The surge of interest in fluorescent pseudomonads was spurred by discoveries that members of this group are capable of increasing plant growth and suppressing disease upon introduction into the soil or rhizosphere (Burr et al., 1978; Kloepper and Schroth, 1981; Olsen and Misaghi, 1982, 1984; Weller and Cook, 1983). These bacteria produce iron chelators (siderophores) in vitro with high stabilit...

Although less widespread than Al-toxic acid soils, Mntoxic acid soils do exist in Hawaii (Hue et al., 1998a), Manganese toxicity is a serious constraint to many crops grown Brazil (R.S. Yost, personal communication, 1999), and on acid soils in Hawaii. To develop management strategies to deal with the Mn problem, four experiments were conducted. First, to the Philippines (Hue, 1999). For example...

Background: To better understand effects of iron restriction on Actinobacillus pleuropneumoniae and to identify new potential vaccine targets, we conducted transcript profiling studies using a DNA microarray containing all 2025 ORFs of the genome of A. pleuropneumoniae serotype 5b strain L20. This is the first study involving the use of microarray technology to monitor the transcriptome of A. p...

Symptoms of nutrient deficiency in carambola {Aver rhoa carambola L.), lychee (Litchi chinensis Sonn.) and papaya (Carica papaya L.) trees have been observed periodically in south Florida, but have not been experimentally verified. Young 'Arkin' carambola, 'Mauritius' and 'Brewster' lychee and 'Cariflora' papaya were grown in 26-liter containers filled with coarse silica sand, irrigated with de...

Irradiation of FeDTPA-containing nutrient solutions by a fluorescent plus incandescent light source resulted in the loss of both Fe-chelate and soluble Fe, the formation of a precipitate that was composed mostly of Fe, and a rise in pH. The rate of Fe-chelate photodegradation in solution increased with irradiance intensity and with solution temperature under irradiation, but irradiance had the ...

Economic loss resulting from nickel (Ni) deficiency can occur in horticultural and agronomic crops. This study assesses whether excessive iron (Fe) can induce Ni deficiency. Both chelated Fe and diethylenetriaminepentaacetic acid (DPTA; a commonly used Fe-chelant) induces Ni deficiency in pecan [Carya illinoinensis (Wangenh.) K. Koch]. Foliar sprays of Fe [Fe-DPTA (1.1995 g·L)] during early pos...
