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. For flexibility in genotyping applications, SNPs polymorphic between tetraploid and diploid species were included for use in cultivated and interspecific populations...

Hundreds of LRR-RLKs play indispensable roles in a wide range of plant developmental and physiological processes. The mechanisms of keeping these LRR-RLKs at a basal and inactive status are essential but rarely studied. BKI1 is the only reported receptor kinase inhibitor in Arabidopsis, which negatively regulates BRI1 in the brassinosteroid pathway. We found BKI1 can also interact with another important LRR-RLK, ERECTA. 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...

TAL effectors delivered by phytopathogenic Xanthomonas species are DNA sequence-specific transcriptional activators of host susceptibility genes and sometimes resistance genes. The modularity of DNA recognition by TAL effectors makes them important also as tools for gene targeting and genome editing. Effector binding elements (EBEs) recognized by native TAL effectors in plants have been identified only on the forward strand of target promoters. Here, we demonstrate that TAL effectors can drive plant transcription from EBEs on either strand and in both directions...

Abscisic acid (ABA) is a major phytohormone involved in important stress-related and developmental plant processes. Membrane-delimited ABA signal transduction plays an important role in early ABA signaling, but the molecular mechanisms connecting core signaling components to the plasma membrane (PM) are unclear. Plants have evolved a large number of receptor-like kinases (RLKs) to modulate diverse biological processes by perceiving extracellular stimuli and activating downstream signaling responses. Here, a putative leucine-rich repeat (LRR)-RLK gene named RECEPTOR DEAD KINASE1 (AtRDK1) was identified and characterized in Arabidopsis thaliana...

Upon exposure to light, developing seedlings undergo photomorphogenesis, as illustrated by inhibition of hypocotyl elongation, cotyledon opening, and leaf greening. Hypocotyl growth is a well-established model for photomorphogenesis studies. During hypocotyl photomorphogenesis, light signals are sensed by multiple photoreceptors, among which the red/far-red light-sensing phytochromes have been extensively studied. However, it is not fully understood how the phytochromes modulate hypocotyl growth. Here, we demonstrated that HIGH EXPRESSION OF OSMOTICALLY RESPONSIVE GENES 1 (HOS1), which is known to either act as E3 ubiquitin ligase or affect chromatin organization, inhibits the transcriptional activation activity of PHYTOCHROME INTERACTING FACTOR 4 (PIF4) that promotes hypocotyl growth...
