“…Regulation of HD‐Zip I gene expression by low temperatures was demonstrated for Arabidopsis (Cabello et al ., ), tomato (Zhang et al ., ), paper mulberry (Peng et al ., ), sunflower (Cabello et al ., ), rice (Zhang et al ., ) and wheat (Harris et al ., ). The overexpression of α‐clade HD‐Zip class I TFs conferred cold/frost tolerance to transgenic Arabidopsis and barley (Cabello et al ., ; Kovalchuk et al ., ); however, the influence on the overexpression of monocot‐specific γ‐clade members on cold or frost tolerance of transgenic plants remains to be determined.…”

SummaryCharacterization of the function of stress‐related genes helps to understand the mechanisms of plant responses to environmental conditions. The findings of this work defined the role of the wheat TaHDZipI‐5 gene, encoding a stress‐responsive homeodomain–leucine zipper class I (HD‐Zip I) transcription factor, during the development of plant tolerance to frost and drought. Strong induction of TaHDZipI‐5 expression by low temperatures, and the elevated TaHDZipI‐5 levels of expression in flowers and early developing grains in the absence of stress, suggests that TaHDZipI‐5 is involved in the regulation of frost tolerance at flowering. The TaHDZipI‐5 protein behaved as an activator in a yeast transactivation assay, and the TaHDZipI‐5 activation domain was localized to its C‐terminus. The TaHDZipI‐5 protein homo‐ and hetero‐dimerizes with related TaHDZipI‐3, and differences between DNA interactions in both dimers were specified at 3D molecular levels. The constitutive overexpression of TaHDZipI‐5 in bread wheat significantly enhanced frost and drought tolerance of transgenic wheat lines with the appearance of undesired phenotypic features, which included a reduced plant size and biomass, delayed flowering and a grain yield decrease. An attempt to improve the phenotype of transgenic wheat by the application of stress‐inducible promoters with contrasting properties did not lead to the elimination of undesired phenotype, apparently due to strict spatial requirements for TaHDZipI‐5 overexpression.

“…The HD motif can specifically bind to DNA, whereas LZ serves as a dimerization motif [9]. HD-Zips have been identified and analyzed in various plant species, such as Medicago truncatula, grape (Vitis vinifera), rice (Oryza sativa), maize (Zea mays), potato (Solanum tuberosum), wheat (Triticum aestivum) and banana [10][11][12][13][14][15][16][17]. The HD-Zips are divided into four subfamilies: HD-Zip I, HD-Zip II, HD-Zip III, HD-Zip IV based on their gene structure, conserved sequences, cis-elements and biological functions [18,19].…”

Background The HD-Zip transcription factors are unique to plants and play an essential role in plant growth, development and stress responses. The HD-Zip transcription factor family consists of a highly conserved homeodomain (HD) and a leucine zipper domain (LZ) domain. Although the HD-Zip gene family has been extensively studied in many plant species, a systematic study of the Eucalyptus HD-Zip family has not been reported until today. Here, we systematically identified 40 HD-Zip genes in Eucalyptus (Eucalyptus grandis). Besides, we comprehensively analyzed the HD-Zips of Eucalyptus by studying the homology, conserved protein regions, gene structure, 3D structure of the protein, location of the genes on the chromosomes and the expression level of the genes in different tissues. Results The HD-Zip family in Eucalyptus has four subfamilies, which is consistent with other plants such as Arabidopsis and rice. Moreover, genes that are in the same group tend to have similar exon-intron structures, motifs, and protein structures. Under salt stress and temperature stress, the Eucalyptus HD-Zip transcription factors show a differential expression pattern. Conclusions Our findings reveal the response of HD-Zip transcription factors under salt and temperature stresses, laying a foundation for future analysis of Eucalyptus HD-Zip transcription factors.

“…Many members of the HD-Zip protein have been analyzed in various plant species, including Arabidopsis ( Arabidopsis thaliana ) [ 9 ], rice ( Oryza sativa ) [ 10 ], maize ( Zea mays ) [ 11 ], tobacco ( Nicotiana sylvestris ) [ 12 ], tomato ( Solanum lycopersicum ) [ 13 ], barley ( Hordeum vulgare ) [ 14 ], soybean ( Glycine max ) [ 15 ], Medicago truncatula [ 16 ], sunflower ( Heliantus annuus ) [ 17 ], moss ( Physcomitrella patens ) [ 18 ], and poplar ( Populus trichocarpa ) [ 19 ]. The structural and functional characterization of HD-Zip proteins was limited to Arabidopsis when only a few HD-Zip proteins had been identified in other species.…”

The homeodomain-leucine zipper (HD-Zip) transcription factor family is a key transcription factor family and unique to the plant kingdom. It consists of a homeodomain and a leucine zipper that serve in combination as a dimerization motif. The family can be classified into four subfamilies, and these subfamilies participate in the development of hormones and mediation of hormone action and are involved in plant responses to environmental conditions. However, limited information on this gene family is available for the important chrysanthemum ornamental species (Chrysanthemum morifolium). Here, we characterized 17 chrysanthemum HD-Zip genes based on transcriptome sequences. Phylogenetic analyses revealed that 17 CmHB genes were distributed in the HD-Zip subfamilies I and II and identified two pairs of putative orthologous proteins in Arabidopsis and chrysanthemum and four pairs of paralogous proteins in chrysanthemum. The software MEME was used to identify 7 putative motifs with E values less than 1e-3 in the chrysanthemum HD-Zip factors, and they can be clearly classified into two groups based on the composition of the motifs. A bioinformatics analysis predicted that 8 CmHB genes could be targeted by 10 miRNA families, and the expression of these 17 genes in response to phytohormone treatments and abiotic stresses was characterized. The results presented here will promote research on the various functions of the HD-Zip gene family members in plant hormones and stress responses.
