Versatile CRISPR‐Cas Tools for Gene Regulation in Zebrafish via an Enhanced Q Binary System

open access: yesAdvanced Science, EarlyView.
This study introduces CRISPR‐Q, a transgenic CRISPR‐Cas system leveraging the QFvpr/QUAS binary expression platform in zebrafish. CRISPR‐Q overcomes previous challenges in achieving stable and efficient gene regulation. By enabling precise spatiotemporal control of transcript knockdown (CRISPR‐QKD) and gene activation (CRISPR‐Qa), it provides a ...

The Relationship of Yolk Pigmentation to Candled Grade

open access: yesPoultry Science, 1973
Abstract Hens previously depleted of pigment were fed a white corn basal diet containing 11, 22, 44 and 66 mg./kg. of feed of either beta-apo-8′-carotenal (a yellow pigment) or canthaxanthin (a red pigment). Additional birds were maintained on the basal without added pigments. Seven collections of eggs were made at seven-day intervals beginning after
