SSI |
sporophytic self-incompatibility |
Pollen germination is prevented on stigma surface, if one of the parental alleles are matched by alleles expressed in stigma
|
GSI |
gametophytic self-incompatibility |
All pollen germinates on stigma, but pollen tube growth stops if the allele expressed in haploid pollen is matched by alleles expressed in stigma
|
GSSI |
gametophytic-sporophytic incompatibility |
A combination of sporophytically and gametophytically controlled self-incompatibility
|
HSI |
heteromorphic self-incompatibility |
Incompatibility system that is genetically linked with heterostyly; often a diallelic sporophytic system
|
PSI |
postcygotic self-incompatibility |
Incompatibility reactions act either shortly before fertilization or after fertilization in the development of the zygote, the embryo or the endosperm
|
LA |
lethal alleles |
A large number of lethal alleles leads to near total mortality of self-fertilized embryos
|
U |
unknown mechanism |
Mechanism unknown
|
ID |
inbreeding depression |
After selfing deleterious alleles are expressed and lead to increased mortality during seed development, germination and juvenile growth
|
CSI |
cryptic self-incompatibility |
In selfcompatible species: outcross pollen has faster pollen tube growth and higher probability to sire offspring than self pollen
