The altered sterol profile in smt2 mutant Arabidopsis lines showed higher levels of campesterol at the expense of sitosterol, which led to a reduced stature and growth but which could not be rescued by exogenous BR treatment (Schaffer et al., 2001). This work indicates that appropriate ratios of all sterols within the membrane are necessary for normal growth and development of plants, and that alterations in their sterol profile may cause 32 aberrant growth and development. Another important step in plant sterol…
Title Occurrence of microRNA expressions using two macronutrient deficiencies presented to Arabidopsis Thaliana Introduction Arabidopsis Thaliana was the model chosen for this experiment. It was used for miRNA expression because its entire genome is already sequenced (Weems 362-369). It is also easy to grow in difficult conditions and has a short lifespan.…
In order to exam the effects of auxin, gibberellins and abscisic acid on plant growth we generated an experiment to track the growth, specifically height of a corn seed. To begin, obtain two small planters, each with six individual compartments. Label one planter A and the other B. On the outside of the two small planters label five of the six compartments IAA, NAA, GA, ABA, and Control. The sixth compartment will not be used.…
Table 1 and Figure 1 is represented by the average root length of Brassica rapa, a fast-growing mustard plant. The Brassica rapa in the treatment group was exposed to the sagebrush (Artemisia Tridentata) stem and leaves. However, the control group only contains the Brassica rapa. As the days passed the control group surpasses the treatment group. The biggest trend for the treatment group was day 5 whereas the control group was on day 7 (as seen in Figure 1).…
In the making of cigarettes, trees are cut down for tobacco field land. When people smoke, the cigarette smoke pollutes our atmosphere. Soil that has been contaminated with cigarette smoke harmfully affects plants. Thus, there is a clear need to investigate the impact of nicotine, a substance found in cigarettes, on plant growth. I am going to test the Arabidopsis Thaliana, a model organism, to see the effect of nicotine on its growth.…

Genetic modification in both animals and plants for the purpose of faster and voluptuous growth rate is rapidly increasing. The three articles that were located, all revolve around the aspect of genetic modification in the food we consume. Genetically modified food are food derived from organisms that have undergone changes in their DNA through the processes of genetic engineering. It takes many steps to modify the genetics of an organism and they include isolating a particular gene and duplicating it several times. Additionally, there are a vast amount of benefits and concerns of genetic modification in food.…
Functional Connection between the synthesis and degradation of messenger RNAs in eukaryotic cells plays vital physiological and functional roles to shape gene expression patterns that in turn regulate diverse biological processes such as cell division and cell cycle, developmental program and biological evolution. The interplay between these two counter-intuitive processes is believed to potentially coordinate the gene expression pattern in stress response and other environmental cues where a rapid and step-wise increase in the levels of specific sets of transcripts is required within a very narrow window of time. Under such circumstances, the peaked and sharp oscillation in the steady state levels of the mRNA(s) could be more efficiently…
Landrigan, she also states in her research that more studies need to be conducted on GMOs. However, Goldbas includes the advantages of GMOs in her research which includes benefits of GMOs in medicine and also food products. She touches on the fact that GMO bacteria helps make protein insulin which can help diabetes and can support growth hormones. Regarding food products, Goldbas talks about how plants that are genetically altered can have “greater nutritional value” and “higher protein.” She goes on to add that plants are developed to be resistant to virus damage.…
Discussion The purpose of our experiment was to compare the rate of photosynthesis and respiration of Brassica rapa in ambient carbon dioxide concentrations, but grown in variable CO2 concentrations. The results we concurred from this experiment were the same as we had hypothesized, the variable growth conditions of the B. rapa plants had no significant difference on the rates of respiration and…
Roundup is implanted in some plants to allow them to grow, and to kill harmful weeds and insects. These biotechnological advancements have made…
Arabidopsis cell wall mutants INTRODUCTION & AIMS Plant cell walls are highly dynamic structure which is made up of polysaccharide such as cellulose. In plant cell, cellulose is synthesised at the plasma membrane by the enzyme cellulose synthase (CesA) which forms rosette structure with 18 CesA proteins in total. Mutating any of these CesA proteins is thought to interfere with the normal production of cellulose in plant. As cellulose is an important component of cell wall and is essential for plant growth, the expression of cellulose mutant phenotype need to be switch on after the plant has grown for some time in order to study the effect of the mutation.…

The Evolution of Genetic Modification The conventional genetic alteration of the makeup of plants has been occurring for millennia; harvesting the seeds from the best crops and planting them years down the line; breeding and crossbreeding certain genes to make foods grow bigger and give them a sweeter taste. Through this intuitive process, humans have managed to transform the small, wild tomato into a number of different varieties: from big to small, beefsteak to grape, revolutionizing the food industry with every step taken (Journal of Biotechnology). Because of the invention of GM foods, individuals across the globe are given the opportunity to broaden their palate to that of a more diverse level, allowing for a happier and healthier lifestyle. However, with the evolution of technology also comes great controversy.…
