Gene Expression Pattern, Lignin Deposition and Root Cell Wall Modification of Developing Mangrove Propagules Under Salinity Stress
Mangroves have unique adaptations that help them survive in highly saline and hypoxic environments. The present study examines how two mangrove species, namely Kandelia candel (L.)

| description | Mangroves have unique adaptations that help them survive in highly saline and hypoxic environments. The present study examines how two mangrove species, namely
Kandelia candel
(L.) Druce and
Rhizophora mucronata
Lam., well known for their ultrafiltration capability, responded to different salinity levels. We have conducted histochemical, biochemical and gene expression analyses of lignin and cell wall components from the two non-salt-secreting mangrove species treated with different salinity gradients. Root length decreased at higher salinity treatments for
K. candel
(11.7–13.8 cm in freshwater; 5.7–6.7 cm at 20 ppt), while
R. mucronata
(4.9–6.4 cm in freshwater; 5.5–9.4 cm at 35 ppt) showed no significant change. The rate of lignin deposition near the vascular bundles varied from freshwater to salt treatments and between the species. Overall lignin content in the
K. candel
roots increased at higher salinity (40.6–70.6 µg/mg at freshwater to 53.9–145.1 µg/mg at 20 ppt). At the same time,
R. mucronata
showed comparatively higher lignin content (101.4–149.6 µg/mg) than
K. candel
(40.6–145.1 µg/mg)
.
Total pectin concentration increased after 60 days in
K. candel
at freshwater (55.7–199.82 µg/mg) and salt treatments (90.0–210.5 µg/mg at 20 ppt). But pectin content decreased after 60 days of treatment in
R. mucronata
. A similar trend was observed for total carbohydrates and cellulose. Overall, hemicellulose concentration was low in
R. mucronata
compared to
K. candel
. Total polyphenol content was higher in
R. mucronata
(308.1–731.1 µg GAE/mg DW) than in
K. candel
(43.1–400.4 µg GAE/mg DW). Higher gene expression of lignin biosynthesis genes viz
CAD
,
HCT
,
C3H
,
COMT
and peroxidase was observed in
R. mucronata
at 5 ppt salinity 60 days after treatment
.
The results of this study will help explain the role of root lignification in mangrove salinity tolerance mechanisms. |
