Special Issue Information

Dear Colleagues,

Phytohormones are involved in the regulation of all stages of plant ontogenesis, from seed germination to senescence and death. Primarily due to the methods of molecular genetics, outstanding results have been obtained over the past three decades in the study of the mechanisms of the perception and implementation of hormonal signals. The pathways of biosynthesis and catabolism of "basic" phytohormones and their intracellular localization have been studied, phytohormone receptors and many components of hormonal signaling have been discovered, and our knowledge of the hormonal regulation of gene expression has significantly extended. It becomes obvious that at least several phytohormones are involved in the plant response to any exogenous or endogenous factor, which makes it necessary to study in depth the ways of phytohormone interaction in the regulation of physiological processes. In addition to the nuclear genome, chloroplast and mitochondrial genomes often participate in the implementation of hormonal signals. Therefore, it is extremely important to take into account the interaction between the nucleus and cell organelles to understand the mechanism of action of phytohormones. To date, the hormonal regulation of chloroplast biogenesis has been poorly studied, and the involvement of hormones in the regulation of mitochondrial biogenesis is also far from being understood. No information is available on the mechanisms of hormonal signal transduction to chloroplasts and mitochondria. Additional challenges arise with the emergence of new very important endogenous regulators of plant growth and development, such as melatonin and the mechanisms of their crosstalk with classical phytohormones. Due to climate change, the task of increasing plant resistance to adverse environmental factors, including the use of phytohormones, is becoming increasingly in demand. Therefore, the problem of studying the role of phytohormones in plant life remains highly relevant. We encourage submissions to this Special Issue to discuss a wide range of issues concerning the hormonal regulation of physiological processes, as well as applications of phytohormones in biotechnology and agriculture, through original experimental papers, opinions, and reviews.

Kiwifruit bacterial cankers caused by Pseudomonas syringae pv. actinidiae (Psa) are a serious threat to the kiwifruit industry. Salicylic acid (SA) regulates plant defense responses and was previously found to enhance kiwifruit’s resistance to Psa. However, the underlying mechanisms of this process remain unclear. In this study, we used 4D proteomics to investigate how SA enhances kiwifruit’s resistance to Psa and found that both SA treatment and Psa infection induced dramatic changes in the proteomic pattern of kiwifruit. Psa infection triggered the activation of numerous resistance events, including the MAPK cascade, phenylpropanoid biosynthesis, and hormone signaling transduction. In most cases, the differential expression of a number of genes involved in the SA signaling pathway played a significant role in kiwifruit’s responses to Psa. Moreover, SA treatment upregulated numerous resistance-related proteins, which functioned in defense responses to Psa, including phenylpropanoid biosynthesis, the MAPK cascade, and the upregulation of pathogenesis-related proteins. We also found that SA treatment could facilitate timely defense responses to Psa infection and enhance the activation of defense responses that were downregulated in kiwifruit during infection with Psa. Thus, our research deciphered the potential mechanisms of SA in promoting Psa resistance in kiwifruit and can provide a basis for the use of SA to enhance kiwifruit resistance and effectively control the occurrence of kiwifruit bacterial cankers.

The coordination of activities between nuclei and organelles in plant cells involves information exchange, in which phytohormones may play essential roles. Therefore, the dissection of the mechanisms of hormone-related integration between phytohormones and mitochondria is an important and challenging task. Here, we found that inputs from multiple hormones may cause changes in the transcript accumulation of mitochondrial-encoded genes and nuclear genes encoding mitochondrial (mt) proteins. In particular, treatments with exogenous hormones induced changes in the GUS expression in the reporter line possessing a 5′-deletion fragment of the RPOTmp promoter. These changes corresponded in part to the up- or downregulation of RPOTmp in wild-type plants, which affects the transcription of mt-encoded genes, implying that the promoter fragment of the RPOTmp gene is functionally involved in the responses to IAA (indole-3-acetic acid), ACC (1-aminocyclopropane-1-carboxylic acid), and ABA (abscisic acid). Hormone-dependent modulations in the expression of mt-encoded genes can also be mediated through mitochondrial transcription termination factors 15, 17, and 18 of the mTERF family and genes for tetratricopeptide repeat proteins that are coexpressed with mTERF genes, in addition to SWIB5 encoding a mitochondrial SWI/SNF (nucleosome remodeling) complex B protein. These genes specifically respond to hormone treatment, displaying both negative and positive regulation in a context-dependent manner. According to bioinformatic resources, their promoter region possesses putative cis-acting elements involved in responses to phytohormones. Alternatively, the hormone-related transcriptional activity of these genes may be modulated indirectly, which is especially relevant for brassinosteroids (BS). In general, the results of this study indicate that hormones are essential mediators that are able to cause alterations in the transcript accumulation of mt-related nuclear genes, which, in turn, trigger the expression of mt genes.
