Eucalyptus is an important industrial species with tolerance to drought and salt stress. Genetic improvement activities including quantitative trait loci (QTL) mapping for pulping and adventitious rooting traits are in progress, but no information is available on the genomic regions on adaptive traits such as stomatal characteristics. In this study, an interspecific cross between Eucalyptus tereticornis and E. grandis was generated for the development of genetic map and QTL identification for stomatal traits...

Adventitious roots (ARs) emerge from stems, leaves or hypocotyls, being strategic for clonal propagation. ARs may develop spontaneously, upon environmental stress or hormonal treatment. Auxins strongly influence AR development (ARD), depending on concentration and kind. However, the role of different types of auxin is rarely compared at the molecular level. Rooting triggered by light exposure and flooding was examined in intact etiolated Arabidopsis thaliana hypocotyls treated with distinct auxin types. Morphological aspects, rooting-related gene expression profiles, and IAA immunolocalization were recorded...

Root formation under natural conditions is plastic in response to multiple signals. Recent studies suggested that the WUSCHEL-RELATED HOMEOBOX11 (WOX11)-mediated adventitious root (AR) formation pathway can occur in the primary root (PR) in Arabidopsis thaliana, resulting in the production of a specific type of lateral roots (LRs) in response to wounding or environmental signals. This process differs from the previously characterized process for LR development, which does not require WOX11. The WOX11-mediated PR-derived roots can be considered like LRs that exhibit an "adventitious" feature...

The interplay between myosin- and auxin-mediated processes was investigated by following root development in the triple myosin knockout mutant xi-k xi-1 xi-2 (3KO). It was found that the 3KO plants generated significantly more lateral and adventitious roots than the wild type plants or rescued plant line expressing functional myosin XI-K:YFP (3KOR). Using the auxin-dependent reporter DR5:venus, a significant change in the auxin gradient toward the root tip was found in 3KO plants, which correlated with the loss of polar localization of the auxin transporter PIN1 in the stele and with the increased number of the stele cells with oblique cell walls...

Flooding negatively affects the growth and even survival of most terrestrial plants. Upon flooding, the excess water quickly decreases the gas exchange between atmosphere and the submerged plant tissues, which leads to oxygen deficiency resulting in a plant cell energy crisis, and eventually plant death. Solanum dulcamara survives flooding by producing aerenchymatous adventitious roots (ARs) from pre-formed primordia on the stem, which replace the original flood-sensitive root system. However, we found that under complete submergence, AR outgrowth was impaired in S...

Black spruce (Picea mariana (Mill.) BSP) is a boreal tree species characterized by the formation of an adventitious root system. Unlike initial roots from seed germination, adventitious roots gradually appear above the root collar, until they constitute most of mature black spruce root system. Little is known about the physiological role they play and their influence on tree growth relative to initial roots. We hypothesized that adventitious roots present an advantage over initial roots in acquiring water and nutrients...

Andrographolide (AD) is the time-honoured pharmacologically active constituent of the traditionally renowned medicinal plant-Andrographis paniculata. Advancements in the target-oriented drug discovery process have further unravelled the immense therapeutic credibility of another unique molecule-neoandrographolide (NAD). The escalated market demand of these anti-cancer diterpenes is increasingly facing unrelenting hurdles of demand and supply disparity, attributable to their limited yield. Callus and adventitious root cultures were generated to explore their biosynthetic potentials which first time revealed NAD production along with AD...

Adventitious roots (AR) are de novo formed roots that emerge from any part of the plant or from callus in tissue culture, except root tissue. The plant tissue origin and the method by which they are induced determine the physiological properties of emerged ARs. Hence, a standard method encompassing all types of AR does not exist. Here we describe a method for the induction and analysis of AR that emerge from the etiolated hypocotyl of dicot plants. The hypocotyl is formed during embryogenesis and shows a determined developmental pattern which usually does not involve AR formation...

Tissue identity is plastically regulated in plants, and chromatin modifiers/remodelers are main players of cell fate changes. Callus formation is an intriguing example of cell fate transition. Leaf explants can form callus tissues, which resemble lateral root primordium, on callus-inducing medium (CIM). We recently demonstrated that the ARABIDOPSIS TRITHORAX-RELATED 2 (ATXR2) protein, which deposits H3K36me3 at genomic level, regulates callus formation on CIM. Consistent with the role of ATXR2 in conferring root identity, lateral root formation was significantly reduced in atxr2-deficient mutants...

Adventitious root (AR) formation, which is controlled by endogenous and environmental factors, is indispensable for vegetative asexual propagation. However, comprehensive proteomic data on AR formation are still lacking. The aim of this work was to study indole-3-butyric acid (IBA)-induced AR formation in the dwarf apple rootstock 'T337'. In this study, the effect of IBA on AR formation was analysed. Subsequent to treatment with IBA, both the rooting rate and root length of 'T337' increased significantly. An assessment of hormone levels in basal stem cuttings suggested that auxin, abscisic acid, and brassinolide were higher in basal stem cuttings that received the exogenous IBA application; while zeatin riboside, gibberellins, and jasmonic acid were lower than non-treated basal stem cuttings...

Propagation of some Olea europaea L. cultivars is strongly limited due to recalcitrant behavior in adventitious root formation by semi-hardwood cuttings. One example is the cultivar "Galega vulgar". The formation of adventitious roots is considered a morphological response to stress. Alternative oxidase (AOX) is the terminal oxidase of the alternative pathway of the plant mitochondrial electron transport chain. This enzyme is well known to be induced in response to several biotic and abiotic stress situations...

While the characterization of the biosynthetic pathway of monoterpene indole alkaloids (MIAs) in leaves of Catharanthus roseus is now reaching completion, only two enzymes from the root counterpart dedicated to tabersonine metabolism have been identified to date, namely tabersonine 19-hydroxylase (T19H) and minovincine 19-O-acetyltransferase (MAT). Albeit the recombinant MAT catalyzes MIA acetylation at low efficiency in vitro, we demonstrated that MAT was inactive when expressed in yeast and in planta, suggesting an alternative function for this enzyme...

Adventitious roots (ARs) of lotus (Nelumbonucifera Gaertn.) play a critical role in water and nutrient uptake. We found that exogenously applied 10-μM indole-3-acetic acid (IAA) promoted the formation of ARs, while 150-μM IAA significantly inhibited the emergence of ARs. However, little is known about these different responses to various concentrations of IAA at the molecular level. This study, therefore, examined the gene expression profiling in four libraries treated with 10- and 150-μM IAA based on the high-throughout tag sequencing technique...

Background and Aims: Information on cell cycle duration (T) in the root apical meristem (RAM) provides insight into root growth, development and evolution. We have previously proposed a simple method for evaluating T based on the dynamics of root growth (V), the number of cells in the RAM (Nm) and the length of fully elongated cells (l), which we named the rate-of-cell-production (RCP) method. Here, a global analysis was performed to confirm the reliability of this method in a range of angiosperm species and to assess the advantages of this approach...

Tamarix aphylla (L.) Karst., a drought resistant halophyte tree, is an agroforestry species which can be used for reclamation of waterlogged saline and marginal lands. Due to very low seed viability and unsuitable conditions for seed germination, the tree is becoming rare in Indian Thar desert. Present study concerns the evaluation of aeroponics technique for vegetative propagation of T. aphylla. Effect of various exogenous auxins (indole-3-acetic acid, indole-3-butyric acid, naphthalene acetic acid) at different concentrations (0...

Cutting propagation plays a large role in the forestry and horticulture industries where superior genotypes need to be clonally multiplied. Integral to this process is the ability of cuttings to form adventitious roots. Recalcitrance to adventitious root development is a serious hurdle for many woody plant propagation systems including black walnut (Juglans nigra L.), an economically valuable species. The inability of black walnut to reliably form adventitious roots limits propagation of superior genotypes...

Biotic elicitation is an important biotechnological strategy for triggering the accumulation of secondary metabolites in adventitious root cultures. These biotic elicitors can be obtained from safe, economically important strains of bacteria found in the rhizosphere and fermented foods.

In plants, the formation of hypocotyl-derived adventitious roots (ARs) is an important morphological acclimation to waterlogging stress; however, its genetic basis remains fragmentary. Here, through combined use of bulked segregant analysis-based whole-genome sequencing, SNP haplotyping and fine genetic mapping, we identified a candidate gene for a major-effect QTL, ARN6.1, that was responsible for waterlogging tolerance due to increased AR formation in the cucumber line Zaoer-N. Through multiple lines of evidence, we show that CsARN6...

The growth performance of Salix triandroides cuttings at three water cadmium (Cd) concentrations (0, 20, and 40 mg L-1 ) and three water levels (- 40 cm, water level 40 cm below the soil surface; 0 cm, water level even with the soil surface; and 40 cm, water level 40 cm above soil surface) was investigated to evaluate its potential in phytoextraction strategies. Compared to cuttings in the - 40 or 0 cm water levels, cuttings in the 40 cm water level showed significantly lower biomass, height, and adventitious root length and significantly fewer leaves and adventitious roots...
