Plant Genomes And Genomics Flashcards
Polyploidy
Duplication of genome
Useful in plants eg strawberries and grapes larger size
Also triploids sterile eg. Banana and seedless watermelon easier to eat and digest
Short reads
Illumina
Less error and cheaper
But lots of fragments to put back together
Long reads
Nanopore and Paibio
Less or no fragments so easier to assemble
Amphiploidy
Acts as diploids
So that pairing and recombination can occur
Paleoploidy
Genomic doubling at some point but acting as diploids
RNA polymerases
1&3 structural rnas
2 mRNAs
4 and 5 plant specific involved in chromatin regulation
Cis regulatory elements
Identified by ATAC-sew
Methylation
Methyl added to 5’ of cytosine
Associated with gene transcriptional repression especially if methylation occurs in promoter of gene.
