BREVIPEDICELLUS (BP) encodes a class-I KNOTTED1-like homeobox (KNOX) transcription factor that plays a critical role in conditioning a replication competent state in the apical meristem, and it also governs growth and cellular differentiation in internodes and pedicels.To search for factors that modify BP signaling, we conducted a suppressor screen
Evidence That Thaxtomin C Is a Pathogenicity Determinant of Streptomyces ipomoeae, the Causative Agent of Streptomyces Soil Rot Disease of Sweet Potato
Streptomyces ipomoeae is the causal agent of Streptomyces soil rot of sweet potato, a disease marked by highly necrotic destruction of adventitious roots, including the development of necrotic lesions on the fleshy storage roots.Streptomyces potato scab pathogens produce a phytotoxin (thaxtomin A) that appears to facilitate their entrance into host
Laboratory invesitgations of variability of Ascochyta fabae Speg. isolates obtained from horse bean
Fifty five isolates of Ascochyta fabae Speg.were investigated.They were selected from 1650 isolates of this fungus obtained from horse bean seeds in 1974-1976.All the isolates grew and sporulated on Potato Dextrose Agar, Malt Agar and VITEX COMBO Horse Bean Agar.The rate of their growth amounted to 1-4 mm per 24 hours.The variability of isolates in
The Inside and out of Folate in Strawberries and Avocados
Folate, an important B-group vitamin, is considered a critical vitamin in many countries, with folate deficiency being associated with neural tube defects in newborns.Strawberries and avocados are considered a healthy, tasty snack by many consumers, and may potentially be an important dietary source of natural folates, depending on variety and grow
