The list of ncRNA effects includes gene silencing, position effect, hybrid dysgenesis, chromosome dosage compensation, imprinting, allelic exclusion, transvection, transduction, paramutation
, and altered chromatin modifying complexes.
is the process that produces multicolored corn kernels, for instance.
This year's volume contains 28 reviews on such topics as the control of mitotic spindle length, trans-membrane signaling proteoglycans, a new wave of cellular imaging, rolling cell adhesion, chromatin regulatory mechanism in pluripotency, paramutation
and development, regulatory mechanisms for specification and patterning of plant vascular tissues, stem cell models of cardiac development and disease, and a decade of systems biology.
The best known examples of epigenetics are paramutation and parental imprinting.
Walker EL, Panavas T (2001) Strucrural features and methylation patterns associated with paramutation and the rl locus of Zea mays.
So, lpa241 (and probably the other lpa-1 type mutations so far isolated) might be the first case of paramutation having no connections with that pathway.
Paramutation alters regulatory control of the maize pl locus.
gene silencing, paramutation
, genomic imprinting, position effect, etc.
These mutation and mutation-like events include single allele changes, intragenic recombination, unequal crossing over, element transpositions, DNA methylation, paramutation, and gene amplification.
Coe (1966) later described paramutation at the B locus, also controlling seed and plant color.
