AI Article Synopsis
Article Abstract
L. is an important medicinal plant, commonly known as the toothache plant. It is a rich source of secondary metabolites used for the treatment of different human disorders. The demand for L. has increased due to its putative health benefits (in terms of both biomass quantity and bioactive compound purification). In vitro plant cultures have allowed the rapid increase of raw material availability through the use of suitable regeneration and multiplication systems. On the other hand, there is a general lack of methods for genetic transformation as a promising new technological approach for the improvement of secondary metabolites. In this work, an efficient transformation protocol has been established using the LBA4404 strain bearing the binary vector pBI121 containing the gene for the resistance to kanamycin. Plant genetic transformation has been verified by direct polymerase chain reaction and GUS assay on regenerants. Transformation efficiency has been affected by the high level of the selection agent kanamycin. To our knowledge, this is the first report on the genetic transformation of paving the way to further studies to improve in vitro plant growth and secondary metabolite production.

De novo synthesis of phage genomes enables flexible genome modification and simplification. This study explores the synthetic genome assembly of phage vB_PaeS_SCUT-S4 (S4), a 42,932 bp headful packaging phage, which encapsidates a terminally redundant, double-stranded DNA genome exceeding unit length. We demonstrate that using the yeast TAR approach, the S4 genome can be assembled and rebooted from a unit-length genome plus a minimal 60 bp terminal redundant sequence.

The increasing challenges posed by plant viral diseases demand innovative and sustainable management strategies to minimize agricultural losses. Exogenous double-stranded RNA (dsRNA)-mediated RNA interference (RNAi) represents a transformative approach to combat plant viral pathogens without the need for genetic transformation. This review explores the mechanisms underlying dsRNA-induced RNAi, highlighting its ability to silence specific viral genes through small interfering RNAs (siRNAs).

Horizontal gene transfer (HGT) plays a pivotal role in bacterial evolution, shaping the genetic diversity of bacterial populations. It can occur through mechanisms such as conjugation, transduction, and natural transformation. , a model Gram-positive bacterium, serves not only as a robust system for studying HGT but also as a versatile organism with established industrial applications, such as producing industrial enzymes, antibiotics, and essential metabolites.

Light is an important environmental factor affecting the ripening and quality of strawberry fruit. Previous studies have shown that red light treatment can promote strawberry ripening. Gene expression is closely associated with chromatin openness, and changes in chromatin accessibility are crucial for the binding of transcription factors to downstream regulatory sequences.
