Expression data from Arabidopsis thaliana Col-0 transformed with constructs misexpressing NAC052 transcription factor involving leaf morphology and anatomy

ABSTRACT: In an effort to identify genetic regulators for the cell ontogeny around the veins in Arabidopsis thaliana leaves, an activation-tagged mutant line with altered leaf morphology and altered bundle sheath anatomy was characterized. This mutant had a bundle sheath-specific promoter from the gene GLYCINE DECARBOXYLASE SUBUNIT-T from the C4 species Flaveria trinervia (GLDTFt promoter) inserted in the coding region of the transcriptional repressor NAC052. Reconstruction of the mutation event of our activation-tagged line by creating a line expressing an amino-terminally truncated sequence of NAC052 under control of the GLDTFt promoter as well as creating a line expressing the full sequence of NAC052 under control of the GLDTFT promoter, as well as creating a CRISPR/Cas mutant line of NAC052, confirmed the involvement of NAC052 in leaf development.

Transcriptome of Ustilago maydis during tumour formation in bundle sheath and mesophyll cells of Zea mays L.

Project description:The biotrophic fungus Ustilago maydis causes smut disease on maize (Zea mays L.), which is characterized by immense plant tumours. To establish disease and reprogram organ primordia to tumours, U. maydis deploys effector proteins in an organ-specific manner. However, the cellular contribution to leaf tumours remains unknown. We investigated leaf tumour formation on the tissue- and cell type-specific level. Cytology and metabolite analysis were deployed to understand the cellular basis for tumourigenesis. Laser-capture microdissection was performed to gain a cell-type specific transcriptome of U. maydis during tumour formation. In-vivo visualization of plant DNA synthesis identified bundle sheath cells as the origin of hyperplasic tumour cells, while mesophyll cells become hypertrophic tumour cells. Cell type specific transcriptome profiling of U. maydis revealed tailored expression of fungal effector genes. Moreover, U. maydis See1 was identified the first cell type specific fungal effector, being required for induction of cell cycle reactivation in bundle sheath cells. Identification of distinct cellular mechanisms in two different leave cell types, and See1 as an effector for induction of proliferation of bundle-sheath cells, are major steps in understanding U. maydis-induced tumor formation. Moreover, the cell-type specific U. maydis transcriptome data is a valuable resource to the scientific community.

C4 Photosynthesis: Gene expression in mesophyll and bundle sheath cells of bundle sheath defective2 mutant

Project description:Zea mays is a C4 plant that utilizes two distinct cell types, mesophyll (M) and bundle sheath (BS), to cooperatively fix carbon. Regulation of M and BS cell differentiation is poorly understood. Here, we explore the transcriptional networks of M and BS cells by microarray analysis. The maize mutant bundle sheath defective2 lacks the accumulation of Rubisco small and large subunits (Roth et al 1996; Brutnell et al 1999) and cannot perform the Calvin Cycle (Smith et al 1998). Therefore, this mutant provides an opportunity to study M and BS cell differentiation in a perturbed BS background, potentially revealing regulons important to cell identity. M and BS cells were independently isolated from mutant and wild-type siblings. Transcriptional profiling was then performed in a cell specific manner between mutant and wild-type.

Setaria viridis small RNAs from panicle tissues

Project description:A total of 18 libraries from Setaria viridis were constructed using the Illumina TruSeq sample preparation method. We used two biological replicate libraries from the leaf, whole panicles (inside leaf sheath), whole panicles (coming out of leaf sheath), whole panicles (completely out of leaf sheath), whole panicles (completely out of leaf sheath, after pollination), spikelet (inside leaf sheath), spikelet (coming out of leaf sheath), and spikelet (completely out of leaf sheath).

A common regulatory switch controls a suite of C4 traits in multiple cell types

Project description:The C4 photosynthetic pathway provided a major advantage to plants growing in hot, dry environments, including the ancestors of our most productive crops. Two traits were essential for the evolution of this pathway: increased vein density and the functionalization of bundle sheath cells for photosynthesis. Although GRAS transcriptional regulators, including SHORT ROOT (SHR), have been implicated in mediating leaf patterning in both C3 and C4 species1-4, little is known about what controls the specialized features of the cells that mediate C4 metabolism and physiology. We show in the model monocot, Setaria viridis, that SHR regulates components of multiple cell identities, including chloroplast biogenesis and photosynthetic gene expression in bundle sheath cells, a central feature of C4 plants. Furthermore, we found that it also contributes to the two-cell compartmentalization of the characteristic four-carbon shuttle pathway. Disruption of SHR function clearly reduced photosynthetic capacity and seed yield in mutant plants under heat stress. Together, these results show how cell identities are remodeled by SHR to host the suite of traits characteristic of C4 regulation, which are a main engineering target in non-C4 crops to improve climate resilience.

Genome-wide gene expression profiling of rice Zhonghua11 and ila1 lamina joint

Project description:The leaf lamina joint joins the rice leaf blade and sheath, contributing significantly to the leaf angle trait. A more erect leaf facilitates the penetration of sunlight, enhancing photosynthetic efficiency and occupying less space in dense planting. Genetic screening found a mutant increased leaf angle1, ila1 from rice T-DNA insertional mutants library. We used microarrays to detail the transcriptional profile changes in the mutant ila1 lamina joint.

Profiling trancriptome changes that affect vein specification in maize (Zea mays) tml (TOO MANY LATERALS) mutants

Project description:The biochemistry of C4 photosynthesis relies on a specific suite of leaf functional properties, often referred to as Kranz anatomy, where there is increased vein density and the proportion of bundle sheath cells surrounding the veins compared to C3 photosynthesizing species. From a suite of putative Kranz anatomy regulators, TML was identified. Loss of function tml mutations lead to the development of large lateral veins in positions normally occupied by smaller intermediate veins in both C3 and C4 species tested. In order to elucidate the role of TML in vein patterning, we set out to profile transcriptional changes that happen in the leaf primordia upon tml knock-out in the C4 species Zea mays.

Single nuclei sequencing reveals C4 photosynthesis is based on rewiring of ancestral cell identity networks

Project description:In multicellular systems changes to the patterning of gene expression drive modifications in cell function and trait evolution. One striking example is found in more than sixty plant lineages where compartmentation of photosynthesis between cell types allowed evolution of the efficient C4 pathway from the ancestral C3 state. The molecular events enabling this transition are unclear. We used single nuclei sequencing to generate a cell level expression atlas for C3 rice and C4 sorghum during photomorphogenesis. In both species a conserved cistrome was identified for each cell type and initiation of photosynthesis gene expression was conditioned by cell identity. Photosynthesis genes switching expression from mesophyll in rice to bundle sheath in sorghum acquire hallmarks of bundle sheath identity. The sorghum bundle sheath has also acquired gene networks associated with C3 guard cells. We conclude C4 photosynthesis is based on rewiring in cis that exapts cell identity networks of C3 plants.
