1. Germination and fungal infection of wild celery (Apium graveolens L.) seeds, from southern Brazil, under different temperature and disinfection conditions
ABSTRACT Seeds of wild celery (Apium graveolens L.) from southern Brazil were surface disinfected with different solutions of sodium hypochlorite (5 and 10%) and acetic acid (0.5, 1, 2, 4%), and germination success and fungal infection were evaluated after 28 days of incubation at a constant temperature of 30 ºC and 20/30 ºC thermoperiod (12h:12h). Germina

2. Indução termoperiódica da nitrato redutase de membrana plasmática em abacaxizeiro (Ananas comosus) / Thermoperiodic induction of nitrate reductase associated with the plasma membrane in pineapple (Ananas comosus)
A nitrato redutase (NR) atua juntamente com a nitrito redutase (NiR) catalisando a primeira etapa da redução do nitrato. A NR, no citossol, é ativada, principalmente, pela luz e reduz o nitrato a nitrito. Em seguida, este é reduzido a amônio. Trabalhos anteriores demonstraram que a isoforma citossólica da NR está presente nas folhas e raízes do abaca

3. Genetic Regulation of Development in Sorghum bicolor1: III. Asynchrony of Thermoperiods with Photoperiods Promotes Floral Initiation
Asynchronous thermo- and photoperiods were observed to hasten floral differentiation (initiation) in the short day plant Sorghum bicolor (L.) Moench. Shifting the 12 hour thermoperiod forward 0.5 or 2.5 hours hastened floral initiation compared to controls with synchronous thermo-and photoperiods. Delaying the day-night temperature change until 2.5 hours aft

4. Evidence for Non-Circadian Light/Dark-Regulated Expression of Hsp70s in Spinach Leaves1
Expression of six Hsp70s in spinach (Spinacia oleracea cv Longstanding Bloomsdale) leaves grown under isothermal conditions is regulated by a light/dark (L/D) mechanism distinctly different from the light-regulated mechanism for the chlorophyll a/b-binding protein (cab) or small subunit of ribulose-1,5-bisphosphate carboxylase oxygenase (rbcS).
