Oligohistidine‐Functionalized Single‐Walled Carbon Nanotube‐Guided RNA Delivery to Improve Shoot Regeneration Efficiency in Plant Calli

open access: yesAdvanced Functional Materials, EarlyView.
The pH‐sensitive His6‐SWNTs, which is functionalized with oligohistidine, can deliver STTM396 molecules into callus cells. The STTM396–SWNT complex treatments enhance shoot regeneration efficiency by regulating the miR396‐GRF module in Arabidopsis and tomato calli.

Chloroplast-specific universal primers and their uses in plant studies

open access: yesBiologia Plantarum, 2011
Universal (consensus) primers are those primers that have the ability to amplify the targeted region of DNA across a broad range of individuals in a certain group of organisms. In plants, such universal primers have been designed to target regions in the

PHR‐Mediated Pi Starvation Response Mobile Messenger RNAs Represent Noncoding Transcripts in Recipient Tissues

open access: yesAdvanced Science, EarlyView.
Mobile messenger RNAs (mRNAs) can travel long distances, serving as systemic signals that participate in plant growth and stress acclimation. This work determines that PHR proteins mediate the Pi starvation response (PSR)‐specific long‐distance transport of mRNAs and that these PSR‐specific mobile mRNAs represent noncoding transcripts in recipient ...

Chloroplast Fibrillin‐Mediated α‐Tocopherol Biosynthesis Impaired by a Virus to Enhance Infection and to Improve Drought Tolerance

open access: yesAdvanced Science, EarlyView.
ToCV‐encoded p22 targets chloroplast plastoglobules (PGs) via directly binding PG structural protein FBN1.1, reducing the size of PG and inhibiting α‐tocopherol biosynthesis via competing with tocopherol cyclase (VTE1). Consequently, the elevated chloroplast ROS not only creates a suitable cellular environment for efficient ToCV infection but also ...
