Time-Course Transcriptome Analysis of Compatible and Incompatible Pollen-Stigma Interactions in Brassica napus L.
Brassica species exhibit both compatible and incompatible pollen-stigma interactions, however, the underlying molecular mechanisms remain largely unknown. Here, RNA-seq technology was applied in a comprehensive time-course experiment (2, 5, 10, 20, and 30 min) to explore gene expression during compatible/incompatible pollen-stigma interactions in stigma. Moderate changes of gene expression were...
متن کاملSequence variability and developmental expression of S-alleles in self-incompatible and pseudo-self-compatible petunia.
We investigated the structure and expression of three S-alleles of Petunia hybrida in self-incompatible varieties and in a pseudo-self-compatible line in which the self-incompatibility response is defective. Comparison of derived amino acid sequences from different gametophytic S-alleles revealed a pattern of sequence conservation and variability that was highly nonrandom. In self-incompatible ...
متن کاملAn S Receptor Kinase Gene in Self-Compatible Brassica napus Has a l-bp Deletion
S locus glycoprotein (SLG) and S locus receptor kinase (SRK) cDNAs were isolated from an S allele present in a number of self-compatible Brassica napus lines. This Aí0 allele did not segregate with self-incompatibility in crosses involving other self-incompatible B. napus lines. The SLG-Aí0 cDNA was found to contain an intact open reading frame and was predicted to encode an SLG protein with se...
متن کاملThe pollen determinant of self-incompatibility in Brassica campestris.
Many flowering plants possess self-incompatibility (SI) systems that prevent inbreeding. In Brassica, SI is controlled by a single polymorphic locus, the S locus. Two highly polymorphic S locus genes, SLG (S locus glycoprotein) and SRK (S receptor kinase), have been identified, both of which are expressed predominantly in the stigmatic papillar cell. We have shown recently that SRK is the deter...
متن کاملInbred Relatives with Special Reference to Selfing
The covariance of inbred relatives from a population in linkage and identity equilibrium in the presence of dominance and epistasis is formulated using a similar procedure to that which B. S. WEIR and C. C. COCKERHAM used to derive a general expression for the genotypic variance. An alternative model based on the description of a genotype in terms of the homozygotes of its constituent alleles i...
