Wheat is a major food crop and an important component of human diet throughout the world. There are two major types of cultivated wheat; one is tetraploid durum (pasta) wheat and another one is hexaploid bread wheat. Wheat grain is the reservoir of two major dietary components – carbohydrate and protein, which get accumulated during seed maturation and directly affects yield and quality. Hexaploid, having 6 copies of each chromosome differs to a great extent from tetraploid having 4 copies of each chromosome. Studying the gene expression pattern in developing grain would help in understanding the difference in metabolic process as well as involvement of the genes in these two types of wheat. A transcriptional comparison of developing grains was carried out between the two wheat genotypes; tetraploid (AABB:PDW233) and hexaploid (AABBDD:PBW343) using RNA-seq. Approximately 194 million raw reads were obtained from both libraries. After removal of contaminations, a huge proportion (>99%), of high quality reads were obtained, were aligned to reference genome. A total of 2324 up-regulated and 522 down-regulated genes were identified as differentially expressed between PDW233 vs PBW343. Gene ontology annotation and enrichment analysis gave further information about differentially expressed genes between durum and bread wheat. This information will help in understanding process grain reserve in tetraploid and hexaploid wheat in relation to their nutritional quality.
Introduction:The human tibia is a complex anatomical unit and the knowledge of its morphometric values is important in Forensic, Anatomic and Radiological cases in order to identify unknown bodies and stature.Objective: It was to analyze the tibia, its morphometry, side difference and to investigate the position of nutrient foramina in tibia.
Methods:In this study, 60 adult human tibias (30 right and 30 left) were obtained from the Department of Anatomy SMSR SHARDA UNIVERSITY. In the study a total of two parameters i.e. Cross Section Index in the middle and Cnemicus Index of the bones were obtained and evaluated by using two instruments-a Measuring Tape and a Vernier Calipers. All the bones were dry and showed normal anatomical features.
Results:The mean Cross Section Index in the middle was calculated as 80.42 ± 11.33 on the right side and 78.15± 12.78 on the left side; and the Cnemicus index was 78.40 ± 13.19 on the right side and 70.84 ± 11.38 on the left side Conclusion: The two parameters in the North Indian population were compared with other populations. The values were found to be almost comparable however there were subtle differences between different populations. The position of nutrient foramen was also assessed. This knowledge will thus help further researchers and orthopedic surgeons in various procedures like joint replacement therapy, fracture repair, bone grafts and vascularized bone microsurgery as well as in medico-legal cases.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
