Transcriptome profiles of the rice coleoptile of wild type and reduced adh activity (rad) mutant

Project description:Normally, rice can elongate the coleoptile under submerged condition. However, reduced adh activity (rad) mutant cannot elongate the coleoptile under submergence. To investigate the change in gene expression, we performed microarray analysis. In this analysis, we used 1 day old seedling of rice. But it is difficult to isolate only coleoptile from rice embryo without any contamination in this stage. Therefore, we applied laser microdissection (LM) technique to this microarray. By use of LM, we isolated coleoptile from rice embryo and use for microarray analysis. As the results, we found that the differences in the gene expression profiles of coleoptile between wild type and rad mutant.

Gene expression profile of rice shoot in response to macronutrient excess conditions

Project description:Macronutrients are pivotal elements for proper plant growth and development. We performed microarray analysis of rice shoot under nitrogen (N), phosphorus (P), and potassium (K) excess to obtain a global view of gene regulations associated with plant response to essential nutrients.

Gene expression analysis of rice seedling under potassium deprivation

Project description:Potassium is one of the essential macronutrients required for plant growth and development. It plays a major role in different physiological processes like cell elongation, stomatal movement, turgor regulation, osmotic adjustment, and signal transduction by acting as a major osmolyte and component of the ionic environment in the cytosol and subcellular organelles. We used whole genome microarrays to determine the transcriptomic profile of rice seedlings exposed to short-term K+ deficiency followed by K+ resupply. Potassium treated seedlings were used for RNA extraction and hybridization on Affymetrix rice Genechip by microarrays. Three biological replicates of each sample were used for microarray analysis. We wanted to know the altered expression patterns of potassium-responsive genes majorly involved in metabolic processes, stress responses, signaling pathways, transcriptional regulation, and transport of multiple molecules including K+. Seeds of indica rice were surface sterilized and grown hydroponically in rice growing medium. Plants were grown in the rice growth room under the condition of 16 h light/8 h dark (28°C) photoperiod with 70 % humidity. After 5 days of normal growth, one half of the rice seedlings were transferred to nutrient media with normal concentration of potassium (KP, 0.409 mM K2SO4) and other one half to medium without potassium (KM, 0 mM). After 5 days, potassium (0.409 mM K2SO4) was resupplied to the plants grown in KM medium for 6 h.

Comparative transcriptome analysis of banana (Musa acuminata L. AAA group, cv. Cavendish) leaves and roots in response to low-potassium stress

Project description:Potassium (K+) is a crucial macronutrient in high biomass plants, especially in banana.we comparatively studyed the phenotypic traits and transcriptomic profiles of banana leaves and roots between low potassium group (LK) and normal-potassium group (NK). In our study, the K+ content and biomass index of banana seedling were all significantly decreased under the stress of low potassium group. Moreover, thirty differentially expressed genes (DEGs) related to potassium transport and uptake and transcription factors were analyzed deeply. DEGs about ABC transporters, protein kinases and ion transporters were also detected, these genes may play important roles during potassium deficiency. These results provide valuable information about banana response to low potassium conditions.
