The Arabidopsis Myb Genes MYR1 and MYR2 Essay Example | Topics and Well Written Essays - 750 words

The Arabidopsis Myb Genes MYR1 and MYR2 - Essay Example Arabidopsis is a long day plant that flowers earlier than other plants in long day conditions than in short day conditions. In LD conditions flowering is affected by an increase in expression of the flowering locus T (FT). This gene expression is controlled by CONSTANS (CO). Under low light intensity, homozygous myr1 and myr2 mutants will flower and show an increase in petiole length, apical dominance and leaf angle. Analysis on the genetics of the mutants point out that myr1 and myr 2 phenotype need GA biosynthesis. In determination of the functions of MYR1 and MYR2 roles in plant development and growth two independent T-DNA alleles for every gene. The T- DNA were evaluated and discovered that they eliminated full length expression of MYR1 and MYR2 in plants homozygous to every mutation. The homozygous myr1 and myr2 mutants happened to be identical to WT plants in relation to their leaf color, plant size and morphology. In SD conditions plants that had any of these alleles had an ea rly flowering and this generally indicates that myr1 and myr2 had suppressive effects on flowering. Additionally, flowering locust T was also needed by the Myr1 and Myr2 phenotype responsible for flowering and these mutants also demonstrated an interface with phyB-9 mutant. When Myr1 and Myr2 are over expressed, GA deficiency symptoms are shown which are then eliminated by use of gibberellic acid (GA1). When Myr1 and Myr2 were lost, there was a double boost in GA20ox2 expression and GA1 levels increased by 30%. Myr2 over expression caused a three time GA20ox2 decrease and 50% reduction in GA1 levels. Therefore, it can be concluded that Myr1 and Myr2 ability to limit flowering and elongation of organs is slightly because of their destructive consequence on the bioactive GA levels. In this case, it is possible that the increase in expression for the GA negative regulators showed the property of having a shade avoidance phenotype. The role of MYR1 and MYR2 of affecting the GA2O0x2 expr ession could be the determinant for observed phenotypes and it is in the same line with research on GA2O0x2 genes that indicate their importance in regulating growth and fertility of the Arabidopsis plant. This essay is based on a previous research done by several researchers. It will describe the result, outline the conclusion and give an insight on future work based on this research. In the result that has indicated that MYR1 and MYR2 have a role in plant growth and development, it is indicated that as light intensity became high, the phenotype became weak and double mutants of myr1 and myr2 produced fewer than WT, rosette leaves. In relation, vegetative growth and flowering time characteristic of the myr1 and myr2 mutants exhibited a similarity with phyB mutants. When MYR1 and MYR2 are paralogous and the genes are co-expressed, lengthening of the vegetative period in SD conditions showed a weakening in the phenotype responsible for early flowering. Myr1 and myr2 that were early f lowering under a LD environment was connected with more features that were not present in single mutants. They a longer petiole, lengthy hypocotyls and the leaves were more vertically oriented with a peak in apical dominance. This features show that the early flowering phenotype had been strengthened and that both myr1 and myr2 double mutants expressed the presence of MYR1 and MYR2 redundancy property which was not shown in the single mutant’s myr1 and myr2. In addition it was discovered that MYR1 and M

Operations Managment - Essay Example Through the utilization of new technological applications, the said process of recruiting shall be given the most important development it is expected to take to cater to the needs of the growing number of applicants. Computers and the benefits that it provides the society has made the present generation of humanity what it needs in terms of technological assistance. Along with this, several other supporting programs were then produced to be able to give answer to other demands of the society from computing operations. Yes, it just gets better every time. Some programs are created for individuals, while some are created especially for business companies, which are controlling the global economic stability of the society today. All these programs are considered assistance for users for them to be able to have better access to the technological innovations brought about by computing operations. According to an article entitled "Computer-Tool or Tyrant", Computers, through the history of mankind have provided the society with the necessary assistance at times even more than that as it continuously develop for better applications. This claim is especially true when the talk is all about companies who are dealing with multitasking in their daily activities. The storage of the files that are needed to be kept for record could not be done through the traditional file-shelves system. Hence, the introduction of programs and operating systems brought so much ease to this so called corporal responsibilities and duties. In this paper, a suggested process of operations management using the computer office operations shall be presented so as to assist in the process of shortening the time by which an institution approves the application of hopefuls who want to enroll in Marine Officer Programs offered by the organization. Through the said process to be suggested, it is expected that the process of application would become more efficient and the process of approval be less time consuming thus allowing the personnel of the organization to put their attention to more important things such as improving the whole program for the enrollees. The Importance of Knowing How OS Works Living in such a technologically driven world, it could not be denied that the interest of people in the developing systems of computing operations is also growing. As the computing operations and applications develop, the demands of the society from the benefits that it provides for the individuals and the large organizational companies also increases. The discussion that shall be presented herein Technology too, controls the present situation of the global economy. In fact, the internet applications have completely revolutionized the processes by which trade systems are operating in the current business industry. Certainly, it could be noticed that the production of operating systems that are ready to provide business entrepreneurs with the assistance that they need to be able to cope up with the global competition of industries, the global economy tends to grow even bigger and more stable. The discussion that would be presented in this paper then shall give a clear vision on how Linux is able to provide the said needs of companies worldwide. What is it that makes Linux one of the most reliable operating
