“…However, this mutant had a lower leaf area and root, shoot and whole plant dry weight, as well as a lower accumulation of N, P, K, Ca and Mg in the shoots and whole plant compared with the WT (Table 1 and 2). These results provide evidence that fri has an altered nutritional mechanism based on the interaction between phyA and S. In accordance with this, the transcription factor LONG HYPOCOTYL 5 (HY5), which acts downstream of phyA in Arabidopsis (Ang et al, 1998;Ulm et al, 2004), is involved in the regulation of adenosine 5'-phosphosulphate reductase (APR), a key enzyme for sulfate assimilation (Lee et al, 2011;Huseby et al, 2013). Thus, our results reinforce the idea that phyA plays a role in light signaling in S nutrition, but how this is achieved remains unknown.…”

The far red light insensitive (fri) mutant of tomato, which is phytochrome A (phyA) deficient, displays some characteristics that have recently indicated important functions of this photoreceptor in water relations. With respect to the relationship between nutrition and water relations, we investigated the growth and nutritional status of fri supplied with Hoagland's complete solution and solutions with the individual omission of nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg) and sulfur (S). For this purpose, 20-day-old tomato plants of the WT (cv. Moneymaker) and fri mutant were transplanted into pots (one plant per pot) that contained Hoagland and Arnon (1950) solution diluted to 50 per cent in the first week and to 100 per cent from the second week of cultivation until the end of the experiment (50 DAT O) from a balanced nutrient solution. The experiment was arranged in a completely randomized factorial design with two genotypes and seven types of nutrient solutions with three replications. Upon harvest, the following measurements were performed: the height of the plants, measured from the base of the stem of each plant to the insertion of the first fully expanded leaf; the stem diameter; the total number of leaves per plant; an indirect chlorophyll measurement, which we called the green color index, and the leaf area. Statistical analysis was performed using analysis of variance (ANOVA) followed by Tukey's test. First, based on growth analyses, fri showed an enhanced dry weight of the shoot, root and whole plant in complete solution compared with the wild type (WT). In addition, the phyA mutant had a multifaceted response compared with that of the WT when the nutrients were omitted. For the fri mutant, the height and green color index were reduced without N and K; the leaf area without P, K and S; the dry weight of the root and shoot without N, P, K and S, and the root, shoot and total plant dry weight without P, K and S. On the other hand, the green color index of the fri mutant was enhanced without Ca and Mg. Together, these results show that in addition to revealing an altered response to nutrition in the fri mutant, phyA can play a role in light signaling in the nutrition and nutritional stress of tomato.

In comparison with other cruciferous vegetables, horseradish has rarely been the object of scientifi c research, and the knowledge about the composition, content and distribution of glucosinolates (GLS) in different organs of horseradish plants is limited. Therefore, the aim of this study was to evaluate changes in the GLS content in leaves and roots of four horseradish landraces during the growing season.The presence of 13 GLS was determined in the examined horseradish tissues, and glucoraphanin, glucoraphenin and napoleiferin were noted for the fi rst time in the species. During the growing season, the content of individual GLS changed signifi cantly. The rate and direction of these changes varied across the examined landraces and plant organs. In the leaves, between May and June, the content of sinigrin, the main GLS in all horseradish landraces, decreased in Bavarian (40%) and Hungarian (11%) horseradish, increased (22%) in Creamy horseradish, whereas in Danish horseradish, the difference was not signifi cant. Despite the changes observed in the fi rst two months, the highest content of sinigrin was noted in July in all horseradish landraces. During the growing season (August-October), the content of sinigrin fl uctuated in the roots of Creamy and Danish landraces, reaching the highest level in October and September, respectively, whereas in the roots of Hungarian and Bavarian landraces, sinigrin concentrations continued to increase and peaked in October. Changes in the content of other, minor GLS during the growing season often differed from those noted in sinigrin levels.

“…This was also observed for the aliphatic glucosinolates, sinigrin and glucoraphanin, at 15/9°C in the present study as well as for some of the indolic and the aromatic glucosinolate. A negative effect of a 24 h light period on glucosinolates may be linked to the lack of circadian rhythm, which is involved in the regulation of glucosinolates in Arabidopsis (Huseby et al, 2013). The effect of day length in our Table 3 Content and composition of fatty acid in kale grown under four different day length and temperature conditions, without and with a subsequent cold acclimatisation period (mg/g dw, 95% confidence interval in brackets study seems to be dependent upon growth temperature, since several of the effects of photoperiod were only found at either high or low growth temperature.…”
