“…The AmSBP1 and AmSBP2 genes of Antirrhinum majus were the first SBP-box genes to be discovered based on their ability to interact with the promoter sequence of the floral meristem identity gene SQUAMOSA ( Klein et al, 1996 ). Additional SBP-box genes were later identified, isolated, and characterized in many plants, including Arabidopsis thaliana ( Cardon et al, 1999 ), silver birch ( Lannenpaa et al, 2004 ), Salvia miltiorrhiza ( Zhang et al, 2014 ), rice ( Xie et al, 2006 ), maize ( Chuck et al, 2010 ), tomato ( Salinas et al, 2012 ), grape ( Hou et al, 2013b ), and Gossypium hirsutum ( Zhang et al, 2015 ).…”

SQUAMOSA promoter binding protein (SBP)-box genes encode plant-specific transcription factors that are extensively involved in many physiological and biochemical processes, including growth, development, and signal transduction. However, pepper (Capsicum annuum L.) SBP-box family genes have not been well characterized. We investigated SBP-box family genes in the pepper genome and characterized these genes across both compatible and incompatible strain of Phytophthora capsici, and also under different hormone treatments. The results indicated that total 15 members were identified and distributed on seven chromosomes of pepper. Phylogenetic analysis showed that SBP-box genes of pepper can be classified into six groups. In addition, duplication analysis within pepper genome, as well as between pepper and Arabidopsis genomes demonstrated that there are four pairs of homology of SBP-box genes in the pepper genome and 10 pairs between pepper and Arabidopsis genomes. Tissue-specific expression analysis of the CaSBP genes demonstrated their diverse spatiotemporal expression patterns. The expression profiles were similarly analyzed following exposure to P. capsici inoculation and hormone treatments. It was shown that nine of the CaSBP genes (CaSBP01, 02, 03, 04, 05, 06, 11, 12, and 13) exhibited a dramatic up-regulation after compatible HX-9 strain (P. capsici) inoculation, while CaSBP09 and CaSBP15 were down-regulated. In case of PC strain (P. capsici) infection six of the CaSBP genes (CaSBP02, 05, 06, 11, 12, and 13) were arose while CaSBP14 was down regulated. Furthermore, Salicylic acid, Methyl jasmonate and their biosynthesis inhibitors treatment indicated that some of the CaSBP genes are potentially involved in these hormone regulation pathways. This genome-wide identification, as well as characterization of evolutionary relationships and expression profiles of the pepper CaSBP genes, will help to improve pepper stress tolerance in the future.

“…SPL9 interacts with JA ZIM-domain (JAZ) proteins and negatively regulates JA response, though it promotes JAZ3 accumulation in Arabidopsis (Mao et al, 2017). Similarly, VpSBP5 likely participates in regulating resistance against Erysiphe necator though SA-and MeJA-mediated signal transduction pathway in grapes (Hou et al, 2013). Overexpression of CaSBP08 in transgenic N. benthamiana enhanced susceptibility to P. capsici infection, as demonstrated by the higher average disease area and disease index percentage compared to WT plants ( Figures 6B, E).…”

“…Subsequently, Lännenpää et al (2004) identified SBP-box genes in another plant, Betula pendula (i.e., BpSPL1). Similarly, Hou et al (2013) discovered VpSBP5 in Vitis vinifera, and Zhang B. et al (2017) found two others in hexaploid wheat, i.e., TaSPL20 and TaSPL21. There are many reports of SBP-box gene involvement in the development and growth of plants.…”

“…Moreover, the ortholog AtSPL6 Arabidopsis gene is necessary for the Toll and Interleukin-1 Receptor Nucleotide Binding-Leucine Rich Repeat (TIR-NB-LRR) to function in mediating resistance against Pseudomonas syringae infection (Padmanabhan et al, 2013). Hou et al (2013) reported that through the SA-induced systemic acquired resistance pathway, VpSBP5 participates in regulating resistance against Erysiphe necator and, in grapes, through the methyl jasmonate (MeJA)induced wound signaling pathway. AtSPL9 interacts with jasmonate ZIM-domain (JAZ) proteins and negatively regulates the JA response as well as resistance to insects in Arabidopsis (Mao et al, 2017).…”

Identification of Pepper CaSBP08 Gene in Defense Response Against Phytophthora capsici Infection

et al. 2020

Little information is available on the role of Squamosa promoter binding protein (SBP)-box genes in pepper plants. This family of genes is known to have transcription characteristics specific to plants and to regulate plant growth, development, stress responses, and signal transduction. To investigate their specific effects in pepper (Capsicum annuum), we screened pepper SBP-box family genes (CaSBP genes) for Phytophthora capsici (P. capsici) resistance genes using virus-induced gene silencing. CaSBP08, CaSBP11, CaSBP12, and CaSBP13, which are associated with plant defense responses against P. capsici, were obtained from among fifteen identified CaSBP genes. The function of CaSBP08 was identified in pepper defense response against P. capsici infection in particular. CaSBP08 protein was localized to the nucleus. Silencing of CaSBP08 enhanced resistance to P. capsici infection. Following P. capsici inoculation, the malondialdehyde content, peroxidase activity, and disease index percentage of the CaSBP08-silenced plants decreased compared to the control. Additionally, the expression levels of other defense-related genes, especially those of CaBPR1 and CaSAR8.2, were more strongly induced in CaSBP08-silenced plants than in the control. However, CaSBP08 overexpression in Nicotiana benthamiana enhanced susceptibility to P. capsici infection. This work provides a foundation for the further research on the role of CaSBP genes in plant defense responses against P. capsici infection.

“…Nevertheless, previous studies have reported the relationship between SBP genes and plant disease resistance, such as programmed cell death in Arabidopsis (Stone et al, 2005 ) and these studies are in agreement that programmed cell death, frequently associated to host cell death, is a common plant defense mechanisms against E. pisi (Curto et al, 2006 ; Barilli et al, 2014 ). Thus, a member of the SPB TF family ( VpSBP5 ) has been reported to be induced by powdery mildew ( E. necator ) (Hou et al, 2013 ), suggesting that this TF is involved in the resistance to powdery mildew by inducing salicylic acid and methyl jasmonate molecular signals. The C 2 C 2 (Zn)/DOF family member have divergent physiological roles (Yanagisawa, 2002 ) including defense gene expression in response to salicylic acid and oxidative stress signals (Chen et al, 1996 ; Yanagisawa, 2002 ) and phytohormone-regulated expression (De Paolis et al, 1996 ; Yanagisawa, 2002 ).…”

Resistance to powdery mildew has been studied in a number of plant species, yet the molecular mechanisms remain largely unknown. Transcription factors (TFs) play a critical role in the plant defense response by regulating the transcriptional machinery which coordinates the expression of a large group of genes involved in plant defense. Using high-throughput quantitative real-time PCR (qPCR) technology more than 1000 Medicago truncatula TFs were screened in a pair of susceptible and resistant genotypes of M. truncatula after 4 h of Erysiphe pisi infection. Seventy nine TF genes, belonging to 33 families showed a significant transcriptional change in response to E. pisi infection. Forty eight TF genes were differentially expressed in the resistant genotypes compared to the susceptible one in response to E. pisi infection, including pathogenesis-related transcriptional factors, AP2/EREBP (APETALA2/ETHYLENE-RESPONSIVE ELEMENT BINDING FACTORS), WRKY (highly conserved WRKYGQK amino-acid sequence), MYB (Myeloblastoma), homeodomain (HD) and zinc finger C2C2 (CYS2-CYS2), C2H2, (CYS2-HIS2), LIM (Lin-11, Isl-1, Mec-3) gene families, which are involved in known defense responses. Our results suggest that these TF genes are among the E. pisi responsive genes in resistant M. truncatula that may constitute a regulatory network which controls the transcriptional changes in defense genes involved in resistance to E. pisi.
