in two pairs of chromosomes. In general, karyotype formula was found to be A2B4C18. The detailed karyotype analysis revealed that chromosomes are generally small in size and fall under the Stebbins category of “2A” indicating symmetrical nature of the karyotype. The present study could be utilised in understanding the cytogenetic nature of the species and for future crop improvement programme.

Neptunia prostrate (Lamk.) Baillon, commonly used as shoot vegetable in Tripura, North East India. Young shoots are used as vegetable in different forms of recipes of tribal and rural communities of this region. The utility of the vegetable as good source of protein and total amino acids with low level of phenolics and sugar clearly indicated its significance as useful health diet and alternative food supplement to the common people. The somatic chromosome number and karyomorphological details were also investigated in this plant. Somatic chromosome number was found to be 2n=56 with karyotype formula A2B42C12. The chromosome count and constancy of the karyotype with biochemical analysis recorded in the present study.

Chromosomal study conducted in nine species of Dioscorea from different forest belts of Tripura revealed that their somatic chromosome number ranged from 2n=40 to 2n=60. The record of 2n=40 chromosome in the sexual phenotypes of Dioscorea hamiltonii, Dioscorea glabra and Dioscorea pubera are the first time report from Tripura, North East India. Moreover the somatic chromosome counts of 2n=60 in Dioscorea pentaphylla would be attributed as a new cytotype. However at the respective ploidy level no difference in somatic chromosome count was observed between their sexes.

Houttuynia cordata Thunb. (Saururaceae), has the chromosome number of 2n = 112 with karyotype formula A2+B98+C12. The size of the chromosomal complement was found to range from 1.52 µm to 3.00 µm with one pair of chromosomes bearing secondary constrictions. The detailed karyotype analysis revealed that chromosomes fall under the Stebbins category of 1A, which indicating slightly asymmetric nature of chromosome. The chromosome tally and conformity of the karyotype in the present study corroborated as a new cytotype being adapted in this area, the north-eastern region of India.

Background: Seed borne endophytic fungi play an important role in seed germination and plant health. There are ubiquitous and have been found associated in every plant species investigated so far. They colonize plant seeds without causing any disease and are often vertically transmitted. Despite their occurrence, seed borne endophytic fungi are poorly investigated and their role for application in agriculture is still to be elucidated. Methods: In the present study endophytic fungi associated with seeds of some indigenous rice varieties of North East, India was investigated. The isolates were determined for IAA activity in-vitro and antifungal activity against rice pathogen, Magnaporthe grisea. Crude metabolites obtained from potent isolates were characterized by GCMS analysis to reveal the presence of bioactive compounds. Result: Our result indicated that commonly isolated fungal genera were Aspergillus, Fusarium, Gliocladium, Mucor, Penicillium, Bipolaris, Basidiobolus and Mycelia sterilia. Amongst them, colonization frequency (CF %) of Fusarium (8.8%) was found to be highest and was isolated from seeds of almost all the varieties. It was observed that four isolates of Fusarium showed good IAA production in the medium amended with tryptophan. The isolates also displayed antifungal activity against Magnaporthe grisea. GCMS analysis of the metabolites indicated presence of several bioactive compounds. The study suggests that seed borne endophytes can be explored as bio-inoculants for crop improvement in future research program.

Beautiful City

Guwahati derives its name from the Assamese word “Guwa” means areca nut and “Haat” means market. However, the modern Guwahati had been known as the ancient Pragjyotishpura and was the capital of Assam under the Kamrupa kingdom. A beautiful city Guwahati is situated on the south bank of the river Bramhaputra. Moreover, It is known as the largest city in the Indian state of Assam and also the largest metropolis in North East India. It has also its importance as the gateway to the North- East India. Assamese and English are the spoken languages in Guwahati.  In 1667, the Mogul forces were defeated in the battle by the Ahom forces commanded by Lachut Barphukan. Thus, in a sense Guwahati became the bone of contention among the Ahoms, Kochas and the Moguls during the medieval period.  Guwahati the administrative headquarters of Lower Assam with a viceroy or Barbhukan was made by the Ahom king.  Since 1972 it has been the capital of Assam. The present paper will discuss the changes happened in Guwahati over the period of late 1970s till the present time. It will focus on the behavior of people, transformed temples, Panbazar of the city, river bank of Bramhaputra, old Fancy Bazaar, chaotic ways, festivals and seasons including a fifth man made season etc. It will also deal how over the years a city endowed with nature’s gifts and scenic views, has been changing as “a dirty city”. Furthermore, it will also present the insurgencies that have barged into the city. The occurrence of changes will be discussed through the perspective and point of view of Srutimala Duara as presented in her book Mindprints of Guwahati.

Insight Into

North- East India is an under veiled region with an awe-inspiring landscape, different groups of ethnic people, their culture and heritage. Contemporary writers from this region aspire towards a vision outside the tapered ethnic channel, and they represent a shared history. In their writings, the cultural memory is showcased, and the intensity of feeling overflows the labour of technique and craft. Mamang Dai presents a rare glimpse into the ecology, culture, life of the tribal people and history of the land of the dawn-lit mountains, Arunachal Pradesh, through her novel The Legends of Pensam. The word ‘Pensam’ in the title means ‘in-between’,  but it may also be interpreted as ‘the hidden spaces of the heart’. This is a small world where anything can happen. Being adherents of the animistic faith, the tribes here believe in co-existence with the natural world along with the presence of spirits in their forests and rivers. This paper attempts to draw an insight into the culture and gender of the Arunachalis with special reference to The Legends of Pensam by Mamang Dai.

The Status

In India, higher education is a need of hour. The excellence of Higher Edification decides the production of skilled manpower to the nation. Indian education system significantly teaching has not been tested too economical to form youths of our country employable in line with the requirement of job market. Despite the rise in range of establishments at primary, secondary and tertiary level our young educated folks don't seem to be capable of being used and recovering job opportunities. Reason being they need not non-heritable such skills essential for demand of the duty market. The present study is aimed at analyzing the status of higher education institutions in terms of Infrastructure, various courses of the institute, quality Initiatives and skill development program offered by the Institutes, in the North-East India region, so as to see whether the Higher Educational Institutes of this region are in the process of gradually developing the skills of the students in attaining excellence. The paper also laid emphasis on the measures adopted by these institutes for quality improvement, and to find out their role in combating the adversity acclaimed in the region, since this region’s development is impeded by certain inherent difficulties However, this paper focuses attention on high quality education with special emphasis on higher education for forward linkages through value addition.
