Based on Table 1, which statement accurately compares Laccaria bicolor with the four nonmycorrhizal fungal species regarding gene numbers?
A: L. bicolor has significantly more protein-coding genes than all other listed species.
B: L. bicolor consistently has the highest number of genes for membrane transporters among all listed species.
C: L. bicolor possesses a remarkably higher number of genes for small secreted proteins (SSPs) compared to any of the nonmycorrhizal species.
D: The number of genes for membrane transporters is inversely proportional to the number of SSP genes across all species.
Explanation
Table 1 shows that L. bicolor has 2,191 genes for small secreted proteins SSPs , while the nonmycorrhizal species have 838, 163, 313, and 58 respectively. This represents a significantly higher number in L. bicolor, suggesting their specialized role in mycorrhizal interactions.
