The phrase "a pair of maize" is not correct in standard English usage.
It is typically used to refer to a quantity of maize, but "pair" is not an appropriate term for counting maize, which is usually measured in units like ears or bushels.
Example: "I bought two ears of maize from the market."
Alternatives: "a couple of ears of maize" or "two pieces of maize."
The results from RBH analysis were the same for both AtNRT3.1 and AtNRT3.2CT, identifying a pair of co-orthologous genes in maize, sorghum and rice and a tandem repeat in Brachypodium (Figure S1).
Group IV included a pair of paralogous genes of rice, maize and poplar, whereas in group VIII a single gene duplication was found only in Arabidopsis and poplar.
The extreme value of 7.21 ± 0.47 separated the sequence pair of maize and rice.
Additionally, maize NCED2 and NCED3 proteins appeared as a pair of paralogs that was related to rice NCED2, whereas maize NCED5 and NCED6 proteins appeared as a pair of paralogs that was related to rice NCED5.
The risk of WCR resistance to TG maize is significant; in a pair of recent greenhouse studies WCR populations reared without a refuge developed resistance rapidly to TG maize hybrids [33], [34].
For example, a pair of coproporphyrinogen III oxidases, CPX1 and CPX2, in maize shows differential targeting ability to chloroplasts and mitochondria (Williams et al. 2006).
Except for a few species-specific genes, most rice and maize CCCH genes had one or a pair of orthologs in switchgrass.
The highest values were recorded for a ferredoxin in the sequence pair Zea mays (maize) and rice (7.21 ± 0.47) and a pair of mannose binding lectins in rice and Hordeum vulgare (barley; 5.93 ± 0.28).
Each rice spikelet contains a single floret, a pair of empty glumes and a pair of rudimentary glumes in contrast to the pair of glumes and two florets present in maize but it is still to be resolved whether empty glumes or rudimentary glumes are analogous to maize glumes [ 5, 13, 29].
