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.

This work studied modifications experienced by root mitochondria during whole plant senescence or under light deprivation, using Arabidopsis thaliana plants with YFP tagged to mitochondria. During post-bolting development, root respiratory activity started to decline after aboveground organs (i.e.

Article Synopsis
  • 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.
