Scientific Study from the year 2016 in the subject Biology - Genetics / Gene Technology, Mar Augusthinose College, language: English, abstract: Jackfruit (Artocarpus heterophyllus) is commonly grown in home gardens of tropical and sub-tropical countries. The fruit contains high levels of carbohydrates, protein, starch, calcium and vitamins. Jack fruit has diverse medicinal uses, especially anti-oxidant, anti-inflammatory, anti-microbial, anti-cancer and anti-fungal activity. Jackfruit is considered to be an underutilized fruit where most of the fruits get wasted due to ignorance, lack of post harvest technology and gaps in supply chain systems. Jackfruit contains more protein, calcium, iron, vitamins and other essential nutrients as compared to the common fruits. To find out the morphological variation among jack fruits among Kerala we conducted an elaborative survey and found out the parameters such as tree characteristics, leaf characterises or fruit characteristics of selected samples. Both qualitative and quantitative data are measured using field visits and standard methods and morphological indicators; after analysis of data there is a morphological variation among the jack fruit samples identified. Advances in the genetic markers such as RFLP and PCR based methods are more reliable for identification of genetic diversity than morphological markers although each technique has advantages and limitations. The objective of this research work was to estimate the level of genetic diversity and to assess genetic relationships among six varieties of jackfruit using the ‘rbcL gene’ based on PCR technique and RFLP markers. The partial sequence of ‘rbcL’ gene of six different Artocarpus varieties was used in the analysis. The size of amplified products was approximately 700 bp. After sequencing and sequence editing, sequence information on a 651 bp region was finally obtained for analysis. The alignment of sequences revealed two haplotypes out of 651 sites. The nucleotide frequencies are 27.96% (A), 29.47% (T/U), 19.69% (C), and 22.89% (G). Being one of the underutilized fruits in India, Artocarpus heterophyllus Lam has promising leads to further scientific research and livelihood strategies. The study of rbcL gene using PCR and RFLP seems to be a promising tool in establishing genetic diversity among jackfruit varieties.

Agroforestry is recognized as a sustainable land-use management in the tropics, as it provides environmental-friendly ecosystems; it also provides people with their every day need for food and cash. Since the recognition of agroforestry as a science, curricula have been developed for agroforestry programs for undergraduate and graduate trainings in Universities. Therefore, there is an urgent need to develop and make available educational material. This textbook strives to provide up-to-date information on tropical agroforestry to serve as educational material in the tropical context. The authoritative textbook of Nair (1993) on agroforestry was published 18 years ago, and before the advent of tree domestication, an important agroforestry practice today. In addition, many other research activities, such as carbon sequestration and integrated pest management, have been included in the agroforestry agenda. This textbook is intended for agroforestry students, teachers, and practitioners.

The book traces the roots of plant biotechnology from the basic sciences to current applications in the biological and agricultural sciences, industry, and medicine. Providing intriguing opportunities to manipulate plant genetic and metabolic systems, plant biotechnology has now become an exciting area of research. The book vividly describes the processes and methods used to genetically engineer plants for agricultural, environmental and industrial purposes, while also discussing related bioethical and biosafety issues. It also highlights important factors that are often overlooked by methodologies used to develop plants’ tolerance against biotic and abiotic stresses and in the development of special foods, bio-chemicals, and pharmaceuticals. The topics discussed will be of considerable interest to both graduate and postgraduate students. Further, the book offers an ideal reference guide for teachers and researcher alike, bridging the gap between fundamental and advanced approaches.
