Alfalfa (Medicago sativa L.) pho2 mutant plants hyperaccumulate phosphate.

In this article, we describe a set of novel alfalfa (Medicago sativa L.) plants that hyper-accumulate Phosphate ion (Pi) at levels 3- to 6-fold higher than wild-type. This alfalfa germplasm will have practical applications reclaiming Pi from contaminated or enriched soil or be used in conservation buffer strips to protect waterways from Pi run-off.

Seed Rot and Damping-off of Alfalfa in Minnesota Caused by Pythium and Fusarium Species.

Globally, 15 Pythium species have been found to cause damping-off and seed rot of alfalfa, although surveys of species causing disease on alfalfa in the midwestern United States are lacking. Pathogens were isolated by a seedling baiting technique from soil samples of five alfalfa fields in Minnesota with high levels of damping-off. Of the 149 organisms isolated, 93 (62%) were identified as Pythium spp.

Draft Genome Sequence of Pseudomonas syringae pv. syringae ALF3 Isolated from Alfalfa.

We report here the annotated draft genome sequence of Pseudomonas syringae pv. syringae strain ALF3, isolated in Wyoming. A comparison of this genome sequence with those of closely related strains of P.
