“…In pea, GAs reduce the number of nodules, but increase their growth in a way independent of ethylene, a key growth regulator of nodulation [185]. In Pisum sativum and Medicago truncatula, DELLA proteins regulate nodule formation by modulating the activities of KNOX and BEL1-LIKE HOMEODOMAIN (BELL) TFs [186,187]. In roots, DELLA proteins, in conjunction with other GRAS proteins, are necessary for mycorrhizal colonization.…”

Gibberellins are amongst the main plant growth regulators. Discovered over a century ago, the interest in gibberellins research is growing due to their current and potential applications in crop production and their role in the responses to environmental stresses. In the present review, the current knowledge on gibberellins’ homeostasis and modes of action is outlined. Besides this, the complex interrelations between gibberellins and other plant growth regulators are also described, providing an intricate network of interactions that ultimately drives towards precise and specific gene expression. Thus, genes and proteins identified as being involved in gibberellin responses in model and non-model species are highlighted. Furthermore, the molecular mechanisms governing the gibberellins’ relation to stress responses are also depicted. This review aims to provide a comprehensive picture of the state-of-the-art of the current perceptions of the interactions of gibberellins with other phytohormones, and their responses to plant stresses, thus allowing for the identification of the specific mechanisms involved. This knowledge will help us to improve our understanding of gibberellins’ biology, and might help increase the biotechnological toolbox needed to refine plant resilience, particularly under a climate change scenario.

“…Different species have been found to vary considerably with respect to the number of TALE family members they harbor. In this study, we identified a total of 18 CsTALE family genes in sweet orange, which compares with the 35 in Populus trichocarpa ( Zhao et al, 2019 ), 18 in Ananas comosus ( Ali et al, 2019 ), and 14 in Medicago truncatula ( Dolgikh et al, 2020 ), which could reflect differences in genome size and ploidy level. We established that the 18 Cs TALE proteins differ notably in terms of amino acid residues and physicochemical properties.…”

Three-amino-acid-loop-extension (TALE) transcription factors comprise one of the largest gene families in plants, in which they contribute to regulation of a wide variety of biological processes, including plant growth and development, as well as governing stress responses. Although sweet orange (Citrus sinensis) is among the most commercially important fruit crops cultivated worldwide, there have been relatively few functional studies on TALE genes in this species. In this study, we investigated 18 CsTALE gene family members with respect to their phylogeny, physicochemical properties, conserved motif/domain sequences, gene structures, chromosomal location, cis-acting regulatory elements, and protein–protein interactions (PPIs). These CsTALE genes were classified into two subfamilies based on sequence homology and phylogenetic analyses, and the classification was equally strongly supported by the highly conserved gene structures and motif/domain compositions. CsTALEs were found to be unevenly distributed on the chromosomes, and duplication analysis revealed that segmental duplication and purifying selection have been major driving force in the evolution of these genes. Expression profile analysis indicated that CsTALE genes exhibit a discernible spatial expression pattern in different tissues and differing expression patterns in response to different biotic/abiotic stresses. Of the 18 CsTALE genes examined, 10 were found to be responsive to high temperature, four to low temperature, eight to salt, and four to wounding. Moreover, the expression of CsTALE3/8/12/16 was induced in response to infection with the fungal pathogen Diaporthe citri and bacterial pathogen Candidatus Liberibacter asiaticus, whereas the expression of CsTALE15/17 was strongly suppressed. The transcriptional activity of CsTALE proteins was also verified in yeast, with yeast two-hybrid assays indicating that CsTALE3/CsTALE8, CsTALE3/CsTALE11, CsTALE10/CsTALE12, CsTALE14/CsTALE8, CsTALE14/CsTALE11 can form respective heterodimers. The findings of this study could lay the foundations for elucidating the biological functions of the TALE family genes in sweet orange and contribute to the breeding of stress-tolerant plants.

“…The homeobox gene is a transcriptional regulator that encodes the homeodomain (HD), which is widely found in eukaryotes. The typical HD consists of 60 amino acids, which can form a 3-helical domain in space [1][2][3]. However, there are some exceptions, such as the TALE (Three Amino-acid Loop Extension) gene families, which encode an atypical DNA binding domain consisting of 63 amino acids, with three additional amino acid residues (P-Y-P) inserted between the first and second helices [3].…”

BEL1-like homeodomain (BLH) family proteins are homeodomain transcription factors, which are found ubiquitously in plants and play important roles in regulating meristem and flower development. Although BLH proteins have been reported in some plant species, there is very little information available for plants in the Malus genus (e.g., apple tree:Malus domestica). In the present study, we identified 19 apple MdBLH genes. Phylogenetic analysis revealed that the MdBLH genes could be divided into five groups. Analysis of gene structure showed that MdBLH gene has four exons, and the third exon was 61 bp in length. Chromosomal location analysis suggested that the MdBLH genes are not distributed uniformly on 12 chromosomes. Eleven MdBLH genes were cloned by RT-PCR, and their expression patterns were also determined. Among them, the expression levels of MdBLH4.1 and MdBLH9.1 could be induced by sodium chloride stress, while the expression levels of MdATH1.1, MdBLH8.1, MdBLH8.3, and MdBLH11.1 were down-regulated by such stress. Transcriptional levels of MdATH1.1 and MdBLH7.2 were down-regulated by mannitol stress. The result of yeast two-hybrid experiment showed that MdBEL1.1 interacted with apple ovate family proteins 6 (MdOFP6), and MdBLH3.1 interacted with the MdOFP4, MdOFP6, MdOFP13, and MdOFP16 proteins. Our results provide a strong theoretical basis and a valuable reference for analyzing of the biological functions of MdBLH proteins as transcription factors in apple growth, development, and stress and also for the construction of regulatory networks.
