“…In grapes, four BBX genes expression ( VvBBX2 , VvBBX3 , VvBBX13 and VvBBX22 ) were affected by ABA and ETH, and the promoter regions of all four genes contained ABRE promoter elements [ 55 ]. Three PhBBX genes ( PhBBX8 , PhBBX15 and PhBBX20 ) contained drought-responsive cis -elements were affected by drought in Petunia hybrida [ 56 ]. Moso bamboo has the property of explosive growth, which can grow about 20 m in 1.5 months [ 57 ].…”

Background The BBX (B-box) family are zinc finger protein (ZFP) transcription factors that play an essential role in plant growth, development and response to abiotic stresses. Although BBX genes have been characterized in many model organisms, genome-wide identification of the BBX family genes have not yet been reported in Moso bamboo (Phyllostachys edulis), and the biological functions of this family remain unknown. Result In the present study, we identified 27 BBX genes in the genome of Moso bamboo, and analysis of their conserved motifs and multiple sequence alignments revealed that they all shared highly similar structures. Additionally, phylogenetic and homology analyses indicated that PeBBX genes were divided into three clusters, with whole-genome duplication (WGD) events having facilitated the expansion of this gene family. Light-responsive and stress-related cis-elements were identified by analyzing cis-elements in the promoters of all PeBBX genes. Short time-series expression miner (STEM) analysis revealed that the PeBBX genes had spatiotemporal-specific expression patterns and were likely involved in the growth and development of bamboo shoots. We further explored the downstream target genes of PeBBXs, and GO/KEGG enrichment analysis predicted multiple functions of BBX target genes, including those encoding enzymes involved in plant photosynthesis, pyruvate metabolism and glycolysis/gluconeogenesis. Conclusions In conclusion, we analyzed the PeBBX genes at multiple different levels, which will contribute to further studies of the BBX family and provide valuable information for the functional validation of this family.

“…As BBX family TFs play important roles in plant development and stress responses [3], we investigated the responses of IgBBXs to various plant hormones and abiotic stress treatments. The results showed that IgBBXs were both up-regulated and down-regulated by the treatments (Figures 5 and 6), suggesting that IgBBXs might be involved in responses to various phytohormones that elicit a stress response.…”

“…Similarly, expression of IgBBX4, its I. germanica homolog, gradually increased over the course of the first 6 h, after which it somewhat decreased, and then gradually increased to the normal level at 24 h by PEG treatment, suggesting a conserved function in drought tolerance of IgBBX4. In Petunia, three PhBBX genes responded to drought stress, eight PhBBX genes responded to salt stress, and 18 PhBBX genes responded to cold stress [3]. In apple, the expression of MdBBX10 was strongly induced by NaCl and polyethylene glycol in roots and leaves [33].…”

“…In Arabidopsis, the BBX TF family has 32 members and divided into five groups according to the number of B-box domains and the presence of a CCT domain. Groups I (AtBBX1 through AtBBX6) and II (AtBBX7 through AtBBX13) have two B-boxes and a CCT domain, whereas group III (AtBBX14 through AtBBX17) has one B-box and a CCT domain; Group IV (AtBBX18 through AtBBX25) has two B-box domains without the CCT domain and Group V (AtBBX26 through AtBBX32) has only a single B-box domain [2,3]. The BBX TF family has 30 members in the rice (Oryza sativa) genome [4], 25 members in the pear (Pyrus bretschneideri Rehd) genome [5], 28 members in the petunia (Petunia hybrid) genome [3] and 64 members in the apple (Malus domestica Borkh.)…”

“…BBXs are key factors are involved in the regulation of growth and development, including flowering, shade-avoidance response, seedling photomorphogenesis, biotic and abiotic stresses and plant hormonal pathways [1,3,7,8]. BBX TFs are best known for regulating flowering.…”

The family of B-box (BBX) transcription factors contains one or two B-BOX domains and sometimes also features a highly conserved CCT domain, which plays important roles in plant growth, development and stress response. Nevertheless, no systematic study of the BBX gene family in Iris germanica L. has been undertaken. In this study, a set of six BBX TF family genes from I. germanica was identified based on transcriptomic sequences, and clustered into three clades according to phylogenetic analysis. A transient expression analysis revealed that all six BBX proteins were localized in the nucleus. A yeast one-hybrid assay demonstrated that IgBBX3 has transactivational activity, while IgBBX1, IgBBX2, IgBBX4, and IgBBX5 have no transcriptional activation ability. The transcript abundance of IgBBXs in different tissues was divided into two major groups. The expression of IgBBX1, IgBBX2, IgBBX3 and IgBBX5 was higher in leaves, whereas IgBBX4 and IgBBX6 was higher in roots. The stress response patterns of six IgBBX were detected under phytohormone treatments and abiotic stresses. The results of this study lay the basis for further research on the functions of BBX gene family members in plant hormone and stress responses, which will promote their application in I. germanica breeding.

The salinity of soil is a relevant environmental problem around the world, with climate change raising its relevance, particularly in arid and semiarid areas. Arbuscular Mycorrhizal Fungi (AMF) positively affect plant growth and health by mitigating biotic and abiotic stresses, including salt stress. The mechanisms through which these benefits manifest are, however, still unclear. This work aimed to identify key genes involved in the response to salt stress induced by AMF using RNA-Seq analysis on durum wheat (Triticum turgidum L. subsp. durum Desf. Husn.). Five hundred sixty-three differentially expressed genes (DEGs), many of which involved in pathways related to plant stress responses, were identified. The expression of genes involved in trehalose metabolism, RNA processing, vesicle trafficking, cell wall organization, and signal transduction was significantly enhanced by the AMF symbiosis. A downregulation of genes involved in both enzymatic and non-enzymatic oxidative stress responses as well as amino acids, lipids, and carbohydrates metabolisms was also detected, suggesting a lower oxidative stress condition in the AMF inoculated plants. Interestingly, many transcription factor families, including WRKY, NAC, and MYB, already known for their key role in plant abiotic stress response, were found differentially expressed between treatments. This study provides valuable insights on AMF-induced gene expression modulation and the beneficial effects of plant-AMF interaction in durum wheat under salt stress.
