“…[39]. These results suggest that some SPL genes were involved in response to various stresses [31,37,39]. In our study, the expression analysis of TaSPL genes under various stresses by RNA-seq data indicated that some TaSPL genes responded to drought, heat, cold, stripe rust or powdery mildew stresses (Additional le11: Figure S3 and Additional le 12: Table S9).…”

“…Previous studies have shown that SPL genes could response to drought [39], heat [64], auxin (IAA) and brassinolide signal pathways [55], biotic and abiotic tresses [37,39]. To examine the effects of different abiotic stresses and plant hormone on TaSPL gene expression, wheat cultivar Chinese Spring seedlings were treated with drought, PEG6000, NaCl, Cold, ABA, IAA, GA, GR24, MeJA and BR, and the qRT-PCR method also used to investigate the expression levels of the eight TaSPL genes (Fig.…”

“…The SPL genes also exerted considerable in uence in biotic and abiotic stresses. Overexpression of OsSPL9 induced Cu accumulation in rice grains [37]. FBR6/SPL14, as a transcriptional regulator, was considered to contribute not only to the development of plant architecture but also to FB1 sensitivity [31].…”

Background: The SQUAMOSA-PROMOTER BINDING PROTEIN-LIKE (SPL) genes encode a family of plant-specific transcription factors that contain a conservative SBP domain. SPL proteins play important roles in plant growth and development, such as plant architecture, flowering regulation, and grain yield. However, the systematic analysis of TaSPL gene family in wheat is lacking.Results: In this study, 56 TaSPL genes were identified from wheat genome and divided into eight groups (G1-G8), according to the phylogenetic analysis of TaSPL proteins among numbers of plant species. Bioinformatics method were applied to analyse the gene structure, motif, chromosome localization, segmental duplication and synteny of total TaSPL genes and the results showed that their characteristics were different among group in the exon-intron constitution, conserved and specific motif. The expansion and evolution of the TaSPL genes occurred within the wheat genome. Total 28 of 56 TaSPL genes were predicted to be putative targets for miR156, which revealed the importance of miR156-mediated regulation in wheat. Moreover, transcript level analysis of TaSPL genes in wheat tissues by qRT-PCR discovered the diversified spatiotemporal expression patterns, based on the comparison with reference RNA-seq data. Some TaSPL genes were subject to various stress treatments including drought and hormones, etc. suggesting that these part genes probably involved in responding to hormone signals during different wheat development stages. Conclusions: Our findings show that TaSPL genes may regulate the development of spike and grain, resistance to abiotic stresses, and involve in responding to hormone signals. These results could provide a fundamentally information to further study of the functions of TaSPL genes in wheat growth and development.

“…In rice, the SPL gene family has 19 members (Xie et al, 2006), including 11 that have been linked previously with plant development and reproductive traits (Table 1). Specifically, OsSPL3, OsSPL7, and OsSPL12 impact root development (Dai et al, 2018;Shao et al, 2019), OsSPL13 and OsSPL16 impact grain size Si et al, 2016), and OsSPL2, OsSPL6, OsSPL8, OsSPL9, OsSPL14, and OsSPL17 impact overall plant growth (Lee et al, 2007;Tang et al, 2016;Wang et al, 2017;Yue et al, 2017;Wang et al, 2018). Phenotypic functions of the remaining eight OsSPL genes have not been reported in the literature (Table 1).…”

We show here conserved paired unit clustering of SPL transcription factors in rice, and document that the pattern is widespread in monocots and dicots. Through comprehensive Cas9 editing of the 19‐member OsSPL family, we find subfunctionalization but not neofunctionalization between paired genes, and widespread fitness‐related defects. We report expression interactions both within and between gene groups. These findings are important to our understanding of gene functional redundancy and retention across evolutionary time.

“…CuSBP7a belong to the Group 1. AtSPL7 and OsSPL9 are considered functional genes in copper regulation pathways and Loss-of-function mutations in SPL9 resulting in enhanced plant resistance to rice stripe virus [35,48]. Both CuSBP1b and CuSBP13a were highly up-regulated after treatment with powdery mildew in SSL508-28.…”

Background: SQUAMOSA promoter binding protein (SBP)-box genes encode a group of transcription factors which extensively play essential roles in plant development and stress responses. However, the SBP-box gene family has not been well characterized in cucumber (Cucumis sativas). Results: In present study, 15 putative SBP-box genes were identified distributing on 4 chromosomes of cucumber. Evolutionary analysis showed that the green plant SBP family originated from a common ancestor. Phylogenic analysis divided CuSBPs into 6 groups similar to those of Arabidopsis and rice. Intron-exon and motif structure within each group shared common features according to evolutionary study. Expression pattern analysis of transcriptional data about flowering and resistance to powdery mildew demonstrated conserved SBP-box genes function in vegetative-to-reproductive transition and potential roles in other regulatory pathways. Moreover, codon bias analysis explained the mutation and selection pressure exerted on genes. Conclusions: This study comprehensively characterized cucumber CuSBP gene families, which would provide a foundation to explore the functions of CuSBPs for improving yield, quality and stress tolerance of cucumber in the future.
