"ranked 2nd" is correct and usable in written English.
You can use it when referring to the position, order, or ranking of someone or something. For example: "The team ranked 2nd in the tournament."
Genes that persistently responded to starvation during recovery include MTPA1 (encoding a zinc transporter, responding at 10.2 fold) ranked 2nd, At3g53770 (encoding a LEA3 family member, responding negatively at 3.8 fold) ranked 6th, and MYB72 (encoding a TF mediating systemic resistance, responding negatively at 7.3 fold) ranked 8th.
For example, "Root Cells," which is a compendium of expression profiles from cell types [ 28, 29], ranked 2nd for all attributes.
For example, TFs participating in cell cycle checkpoint [ 9], S w i4 p, S w i6 p, and M b p1 p, ranked 2nd and, interestingly, the 3-clique including D i g1 p, M c m1 p, and S t e12 p (the pheromone responding TF module) ranked 4th.
The most highly expressed genes in the zygote (with 6 or more probes) included the heat shock 70 protein, PF08_0054 (ranked 1st); the P. falciparum gamete antigen, PF13_0011 (ranked 2nd); a sexual stage specific protein, PFD0310w (ranked 24th); and circumsporozoite-trap related protein (CTRP), PFC0640w (ranked 20th).
