“…Seedling growth was affected by the concentration of AIP: AIP5 seedlings were affected least while AIP15 and AIP30 seedlings were equally affected, except for AIP30 seedling roots, which showed the greatest reduction. In previous studies, AIP reduced (Reuber et al 1993;Janas et al 1998), increased (Gitz et al 1998;Ruuhola and Julkunen-Tiitto 2003), or had no effect (Ruuhola and Julkunen-Tiitto 2000;Janas et al 2002) on the growth of experimental plants.…”

“…The few cases in which AIP did not affect the amounts of individual phenolics include phenolic glycosides (salicylates) in leaves of Salix which were mature before the addition of AIP to the growing medium Julkunen-Tiitto 2000, 2003), and sinapic acid esters in the cotyledons of Brassica oleraceae rubrum seedlings grown from seeds rich in these compounds (Gitz et al 1998). The effect of AIP on the growth of plants has been more variable, showing increases (Gitz et al 1998;Ruuhola and Julkunen-Tiitto 2003), decreases (Reuber et al 1993;Janas et al 1998) and no effect at all (Ruuhola and Julkunen-Tiitto 2000;Janas et al 2002).…”

We studied phenolic metabolism and plant growth in birch seedlings at the beginning of their development by inhibiting phenylalanine ammonia lyase (PAL), which is the first committed step in phenylpropanoid metabolism. Betula pubescens (Ehrh.) seeds were germinated in inhibitor-free media and the seedlings were transferred to hydroponic culture at the cotyledon stage. They were 6 days old at the start of the experiment, which lasted for 3 weeks. PAL activity was inhibited by three different concentrations of 2-aminoindane-2-phosphonic acid monohydrate (AIP) in the growing media. At the end of 3 weeks, phenolics in all plant parts (roots, stem, cotyledons, first, second and third true leaves) were determined. AIP inhibited strongly the accumulation of phenolic acids, salidroside, rhododendrins, ellagitannins and their precursors, flavan-3-ols, and soluble condensed tannins. The accumulation of lignin and flavonol glycoside derivatives was moderately inhibited. The accumulation of flavonol glycosides, such as quercetin glycosides and kaempferol glycosides, was not generally inhibited, even in leaves that emerged during the experiment, while the accumulation of insoluble condensed tannins was inhibited only slightly and not in all plant parts. This suggests that flavonol glycosides, which may have a UV-B protective role, and insoluble condensed tannins, which may have structural functions, are prioritized in seedling development. Inhibition of PAL with AIP decreased seedling growth and possible reasons for this are discussed.

“…Some plant growth-retarding chemicals have also been studied for their ability to promote starch accumulation in duckweed. The compound 2-aminoindan-2-phosphonic acid was reported to cause the enrichment of starch in duckweed [64]. Compared with controls, an 2-aminoindan-2-phosphonic acid concentration of 100 mM increased the starch content of S. punctata by 130% in the first 5 days and 370% during the next 3 days.…”

“…AIP has been shown to inhibit the accumulation of many kinds of phenolic compounds (Zoń and Amrhein 1992;Reuber et al 1993;Gitz et al 1998;Julkunen-Tiitto 2000, 2003). Growth responses to AIP have varied, showing decreases (Reuber et al 1993;Janas et al 1998), increases (Gitz et al 1998;Ruuhola and Julkunen-Tiitto 2003) or no effect (Ruuhola and Julkunen-Tiitto 2000;Janas et al 2002).…”

Phenylalanine ammonia lyase (PAL) plays a key role in phenylpropanoid metabolism, catalyzing the deamination of phenylalanine (Phe) to form transcinnamic acid. Inhibitors of PAL have been used to study the physiological role of the different compounds derived from trans-cinnamic acid, and to test theories about a trade-off between growth and defence in plants. In a previous study with birch (Betula pubescens Ehrh.) seedlings, the PAL inhibitor 2-aminoindane-2-phosphonic acid monohydrate (AIP) caused an accumulation of Phe and a strong decrease in the quantity of simple phenolics, soluble condensed tannins and growth, whereas flavonol glycosides were generally not affected. The present study demonstrates restoration of secondary metabolism in the previously AIP treated birch seedlings. Our results indicate that Phe accumulated during PAL inhibition could be partly used to increase the content of the phenolic acids, flavan-3-ols and to some extent the soluble condensed tannins. Seedling growth also increased when the supply of PAL inhibitor ceased. We thereby show that the inhibition of PAL by AIP in vivo is reversible, at least for moderate AIP concentrations and the rate of restoration is dependent on the inhibitor concentration.
