“…6G ) indicate the involvement of WOX3 genes in carpel development. Interestingly, similar ovule exposure was also reported in the loss of function of WOX1 genes in tobacco ( LAMINA1 ), M. truncatula ( STENOFOLIA ) and, more recently, tomato ( SlWOX1 ; McHale 1992 ; Tadege et al 2011 ; Zhang et al 2020 ), while it was not observed in prs mutant. In this sense, HvWOX3 and LSY1 play more closer role in the development of carpel to WOX1 than to PRS .…”

Barley (Hordeum vulgare L.) is the fourth most highly produced cereal in the world after wheat, rice, and maize and is mainly utilized as malts and for animal feed. Barley, a model crop of the tribe Triticeae, is important in comparative analyses of Poaceae. However, molecular understanding about the developmental processes is limited in barley. Our previous work characterized one of two WUSCHEL-RELATED HOMEOBOX 3 (WOX3) genes present in the barley genome: NARROW LEAFED DWARF1 (NLD1). We demonstrated that NLD1 plays a pivotal role in the development of lateral organs. In the present study, we describe a bifurcated palea (bip) mutant of barley focusing on flower and leaf phenotypes. The palea in the bip mutant was split into two and develop toward inside the lemma surrounding the carpels and anthers. The bip mutant is devoid of lodicules, which develop in a pair at the base of the stamen within the lemma in normal barley. bip also exhibited malformations in leaves, such as narrow leaf due to underdeveloped leaf blade width, and reduced trichome density. Map-based cloning and expression analysis indicated that BIP is identical to another barley WOX3 gene, named HvWOX3. The bip nld1 double mutant presented a more severe reduction in leaf blade width and number of trichomes. By comparing the phenotypes and gene expression patterns of various WOX3 mutants, we concluded that leaf bilateral outgrowth and trichome development are promoted by both NLD1 and HvWOX3, but that HvWOX3 serves unique and pivotal functions in barley development that differ from those of NLD1.

“…WOX genes have been identified and studied in many plants [47][48][49][50]. Phylogenetic analysis showed that the 63 WOX genes were divided into three clades, ancient, intermediate, and modern (Figure 3), and this result was consistent with the results in Brassica napus [51], Panax ginseng [52], and Rosa rugosa.…”

The WUSCHEL−related homeobox (WOX) family is a group of plant−specific transcription factors that play important regulatory roles in embryo formation, stem cell stability, and organogenesis. To date, there are few studies on the molecular mechanisms involved in this family of genes in response to stress. Thus, in this study, eight WOX genes were obtained from an endemic Chinese resilient tree species, Populus × xiaohei T. S. Hwang et Liang. Bioinformatic analysis showed that the WOX genes all contained a conserved structural domain consisting of 60 amino acids, with some differences in physicochemical properties. Phylogenetic analysis revealed that WOX members were divided into three evolutionary clades, with four, one, and three members in the ancient, intermediate, and modern evolutionary clades, respectively. The conserved structural domain species as well as the organization and gene structure of WOX genes within the same subfamily were highly uniform. Chromosomal distribution and genome synteny analyses revealed seven segmental−duplicated gene pairs among the PsnWOX gene family that were mainly under purifying selection conditions. Semi−quantitative interpretation (SQ−PCR) analysis showed that the WOX gene was differentially expressed in different tissues, and it was hypothesized that the functions performed by different members were diverse. The family members were strongly and differentially expressed under CdCl2, NaCl, NaHCO3, and PEG treatments, suggesting that WOX genes function in various aspects of abiotic stress defense responses. These results provide a theoretical basis for investigating the morphogenetic effects and abiotic stress responses of this gene family in woody plants.

“…CR-wox1-1 plants showed narrower leaves (Figures 4B and 4C) and lower LVD than M82 (Figure 4D), matching the phenotype described in wox1 mutants in other species 18,19 and tomato mutants, unfused flower (uf), and SlLAM1. [21][22][23] We noticed that these phenotypes were similar to those of the classical tomato mutant, solanifolia (sf). sf is known to have narrower leaflets and reduced vascular density, 24 and our rough mapping of the sf mutation identified a genomic location close to that known for the WOX1 locus (at the end of chromosome 3; Figure S4A).…”

“…Leaves of bip and sf double mutants are more complex than those of wox1 and narrower than those of bip3, confirming that SF promotes secondary leaflet formation, as suggested by previous studies. [21][22][23] Moreover, the double mutant showed low LVD. A recent study suggested that the regulation of local growth and differentiation in leaf primordia leads to diversity in leaf shape.…”

“…WOX1 is expressed in leaf primordia and is involved in leaf lamina expansion in various plant species, including tomato. [18][19][20][21][22][23] In the Medicago truncatula wox1 mutant, leaf vein density was lower than that in the wild type (WT). 19,23 Therefore, Sl WOX1 is likely to be a candidate gene for controlling both leaflet width and leaf vein density in the tomato.…”
