Nowadays, hunger people were increasing dramatically because world human population is growth rapidly and food crop production were reduced by environmental problems such as drought. Drought affects the physiological processes in rice (Oryza sativa) and leading to the decreasing of yield production. Accordingly, Rootbox system used to investigate root growth dynamics of 3 rice cultivars including KDML105, Sew Mae Jan and IR64-under drought and well-watered condition and SimRoot program will be modified to modeling simulation of root growth dynamic.
Nowaday nanoparticle has used in board applications in our life such as scientific research, medicine, industrial work and even in agriculture.Although there are many studies in effect of nanoparticle on human and animals but still few limited studies on plants. One of nanoparticles that I am interested in is gold nanoparticles so the objective of my research is to study the effect of gold nanoparticles on plant growth and development.
Cadmium contamination in agricultural soil adversely affects rice production and human health. Choosing and using soil amendments wisely have been suggested as a sustainable, cheap, and environmentally friendly approach to enhance growth and reduce Cd accumulation in rice grain. My research is focused on the potential of soil amendments namely cow manure (CM) and leonardite (Leo) combined with dicalcium phosphate (DP) to reduce Cd uptake among rice KDML105, PSL2, and RD53 varieties.
Rice is one of the major food for half of the world. Rice was found that they have heavy metal accumulation problem such as arsenic, lead, cadmium. This problem is affecting ride quality grown in contaminated areas. In my research, I use Moringa leaf extract and bacteria, Tsukamurella paurometabola A155, to decrease heavy metal accumulation in rice, that’s help rice to grow better.
Roots from trees growing near house and sidewalks are know to damage
the structures. Root barriers have been intensively used to prevent such damages. However, in some area where installation could not be achieved. Chemical application is an alternative approach to inhibit root growth. My research aims to examine the potential use of Placobutrazol. I use minirhizotron and image analysis to quantify root penetration.

RootScan is a program developed for automated image analysis of anatomical feature in the root cross-sections such as aerenchyma, xylem, and phloem. We use RootScan2 to analyze the Quantitative Trait Locus of root anatomical traits of rice (Oryza sativa) to compare growth under well-watered and drought-stressed conditions.
Rhizobacteria are bacteria colonizing on the rhizosphere. Some are beneficial to plant called plant growth promoting rhizobacteria (PGPR). My project was about localization of some PGPR in maize root by using fluorescent staining dye and fluorescent microscope. Since the colonizing areas of these bacteria have impact on the mechanism of action (MOA). The more understand about MOA, the more beneficial application of PGPR. This is interesting because in the future works they can be developed to used as biofertilizer or biopesticide instead of using chemical substance.
Root hair is the important part in nutrient absorption of the plant. Some phenotypic root hair traits affected by nutrients deficiency can be seen under microscope. My project is focused on nitrogen, phosphorus, and potassium depletion affecting root hair traits in rice, corn, and soybean which are the important crops. I also try to validate the new automated program used for measuring root hair from microscopy images.
I am the assistant for Mr.Sorathan (P’ Pleum). He is doing a reseach project about the agronomical in root traits of Khao Dok Ma Li 105 mutant rice, especially the drought tolerance condition. At first, I decided to join this research because I interested in plants that can tolerate in drought condition and drought in many areas are increasing so, I want to study in this research so as to help farmers.
After helping Mr.Sorathan to do this project for a while, it make me sure that this kind of project is matched with my working style. Doing something by myself makes me know more thing even seeing something that I never know it before, so this is an insapiration that motivate me to join this lab.
Even though, I will have to work hard for it in the future, I think that it worth if I start doing this because I have learn many things.
Ps. I think that I have been happy and also got knowledges and many ideas from adviser, staffs and my own research (It is a sound from my deep heart that motivate me.).
My research project is about to develop a test kit for measuring heavy metal contamination in the plant by using the chemical method. I use rice as a model to study and also use Cadmium (Cd) as a representative of heavy metal. To measure Cadmium in rice, I use extraction method to get Cadmium ions from rice and detect those ions by using colorimetric chelation assay or/and enzyme amplified chelation assay. I am working with Dr. Tom Stewart, he is my co-advisor for this project from the faculty of Environment and Resource Studies, Mahidol University. I personally like doing this work because of my determination to help Thai farmers to reduce their production costs that will make them have a better quality of life. Plus, this work will also lead to reducing environmental impact by remediating soil contaminated with heavy metal that causes soil pollution. I would like to give specials thanks to Dr. Patompong Johns Saengwilai for giving me a chance to join this lab.
