Genomic DNA was isolated using SP Plant Mini Kit (Omega) and REDExtract-N-AMP Plant PCR Kit (Sigma) was used for the segregation analysis.
From the pellet the pneumococcal DNA was extracted using the Extract-N-Amp Plant PCR Kit (Sigma-Aldrich, St . Louis MO, USA).
Students began the molecular biology portion of the module by extracting DNA from the leaves of each of their plants as described in the REDExtract-n-Amp Plant PCR Kit (Sigma-Aldrich, St . Louis MO).
De novo designed AMPs for plant protection.
To date, in spite of the increasing number of reported AMPs from plants, developments in gene expression methodologies and computational algorithms lead to new prospective strategies of biomining AMPs in plant systems.
Recent studies repeatedly report peptide instabilities [ 3], which has become the main focus for the de-novo design of AMPs for plant protection [ 11, 12].
This approach could be considered feasible for expressing synthetic AMPs in plants either to establish disease resistant plants or to facilitate molecular farming.
The stable ectopic expression of AMPs in plants allows for the use of plants as biofactories or in the protection of crops against a wide range of pathogens [ 3, 4].
Plant defensins are a class of plant AMPs with structural and functional properties that resemble the defense peptides produced by fungi, invertebrates, and vertebrates, called "defensins".
These molecules constitute a family of plant AMPs, members of which contain six conserved cysteines that stabilize the structure by the formation of disulfide bonds [ 74].
Defensins are among the best-characterized cysteine-rich AMPs in plants [ 27, 65].
