This paper reports the genome sequence of domesticated tomato, a major crop plant, and draft for its closest wild relative; comparative genomics reveal very little divergence between two genomes but some important differences with potato genome, another food in genus Solanum. Tomato (Solanum lycopersicum) is plant model system fruit development. Solanum one largest angiosperm genera1 includes annual perennial plants from diverse habitats. Here we present high-quality relative,...
Higher plants adapt their growth to high temperature by a dramatic change in plant architecture. It has been shown that the transcriptional regulator phytochrome-interacting factor 4 (PIF4) and phytohormone auxin are involved regulation of temperature–induced hypocotyl elongation Arabidopsis. Here we report PIF4 regulates through direct activation biosynthetic gene YUCCA8 (YUC8). We show co-upregulates transcript abundance YUC8. PIF4–dependency temperature–mediated induction YUC8 expression...
Abstract The root stem cell niche, which in the Arabidopsis thaliana meristem is an area of four mitotically inactive quiescent cells (QCs) and surrounding active cells, critical for development growth. We report here that during jasmonate-induced inhibition primary growth, jasmonate reduces activity leads to irregular QC division columella differentiation. Consistently, expression levels AP2-domain transcription factors PLETHORA1 (PLT1) PLT2, form a developmentally instructive protein...
Plant defense responses to wounding and herbivore attack are regulated by signal transduction pathways that operate both at the site of in undamaged distal leaves. Genetic analysis tomato indicates systemin its precursor protein, prosystemin, upstream components a wound-induced, intercellular signaling pathway involves biosynthesis action jasmonic acid (JA). To examine role JA systemic signaling, reciprocal grafting experiments were used analyze wound-induced expression proteinase inhibitor...
Abstract Plants have evolved sophisticated mechanisms for integration of endogenous and exogenous signals to adapt the changing environment. Both phytohormones jasmonate (JA) ethylene (ET) regulate plant growth, development, defense. In addition synergistic regulation root hair development resistance necrotrophic fungi, JA ET act antagonistically gene expression, apical hook curvature, defense against insect attack. However, molecular mechanism such antagonism between signaling remains...
Transcriptional regulation plays a central role in plant hormone signaling. At the core of transcriptional is Mediator, an evolutionarily conserved, multisubunit complex that serves as bridge between gene-specific transcription factors and RNA polymerase machinery to regulate transcription. Here, we report action mechanisms MEDIATOR25 (MED25) subunit Arabidopsis thaliana Mediator regulating jasmonate- abscisic acid (ABA)–triggered gene We show during jasmonate signaling, MED25 physically...
Abstract Plant roots show an impressive degree of plasticity in adapting their branching patterns to ever-changing growth conditions. An important mechanism underlying this adaptation ability is the interaction between hormonal and developmental signals. Here, we analyze jasmonate with auxin regulate lateral root (LR) formation through characterization Arabidopsis thaliana mutant, jasmonate-induced defective root1 (jdl1/asa1-1). We demonstrate that, whereas exogenous promotes LR wild-type...
The hormone jasmonate (JA), which functions in plant immunity, regulates resistance to pathogen infection and insect attack through triggering genome-wide transcriptional reprogramming plants. We show that the basic helix-loop-helix transcription factor (TF) MYC2 tomato (Solanum lycopersicum) acts downstream of JA receptor orchestrate JA-mediated activation both wounding responses. Using chromatin immunoprecipitation sequencing (ChIP-seq) coupled with RNA (RNA-seq) assays, we identified 655...
The phytohormone cytokinin (CK) positively regulates the activity and function of shoot apical meristem (SAM), which is a major parameter determining seed production. rice ( Oryza sativa L.) Gn1a / OsCKX2 Grain number 1a Cytokinin oxidase 2 ) gene, encodes oxidase, has been identified as quantitative trait locus contributing to grain improvement in breeding practice. However, molecular mechanism how expression regulated planta remains elusive. Here, we report that zinc finger transcription...
Flowering time of plants must be tightly regulated to maximize reproductive success. Plants have evolved sophisticated signaling network coordinate the timing flowering in response their ever-changing environmental conditions. Besides being a key immune signal, lipid-derived plant hormone jasmonate (JA) also regulates wide range developmental processes including time. Here, we report that CORONATINE INSENSITIVE1 (COI1)-dependent pathway delays Arabidopsis thaliana by inhibiting expression...
In tomato (Solanum lycopersicum), as in other plants, the immunity hormone jasmonate (JA) triggers genome-wide transcriptional changes response to pathogen and insect attack. These are largely regulated by basic helix-loop-helix (bHLH) transcription factor MYC2. The function of MYC2 depends on its physical interaction with MED25 subunit Mediator coactivator complex. Although much has been learned about MYC2-dependent activation JA-responsive genes, relatively less studied is termination...
The brassinosteroids (BRs) represent a class of phytohormones, which regulate numerous aspects growth and development. Here, det2-9 mutant defective in BR synthesis was identified from an EMS screening for defects root length, used to investigate the role development Arabidopsis. displays short-root phenotype, is result reduced cell number meristem decreased size maturation zone. Ethylene highly increased compared with wild type, resulting hyper-accumulation ethylene consequent inhibition...
Fruit color is an important horticultural trait, which greatly affects consumer preferences. In tomato, fruit determined by the accumulation of different pigments, such as carotenoids in pericarp and flavonoids peel, along with degradation chlorophyll during ripening. Since a multigenic it takes years to introgress all color-related genes single genetic background via traditional crossbreeding, avoidance linkage drag this process difficult. Here, we proposed rapid breeding strategy generate...
Plants frequently encounter wounding and have evolved an extraordinary regenerative capacity to heal the wounds. However, wound signal that triggers responses has not been identified. Here, through characterization of a tomato mutant defective in both wound-induced defense regeneration, we demonstrate tomato, plant elicitor peptide (Pep), REGENERATION FACTOR1 (REF1), acts as systemin-independent local primarily regulates response wounding. We further identified PEPR1/2 ORTHOLOG RECEPTOR-LIKE...
Abstract Jasmonic acid (JA) is a lipid-derived signal that regulates plant defense responses to biotic stress. Here, we report the characterization of JA-deficient mutant tomato (Lycopersicon esculentum) lacks local and systemic expression defensive proteinase inhibitors (PIs) in response wounding. Map-based cloning studies demonstrated this phenotype results from loss function an acyl-CoA oxidase (ACX1A) catalyzes first step peroxisomal β-oxidation stage JA biosynthesis. Recombinant ACX1A...
The size and shape of the plant leaf is an important agronomic trait. To understand molecular mechanism governing shape, we characterized a classic rice (Oryza sativa) dwarf mutant named narrow leaf1 (nal1), which exhibits characteristic phenotype leaves. In accordance with reduced blade width, leaves nal1 contain decreased number longitudinal veins. Anatomical investigations revealed that culms also show defective vascular system, in distribution pattern bundles are altered. Map-based...
Genetic analysis of the wound response pathway in tomato indicates that systemin and its precursor protein, prosystemin, are upstream components a defensive signaling cascade involves synthesis subsequent action octadecatrienoic acid (18:3)–derived plant hormone jasmonic (JA). The suppressor prosystemin-mediated responses2 (spr2) mutation, which was isolated previously as (pro)systemin-mediated signaling, impairs wound-induced JA biosynthesis production long-distance signal for expression...
Abstract The octadecanoid signaling pathway has been shown to play an important role in plant defense against various chewing insects and some pathogenic fungi. Here, we examined the interaction of a cell-content feeding arachnid herbivore, two-spotted spider mite (Tetranychus urticae Koch), with cultivated tomato (Lycopersicon esculentum) isogenic mutant line (defenseless-1 [def-1]) that is deficient biosynthesis pathway-derived signal, jasmonic acid (JA). Spider fecundity ondef-1 plants...
As a master regulator of jasmonic acid (JA)–signaled plant immune responses, the basic helix-loop-helix (bHLH) Leu zipper transcription factor MYC2 differentially regulates different subsets JA–responsive genes through distinct mechanisms. However, how itself is regulated at protein level remains unknown. Here, we show that proteolysis plays positive role in regulating its target genes. We discovered 12-amino-acid element activation domain (TAD) required for both and transcriptional activity...
