Project description:We studied two growth phases- proliferation, and expansion in first pair of leaves in Arabidosis using two different overexpression lines of PID gene. Ectopic expression of PID lead to small rosette and leaf phenotype.
Project description:Overexpression of OsMYB103L leads to leaf rolling in transgenic rice plants. To explore the possible molecular mechanism of OsMYB103L’s effects on rice leaf development, we examined the expression profiles of OsMYB103L overexpression transgenic rice plants and wild type leaf blades using Digital Gene Expression (DGE) profiling analysis.
Project description:We examined the transcriptome induced by GmNAC81 overexpression and leaf senescence and showed that GmNAC81 further modulates leaf senescence by regulating an extensive repertoire of functionally characterized senescence-associated genes (SAGs). GmNAC81 overexpression also uncovered the regulation of typical drought-responsive genes. Key regulators and effectors of ABA signaling were suppressed by GmNAC81 overexpression.
Project description:Transcriptome of 3 developmental stages of Colletotrichum graminicola during infection of Zea mays leaf sheaths 3 biological replicates per stage. The three stages are: pre-penetration appressoria (PA), early biotrophic phase (BP), and the switch from biotrophy to necrotrophy (NP). Each biological replicate of the first stage, the pre-penetration appressoria, was sequenced to a 2-fold greater depth due to its lower representation in the samples.
Project description:To investigate effects of intake of mulberry leaf extracts on hypercholesterolemia, we performed gene expression profiling on rat liver by microarray analysis. Microarray analysis revealed that mulberry leaf extracts up-regulated the gene expression involved in suppression of cholesterol synthesis and stimulation of innate-adaptive Immunity.
Project description:We study differences in gene expression between Populus P35S::BL (BL-oe) lines and control, affecting plant growth and differentiation, and dormancy. We used microarrays to detail the global program of gene expression underlying morphological and developmental changes droved by overexpression of BL gene. We identified an activation tagging mutant with increased leaf size and correspondingly name it BIG LEAF (BL). We positioned the tag, localized a putative candidate gene and verified transcription activation. The activated gene encodes a WD40 putative transcription regulator similar to the Arabidopsis thaliana STERILE APETALA (SAP). We recapitulated the phenotype by overexpression of the gene into the same genotype under strong constitutive promoter (P35S::BL, BL-oe). Transgenic up-regulation of the BL gene caused enhanced leaf size, early bud-break, and suppression of secondary growth. BL transcript abundance in wild type plants is in apical tissues, mostly in shoot meristem, leaf primordia and axillary meristem. Our data indicates that BL plays an important role in the process of tree growth.
