This work focuses on the alterations in soybean root growth and activity during whole plant senescence and the contribution of roots to source-sink relations during plant development. The experiments were designed to analyze the activity of roots in relation to: a) whole plant senescence, b) total pod removal and c) root pruning (15, 25 and 50% of DW) during seed growth stages. Roots can grow until an advanced R5 stage and their specific activity decreases along the reproductive development but whole root activity declines from R6.

During post-bolting development, root respiratory activity started to decline after aboveground organs (i.e.

- The study examines how plant hormones brassinosteroids (BRs) and ethylene (ET) affect ascorbic acid-glutathione levels in tomato plants, revealing their interaction in regulating antioxidant metabolism.
- BR-deficient mutant leaves have low total ascorbic acid (AA), while BR-accumulating leaves maintain normal AA levels, indicating that both BR and ET pathways influence AA synthesis.
- Suppressing ET in BR-deficient and BR-accumulating plants restores normal AA content and enzyme activity, suggesting that while ET inhibits AA synthesis, BRs promote it.
