“…Cultivar 'Laird' from macrosperma was cultured on medium containing 25-500 fM, PAA but habituation of cultures was common. PAA was not toxic to lentil tissues at concentration as high as 500 fM (Leuba and LeTourneau, 1990). In lentil, excised root tips showed elongation in sucrose medium, pH 5.2.…”

In vitro growth responses of various lentil genotypes varied. The best callussing response was noticed in variety ILL-4605. The genotype AARI-L-89503 had a tendency for embryogenesis. The genotype AARI-L-86642 had the best rooting ability. This genotype also showed in vitro flowering response. Masoor-85 and Pant-L-406 had moderate morphogenic responses, Meristem multiplication, shoot development, shoot bud formation from callus and adventitious rooting from shoot cuttings was obtained under appropriate growth regulators combinations.

“…Phenylacetic acid (PAA) and p-OH-PAA are common plant metabolites and can be synthesized directly from L-Phe and L-Tyr respectively (Camirand et al, 1983). The activity of PAA and p-OH-PAA is auxin-like, although less so than IAA (Wightman & Lightly, 1982 ;Leuba & Le Tourneau, 1990). In Lepidium sativum, a cruciferous species susceptible to infection with P. brassicae, an absence of indole glucosinolates but the presence of benzylglucosinolate have been detected ; and it was therefore speculated that benzylglucosinolate could serve as a precursor for PAA (Fig.…”

The host range of Plasmodiophora brassicae and its relationship to endogenous glucosinolate content

et al. 1999

The host range of the soilborne obligate biotroph, Plasmodiophora brassicae was investigated. Evidence is presented that infection by P. brassicae might occur in non-Brassica species, leading to the potential formation of resting spores. Structures resembling P. brassicae were found in the root cortex of Tropaeolum majus, Carica papaya, Reseda alba and Beta vulgaris as demonstrated by scanning electron microscopy. Inoculation of Brassica rapa roots with spores extracted from either T. majus or B. vulgaris roots which had been previously inoculated with P. brassicae led to development of clubroot in the roots of B. rapa. It was also shown that the development of the symptom might be correlated with glucosinolate content, although other host factors are implicated in the B. vulgaris interaction with P. brassicae. In the glucosinolate-containing non-Brassicas, T. majus and C. papaya, the concentrations of benzylglucosinolate increased markedly in roots inoculated with P. brassicae, compared with the controls. There were also increases in concentrations of benzylglucosinolate in leaves of T. majus after P. brassicae infection. However, in R. alba roots, the total glucosinolate content decreased after inoculation with P. brassicae compared with the controls. High root concentrations of 2-OH-2-phenylethylglucosinolate (glucobarbarin) compared with low root indole glucosinolates in this species might limit P. brassicae infection and development. The importance of our investigations in relation to cultivation of non-Brassica species on fields infested with P. brassicae is discussed.

Several new N-containing epiandrosterone derivatives modified by phenylacetic acid chloride were synthesized for biological activity studies. Compounds with antiviral activity were discovered among them and 3E-hydroxy-1c-aryl-3c-methyl-5D-androstano[17,16-d]pyrazolines prepared by us earlier.Syntheses of biologically active oximes, hydrazones, or carbazones of steroidal ketones have been the subject of much research [1][2][3][4].

Steroidal esters of phenylacetic-acid derivatives exhibited characteristic antitumor activity [10]. The drug perandren is a phenylacetate ester of testosterone that is used for osteoporosis, breast cancer, etc.The structure-activity relationship was studied using esterification of epiandrosterone (1) by phenylacetic acid chloride to produce modified ketone 2. Reactions of 2 with hydroxylamine, m-nitrobenzoic or nicotinic acid hydrazides, and semi-or thiosemicarbazides synthesized derivatives 3-7.
