Computational investigation of molecular recognition in plant hormone signal transduction
Plant hormones are small molecules derived from natural metabolites that regulate plant growth, development and responses to biotic and abiotic stresses. There are nine major classes of plant hormones that have been identified, including abscisic acid, auxin, brassinosteroid, cytokinin, ethylene, …

Characterization of the IBR5-PAD1 Interaction in Arabidopsis Auxin Response
Many plant hormones utilize the ubiquitin-proteasome system (UPS) to modulate the expression of specific genes involved in various developmental processes as well as responses to environmental stress. In this process the target proteins are polyubiquitinated by a multi-subunit E3 ubiquitin ligase …

An Analysis of the Arabidopsis Aquaporin TIP1;1 and Analysis of Stress Response Signaling in Arabidopsis
… stress responses or the response to plant hormones. The analysis, focused on the salt regulated genes, used the fuzzy k-means clustering method to identify the common and different responses between these treatments. Then, the analysis was expanded to cover all the genes in the ATH1 …

Evaluation of Methods for Control of Vegetation in Utility Corridors
… activities include mechanical trimming, planting management, or use of tree growth regulators (chemicals that suppress the production of gibberellins, the plant hormones that control stem elongation). Choosing the appropriate control method is a decision that vegetation program managers …

Unraveling Molecular Mechanisms Regulating Dormancy and Bloom Time in Apple (Malus × domestica Borkh)
… investigated the accumulation kinetics of plant hormones, carbohydrates, and reactive oxygen species (ROS) throughout the dormancy-regrowth cycle. Our results indicated that both cultivars required 1000 chilling hours for endodormancy release, but 'Honeycrisp' required 1000 growing degree …

Advancing Precision Agriculture Through AI and Statistical Modeling: Transforming Crop and Livestock Management
… focusing on both livestock man- agement and plant biology. The first part investigates automated weight prediction of beef cattle using computer vision techniques, including YOLOv9 and InternImage with Cas- cade R-CNN for precise image segmentation. Advanced feature extraction methods …

Functional genomics through metabolite profiling and gene expression analysis in Arabidopsis thaliana
… of the most important goals for the community of plant biologists is to take full advantage of the knowledge generated by the Arabidopsis thaliana genome project, and to employ state-of-the-art functional genomics techniques to assign function to each gene. This will be achieved through a complete …

Investigating the Roles of Three Aintegumenta-Like Genes In Maintenance of Arabidopsis Shoot Meristem Activity
… structure at the shoot apex of higher plants, is established during development of the embryo. After germination, the indeterminate activity of the shoot apical meristem is responsible for the initiation of all aboveground parts of the plant. The shoot apical meristem continuously …

The role of auxin transport in the control of shoot branching
Branching is a highly plastic trait, enabling plants to adapt their growth form in response to environmental stimuli. In flowering plants, shoot branching is regulated through the activity of axillary buds, which grow into branches. Several classes of plant hormones have been shown to play pivotal …

Plant-parasitic nematodes: from genomics to functional analysis of parasitism genes
… practically all ecological niches, including plants. Plant-parasitic species live on plant roots, causing substantial damage to the plant and hampering its development. As such, they cause gigantic economical losses in crop production. We used a molecular approach to analyze the …

Conversion of the batch process of manufacture of maleic acid hydrazide to a continuous process
… Likewise, some herbicides killed the entire plant, while others killed only the portion sprayed. Since 19ul, however, the discovery of synthetic growth regulating substances or plant hormones as effective weedkillers has brought about a revolutionary change in the chemical control of weeds. …

Analysis of signal output by the ethylene receptor ETR1 from Arabidopsis
<p>Ethylene is one of the most important plant hormones and regulates many processes during plant growth and development. In Arabidopsis, the ethylene receptor family consists of five members: ETR1 and ERS1 have a functional histidine kinase domain and form subfamily 1; members of subfamily 2, …

Investigating the effect of mutations in lipopolysaccharides (LPS) (O-antigen and Core region) of Salmonella Typhimurium on the colonisation of “microgreens”
… for bacterial proliferation or suppression of plant immune responses. In contrast, the SGSC230 mutant strain, which has mutations in the LPS core region, showed significantly reduced attachment after multiple washes, emphasising the importance of the LPS core in bacterial adhesion and survival …

An investigation of the role of Arabidopsis thaliana plant natriuretic peptide in planta
The sessile nature of plants demands that they respond appropriately to changes in their environment (stresses) in order to survive. Critical to survival is the maintenance of water and ion homeostasis. The mechanisms by which plants achieve this are poorly understood. Traditionally plant stress …
