Plant interactions with arbuscular mycorrhizal fungi have long attracted interest for their potential to promote more efficient use of mineral resources in agriculture. Their use, however, remains limited by a lack understanding the processes that determine outcome symbiosis. In this study, impact host genotype on growth response inoculation was investigated panel diverse maize lines. A 30 lines evaluated and without fungi. The line Oh43 identified show superior and, along five other...
Significance Seed desiccation tolerance (DT) is one of the most fascinating processes higher plants, and has played a fundamental role in evolution land plants. DT allows plant seeds to remain viable dry state for years even centuries. What key transcription factors (TFs) are that activate mechanisms allow maintain cellular DNA integrity centuries remains largely unknown. In this paper, we report identification TFs act as major nodes transcriptional networks regulate acquisition seed DT. We...
Fruits and seeds are the major food source on earth. Both derive from gynoecium and, therefore, it is crucial to understand mechanisms that guide development of this organ angiosperm species. In Arabidopsis, composed two congenitally fused carpels, where domains: medial lateral, can be distinguished. The domain includes carpel margin meristem (CMM) key for production internal tissues involved in fertilization, such as septum, ovules, transmitting tract. Interestingly, shows a high cytokinin...
Abstract Synchronized communication between gametophytic and sporophytic tissue is crucial for successful reproduction, hormones seem to have a prominent role in it. Here, we studied the of Arabidopsis (Arabidopsis thaliana) cytochrome P450 CYP78A9 enzyme during reproductive development. First, controlled pollination experiments indicate that responds fertilization. Second, while overexpression can uncouple fruit development from fertilization, cyp78a8 cyp78a9 loss-of-function mutant has...
The gynoecium, the female reproductive part of flower, is key for plant sexual reproduction. During its development, inner tissues such as septum and transmitting tract tissue, important pollen germination guidance, are formed. In Arabidopsis, several transcription factors known to be involved in development these tissues. One them NO TRANSMITTING TRACT (NTT), essential formation. We found that NTT protein can interact with gynoecium-related factors, including MADS-box proteins like...
Purple acid phosphatases (PAPs) play an important role in plant phosphorus nutrition, both by liberating from organic sources the soil and modulating distribution within throughout growth development. Furthermore, members of PAP protein family have been implicated a broader mineral homeostasis, stress responses We identified 33 candidate encoding gene models maize (Zea mays ssp. var. B73) reference genome. The Pap includes clear single-copy ortholog Arabidopsis AtPAP26, shown previously to...
Significance The regulatory roles of cytokinin (CK) signaling on metabolic plasticity plant response to salt stress remain widely unknown. A comprehensive metabolome and transcriptome analysis CK-signaling–defective Arabidopsis thaliana histidine-containing phosphotransfer protein ahp2,3,5 type-B regulator arr1,10,12 triple mutants under nonsaline saline conditions revealed that CK induces a reprogramming gene-to-metabolite networks involved in salinity. modulates prestress poststress...

Although cell wall remodeling is an essential feature of plant growth and development, the underlying molecular mechanisms are poorly understood. This work describes characterization Arabidopsis (Arabidopsis thaliana) plants with altered expression ARAF1, a bifunctional alpha-L-arabinofuranosidase/beta-D-xylosidase (At3g10740) belonging to family 51 glycosyl-hydrolases. ARAF1 was localized in several types vascular system roots stems, including xylem vessels parenchyma cells surrounding...
Uncovering the complex transcriptional regulatory networks (TRNs) that underlie plant and animal development remains a challenge. However, vast amount of data from public microarray experiments is available, which can be subject to inference algorithms in order recover reliable TRN architectures. In this study we present simple bioinformatics methodology uses public, carefully curated mutual information algorithm ARACNe obtain database interactions. We used Arabidopsis thaliana root samples...
Quantitative real-time RT-PCR (qRT-PCR) has become one of the most widely used methods for accurate quantification gene expression. Since there are no universal reference genes normalization, optimal strategy to normalize raw qRT-PCR data is perform an initial comparison a set independent assess stable ones in each biological model. Normalization experiment helps ensure that results both statistically significant and biologically meaningful. Tomato model choice study fleshy fruit...
Whole-genome duplication is an evolutionary force that drives speciation in all living kingdoms and notably prevalent plants. The history of plants involved at least two genomic duplications significantly expanded the plant morphology physiology spectrum. Many important crops are polyploids, showing valuable features relative to morphological stress response traits. After genome duplication, diploidization processes facilitate adjustments restore disomic inheritance. However, little known...
NO TRANSMITTING TRACT / WIP2 (NTT/WIP2) is a zinc finger transcription factor that alters developmental programs in Arabidopsis when overexpressed. Loss of NTT function, alone or combination with closely related genes, leads to defects gynoecia and roots, respectively. Its overexpression phenotype resembles the effects cytokinin treatments, suggesting potential connection this hormonal pathway. To further investigate connection, we conducted content response evaluations, transcriptome...
Here we describe an uncharacterized gene that negatively influences Arabidopsis growth and reproductive development. DRINK ME (DKM; bZIP30) is a member of the bZIP transcription factor family, expressed in meristematic tissues such as inflorescence meristem (IM), floral (FM), carpel margin (CMM). Altered DKM expression affects organ development, including gynoecium, which female structure determinant for fertility sexual reproduction. A microarray analysis indicates overexpression cell...
Abstract Background Nitrogen (N) and phosphorus (P) are macronutrients essential for crop growth productivity. In cultivated fields, N P levels rarely sufficient, contributing to the gap between realized potential production. Fertilizer application increases nutrient availability, but is not available all farmers, nor current rates of sustainable or environmentally desirable. Transcriptomic studies cereal crops have revealed dramatic responses either low single stress treatments. field,...
The Arabidopsis thaliana gynoecium arises at the center of flower as a simple structure, which will successively develop novel cell types and tissues, resulting in complex organ. Genetic hormonal factors involved this process have been identified, but we are still far from understanding how these elements interact, interactions rearrange according to spatial temporal cues. In work propose first steps roadmap attain an ambitious goal: obtain comprehensive dynamic gene regulatory network that...
