Abstract

Faba bean is an important legume crop; it is the principal protein source
for poor people in some Asian and African countries. Salinity stress is one of
the main abiotic stresses that limits plant growth, crop productivity and yield
quality. Present study aimed to investigate different responses of two Faba
bean varieties (Sakha-3 and Giza-716) to two used levels of NaCl (50 and
100 mM) and exogenous application of Folic acid (FA), Royal jelly (RJ) and
5-azacitidine (5-AZA) as well as their combinations treatments. The present
investigation aimed also to determine germination %, shoot and root lengths,
fresh and dry weights, photosynthesis pigments, rate of electrolyte leakage
(EL), Lipid peroxidation product (MDA), changes in separating pattern of
total soluble protein, mitotic index, chromosomal aberrations were also
studied. On the other hand changes in the expression levels of some
antioxidant enzymes encoding genes (SOD, CAT and GR) as well as some
protection and growth related proteins (HSP-17.9 and GPRP) and two DNA
methyltransferases encoding genes (MT1 and MT2) were also evaluated using
quantitative real time PCR. The obtained results showed that, salinity stress
induced a reduction in most of studied parameters such as root and shoot
lengths, fresh and dry weights, germination % and mitotic index.
