Allene oxide synthase (AOS) encodes the first enzyme in the lipoxygenase pathway, which is responsible for jasmonic acid (JA) formation. In this study we report the molecular cloning and characterization of InAOS from Ipomoea nil. The full-length gene is composed of 1662 bp and encodes for 519 amino acids. The predicted InAOS contains PLN02648 motif, which is evolutionarily conserved and characteristic for functional enzymatic proteins. We have shown that wounding led to a strong stimulation of the examined gene activity in cotyledons and an increase in JA level, which suggest that this compound may be a modulator of stress responses in I. nil.

W pracy badano nasiona pieprzycy siewnej o wilgotności 13%. Obłuskiwanie nasion, wykonywane na obłuskiwaczu tarczowym, następowało na skutek uderzenia o wirujące elementy robocze. Uzyskaną mieszaninę części morfologicznych nasion rozdzielano wykorzystując sita oraz separator pneumatyczny PETKUS K-293. Do analizy cech geometrycznych wybierano nasiona i liścienie niepołamane, bez widocznych uszkodzeń. Dla poszczególnych nasion i liścieni na podstawie wzorów obliczono pole powierzchni oraz objętość. Obliczono również współczynniki kształtu nasion i liścieni opierając się na wzorach Grochowicza, Mohsein’a i Donev’a. Na podstawie przeprowadzonych pomiarów i obliczeń wykazano, że średnia długość nasiona pieprzycy siewnej jest o 29% większa niż średnia długość liścieni, zaś średnia szerokość nasiona jest większa o 40% od średniej szerokości liścienia, a średnia grubość nasiona jest większa o 51% od średniej grubości liścienia. Obliczone średnie pole powierzchni nieobłuskanych nasion wynosiło 11,02 mm2 i było większe o 61% od obliczonego średniego pola powierzchni liścieni. Średnia obliczona objętość nasiona wynosiła 2,36 mm3 i była większa o 79% od średniej obliczonej objętości liścieni.

Flower buds, cotyledons and hypocotyls of Pharbitis nil were used as plant material. Flower buds (1-2 mm long) were excised from 3-week-old plants, grown in soil. Cotyledons of 7-day-old sterile seedlings were cut into 25 mm2 squares cotyledons whereas hypocotyls were cut to 1 mm long fragments. Explants were transferred into Petri dishes containing the Murashige and Skoog medium (MS), supplemented with either BA (11 μM·U⁻¹) alone or BA (22 μM·U⁻¹) and NAA (0.55 μM·U⁻¹), and different sugars: sucrose, fructose, glucose, mannose or sorbitol (autoclaved or filter-sterilized). Addition of glucose instead of sucrose to the medium stimulated the induclion of callus on flower buds and cotyledoniry explants, but inhibited its growth on fragments of hypocotyls. The medium supplemented with fructose (especially filter-sterilized) stimulated the development of flower elements. Organogenesis of shoots and roots on explants was also observed. Flower buds and hypocotyls were able to regenerate both organs. Addition of fructose or glucose to the medium stimul ated the organogenesis of shoots, whereas root organogenesis was inhibited on all explants used. Sorbitol strongly inhibited both induction of callus and organogenesis on all explants used.

NADP-isocitrate dehydrogenase (NADP-ICDH) activity of radish (Raphanus sativus L.) seedlings pretreated with various plant growth regulators: KiN, GA, and ABA and different nitrogen sources viz. KNO₃, NH₄Cl and NH₄NO₃ in light and dark was investigated. ICDH activity was significantly higher in light than in dark; addition of different nitrogen sources reduced it to a greater extent in NO₃ supplementation. Among hormonal treatment only KiN showed slight promotion with KNO₃ and NH₄NO₃. On the other hand in light KNO₃ and/or NH₄NO₃ promoted ICDH activity and among hormones, KiN significantly promoted the activity in KNO₃ and NH₄NO₃ supplemented seedlings while ABA was effective in NH₄CL. It is suggested that in non-photosynthetic tissues, NADP-ICDH provides both reductant and carbon skeleton for glutamate synthesis.

Flowering of plants is controlled by hormones among which both stimulators and inhibitors are present. The role of abscisic acid (ABA) in flower induction of the short day plant Pharbitis nil was shown in our experiments through exogenous applications and endogenous level determination of the hormone in cotyledons of seedlings grown under special light conditions. The application of ABA to cotyledons or shoot apices during the first half of a 24-h long inductive night inhibits flowering. The same compound applied towards the end of or after a 14-h long subinductive night increases the number of flower buds produced by these plants. Exposing P. nil seedlings at the beginning of a 24-h long inductive night to far red light (FR) decreases the level of endogenous abscisic acid in cotyledons and leads to flower inhibition. However, a pulse of red light (R) reversing the inhibitory effect of far red light on the flowering of P. nil increases the ABA content. The results obtained confirm previous observations that ABA may play a dual and an important role in the regulation of floral bud formation in P. nil. The flowering occurs when the level of endogenous abscisic acid is low at the beginning and is high toward the end of the inductive night.
