Study of shade adaptive traits of understorey crops is of
utmost importance for their potential use in agroforestry
system. The present study was conducted to decipher
shade-adaptive traits through comparative changes in leaf
pigments, epicuticular wax level and protein profiles in
leaves of green gram and soybean grown in three different
regimes of shade (33%, 50%, and 75% shade) and without
shade (open sunlight). Chlorophyll a (Chl a), Chl b and
total Chl progressively increased, whereas, Chl a/b ratio
gradually decreased with increase in shade intensity in
both the crops. Anthocyanin, wax level and soluble protein
of leaves gradually decreased with increase in shade.
Green gram showed higher anthocyanin than soybean in
all the light environments. Wax level of leaf in green gram
was higher in open than soybean, whereas, it was
comparable in 33% shade in both the crops. Wax level of
leaf in green gram decreased more in deep shade (50%
shade and 75% shade) than soybean indicating more
shade resilience of soybean. The rate of shade-induced
reduction of leaf protein content in soybean was less than
green gram. Protein profiling through SDS-PAGE clearly
revealed degeneration of proteins in shade around ~55
kDa which indicated to the RUBISCO (Ribulose
bisphosphate carboxylase-oxygenase) proteins. Both the
crops revealed their shade adaptation mainly through
alteration in epicuticular wax, pigments and proteins mostly
associated with LHCP (Light harvesting complex protein)
complex and towards RUBISCO protein which assume
significance for their use in crop improvement programme
in searching shade tolerant crops for agroforestry system.
