Expression data from Zea mays developmental series.

ABSTRACT: Through hierarchical clustering of transcript abundance data across a diverse set of tissues and developmental stages in maize, we have identified a number of coexpression modules which describe the transcriptional circuits of maize development. We examined transcript abundance data at 50 developmental stages/tissues of maize, from embryogenesis to senescence, using a custom Affymetrix Unigene array. The VE stage is germination and emergence Vn leaf stage refers to when the collar of the nth leaf is visible.

Here, we present a genome-wide overview of transcriptional circuits in the agriculturally significant crop species maize (Zea mays). We examined transcript abundance data at 50 developmental stages, from embryogenesis to senescence, for 34,876 gene models and classified genes into 24 robust coexpression modules. Modules were strongly associated with tissue types and related biological processes. Sixteen of the 24 modules (67%) have preferential transcript abundance within specific tissues. One-t ...[more]

Structural and Metabolic Transitions of C4 Leaf Development and Differentiation Defined by Microscopy and Quantitative Proteomics in Maize

Project description:C4 grasses, such as maize (Zea mays), have high photosynthetic efficiency through combined biochemical and structural adaptations.C4 photosynthesis is established along the developmental axis of the leafblade, leading from an undifferentiated leaf base just above the ligule into highly specialized mesophyll cells (MCs) and bundle sheath cells (BSCs) at the tip. To resolve the kinetics of maize leaf development and C4 differentiation and to obtain a systems-level understanding of maize leaf formation, the accumulation profiles of proteomes of the leaf and the isolated BSCs with their vascular bundle along the developmental gradient were determined using large-scale mass spectrometry. This was complemented by extensive qualitative and quantitative microscopy analysis of structural features (e.g., Kranz anatomy, plasmodesmata, cell wall, and organelles). More than 4300 proteins were identified and functionally annotated. Developmental protein accumulation profiles and hierarchical cluster analysis then determined the kinetics of organelle biogenesis, formation of cellular structures, metabolism, and coexpression patterns. Two main expression clusters were observed, each divided in subclusters, suggesting that a limited number of developmental regulatory networks organize concerted protein accumulation along the leaf gradient. The coexpression with BSC and MC markers provided strong candidates for further analysis of C4 specialization, in particular transporters and biogenesis factors. Based on the integrated information, we describe five developmental transitions that provide a conceptual and practical template for further analysis. An online protein expression viewer is provided through the PlantProteomeDatabase.

Genetic variation of maize responses to low temperatures in controlled conditions

Project description:Eighteen genetically-diverse maize hybrids (Zea mays, dent lines crossed to a flint inbred-line) were cultivated in a growth-chamber at optimal temperature (20°C) for three weeks. They were then submitted to three successive steps of decreasing temperature ( 16, 13 and 8.5°C). Each step lasted two days. Samples were taken on the youngest ligulated leaf (fourth or fifth leaf) at the end of the period at 20°C and at the end of each temperature step. Three replicates per genotype/ temperature combination were analyzed. Each replicate was made up of the mix of leaf samples from different plants.

Global gene expression analysis in the shoot apical meristem of maize

Project description:All above ground organs of higher plants are ultimately derived from specialized organogenic structures called shoot apical meristems (SAMs). It is comprised of pluripotent stem cells, which divide to regenerate themselves as well as to provide cells to form other organs such as leaves and stems. To study global gene expression in maize SAM and very young primordia (P0 and P1), RNA was extracted from both SAMs (SAMs per se plus P0 and P1) and above-ground portions of seedlings collected from 14-day old B73 seedlings. These RNA samples were labeled and hybridized with cDNA microarrays that have 14,400 informative spots from maize. Statistical analyses showed that approximately 6.3% and 6.5% of the tested genes were significantly (p <0.0001) up- and down-regulated, respectively. Several control genes, whose expressions were confirmed in the maize SAM in the previous studies, were also up-regulated (p <0.01). The significantly up-regulated genes involved many novel transcription factor genes and regulatory genes as well as some kinds of enzymes, suggesting these genes play important roles in meristem maintenance and the early stage of leaf development in maize. Interestingly, several retrotransposon-related genes were greatly up-regulated in the SAM. This finding raised the possibility that retrotransposons are involved in regulatory mechanisms of maize SAM. An experimental aim is to identify genes preferentially expressed in maize SAM by comparing the transcript abundant between SAMs and seedlings using cDNA microarrays that have 14,400 informative spots from maize.

Global gene expression in the maize shoot apical meristem

Project description:All above ground organs of higher plants are ultimately derived from specialized organogenic structures called shoot apical meristems (SAMs). It is comprised of pluripotent stem cells, which divide to regenerate themselves as well as to provide cells to form other organs such as leaves and stems. To study global gene expression in maize SAM and very young primordia (P0 and P1), RNA was extracted from both whole SAMs (SAMs, P0 and P1) and whole seedlings (above ground part of seedlings) collected from 14-day old B73 seedlings. These RNA samples were labeled and hybridized with cDNA microarrays that have about 30,000 maize cDNA clones. Statistical analyses showed that approximately 7% and 8% of the tested genes were significantly up-regulated and down-regulated, respectively. Several control genes, whose expressions were confirmed in the maize SAM in the previous studies, were significantly up-regulated. Many histone genes and cell cycle related genes were also significantly up-regulated. Those observations validated our microarray results. The significantly up-regulated genes involved many novel transcription factor genes and regulatory genes as well as some kind of enzymes, suggesting those genes play important roles in meristem maintenance and the early stage of leaf development in maize. Surprisingly, several retrotransposon-related genes were greatly up-regulated with the statistical significance. This finding raised the possibility that retrotransposons are involved in regulatory mechanism of maize SAM. An experimental aim is to identify genes preferentially expressed in maize SAM by comparing the transcript abundant between whole SAMs and whole seedlings using cDNA microarrays that have about 30,000 maize cDNA clones.

The RHW1-ZCN4 regulatory pathway confers natural variation of husk leaf width in maize

Project description:Maize husk leaf - the outer leafy layers covering the ear - modulates kernel yield and quality. Despite its importance, however, the genetic controls underlying husk leaf development remain elusive. Our previous genome-wide association study identified a single nucleotide polymorphism located in the gene RHW1 (Regulator of Husk leaf Width) that is significantly associated with husk leaf-width diversity in maize. Here, we further demonstrate that a polymorphic 18-bp InDel (insertion/deletion) variant in the 3' untranslated region of RHW1 alters its protein abundance and accounts for husk leaf width variation. RHW1 encodes a putative MYB-like transcriptional repressor. Disruption of RHW1 altered cell proliferation and resulted in a narrower husk leaf, whereas RHW1 overexpression yielded a wider husk leaf. RHW1 positively regulated the expression of ZCN4, a well-known TFL1-like protein involved in maize ear development. Dysfunction of ZCN4 reduced husk leaf width even in the context of RHW1 overexpression. The InDel variant in RHW1 is subject to selection and is associated with maize husk leaf adaption from tropical to temperate regions. Overall, our results identify that RHW1-ZCN4 regulates a pathway conferring husk leaf width variation at a very early stage of husk leaf development in maize.
