Sugarcane mosaic virus (SCMV) disease causes substantial losses of grain yield and forage biomass in susceptible maize worldwide. A major quantitative trait locus, Scmv1, has been identified to impart strong resistance to SCMV at early infection stage. Here, we demonstrate that ZmTrxh, encoding an atypical h-type thioredoxin, is the causal gene at Scmv1, and that its transcript abundance correlated strongly with maize resistance to SCMV. ZmTrxh alleles, whether they are resistant or susceptible, share the identical coding/proximal promoter regions, but vary in the upstream regulatory regions...

To control gene expression directly by hormone concentrations, both animal and plant cells have exploited comparable mechanisms to sense small molecular hormones in nucleus. Whether nuclear entry of these hormones is actively transported or passively diffused, as conventionally postulated, through nuclear pore complex remains enigmatic. Here, we identified and characterized a jasmonate transporter in Arabidopsis thaliana, AtJAT1/ AtABCG16, which exhibits an unexpected dual localization in the nuclear envelope and plasma membrane...

Conserved pathogen-associated molecular patterns (PAMPs), such as chitin, are perceived by pattern recognition receptors (PRRs) located at the host cell surface and trigger rapid activation of mitogen-activated protein kinase (MAPK) cascades, which is required for plant resistance to pathogens. However, the direct link from PAMP perception to MAPK activation in plants is elusive. Here, we found that the PRR-associated receptor-like cytoplasmic kinase Oryza sativa RLCK185 transmits immune signaling from the PAMP receptor OsCERK1 to a MAPK signaling cascade through interaction with a MAPK kinase kinase, OsMAPKKKε, which is the initial kinase of the MAPK cascade...

In response to the ratio of available carbon (C) and nitrogen (N) nutrients, plants regulate their metabolism, growth, and development, a process called the C/N-nutrient response. However, the molecular basis of C/N-nutrient signaling remains unclear. In this study, we identified three CALCINEURIN B-LIKE (CBL)-INTERACTING PROTEIN KINASES (CIPKs), CIPK7, CIPK12, and CIPK14, as key regulators of the C/N-nutrient response during the post-germination growth stage in Arabidopsis. Single knockout mutants showed hypersensitivity to high C/low N conditions, a phenotype enhanced in a triple knockout mutant, indicating that CIPK7, CIPK12, and CIPK14 have a negative role in the C/N-nutrient response, and have partly redundant function...

The cuticle is a crucial barrier on the aerial surfaces of land plants. In many plants, including Arabidopsis, the sepals and petals form distinctive nanoridges in their cuticles. Yet little is known about how the formation and maintenance of these nanostructures is coordinated with the growth and development of the underlying cells. Here we characterize the cutin synthase 2 (cus2) mutant, which causes a great reduction in cuticular ridges on the mature sepal epidermis, but only a moderate effect on petal cone cell ridges...

Stigma exsertion, a key determinant of the rice mating system, greatly contributes to the application of heterosis in rice. As few QTLs have been fine mapped or cloned, the genetic architecture of stigma exsertion is quite unclear. We performed genome-wide association study of stigma exsertion and related traits using 6.5 million SNPs characterized in 533 diverse accessions of Oryza sativa. We identified 23 loci significantly associated with stigma exsertion and related traits, three of which were co-located with three major grain size genes GS3, GW5 and GW2...

Cold stress is a major environmental factor that adversely affects plant growth and development. The C-repeat Binding Factor/DRE Binding Factor 1 (CBF/DREB1) transcriptional regulatory cascade has been shown to play important roles in plant response to cold. Here we demonstrate that two key components of BR signaling modulate freezing tolerance of plants. The loss-of-function mutant of the GSK3-like kinases involved in BR signaling, bin2-3 bil1 bil2, showed increased freezing tolerance, whereas overexpression of BIN2 resulted in hypersensitivity to freezing stress under both non-acclimated and acclimated conditions...

Although auxin and brassinosteroid (BR) synergistically control various plant responses, the underlying molecular mechanism of auxin-BR crosstalk is not well understood. We previously identified SMOS1, an auxin-regulated APETALA2-type transcription factor (TF), as the causal gene of the small organ size 1 (smos1) mutant that is characterized by a decreased final size of various organs. In this study we identified another smos mutant, smos2, which shows a phenotype indistinguishable from smos1. SMOS2 was identical to the previously reported DWARF AND LOW-TILLERING (DLT), which encodes a GRAS protein involved in BR signaling...

The translocon on the outer membrane of mitochondria (TOM) facilitates import of nuclear encoded proteins. The principal machinery seems conserved in eukaryotes, however, divergence in composition and structure of TOM components has been observed between mammals, yeast and plants. TOM9, the plant homologue of yeast Tom22, is significantly smaller due to a truncation in the cytosolic receptor domain and its precise function is not understood. Here we provide evidences that TOM9.2 from Arabidopsis thaliana is involved in the formation of the mature TOM complex, most likely by influencing the assembly of the pore-forming subunit TOM40...

Genome-wide association study (GWAS) has become a widely accepted strategy for decoding genotype-phenotype associations in many species thanks to technical advances in next-generation sequencing (NGS) applications. Maize is an ideal crop for GWAS and significant progress has been made in the last decade. This review aims to summarize current GWAS efforts in maize functional genomics, and discuss future prospects in the omics era. The general goal of a GWAS analysis is to link genotypic variantions to corresponding differences in phenotype using the most appropriate statistical model in a given population...

Peanut (Arachis hypogaea; 2n = 4x = 40) is a nutritious food and a good source of vitamins, minerals, and healthy fats. Expansion of genetic and genomic resources for genetic enhancement of cultivated peanut has gained momentum from the sequenced genomes of the diploid ancestors of cultivated peanut. To facilitate high-throughput genotyping of Arachis species, 20 genotypes were re-sequenced and genome-wide single nucleotide polymorphisms (SNPs) were selected to develop a large-scale SNP genotyping array...

Hundreds of leucine-rich repeat receptor-like kinases (LRR-RLKs) play indispensable roles in a wide range of plant developmental and physiological processes. The mechanisms controlling LRR-RLKs at a basal and inactive status are essential but rarely studied. BKI1 is the only reported inhibitor of receptor kinases in Arabidopsis, which negatively regulates BRI1 in the brassinosteroid pathway. In this study, we found that BKI1 can also interact with another important LRR-RLK, ERECTA (ER). Phenotypic analysis showed that BKI1 and ER together regulate plant architecture, including pedicel orientation, which is a newly reported phenotype in the BR- and ER-mediated developmental processes...
