I feel it is very confusing when I see sentences such as this one in papers published in prestigious scientific journals (written by native speakers):
35S:ZPR2-GFP plants often showed termination of meristem activity and the formation of a pin-like structure.
Someone please tell me why there is no 'the' before 'termination' while there is a 'the' before 'formation'?
Here are two more similar sentences that I noticed in another paper:
- Formation of mature GCs in rice requires the stomatal maturation bHLH OsFAMA.
- Here, we identify a locus responsible for the formation of SCs in Brachypodium.
I really don't know why the definite article 'the' only appears in the second sentence (before 'formation') but not in the first one (at the beginning).
