Isoforms Cooperatively Regulate Temperature-Related Flowering in .

Timely flowering is a determinative trait for many economically valuable species in the genus of the Orchidaceae family, some of which are used for ornamental and medicinal purposes. , a representative species of nobile-type , normally flowers in spring after exposure to sufficient low temperatures in winter. However, flowering can be stopped or disrupted by the untimely application of high temperatures.

A Stable -Mediated Transformation of Cotton ( L.) and Plant Regeneration From Transformed Hairy Root via Embryogenesis.

Genetic transformation is a powerful tool to study gene function, secondary metabolism pathways, and molecular breeding in crops. Cotton ( L.) is one of the most important economic crops in the world.

Multidrug resistance in breast cancer cells during epithelial-mesenchymal transition is modulated by breast cancer resistant protein.

Background And Objective: Epithelial-mesenchymal transition (EMT) not only initiates invasion and metastasis of tumors, but also induces multidrug resistance in tumor cells. Our experiment analyzed the dependability between breast cancer resistant protein (BCRP) and EMT in breast cancer to explore the effect of EMT on BCRP-mediated multidrug resistance.

Methods: The expressions of BCRP and transcription inhibitor Snai1 (Snail) in breast cancer were detected by immunohistochemistry.

Construction and analysis of cotton (Gossypium arboreum L.) drought-related cDNA library.

Background: Drought is one of the most important environmental factors causing water stress for cotton, and it greatly limits cotton growth and crop productivity. So far only a few drought-tolerance genes have been functionally characterized in details, and most efforts on this topic have been made in model organisms. Therefore, to identify more drought-related genes in cotton plays a crucial role in elucidating the underlying mechanisms of drought tolerance as well as utilizing bioengineering techniques to improve the tolerance in this organism.

Histological and ultrastructural observation reveals significant cellular differences between Agrobacterium transformed embryogenic and non-embryogenic calli of cotton.

Over the past few decades genetic engineering has been applied to improve cotton breeding. Agrobacterium medicated transformation is nowadays widely used as an efficient approach to introduce exogenous genes into cotton for genetically modified organisms. However, it still needs to be improved for better transformation efficiency and higher embryogenic callus induction ratios.
