Developmental transitions require precise temporal and spatial control of gene expression. In plants, such regulation is critical for flower formation, which involves the progressive maturation stem cell populations within shoot meristems to floral meristems, followed by rapid sequential differentiation into organs. Across plant taxa, these are orchestrated F-box transcriptional cofactor UNUSUAL FLORAL ORGANS ( UFO ). The conserved pleiotropic functions offer a useful framework investigating how evolutionary processes have shaped intricate cis- key developmental genes. By pinpointing promoter sequence in an accessible chromatin region tomato ortholog , we engineered vivo series regulatory alleles that caused both loss- gain-of-function defects. These mutant phenotypes were linked disruptions predicted transcription factor binding sites known activators repressors. Allelic combinations revealed dosage-dependent interactions between opposing alleles, influencing penetrance expressivity phenotypes. phenotypic differences support robustness development requires expression dosage. Bridging our analysis Arabidopsis found although homologous sequences dispersed promoter, they maintain similar over development. However, from disrupting differ due differing patterns . Our study underscores complex dynamic genes demonstrates short stretches recruit activating repressing machinery robustness.

Climate change poses a major challenge to agriculture, affecting crop production through shifting weather patterns and an increase in extreme conditions such as heat waves, droughts, floods, all of which are further compounded by biotic stress factors.Tomatoes, vital dietary staple significant agricultural product worldwide, particularly susceptible these changes.The need for developing climate-resilient tomato varieties is more urgent than ever ensure food security.Epigenetic modifications, DNA methylation histone play essential roles gene expression regulation.These modifications can affect plant traits responses environmental stresses, enabling tomatoes maintain productivity despite variable climates or disease pressures.Tomato, model plant, offers valuable insights into the epigenetic mechanisms underlying fruit development stress.This review provides overview key discoveries regarding response resilience related epigenetics, highlighting their potential breeding strategies enhance against both abiotic challenges, thereby promoting sustainable practices context global climate change.

Abstract Background The increase in temperatures due to the current climate change dramatically affects crop cultivation, resulting yield losses and altered fruit quality. Tomato is one of most extensively grown consumed horticultural products, although it can withstand a wide range climatic conditions, heat stress affect plant growth development specially on reproductive stage, severely influencing final yield. In present work, response mechanisms thermotolerant genotype (E42) were investigated by exploring its regulatory gene network. This was achieved through promoter analysis based identification elements (HSEs) mapping promoters, combined with co-expression network aimed at identifying interactions among heat-related genes. Results highlighted 82 genes presenting HSEs belonging 52 networks obtained GCN analysis; 61 these also interact shock factors (Hsfs). Finally, list 13 candidate including two Hsfs, nine proteins (Hsps) GDSL esterase/lipase (GELPs) retrieved focusing those E42 exhibiting interacting Hsfs showing variants, compared Heinz reference genome, HIGH and/or MODERATE impact translated protein. Among these, Gene Ontology annotation evidenced that only LeHsp100 (Solyc02g088610) belongs specifically involved stress. Conclusions As whole, combination bioinformatic analyses carried out genomic trascriptomic data available for tomato, together polymorphisms detected HS-related allowed determine subset HS tomato. study provides novel approach investigation abiotic further studies will be conducted validate role

Climate change is a global problem facing all aspects of the agricultural sector. Heat stress due to increasing atmospheric temperature one most common climate impacts on agriculture. has direct effects crop production, along with indirect through associated problems such as drought, salinity, and pathogenic stresses. Approaches reported be effective mitigate heat include nano-management. Nano-agrochemicals nanofertilizers nanopesticides are emerging approaches that have shown promise against stress, particularly biogenic nano-sources. Nanomaterials favorable for production their low toxicity eco-friendly action. This review focuses different stresses production. Nano-management crops under including application nanopesticides, discussed. The potential limitations these nano-agrochemicals reviewed. Potential nanotoxicity need more investigation at local, national, levels, well additional studies into soil, plant, microbial properties processes.

Tomato (Solanum lycopersicum L.) is an economically important crop worldwide, particularly in tropical and subtropical regions. However, production significantly increasingly affected by the impacts of climate change, including heat drought stress emerging pests diseases. This study specifically evaluated effects on root shoot morphology, photosynthesis, yield traits five tomato genotypes, to identify characteristics that differentiate tolerance from susceptibility. Heat experiments were conducted a polyhouse, one during summer under high temperatures, with non-stress trial winter conducive natural conditions. Significant reductions yield, photosynthesis observed across all genotypes stress. genotype MG785-1 maintained relatively higher (298.01 ± 25.1 g), 37.7% reduction compared conditions, while CLN4786F1 showed resilience 32.3% decrease its harvest index. Root dry weight (5.91 0.53 g MG785-1) ratio (0.19 0.01 identified as key for tolerance. Physiological traits, such photosynthetic rate (11.71 1.61 µmol CO2 m−2 s−1 MG785-1), critical maintaining growth In contrast, heat-sensitive CLN3961D exhibited significant decline physiological performance. indicators tolerance, was plant These findings underscore importance integrated providing valuable insights breeding climate-resilient varieties.

Abstract Background The production of virus-free apricots ( Prunus armeniaca L.) is essential for controlling viral diseases, exchanging breeding materials without the risk spreading new and preserving plant germplasm. Plum pox virus (PPV) most devastating disease genus Hop stunt viroid (HSVd) prevalent in apricot-growing regions. It was evaluated whether thermotherapy, etiolation, or a combination both followed by meristem culture could effectively eliminate PPV HSVd from ‘Canino’ ‘Mirlo Rojo’ apricot cultivars vitro. Results In thermotherapy treatments, shoots were exposed to 38ºC 32ºC, alternating every four hours, 30, 35, 40, 45 days. Before this, acclimated heat one day at 28ºC two days 30ºC. Etiolation experiments consisted eight weeks dark conditions. A as described previously, etiolation also performed. At end each treatment, 1.5 mm meristems cultured, developed potential independent pathogen-free lines. presence absence pathogens analysed RT-PCR. combined treatments resulted highest percentages PPV-free plants (66.7 75.0%, respectively). least 40 required obtain HSVd-free plants, although best efficiency achieved (22.7%). Conclusions this study, we have an effective vitro protocol that eliminates cultivars. This first report where species.

Abstract Complex omics approaches and high-throughput phenotyping generate large, heterogeneous datasets that make linking molecular signatures to plant traits challenging. To address this challenge, here we introduce panomiX, a user-friendly toolbox for multi-omics integration, designed enable non-experts apply advanced computational methods with ease. panomiX automates data preprocessing, variance analysis, prediction, interaction modeling through machine learning, revealing meaningful interactions synergies. We applied tomato heat-stress experiment combining image-based phenotyping, transcriptomics, Fourier-transform infrared spectroscopy data, the aim of identification condition-specific, cross-domain relationships between gene expression, metabolite levels, phenotypic traits. Our approach identified network such connections, those photosynthesis stress-responsive kinases in elevated temperatures among most significant ones. By simplifying complex analyses improving interpretability, offers platform accelerate discovery trait emergence plants select specific candidate genes based on analyses.
