“…As a sessile organism, Gramineae crops have to confront complicated environments. The transcription factors have been suggested as key regulators to modulate gene expression, responding to various environmental stress [44]. Previously, studies showed that the GeBP genes family play important roles in plant growth and development, as well as response to hormone and ion, implying that the GeBP genes are involved in various hormonal pathways [7,18,26].…”

The GLABROUS1 enhancer-binding protein (GeBP) gene family encodes a typical transcription factor containing a noncanonical Leucine (Leu-)-zipper motif that plays an essential role in regulating plant growth and development, as well as responding to various stresses. However, limited information on the GeBP gene family is available in the case of the Gramineae crops. Here, 125 GeBP genes from nine Gramineae crops species were phylogenetically classified into four clades using bioinformatics analysis. Evolutionary analyses showed that whole genome duplication (WGD) and segmental duplication play important roles in the expansion of the GeBP gene family. The various gene structures and protein motifs revealed that the GeBP genes play diverse functions in plants. In addition, the expression profile analysis of the GeBP genes showed that 13 genes expressed in all tested organs and stages of development in rice, with especially high levels of expression in the leaf, palea, and lemma. Furthermore, the hormone- and metal-induced expression patterns showed that the expression levels of most genes were affected by various biotic stresses, implying that the GeBP genes had an important function in response to various biotic stresses. Furthermore, we confirmed that OsGeBP11 and OsGeBP12 were localized to the nucleus through transient expression in the rice protoplast, indicating that GeBPs function as transcription factors to regulate the expression of downstream genes. This study provides a comprehensive understanding of the origin and evolutionary history of the GeBP genes family in Gramineae, and will be helpful in a further functional characterization of the GeBP genes.

Plant height, as one of the important agronomic traits of rice, is closely related to yield. In recent years, plant height-related genes have been characterized and identified, among which the DWARF3 (D3) gene is one of the target genes of miR528, and regulates rice plant height and tillering mainly by affecting strigolactone (SL) signal transduction. However, it remains unknown whether the miR528 and D3 interaction functions in controlling plant height, and the underlying regulatory mechanism in rice. In this study, we found that the plant height, internode length, and cell length of internodes of d3 mutants and miR528-overexpressing (OE-miR528) lines were greatly shorter than WT, D3-overexpressing (OE-D3), and miR528 target mimicry (OE-MIM528) transgenic plants. Knockout of D3 gene (d3 mutants) or miR528-overexpressing (OE-miR528) triggers a substantial reduction of gibberellin (GA) content, but a significant increase of abscisic acid (ABA) accumulation than in WT. The d3 and OE-miR528 transgenic plants were much more sensitive to GA, but less sensitive to ABA than WT. Moreover, the expression level of GA biosynthesis-related key genes, including OsCPS1, OsCPS2, OsKO2 and OsKAO was remarkably higher in OE-D3 plants, while the NECD2 expression, a key gene involved in ABA biosynthesis, was significantly higher in d3 mutants than in WT and OE-D3 plants. The results indicate that the miR528-D3 module negatively regulates plant height in rice by modulating the GA and ABA homeostasis, thereby further affecting the elongation of internodes, and resulting in lower plant height, which adds a new regulatory role to the D3-mediated plant height controlling in rice.

Ramie is one of the most significant fiber crops and contributes to good quality fiber. Drought stress (DS) is one of the most devastating abiotic factors which is accountable for a substantial loss in crop growth and production and disturbing sustainable crop production. DS impairs growth, plant water relation, and nutrient uptake. Ramie has evolved a series of defense responses to cope with DS. There are numerous genes regulating the drought tolerance (DT) mechanism in ramie. The morphological and physiological mechanism of DT is well-studied; however, modified methods would be more effective. The use of novel genome editing tools like clustered regularly interspaced short palindromic repeats (CRISPR) is being used to edit the recessive genes in crops to modify their function. The transgenic approaches are used to develop several drought-tolerant varieties in ramie, and further identification of tolerant genes is needed for an effective breeding plan. Quantitative trait loci (QTLs) mapping, transcription factors (TFs) and speed breeding are highly studied techniques, and these would lead to the development of drought-resilient ramie cultivars. The use of hormones in enhancing crop growth and development under water scarcity circumstances is critical; however, using different concentrations and testing genotypes in changing environments would be helpful to sort the tolerant genotypes. Since plants use various ways to counter DS, investigating mechanisms of DT in plants will lead to improved DT in ramie. This critical review summarized the recent advancements on DT in ramie using novel molecular techniques. This information would help ramie breeders to conduct research studies and develop drought tolerant ramie cultivars.
