Arabidopsis thaliana

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…

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…

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…

The gDNA for the control, A. thaliana was supplied. PCR was then utilized in two rounds with the second using nested PCR. Next, the PCR results were analyzed, and the PCR was purified. Following this step, the PCR product was ligated into a plasmid vector and bacteria was transformed. Next the plasmid had to be isolated from the bacteria and this allowed for sequencing of the DNA (Bio Rad 2017). The ultimate goal of this study was to determine the gene sequence of both Brassica Oleracea, var…

Impact of Salt on Seed Germination Introduction Germination is a key event in a plant’s lifetime and controlled by two main factors which are water and salt stress (Yuan et al., 2016 and Vallejo et al., 2010). Salt stress affects plant growth and crop production by causing osmotic and ionic stress in plants. Alonso-Blanco et al in 2009 reported that less study was made on the traits in Arabidopsis thaliana despite the immense genetic variation present in the species and the importance of seed…

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…

The intention of this experiment was to find out which of the two hormones, Gibberellic Acid or Brassinosteroids, would have the greatest effect on growth among our test subjects, the organism Arabidopsis thaliana. The results of this experiment were not as we hypothesized. Gibberellic acid proved superior in cell elongation, which can be observed by way of plant height. This was a rejection to our original hypothesis, as well as a contradiction to the study: “Interactions between…

genotypes that in turn produce new phenotypes as a result of epigenetic events in response to environmental stimuli and these phenotypes could be stable enough to both characterize the given genotype and be transmissible . Arabidopsis thaliana is a well known plant model organism useThe d in genetics and plant molecular biology. Since daylight and temperature vary on daily time and seasonal basis all around the world including areas in which Arabidopsis thaliana grows it is used in attempts to…
