Physiological and transcriptional reprogramming for salinity tolerance of endangered mangrove associate Hernandia nymphaeifolia.

ABSTRACT:

Background

Hernandia nymphaeifolia is a typical mangrove associate with high ecological, ornamental, and medicinal values, but in China, it has become endangered in recent years, and an urgent protection is needed. Salinity is a key factor for growth and survival of mangrove seedlings, and thus a comprehensive understanding of salt tolerance in mangroves is important for their conservation and afforestation. However, little is known regarding salt-responsive mechanisms in H. nymphaeifolia.

Results

In this study, we posed gradient salt treatments on H. nymphaeifolia seedlings and investigated their physiological and transcriptional reprogramming in response to salinity stress. The results revealed that hyper-salinity stress adversely impacted on leaf growth, cell integrity an
