Gibberellin (GA) signalling during pumpkin male flower development is highly regulated, including biosynthetic, perception, and transduction pathways. GA 20-oxidases, 3-oxidases, and 2-oxidases catalyse the final part of GA synthesis. Additionally, 7-oxidase initiates this part of the pathway in some cucurbits including Cucurbita maxima L. (pumpkin). Expression patterns for these GA-oxidase-enc...

The KNOTTED1-LIKE HOMEOBOX PROTEIN1 (KD1) gene is highly expressed in flower and leaf abscission zones (AZs), KD1 was reported to regulate tomato pedicel via alteration of the auxin gradient response AZ (FAZ). present work aimed further examine how regulates signaling factors regulatory genes involved abscission, by using silenced lines performing a large-scale transcriptome profiling FAZ befor...

Alstroemeria is one of the most beautiful flowers in the family Alstroemeriaceae. One of the major problems of this cut flower is short life of leaves, this fact reduces the economic value of this cut flower. Abscission of petal before wilting is also considered as one of the most important problems of this flower. Petals of this flower are very sensitive to ethylene. A factorial experiment bas...

The herbaceous vine Mandevilla funiformis (Vell.) K. Schum. occurs in open vegetation the Southern Brazil. present study was carried out a sandbank, east of Florianópolis, Santa Catarina State. Floral morphology, nectar features (production pattern, removal effects, and standing crop), floral visitors (including pollinator, robber thief nectar), fruit set seed germination M. were studied.
