K. Veluthambi is a plant researcher whose work with B. W. Poovaiah investigated hormonal control of polypeptide patterns during strawberry development. Their 1984 study combined manipulation of auxin supply with SDS-PAGE measurements, connecting whole-fruit growth to changes in molecular composition.[ref]
Auxin-regulated polypeptide changes at different stages of strawberry fruit development by K. Veluthambi and B. W. Poovaiah. Byline, affiliation and Abstract: developmental polypeptide patterns
For example, an approximately polypeptide appeared between five and ten days after pollination in the controls. Removing the achenes prevented its appearance; treatment with the synthetic auxin naphthaleneacetic acid restored it. Other bands changed at later developmental stages, showing why the timing of collection matters.[ref]

An illuminating comparison is between two samples collected on the same day, one deprived of auxin and one supplied with it. Comparing samples of different ages instead would mix treatment effects with ordinary development. This makes the study an example of pairing a physiological intervention with a molecular measurement, while leaving the identities and causal roles of individual proteins as further questions.
