Description
Alfalfa KK179 was developed to have reduced levels of guaiacyl lignin (G), a major subunit component of total lignin, compared to conventional alfalfa at the same stage of growth.
This reduction in G lignin leads to reduced accumulation of total lignin in alfalfa through the suppression of caffeoyl CoA 3-O-methyltransferase (CCOMT), a key enzyme in the lignin biosynthetic pathway.
Recipient Organism or Parental Organisms
The term Recipient organism refers to an organism (either already modified or non-modified) that was subjected to genetic modification, whereas Parental organisms refers to those that were involved in cross breeding or cell fusion.

Further details
Notes regarding the genetic elements introduced or modified in this LMO
The transformation cassette in KK179 consists of inverted repeat DNA segments of the CCOMT gene derived from alfalfa. The inverted repeat sequence produces double-stranded RNA (dsRNA) which suppresses endogenous CCOMT gene expression via the RNA interference (RNAi) pathway. Suppression of the CCOMT gene expression leads to lower CCOMT protein expression resulting in reduced synthesis of G lignin subunit.
The PV-MSPQ12633 vector contained two transformation cassettes. the first consisting of the CCOMT inverted repeat sequence and the other containing the nptII coding sequence.
Southern blot analysis showed that only a single copy of the CCOMT transformation cassette was transformed into the alfalfa genome. No plasmid vector backbone sequences are present in KK179 and no DNA sequences from the nptII transformation cassette were detected.
