We have developed an estrogen receptor-based chemical-inducible system for use in transgenic plants. A chimeric transcription activator, XVE, was assembled by fusion of the DNA-binding domain of the bacterial repressor LexA (X), the acidic transactivating domain of VP16 (V) and the regulatory region of the human estrogen receptor (E; ER).

Results of this investigation of estrogen-inducible green fluorescent protein (GFP) expression patterns using an estrogen receptor fused chimeric transcription activator, XVE, in the monocotyledonous model plant rice might provide helpful indications on estradiol treatment conditions to be used for the XVE system in rice and other monocots.

In a functional screen using a chemical-inducible activation-tagging system, we identified two alleles of Arabidopsis gene PGA6 whose induced overexpression caused high-frequency somatic embryo formation in all tissues and organs tested, without any external plant hormones.

Real-Time Kinematic positioning technique (RTK) is a differential positioning technology that can utilize pseudo-range measurements and carrier phase measurements to provide positioning results with centimeter-level accuracy in real time.

For a general nonlinear non-Gaussian tracking problem, the new concept of conditional posterior Cramer–Rao lower bound (PCRLB) is introduced as a performance metric for adaptive sensor management.…

According to traditional Chinese uranography, the modern constellation Taurus is located within the western quadrant of the sky, which is symbolized as the White Tiger of the West (西方白虎) (Xī Fāng Bái Hǔ). The name of the western constellation in modern Chinese is 金牛座 (jīn niú zuò), meaning "the golden bull constellation".

2022年6月1日 · Ultrathin graphdiyne (GDY) nanosheets confining Cu quantum dots were prepared by a facile one-step strategy. Cu@GDY nanocomposite possesses high-density of active catalytic sites with persistent stability. Cu@GDY based biosensor significantly reduces overpotential and improves sensitivity for organophosphorus pesticides.

2018年5月1日 · Investigation of solid-state fermentation induced by Aspergillus niger, Candida utilis and Bacillus subtilis to obtain high-quality protein feed from drumsticks leaf flour showed that fermentation induced significant changes in the nutritional composition of drumstick leaf flour.

Somatic embryogenesis is a unique pathway for asexual propagation or somatic cloning in plants. The developmental process of somatic embryogenesis shares considerable similarity with that of zygotic embryogenesis, and this is likely due to the conservation in the underpinning cellular and molecular mechanisms between the two processes.
