Conversely, for nutrient uptake, ideotypes differing in root depth, number and angle were recommended for immobile nutrients such as phosphorus, which are dominantly located in the cultivated layer of soil, and for nutrients easily soluble in the soil solution and more prone to leaching and diffusion in the profile such as nitrogen (Lynch and Brown, 2001; White et al. 2013).
Differential expression of other carotenogenic genes does not seem to be required to drive carotenoid overproduction, as can be concluded from comparative transcriptional analysis conducted with several carrot cultivars differing in root color [32].
Two mulberry genotypes viz., Dudia white and UP105 were identified as contrasting lines differing in root traits and WUE in earlier studies [ 50].
An expression analysis of the carotenoid biosynthetic genes suggested that their expression levels differed in root, stem, leaf, flower, callus, and silique tissues.
In the absence of mannitol, WT and OsADF3-OE transgenic plants did not differ in root growth (Figure 7(c) and (d)); however, at 300 mM mannitol, the primary root growth was inhibited to about 40% in transgenic lines and to about 60% in WT plants.
This study validated the mtLSU markers to detect/trace and quantify AMF inoculants as native strains in plants grown under field conditions and further supported that potato cultivars in the same field conditions differed in root colonization.
Sensitivity to BFA also differed between root cells.
In the dark, however, none of the lines significantly differed in root length from that of wild-type.
Because the WT and ethylene signaling mutants differ in root and shoot lengths even under control conditions, absolute length comparisons under phenanthrene treatment are not meaningful between genotypes.
Seeds of this species have a special kind of MPD, called epicotyl dormancy, in which temperature requirements differ for root emergence (and prior embryo growth) versus shoot emergence as well as temporally (Giersbach 1937; Knowles and Zalik 1958; Zolobova 1970; Fedec and Knowles 1973).
