Germline-stem cells (GSCs) produce gametes and are thus true "immortal stem cells".In Drosophila ovaries, GSCs divide asymmetrically to produce daughter Galaxy A51 GSCs and cystoblasts, and the latter differentiate into germline cysts.Here we show that the histone-lysine methyltransferase dSETDB1, located in pericentric heterochromatin, catalyzes H
Development and research of uninterruptible power supply system for networks with supply voltage up to 24 V
Objectives.Due to the continuous rapid development of renewable energy sources, requirements for secondary power supply systems keep increasing from year to year.Productive uptime for end users is dependent on the efficiency and stability of the power supply system.Such systems should be able to distribute and store energy from renewable sources ha
Overexpression of a Phosphate Starvation Response AP2/ERF Gene From Physic Nut in Arabidopsis Alters Root Morphological Traits and Phosphate Starvation-Induced Anthocyanin Accumulation
Physic nut (Jatropha curcas L.) is highly tolerant of barren environments and a significant biofuel plant.To probe mechanisms of its tolerance mechanisms, we have analyzed genome-wide transcriptional profiles of 8-week-old physic nut seedlings subjected to Pi deficiency (P-) for 2 and 16 days, and Pi-sufficient conditions (P+) controls.We identifie
