Tomato Shade Avoidance: Unraveling Internode Elongation and Hormonal Harmony

This study provides a comparison of gene expression in two tomato cultivars, Moneymaker and M82, focusing on first internode and its innermost cell type pith—under two light conditions: white light with far-red supplementation (WL+FR) and the control condition of white light (WL). The samples were harvested at four time points leading to the point where internode elongation could be measured in response to WL+FR. The timepoints were 6, 24, 30, and 48 hours after treatment initiation. Overall design: The experimental setup was coded for efficient tracking and comparison: "M" was used to denote Moneymaker and "2" for M82 as the initial digit of the sample code. "F" indicated far-red light treatment (FR), and "W" designated white light (WL). The third digit was reserved for the replicate number, representing the plants grown in the same batch. The fourth and final digit identified the sample sequence, with "1" corresponding to the internode sampled at 6h, "2" for the internode at 24h, "3" for the internode at 30h, and "4" for the internode at 48h. Similarly, "5" represented pith samples at 30h, and "6" for pith at 48h. This coding system streamlined the process of data collection and analysis, allowing for a clear distinction between the variables being studied.
