Multiomics-based insights into tomato adaptation to multifactorial stress combination

ABSTRACT: Multifactorial stress combination (MFSC) represents a major threat to crop productivity under climate change scenarios. While the physiological effects of MFSC have been studied, its impact on gene expression and primary metabolism remains poorly understood in tomato plants. In this study, we performed an integrative transcriptomic and metabolomic analysis of tomato (Solanum lycopersicum) plants exposed to combinations of up to six low-intensity abiotic stresses. RNA-seq analysis revealed a stress complexity-dependent increase in differentially expressed genes (DEGs), including 258 core transcripts and 155 transcription factors uniquely regulated under 4-, 5-, and 6-stress conditions. Heat-specific analysis identified 103 uniquely regulated transcripts, including two key transcription factors (Zinc Finger TF32 and a B3-domain family protein) suggested as central regulators of different combinations involving heat stress. Our findings define a conserved, stress-complexity-dependent molecular architecture in tomato and identify candidate markers for improving crop resilience under MFSC.

Transcriptomic analysis of tomato plants subjected to multifactorial stress combination

Project description:Climate change and industrial pollution are responsible for major losses in crop yield worldwide. Tomato plants are subjected to multiple stress conditions in combination when growing in the natural field. In this work, we analyzed the transcriptomic response of tomato plants to the combination of salinity and heat stress, when plants were or were not inoculated with the beneficial bacteria Pseudomonas Putida. The results suggest that specific transcripts are regulated only under stress combination in plants inoculated with the bacteria. These transcripts could be related with the enhanced tolerance of inoculated plants under conditions of stress combination.

Combined phenotypic and transcriptomic analysis of soybean plants subjected to multifactorial stress combination

Project description:Soybean plants were subjected to a multifactorial stress combination of up to five different stresses (water deficit, salinity, low phosphate, acidity, and cadmium), in an increasing level of complexity. All stresses were applied at the beginning of the experiment except for water deficit stress that was imposed after 21 days. Leaves and flowers were collected from 5-7 different plants under the mentioned stress conditions and after 10 days of starting water deficit conditions. Differential gene expression compared to control was studied using RNAseq method for all the possible stress combinations.

Transcriptome responses to combined biotic and abiotic stresses in Arabidopsis thaliana

Project description:Biotic and abiotic stresses limit agricultural yields, and plants are often simultaneously exposed to multiple stresses. Combinations of stresses such as heat and drought or cold and high light intensity, have profound effects on crop performance and yeilds To analyze such responses, we initially compared transcriptome changes in ten Arabidopsis thaliana ecotypes using cold, heat, high light, salt and flagellin treatments as single stress factors or their double combinations. Arabidopsis thaliana plants of ecotypes (Col, Ler, C24, Cvi, Kas1, An1, Sha, Kyo2, Eri and Kond) were subjected to the following stress treatments: Salt, Cold, Heat, High Light (HL), Salt+Heat, Salt+HL, Cold+HL, Heat+HL, as well as FLG (Flagellin, flg22 peptide), Cold+FLG, Heat+FLG

Various tomato cultivars display contrasting morphological and molecular responses to a chronic heat stress

Project description:Climate change is one of the biggest threats that human society currently needs to face. Heat waves associated with global warming negatively affect plant growth and development and will increase in intensity and frequency in the coming years. Tomato is one of the most produced and consumed fruit in the world but remarkable yield losses occur every year due to the sensitivity of many cultivars to heat stress. New insights into how tomato plants are responding to heat stress will contribute to the development of cultivars with high yields under harsh temperature conditions. In this study, the analysis of microsporogenesis and pollen germination rate of eleven tomato cultivars after exposure to a chronic heat stress revealed differences between genotypes. The transcriptome of floral buds at two developmental stages of five cultivars revealed common and specific molecular responses implemented by tomato cultivars to cope with chronic heat stress. These data provide valuable insights into the diversity of the genetic response of floral buds from different cultivars to heat stress and may contribute to the development of future climate resilient tomato varieties.

HsfA2 controls the activity of developmentally and stress-regulated heat stress protection mechanisms in tomato male reproductive tissues

Project description:Male reproductive tissues are more sensitive to heat stress compared to vegetative tissues, however the basis of this phenomenon is poorly understood. Heat stress transcription factors (Hsfs) regulate the transcriptional changes required for protection and recovery from heat stress. HsfA2 has been characterized as co-activator of HsfA1a in tomato and is considered as one of the major Hsfs accumulating in response to elevated temperatures. The role of HsfA2 in heat stress response of different tissues was examined by exploring the composition and structure of the tissue-specific regulatory networks in transgenic tomato plants with suppressed HsfA2 expression (A2AS). Transcriptome analysis revealed that HsfA2 acts in condition- and tissue-specific manner and that only a subset of heat stress induced genes require HsfA2 for higher expression. Remarkably, although HsfA2 is not essential for thermotolerance in seedlings and flowering plants, it is required for maintenance pollen viability under stress conditions. We show that the activation of Hsf networks is important for the developmentally regulated priming of heat stress response occurring at early stages of anther and pollen development. Thereby, HsfA2 is involved in pollen thermotolerance by directly regulating heat stress responsive genes but also by stimulating the synthesis of molecular chaperones under non-stress conditions.

19Jan2018_Suping_LCM_TomatoHeatPollen_protein only

Project description:Heat stress is a major challenge for crop production. During the reproduction stage, pollen development is the most sensitive process to abnormal environmental conditions. In this project, we have developed a heat treatment system for tomato where plants produce a significantly lower number of pollens and the germination rate of those pollens was also very low. The size of the flower buds and pollen developmental stages were examined under confocal microscope. Pollen cells at different developmental stages were collected from flower buds at corresponding sizes using LCM. The single cell population proteomics analysis was used to identify proteome changes in a distinct group of cells. This information was used to determine the function of proteins that are associated with heat stress on cellular processes/functions during pollen development.

Simultaneous application of heat, drought and virus to Arabidopsis thaliana plants reveals significant shifts in signaling networks [triple_wdh]

Project description:Considering global climate changes, incidences of combined drought and heat stress are likely to increase in the future and will considerably influence plant-pathogen interactions. Until now, little is known about plants exposed to simultaneously occurring abiotic and biotic stresses. To shed some light on molecular plant responses to multiple stress factors, a versatile multi-factorial test system, allowing simultaneous application of heat, drought and virus stress, was developed. Comparative analysis of single, double and triple stress responses by transcriptome and metabolome analysis revealed that gene expression under multi-factorial stress is not predictable from single stress treatments. Hierarchical cluster and principal component analysis identified heat as the major stress factor clearly separating heat-stressed from non-heat stressed plants. We identified 11 genes differentially regulated in all stress combinations as well as 23 genes specifically-regulated under triple stress. Furthermore, we showed that virus treated plants displayed enhanced expression of defense genes, which was abolished in plants additionally subjected to heat and drought stress. Triple stress also reduced expression of genes involved in the R-mediated disease response and increased the cytoplasmic protein response which was not seen under single stress conditions. These observations suggested that abiotic stress factors significantly altered TuMV-specific signaling networks which lead to a deactivation of defense responses and a higher susceptibility of plants. Collectively, our transcriptome and metabolome data provide a powerful resource to study plant responses during multi-factorial stress and allows identifying metabolic processes and functional networks involved in tripartite interactions of plants with their environment.
