Proteomic analysis of two citrus rootstocks subjected to multiple abiotic stress conditions

Project description:Drought, heat and high light irradiation are abiotic stresses that negatively affect plant development and reduce crop productivity. The confluence of these three factors is common in nature, causing extreme situations for plants that compromise their viability. Drought and heat stress increase the saturation of the photosystem’s reaction centers, increasing sensitivity to high light irradiation. In addition, these stress conditions affect PSII integrity, alter redox balance of the electron transport chain and decrease photosynthetic rate. Here, we studied the effect of drought, high light and heat stress factorial stress combination on the photosynthetic apparatus of two citrus rootstocks, Carrizo citrange (Citrus sinensis × Poncirus trifoliata) and Cleopatra mandarin (Citrus reshni). Proteomic data, together with transcriptomic, showed the main responses of citrus plant to multiple abitoic stress conditions. The enhancement of KEGG pathways such as RNA metabolic processes and the accumulation of family proteins like HSPs were key responses to face the combination of these abiotic stress factors.

Transcriptome profile of Carrizo citrange roots in response to Phytophthora parasitica infection

Project description:Phytophthora parasitica is one of the most widespread Phytophthora species, which is known to cause root rot, foot rot/gummosis and brown rot of fruits in citrus. In this study, we have analyzed the transcriptome of a commonly used citrus rootstock Carrizo citrange in response to P. parasitica infection using the RNA-seq technology. In total, we have identified 6692 differentially expressed transcripts (DETs) among P. parasitica-inoculated and mock-treated roots. Of these, 3960 genes were differentially expressed at 24 hours post inoculation and 5521 genes were differentially expressed at 48 hours post inoculation. Gene ontology analysis of DETs suggested substantial transcriptional reprogramming of diverse cellular processes particularly the biotic stress response pathways in Carrizo citrange roots. Many R genes, transcription factors, and several other genes putatively involved in plant immunity were differentially modulated in citrus roots in response to P. parasitica infection. Analysis reported here lays out a strong foundation for future studies aimed at improving resistance of citrus rootstocks to P. parasitica.

The determination mechanisms of specialized food habit (live prey fish) in mandarin fish

Project description:Mandarin fish Siniperca chuatsi (Basilewsky) (Percichthyidae), as a demersal piscivore, has very specialized feeding habits, for as soon as they start feeding the fry of this fish feed solely on fry of other fish species. In rearing conditions, mandarin fish has been found to accept live prey fish only, and refuse dead prey fish or artificial diets, very little is currently known about the molecular mechanisms of multiple genes which cover different pathways influencing the specialized food habit, such as live prey. We performed transcriptome comparisons between dead prey fish feeders and nonfeeders in mandarin fish. The determination mechanisms of specialized food habit (live prey fish) in mandarin fish could provide some instructions for research of food habit in animals, including mammals.

Gene expression analysis in sensitive and tolerant Citrus rootstocks under chlorotic conditions

Project description:Iron chlorosis is one of the major abiotic stresses affecting fruit trees and other crops in calcareous soils. The most evident symptoms are connected to a reduction in growth and yield and in the interveinal chlorosis of leaves. A custom CombiMatrix 90K microarray was used to identify candidate genes involved in the citrus response to iron deficiency stress, comparing Tarocco Scirè orange [Citrus sinensis (L.) Osbeck] grafted on two different rootstocks, Swingle citrumelo (C. paradisi × Poncirus trifoliata), high sensitive, and Carrizo citrange (C. sinensis × P. trifoliata), tolerant. RNA was extracted from roots of plants grown in two different soils, one volcanic (0% of active lime) used as control, and the other calcareous (10% of active lime).

RNA-sequencing for peel roughing disorder of Satsuma mandarin fruit.

Project description:Roughing disorder (RD) is a significant quality barrier in citrus fruit, occurring more easily on easy-peeling mandarins. As RD is not yet well understood, this study aimed to examine the changes and synergic molecular processes involved. Peel with RD was induced by severely defruiting Satsuma mandarin trees. Morphology observations, RNA-sequencing and untargeted and targeted metabolic analyses were conducted.

Cryptochrome 1 attenuates plant heat stress response by light-heat stress response signal pathways crosstalk in Arabidopsis

Project description:Plants regulate growth and development in different ambient environments through light signaling pathways and heat stress signaling pathways, both of which are very important for plant adaptation to the environment, but whether there is an interaction between the two is still unclear. In this article, we reported that the blue light receptor Cryptochrome CRY1 phosphorylation will be inhibited under high temperature stress, and CRY1 activity will decrease; at this time, CRY1 could not interact with E3 ubiquitin ligase COP1(CONSTITUTIVELY PHOTOMORPHOGENIC 1) and COP1 activity increased. Its substrate HY5(ELONGATED HYPOCOTYL 5）is continuously degraded under heat stress. Through further transcriptome analysis, we found that the substrates of HY5 have a class of HSFAs（HEAT SHOCK FACTOR）HSFA2/HSFA7As/HSFA7Bs transcription factors, which are rapidly induced under heat stress conditions and activate downstream HSPs (HEAT SHOCK PROTEIN)expression.Under normal conditions, HY5 protein inhibits HSFA2/HSFA7As/HSFA7Bs. Under heat stress, HY5 protein is degraded, which releases the expression of HSFAs, thereby enhancing plant heat tolerance. In this paper, we put forward the hypothesis that the phosphorylation of CRY1 seems to be a switch in the ambient environment , and through the regulation of phosphorylation level, the light and heat stress signal are transmitted downward, forming an light-heat signal interactive regulation pathway to regulate the growth and development of plants.
