Sentence examples for to ovule from inspiring English sources
noun
The structure in a plant that develops into a seed after fertilization; the megasporangium of a seed plant with its enclosing integuments.
Fruit set due to pollen compatibility was sensitive to ovule number per flower and foraging bee density.
Plant resources were shown to be a limiting factor in seed production: when pollen was in abundance, larger plants had a significantly greater seed to ovule ratio than smaller ones.
D class genes are related to ovule identity.
To obtain the success in cross, we have to turn to ovule rescue.
Expression analysis indicated that the WBLH1 gene is not related to ovule development.
Finally, overexpression of full length AtCTF7 with the CaMV 35S promoter leads to ovule abortion, but plant growth is not affected [ 16].
This higher pollen-to-ovule ratio also suggests the cross-pollination nature of these lines (Kulloli et al. 2009).
That is, the pollen tubes that have the most Zea m 1 have first (and thus greater) access to the stylar resources necessary for their growth [28], [37] and, ultimately, for their ability to gain access to ovules.
We propose that the extraordinary abundance (4% of the extractable protein in maize pollen) of this major pollen allergen is the result of selection for a trait that functions primarily in providing differential access to ovules.
To construct the promoter: GUS vectors corresponding to ovule-specific candidate genes, promoter fragments were amplified by PCR using specific primers for each gene and inserted into a pBI101 plasmid after digestion with BamHI and HindIII (At1g27330 and At5g24420), HindIII and SalI (At1g05550), or SalI and BamHI (At5g49180 and At2g47470).
Plant biologists have long speculated about the mechanisms that guide pollen tubes to ovules.
