Special Issue Information

Dear Colleagues,

Adventitious root formation is a key step in vegetative propagation by stem cuttings. In addition, it is involved in planted seedling adaptation to growing conditions in many tree species. Adventitious rooting can be induced in stem cuttings or in intact seedlings. The mechanisms underlying this complex process are not well-characterized but imply a switch of the progenitor cell identity to become a root meristem. In tree species, adventitious root formation is regulated at different levels: Genetic, developmental, or environmental factors affect the adventitious rooting capacity and may limit the use of clonal propagation to capture the genetic superiority of a selected individual, or the success of the adaptation to new growing conditions in operational forest planting programs. The knowledge of the cellular and molecular regulation of adventitious root formation offers the possibility of selecting genotypes for clonal propagation and developing new methods for propagation of physiologically mature trees which have been selected based on yield traits as well as allows characterizing the physiological advantage provided to seedlings by adventitious roots in planting sites subjected to stress environmental conditions. Current research on adventitious root formation and function is quite broad, ranging from field studies to the physiological, molecular or cellular level. Recently, remarkable progress has been made in the mechanisms underlying adventitious rooting through the application of the cutting-edge tools of genome and proteome analysis, which provides a comprehensive picture of the genes and cellular processes involved in many aspects of root induction and development. The integration of this information is creating models of root induction, which are providing valuable information about the process. The knowledge obtained in these studies points the way forward for strategies aimed at enhancing the quantity and quality of roots for desired end-uses. The challenge is to ensure that the investment that has been made in basic research truly adds value to economically or ecologically important species. In this spirit, this Special Issue intends to describe the state-of-the-art in adventitious root induction and development in trees, including both applied and basic studies, as well as the effect of factors limiting rooting capacity by stem cuttings or intact seedlings from many tree species.

The rooting of stem cuttings is a highly efficient procedure for the vegetative propagation of ornamental plants. In cultivated carnations, an increased auxin level in the stem cutting base produced by active auxin transport from the leaves triggers adventitious root (AR) formation from the cambium. To provide additional insight into the physiological and genetic basis of this complex trait, we studied AR formation in a collection of 159 F1 lines derived from a cross between two hybrid cultivars (2003 R 8 and 2101-02 MFR) showing contrasting rooting performances. In three different experiments, time-series for several stem and root architectural traits were quantified in detail in a subset of these double-cross hybrid lines displaying extreme rooting phenotypes and their parental genotypes. Our results indicate that the water content and area of the AR system directly contributed to the shoot water content and shoot growth. Moreover, morphometric data and rooting quality parameters were found to be associated with some stress-related metabolites such as 1-aminocyclopropane-1-carboxylic acid (ACC), the ethylene precursor, and the conjugated auxin indol-3-acetic acid-aspartic acid (IAA-Asp).
