“…WUS is a member of the WUSCHEL-RELATED HOMEOBOX (WOX) family, which also includes 14 other genes in Arabidopsis (WOX1-WOX14) that are involved in various developmental processes in plants [90,91]. They represent an old phylogenetic group of regulatory genes that diverged before the diversification of vascular plants, with highly conserved regulatory elements suggesting that their regulation by auxin and CK is ancient [92].…”

De novo shoot organogenesis (DNSO) is a procedure commonly used for the in vitro regeneration of shoots from a variety of plant tissues. Shoot regeneration occurs on nutrient media supplemented with the plant hormones cytokinin (CK) and auxin, which play essential roles in this process, and genes involved in their signaling cascades act as master regulators of the different phases of shoot regeneration. In the last 20 years, the genetic regulation of DNSO has been characterized in detail. However, as of today, the CK and auxin signaling events associated with shoot regeneration are often interpreted as a consequence of these hormones simply being present in the regeneration media, whereas the roles for their prior uptake and transport into the cultivated plant tissues are generally overlooked. Additionally, sucrose, commonly added to the regeneration media as a carbon source, plays a signaling role and has been recently shown to interact with CK and auxin and to affect the efficiency of shoot regeneration. In this review, we provide an integrative interpretation of the roles for CK and auxin in the process of DNSO, adding emphasis on their uptake from the regeneration media and their interaction with sucrose present in the media to their complex signaling outputs that mediate shoot regeneration.

“…The AtWOX14 usually affects plant growth and the formation of conductive tissues, and the deletion of AtWOX14 induces plant dwarfism ( Denis et al, 2017 ). The WOX genes of the ancient clade in other species functioned similarly to that in Arabidopsis ( Tvorogova et al, 2021 ). The intermediate clade contains four AtWOX genes ( AtWOX8 , AtWOX9 , AtWOX11 , and AtWOX12 ) ( Deveaux et al, 2008 ; Tvorogova et al, 2021 ).…”

“…Previous researches have verified that members of the WOX subfamily participate in many plant biological processes, such as the formation and maintenance of the shoot apical meristem (SAM) ( Meng et al, 2019 ). The WOX subfamily specifically binds to the target region by the homeodomain to activate or depress the expression of the target gene in plants ( Mukherjee, Brocchieri & Bürglin, 2009 ; Jha, Ochatt & Kumar, 2020 ; Tvorogova et al, 2021 ). Genome-wide identification of the WOX subfamily has been performed in several plants, including Arabidopsis, rice, maize, walnut, physic nut, grapes, peach, pear, apricot, coffee, and poplar ( Li et al, 2020 ; Shafique Khan et al, 2021 ).…”

“…The WOX gene family has often been classified into three clades which include the ancient clade, the intermediate clade, and the modern/WUS clade ( Tvorogova et al, 2021 ). Among the 15 WOX genes in Arabidopsis, AtWOX10 , AtWOX13 , and AtWOX14 belong to the ancient clade ( Tvorogova et al, 2021 ). The AtWOX10 gene is a presumptive pseudogene owing to its undetectable gene expression in Arabidopsis plants ( Deveaux et al, 2008 ).…”

The WUSCHEL (WUS)-related homeobox (WOX) gene family is a class of plant-specific transcriptional factors and plays a crucial role in forming the shoot apical meristem and embryonic development, stem cell maintenance, and various other developmental processes. However, systematic identification and characterization of the kiwifruit WOX gene family have not been studied. This study identified 17 and 10 WOX genes in A. chinensis (Ac) and A. eriantha (Ae) genomes, respectively. Phylogenetic analysis classified kiwifruit WOX genes from two species into three clades. Analysis of phylogenetics, synteny patterns, and selection pressure inferred that WOX gene families in Ac and Ae had undergone different evolutionary patterns after whole-genome duplication (WGD) events, causing differences in WOX gene number and distribution. Ten conserved motifs were identified in the kiwifruit WOX genes, and motif architectures of WOXs belonging to different clades highly diverged. The cis-element analysis and expression profiles investigation indicated the functional differentiation of WOX genes and identified the potential WOXs in response to stresses. Our results provided insight into general characters, evolutionary patterns, and functional diversity of kiwifruit WOXs.
