“…The shallower roots and greater percentage of roots close to the surface in SHB seedlings (family P2) compared with V. arboreum seedlings (family P3) are the first set of empirical evidence documenting RSA differences between plants in these two taxa grown under the same conditions. These results are in agreement with previous reports based on field observations (Lyrene, 1991;Lyrene and Brooks, 1995). Water acquisition from subsoil strata through a deeper root system is likely the reason for the reported drought-tolerance of V. arboreum plants (Stockton, 1976).…”

“…This species can withstand growth in higher pH (up to pH 6.4) and mineral, drought-prone soils (Stockton, 1976). In addition, V. arboreum plants exhibit greater capacity for nitrate uptake than SHB plants (Poonnachit and Darnell, 2004), andaccording to field-level observations-V. arboreum plants develop deep, taproot-like root systems (Lyrene and Brooks, 1995). Although there is a lack of quantitative data about the roots of SHB and V. arboreum plants grown under the same conditions, deeper root systems in other species have been shown to confer an adaptive advantage in soils where water (Padilla and Pugnaire, 2007;Pinheiro et al, 2005) and nitrate (Gastal and Lemaire, 2002;King et al, 2003) percolate to deeper horizons.…”

Root growth and root system architecture (RSA) are affected by edaphic and genetic factors and they can impact plant growth and farm profitability. Southern highbush blueberries [SHBs (Vaccinium corymbosum hybrids)] develop shallow, fibrous root systems, and exhibit a preference for acidic soils where water and ammonium are readily available. The amendments used to create these soil conditions negatively affect the profitability of SHB plantations. Hence, breeding for RSA traits has been suggested as an alternative to soil amendments. Vaccinium arboreum is a wild species that is used in SHB breeding. V. arboreum exhibits greater drought tolerance and broader soil pH adaptation than SHB, and—according to anecdotal evidence—it develops deep, taproot-like root systems. The present study constitutes the first in-depth study of the RSA of Vaccinium species with the intention of facilitating breeding for RSA traits. Root systems were studied in rhizotron-grown seedling families. In separate experiments, we tested the effect that growth substrate and family pedigree can have on root growth and RSA. Subsequently, a genotyping by sequence approach was used to develop single nucleotide polymorphism (SNP) markers that could be used along with the phenotyping method to investigate the heritability of RSA traits and look for marker-trait associations. We found that RSA is affected by growth substrate and family pedigree. In addition, we found that V. arboreum exhibited greater maximum root depth and a lower percentage of roots in the top 8 cm of soil than SHB, and interspecific hybrids generally exhibited intermediate phenotypes. Also, we found that RSA traits exhibit moderate to low heritability and genetic correlations among them. Finally, we found 59 marker-trait associations. Among these markers, 37 were found to be located in exons, and 16 of them were annotated based on protein homology with entries in National Center for Biotechnology Information (NCBI) GenBank. Altogether, the present study provides tools that can be used to breed for root architecture traits in SHB.

“…The failure of both VA and SHB to acidify the nutrient solution and the gels suggests that the wider soil adaptation of VA compared with SHB (Hancock et al, 2008;Lyrene, 1997;Lyrene and Brooks, 1995) is not related to the former species' capacity to create an acidic microenvironment around its roots. It is tempting to propose that these and other Vaccinium sp.…”

“…It is tempting to propose that these and other Vaccinium sp. might have lost the ability to acidify their rhizosphere because this trait does not confer a selective advantage in the generally acidic soils where they are found in the wild and in cultivation (Coville, 1910;Finn et al, 1993;Lyrene, 1997;Lyrene and Brooks, 1995). In acidic soils, relaxed selection (Lahti et al, 2009) on rhizosphere acidification could have led to the reduction or disappearance of this trait in Vaccinium sp.…”

Vaccinium arboreum (VA) is a wild blueberry species that exhibits wider soil pH tolerance and greater ability for iron and nitrate uptake than cultivated Vaccinium species, including southern highbush blueberry (SHB, V. corymbosum interspecific hybrids). The ability of VA and SHB to respond to iron deficiency by rhizosphere acidification was investigated. Rooted cuttings of the VA genotype FL09-502 and SHB ‘Emerald’ were transplanted to a hydroponic system filled with complete nutrient solution. After 14 days of acclimation at 45 µm iron, plants were transferred to unbuffered nutrient solutions containing 90 or 10 µm iron. ‘Emerald’ and FL09-502 plants grown in 10 µm iron exhibited less iron uptake and lower chlorophyll, total iron, and active iron contents than plants grown in 90 µm iron. Generally, there were no species-level differences in iron or nitrate uptake. Neither FL09-502 nor ‘Emerald’ acidified the rhizosphere in either the nutrient solution or in a gel-based assay, regardless of external iron concentration. A screen of 18 additional genotypes of VA and SHB confirmed that this response is absent in these taxa. Thus, rhizosphere acidification is not part of the iron deficiency response of SHB and VA. In addition, the ability to acidify the soil is not likely to be responsible for the wider soil pH tolerance of VA.

“…Over the last 20 years, serious concerns have been raised over the very restricted germplasm base in commercially important cultivars of the various cultivated Vaccinium crops (Galletta and Ballington, 1996), and breeders have made conscious efforts to broaden this base in recent cultivar releases (Ballington, 1990;Ehlenfeldt, 1997;Hancock et al, 1995;Lyrene, 1988;Lyrene and Brooks, 1995). However, continuing and increased efforts are needed, particularly in broadening cytoplasmic diversity (Hancock and Krebs, 1986).…”

Vaccinium L. is one of the major genera in the tribe Vacciniae of the subfamily Vaccinoiodae of the Ericaceae (Stevens, 1969). The Vacciniae include all the Ericaceae with inferior ovaries, and are also typically characterized as having fleshy, more-or-less edible fruits commonly referred to as "blueberries," even though in a number of species the fruits are not blue. The genus includes ≈400 species worldwide, and occurs on all continents except Antarctica and Australia (Luby et al., 1991). It also includes cranberries, bilberries, lingonberries, whortleberries, deerberries, and species referred to by any number of other common names in various parts of the world. Some species of Vaccinium are also commonly called huckleberries, but this name is more properly applied to species in the very closely related genus Gaylussacia L. The genus includes 30 sections (subgenera) as currently circumscribed (Stevens, 1969). Fruit harvested from wild populations of Vaccinium species have made significant contributions to the human diet for thousands of years (Darrow and Camp, 1945; Hunn and Norton, 1983). Native stands of several species have been managed for fruit production for at least 1000 years, especially the lowbush blueberry, in New England, the upper midwest, and eastern Canada in North America (Hall et al., 1979; Yarborough, 1997). Three commercial cultivated fruit crops have been developed from species and species hybrids in Vaccinium. These include: the cultivated and semi-cultivated blueberries, derived from species in Vaccinium section Cyanococcus A. Gray, from eastern North America; the large or American cranberry, developed from V. macrocarpon Ait. (2n = 2x = 24), a North American species in section Oxycoccus (Hill) Koch; and the lingonberry, V. vitis-idaea L. (2n = 2x = 24), in section Vitis-idaea (Moench) Koch, a circumboreal species (Galletta and Ballington, 1996). The recent introduction of cultivars of the tetraploid
