Words similar to midrib
Example sentences for: midrib
How can you use “midrib” in a sentence? Here are some example sentences to help you improve your vocabulary:
The maize brown midrib mutants have a reduction in lignin content and an altered lignin subunit composition [ 13 ] . Lignin is a complex hydrophobic polymer made of substituted p -hydroxy-cinnamyl alcohol units that differ in their extent of hydroxylation and methoxylation (for recent reviews see [ 14 15 ] ). Lignin is important for the transport of water and plant rigidity and it serves as a defense mechanism against pests and pathogens.
The present study also confirms the role that the maize brown midrib genes play in flowering dynamics.
Maize and sorghum diverged approximately 15-20 million years ago and are considered closely related [ 18 ] . This is reflected by the degree of synteny between maize and sorghum [ 19 ] and the high degree of DNA sequence homology of coding regions between the two species [ 20 ] . In addition, brown midrib mutants exist in sorghum [ 21 ] , making a study on the relationship between cell wall composition of sorghum and flowering directly comparable to the maize study.
The sorghum brown midrib (bmr) mutants, generated via chemical mutagenesis with di-ethyl sulfate (DES), are similar to the bm mutants of maize in that they have brown vascular tissue in the leaves and stem.
While comparisons between a wild type and a mutant that has been subjected to six or seven backcrosses are generally considered acceptable, there is still a small risk of linkage drag, creating the possibility that genes linked to the brown midrib genes are affecting the development.
