Arabidopsis

produce becomes inviable and these plants cannot successfully reproduce (Environmental Factors That… 1998). This need for a specific temperature hold true to Arabidopsis thaliana just like any other plant with its optimal temperature at 25 C° for the wild type species (R.L. Vellanoweth 1995). In this study, Arabidopsis wild type plants will be compared…

The Importance of Phosphate Levels (NaH2PO4) on Proper Arabidopsis thaliana Development Introduction Proper plant development is dependent on nutrient availability (Krouk et al. 2011). In this regard, plants can respond to nutrient availability by changing their root system architecture. In particular, phosphate (NaH2PO4) levels were found to affect the root system architecture in Arabidopsis thaliana (Williamson et al. 2001), which might impact overall plant development. A better…

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…

The effect of NaCl treatment on growth and development of Arabidopsis thaliana Introduction Arabidopsis thaliana is a small flowering plant native to Europe and Asia. It is part of the mustard (Brassicaceae) family and is quite common and widespread, found in habitats such as rocky ground, sand dunes and disturbed habitats (e.g. weed gardens and waste ground). It has a 6 week generation time. On the first week two cotyledons emerge from the seed and more leaves develop up until the fourth to…

The Arabidopsis thaliana, world’s most widely known and used plant model organism today, yet what Characteristics caught scientists attention and why was this small flowering plant chosen. Also under what circumstance had it preserved through that allowed it to be crowned the title model organism. Arabidopsis first interested scientists as a self-pollinating plant that would completes its life cycle within 6 weeks, alongside the characteristic of the smaller genome size (1.2 × 108 bp) than…

Sulfamethazine remediation potential of Arabidopsis thaliana root ABSTRACT The use of antibiotics in animals either as a growth promoting or as a disease treating agent has become a worldwide trend. Antibiotics being stable bioactive compounds are not fully absorbed into the animal system and are released into the environment through animal manure. This study aims to discern the effect of one such veterinary antibiotic, sulfamethazine, on Arabidopsis thaliana root and also the possible…

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. This all makes it an easy plant to work with for research (Weems 362-369). The macronutrients phosphorus and sulfur were used for the study…

determine how to determine how environmental stresses affect miRNAs expression on Arabidopsis thaliana. According to the three graphs, miR156 levels expression is relatively low though it is above normal. We can explain it by the fact that miR156 controls the SPL genes and the flowering. Since the plant only grew for about two weeks, it didn’t get the opportunity to enter the flowering stage, in fact, foe the plant to enter the flowering stage, miR156 have to extend the juvenile stage of the…

Introduction- Greta Arabidopsis is a plant commonly used in genotype tests. They display qualities that make them convenient for altering their genes without a lot of trouble. Consequently, there are several different genotypes of Arabidopsis. However, it is rather hard to test exactly what the genotypes do to the plants without some sort of stress being placed on them. This is a record of the experiments produced and their results. These experiments were important due to their nature- many…

The orthologs of candidate genes in QTL regions and their annotation in Arabidopsis were obtained from the result of BLASTn based on gene sequence. Some genes related to seed weight from papers and some searched from Arabidopsis database (https://www.arabidopsis.org/index.jsp) using key words “seed weight”, “seed size”, “cell number” and “endosperm growth”. Homologues were clustered and analyzed using the Database for Annotation Visualization and Integrated Discovery (DAVID) tool, an online…
