“…In woody plants, only a few genes that regulate adventitious rooting have been identified (Legue et al 2014) and mainly encoded transcription factors (TFs). In apple, the Adventitious Rooting Related Oxygenase-1 (ARRO-1) gene was isolated as an up-regulated gene from auxin-treated stem discs of the 'Jork 9' rootstock (Butler and Gallagher 1999), but it may be involved in auxin homeostasis rather than rooting (Smolka et al 2009;Li et al 2012).…”

“…The ARRO-1 gene is involved in adventitious rooting in Malus (Smolka et al 2009). Although it was upregulated under indole-3-acetic acid treatment in comparison with control stem discs, indole-3-acetic acid treatment failed to induce any adventitious roots from two rootstock materials, suggesting that it is responsible for auxin homeostasis but not for rooting (Li et al 2012).…”

Vegetative propagation enables the multiplication of plants that are genetically identical to the original. Hardwood cuttings have a low cost advantage and are used widely for the propagation of JM series apple rootstocks, which root well from hardwood cuttings. To breed new apple rootstocks with similarly high rooting capabilities, the development of a marker-assisted selection method is desirable. Therefore, it is important to understand the genetic mechanisms behind the rooting capabilities of hardwood cuttings. We identified quantitative trait loci (QTLs) for the rooting capability of 'JM7' using a QTL analysis with phenotypic data obtained under two environmental conditions. The QTLs for rooting rate and root quantity co-located. The QTL for rooting rate explained 66 % of the genetic variance and 57 % of the phenotypic variance. Graphical genotyping and database searching revealed candidate genes, including three related to auxin response, one related to ethylene response, and a gene encoding a WRKY transcription factor.

“…Some elite varieties of woody species, like apple, eucalypt, and pine, are difficult to root and therefore cannot be exploited as a commercial product. Because of commercial interest, several studies on apple (Ricci et al, 2001;Naija et al, 2008;Smolka et al, 2009), eucalypt (Fett-Neto et al, 2001Schwambach et al, 2005) and loblolly pine (Greenwood et al, 2001;Rasmussen and Hunt, 2010) have been conducted. However, the number of molecular studies of the rooting process in these species is very limited and most studies have focussed on techniques that promote adventitious rooting.…”

“…The Adventitious Rooting Related Oxygenase1 was shown to be strongly induced by IBA and IAA but not 2,4-D during adventitious rooting and also in the primary roots of apple seedlings. It is suggested to act by regulating hormone homoeostasis (Smolka et al, 2009). In poplar, the CK type B response regulator Ptrr13, a transcription factor that acts as positive regulator in the cytokinin signalling pathway, has been shown to negatively regulate AR (Ramı´rez-Carvajal et al, 2009), whereas the transcription factor Ptail1 is a positive regulator (Rigal et al, 2012).…”

The root system of a plant is composed of the primary, lateral and adventitious roots (ARs). Lateral roots always develop from roots, whereas ARs form from stem or leaf‐derived cells. AR formation is part of the normal development of the plant and occurs naturally, like in most monocotyledonous for which they constitute the main root system or in many dicotyledonous species that propagate vegetatively. Adventitious rooting is an essential step for vegetative propagation of economically important horticultural and woody species as it allows clonal propagation and rapid fixation of superior genotypes prior to their introduction into production or breeding programmes. Development of ARs is a complex process that is affected by multiple endogenous and environmental factors, including phytohormones; light; nutritional status; associated stress responses, such as wounding; and genetic characteristics. Key Concepts: ARs are the main root system for monocots. ARs are an adaptative response to environmental changes. ARs are required for vegetative propagation of plants. ARs arise from any organ of the plant but the root. ARs originate from different cell types depending on the organ or the species. ARs can be induced by ECMs or Agrobacterium rhizogenes . ARdevelopment is controlled by environmental factors. Adventitious rooting is an age‐dependant process. Auxin cross talks with other hormones to control adventitious rooting. Adventitious rooting is a complex quantitative genetic trait.

“…Almond (Costa et al, 2006); apple (Smolka et al 2009;Lau & Korban, 2010;Vanblaere et al, 2011); banana (Subramanyam et al, 2011); fig (Yancheva et al, 2005); kiwifruit (Tian et al, 2011); peach (Padilla et al, 2006); strawberry (Mercado et al, 2010); peanut (Asif et al, 2011); watermelon (Huang et al, 2011) and pear (Sun et al, 2011) are some examples of transformed cultivars for some fruit species that the transformed tissues were regenerated via organogenesis. Since organogenesis protocols are developed for many different fruit species, it is easier to adapt the regeneration system into genetic transformation methods (Frary & Eck, 2005).…”
