A pectin acetyl‐transferase facilitates secondary plasmodesmata formation and RNA silencing movement between plant cells

The Plant Journal, Volume 122, Issue 3, May 2025.
SUMMARY Some silencing small (s)RNAs, comprising micro (mi)RNAs and small‐interfering (si)RNAs, move between plant cells to orchestrate gene expression and defense. Besides possible redundancy or embryo lethality, a prevalent challenge in genetic studies of mobile silencing is to discriminate bona fide alterations to sRNA movement from impaired cell ...

PAPR reduction using polynomial based compressing with Rapp model in GFDM

e-Prime: Advances in Electrical Engineering, Electronics and Energy
Generalized Frequency Division Multiplexing (GFDM) has been considered as an attractive candidate to replace Orthogonal Frequency Division Multiplexing (OFDM) for the fifth generation (5 G) mobile networks. GFDM system has better spectral characteristics
