objective: castor (ricinuscommunis l.) is an industrial oilseed that belongs to the family euphorbiaceae. castor is believed to be originated in east africa probably ethiopia. although ethiopia is known as a primary diversity for castor the knowledge on nature and extent of variation of the indigenous germplasm is limited. the present test was conducted to study the nature and extent of variabi...

As a plant shoot matures, it transitions through a series of growth phases in which successive aerial organs undergo distinct developmental changes. This process of phase change is known to be influenced by gibberellins (GAs). We report the identification of a putative transcription factor, GLABROUS INFLORESCENCE STEMS (GIS), which regulates aspects of shoot maturation in Arabidopsis thaliana. ...

The Arabidopsis (Arabidopsis thaliana) compact inflorescence (cif) genotype causes altered adult vegetative development and a reduction in elongation of inflorescence internodes resulting in formation of floral clusters. The cif trait requires both a recessive mutation, cif1, and the activity of a naturally occurring dominant allele of an unlinked gene, CIF2. We show here that the pseudovertici...

The cif trait requires both a recessive mutation, cif1, and the activity of a naturally occurring dominant allele of an unlinked gene, CIF2(D). We show here that the pseudovert...

Increasing interest in medicinal plants encourages the growers to consider extending their range of cultivated species. Acclimatization and adaptation species introduced for cultivation new areas remain a challenge modern agriculture. One first steps optimizing technology is determining plant phenology local conditions. Therefore, aim this research was provide standardized scale Agastache sp. a...

Cut dahlia (Dahlia Cav.) flowers have recently become popular, but their marketability has been limited due to poor vase life. The purposes of this study were clarify the roles leaves and inflorescences in senescence cut dahlias discuss sink-source relationship between vegetative organs inflorescences. leaf life was maintained much longer (16.7 days) than inflorescence (7.4 days). not affected ...

In flowering plants, the arrangement of flowers on a stem becomes an inflorescence, and a huge variety of inflorescence architecture occurs in nature. Inflorescence architecture also affects crop yield. In simple inflorescences, flowers form on a main stem; by contrast, in compound inflorescences, flowers form on branched stems and the branching pattern defines the architecture of the infloresc...

In plants, small groups of pluripotent stem cells called axillary meristems are required for the formation of the branches and flowers that eventually establish shoot architecture and drive reproductive success. To ensure the proper formation of new axillary meristems, the specification of boundary regions is required for coordinating their development. We have identified two maize genes, BARRE...
