Shoot and inflorescence branching.
A major aspect of postembryonic plant development is the formation of secondary axes of growth: vegetative branches, inflorescence branches, or flowers. The first step in side-shoot development is the establishment of lateral meristems in the axils of leaves. GRAS-, MYB-, and bHLH-type transcription factors act as key regulators of early steps in this process. The REVOLUTA subfamily of HD-ZIP t...
متن کاملModelization of the spatial distribution of corn head smut (Sporisorium reilianum Langdon and Fullerton) in Mexico
Sporisorium reilianum has caused significant economical damages in Mexico, in temperate and relatively dry areas, where maize is cultivated. The knowledge about the spatial distribution of this pathogen is basic to elaborate integrated management programs, and precise and eff icient the development of sampling methods and control techniques. Unfortunately, in Mexico there are no studies on spat...
متن کاملImplication of Gibberellins in Head Smut (Sporisorium reilianum) of Sorghum bicolor.
The head smut fungus, Sporisorium reilianum ([Kuhn] Landon and Fullerton), was shown to reduce plant height in infected Sorghum bicolor ([L.] Moench) plants. The major reductions occurred in the internodes nearest the panicle and were more severe in naturally infected than in inoculated plants. Less affected plants developed reproductively sterile panicles, and eventually smutted panicles devel...
متن کاملMating type loci of Sporisorium reilianum: novel pattern with three a and multiple b specificities.
Sporisorium reilianum and Ustilago maydis are two closely related smut fungi, which both infect maize but differ fundamentally in their mode of plant invasion and site of symptom development. As a prelude to studying the molecular basis of these differences, we have characterized the mating type loci of S. reilianum. S. reilianum has two unlinked mating type loci, a and b. Genes in both loci an...
متن کاملPositively Selected Effector Genes and Their Contribution to Virulence in the Smut Fungus Sporisorium reilianum
Plants and fungi display a broad range of interactions in natural and agricultural ecosystems ranging from symbiosis to parasitism. These ecological interactions result in coevolution between genes belonging to different partners. A well-understood example is secreted fungal effector proteins and their host targets, which play an important role in pathogenic interactions. Biotrophic smut fungi ...
