MetabolomicsNatural polymorphism of ZmICE1 contributes to amino acid metabolism that impacts cold tolerance in maize

Cold stress negatively affects maize (Zea mays L.) growth, development and yield. Metabolic adjustments contribute to the adaptation of maize under cold stress. We show here that the transcription factor INDUCER OF CBF EXPRESSION 1 (ZmICE1) plays a prominent role in reprogramming amino a...

TranscriptomicsDifferential transcript accumulation in seedling and mature shoots identifies components contributing to corn earworm resistance
As maize seedlings germinate into the soil, they encounter an environment teeming with insects seeking rich sources of nutrition. Maize presumably has developed a number of molecular mechanisms to ensure survival at the beginning of its life cycle. Bioassays indicated maize seedlings were more to...

ProteomicsLarge-scale Proteomic and Phosphoproteomic Analysis of Maize Seedling Leaves During De-etiolation
De-etiolation consists of a series of developmental and physiological changes that a plant undergoes in response to light. During this process light, an important environmental signal, triggers the inhibition of mesocotyl elongation and the production of photosynthetically active chloroplasts, and e...

ProteomicsLarge-scale Identification and Time-course Quantification of Ubiquitylomes in De-etiolating Maize Seedling Leaf
Ubiquitylation is a widely known post-translational modification that regulates myriad biochemical and physiological events in organism. The ubiquitin system is crucial for the development and fitness of higher plants. The process of de-etiolation, during which green plants initiate photomorphogenes...

TranscriptomicsDe-regulation of maize C4 photosynthetic development in a mesophyll cell defective mutant: Bundle sheath and Mesophyll
During Zea mays (maize) C4 differentiation, mesophyll (M) and bundle sheath (BS) cells accumulate distinct sets of photosynthetic enzymes, with very low photosystem II (PSII) content in BS chloroplasts. Consequently, there is little linear electron transport in the BS and ATP is generated by cyclic ...

TranscriptomicsMaize tumors caused by Ustilago maydis require organ-specific genes in host and pathogen
Two-organism transcriptome profiling of infected seedling, adult leaf, and tassel demonstrated that both the host and pathogen exhibit organ-specific expression programs. Phenotypic screening of U. maydis mutants deleted for suites of secreted protein genes and maize growth mutants demonstrated org...

TranscriptomicsExploring the mechanism of C4 photosynthetic differentiation through a unified comparative analysis of maize and rice leaf transcriptomes
Maize and rice are the two most economically important grass crops and utilize distinct forms of photosynthesis to fix carbon: C4 and C3 respectively. Relative to C3 photosynthesis, C4 photosynthesis reduces photorespiration and affords higher water and nitrogen use efficiencies under hot arid condi...

TranscriptomicsSmall RNA sequencing in maize hybrids and inbreds
Small RNAs (sRNAs) are hypothesized to contribute to hybrid vigor because they maintain genome integrity, contribute to genetic diversity, and control gene expression. We used Illumina sequencing to assess how sRNA populations vary between two maize inbred lines (B73, Mo17) and their hybrid. We samp...

TranscriptomicsDevelopmental Dynamics of Kranz Cell Transcriptional Specificity in Maize Leaf Reveals Early Onset of C4-related Processes
The comparison of the cell-specific transcriptomes of bundle sheath (BS) and mesophyll (M) cells from successive developmental stages of maize leafs reveals that the number of genes preferentially transcribed in one cell type or the other varies considerably from the sink-source transition to mature...

TranscriptomicsMaize gene expression during infection with the Ustilago maydis mutant for cluster 19A and subdeletions for individual genes of cluster 19A
Many of the genes coding for secreted protein effectors are arranged in gene clusters in the genome of the biotrophic plant pathogen Ustilago maydis. The largest of these gene clusters, cluster 19A, encodes 24 secreted effectors. Deletion of the entire cluster results in severe attenuation of virule...
