Anthurium andraeanum is a high-grade potted flower that enjoys global popularity. Its floral organs have been substantially modified, and its ornamental value is based on its petaloid bracts. MADS-box gene products are important transcription factors that control plant development. In particular,
Peace lily (Spathiphyllum wallisii Regel) is a popular ornamental potted plant in Argentina. During May of 2008 (austral autumn), necrotic lesions of unknown etiology were observed on S. wallisii in a nursery in Pontevedra (34°45'6″S, 58°42'42″W). Plants first showed water-soaked areas starting from
Proanthocyanidins (PAs), also known as "condensed tannins", are colorless metabolites produced through the flavonoid pathway that are involved in stress resistance in plants. Because PAs are involved in the anthocyanin biosynthetic pathway, they play a role in the modification of
An 888-bp full-length ascorbate peroxidase (APX) complementary DNA (cDNA) gene was cloned from Anthurium andraeanum, and designated as AnAPX. It contains a 110-bp 5'-noncoding region, a 28-bp 3'-noncoding region, and a 750-bp open reading frame (ORF). This protein is hydrophilic with an aliphatic
CONCLUSIONS
A R2R3-MYB gene AaMYB2 was isolated from Anthurium andraeanum (Hort.) and was functionally characterized to be a positive transcriptional regulator for anthocyanin biosynthesis in the spathes and leaves. Spathe coloration is an important Anthurium andraeanum (Hort.) characteristic, which
Xanthomonas campestris pv. dieffenbachiae is a common pathogen of pot anthurium production in Florida. While X. campestris pv. dieffenbachiae was isolated from systematically infected plants with chlorotic, necrotic, and wilted leaves, a fluidal, beige bacteria was occasionally isolated on nutrient
