napus QTL for seed weight, along with comparative mapping data, we were able to navigate to potential orthologous genome regions in A. thaliana. this helps us to identify 29 promising candidate genes with supposed physical linkage to homologous Brassica genome regions involved in seed weight. Our results suggest the following 9014 homologous genes were mapped in the CIs of 47 QTLs. A large number of important genes were found to be candidate genes for seed weight. It is interesting to notice…

The objective of this study was to investigate the impact of changing soil textures and nutrient availabilities upon biomass allocation within Brassica rapus. From the data collected, we can conclude that soil texture and it’s influence upon nutrient availability is significant in determining biomass allocation within B. rapus. In our study, we found that soil texture primarily determined root biomass while the degree of nutrient availability, provided by fertilization, primarily determined…

Summary 1: Sodium and excessiveness of it is one of the main factors increasing the risk of cardiovascular disease and stroke in Americans. The purpose of this study was to test the relationship between the amount of salt consumed and cardiovascular disease or stroke. To do this study, researchers used a systematic review and meta-analysis of studies done between 1966 through 2008. They used data sources from Medline, Embase, Psychinfo, Cochrane Library, AMED, and CINAHL. The average salt intake…

rates when introduced to different temperatures. The fishes preferred the temperature under the control group which is around 25°C. The plant Brassica rapa on the other hand has very high tolerance to pH since they have high germination rate among the variety of pH treatments. Under salinity treatments, they can only tolerate up to 10ppt of salinity. The Brassica rapa plant will have its optimum growth under pH 5 and in the control group with almost zero…

narrow host range to plants primarily in the brassicaceae. Most of the flea beetles prefer cruciferous plants which produce allyl isothiocyanate, known as aggregation pheromone of the cabbage flea beetle. The most-preferred hosts are in the genus Brassica (Cruciferae), which include the major agricultural host attacked by flea beetle, oil rapeseed and mustard. Beetles emerge…

Brassica rapa is a Wisconsin fast plant which is as well a member of the mustard family. These plants are considered fast plants because they develop very quickly, flowering in 13-18 days and completing their entire reproductive cycle in about 35 days. With these Wisconsin fast plants we observed the happening of Gregor Mendel’s principles of inheritance patterns. Starting off, some history of Gregor Mendel is that he was an Austrian monk who studied the inheritance of seven different traits in…

The central goal in evolutionary genetics is to understand how different evolutionary forces have an impact in shaping genetic variation throughout the genome (Hellmann et al., 2005). Among those evolutionary forces, demographic fluctuations, such as bottlenecks, will cause genome wide variation to deviate from the neutral or usual model (Li and Durbin, 2011). Specifically, determining the effect of selection on genetic variation has been prominent among scientists since a long time ago (Phung…

and 9, the boiled extract, and hydroxylamine had on the peroxidase enzyme extracted from Brassica rapa. Emma O’Donoghue Fundamentals of Biology I Lab Professor William Olsen October 8, 2015 Abstract The purpose of this lab was to determine the effects that a number of factors had on enzyme activity. The enzyme used during this lab was peroxidase, which was extracted from the organism Brassica rapa. The peroxidase was standardized at 0.5ml, 1.0ml, and 2.0ml to determine the…

from the oilseed brassicas. Since, the oilseed brassicas are more prone to the fungal attack and thereby, resulting in reduced productivity of the oilseed. Therefore, the present investigation focuses on the studying the features such as morphological, pathological and molecular variability of Alternaria brassicae. The characteristic features of the fungal pathogen Alternaria brassicae is deeply analyzed in this part of chapter and then breeding of fungal resistant oilseed brassicas could be…

gaps concerning the correlation between the photosynthesis and respiration rates to the amount of CO2 a plant has been grown in. The objective of our research was to determine how the rate of photosynthesis and respiration are affected by growing Brassica rapa FAST PLANTS in high and low CO2 concentrations. I hypothesized that the rate of photosynthesis and the rate of respiration will not have a significant difference in correlation to the concentration of CO2 that B. rapa was grown in because…
