polymorphisms of DNA at the 50 untranslated regions of ZmDREB2.7 gene were shown to be
essential in controlling the levels of drought tolerance in maize varieties.
Polytrichastrum alpinum is a kind of polar moss that exist in the utmost environment in the
Antarctic. Hence, a stress-responsive transcriptional co activator gene, multi-protein bridging
factor1c (PaMBF1c), was segregated for comparison with Arabidopsis MBF1c (AtMBF1c).
Earlier, the AtMBF1c gene was already recognised as a key regulator for thermo tolerance
reactions and the AtMBF1c gene over expression improved heat tolerance in Arabidopsis.
Transgenic Arabidopsis plants over expressing the PaMBF1c gene when compared with
AtMBF1c over expressing Arabidopsis lines, both lines showed high tolerance to heat stress.
Conclusion
Of late, many researchers detailed the application of the genetic resources from wild crop
progenitors/relatives and extremophiles and authenticated many of them to be better alleles
than alleles from model plants in crop improvement against abiotic stresses. Hence, it would
be required to broaden our efforts to realize the natural genetic variations in the wild
progenitors or accessions which are able to adapt in the extreme environments. To know the
significance of their stress-eluding strategies will allow us to plan and design the breeding and
biotechnological programs to develop crop plants with varied stress tolerance ability. An
important thing to be noted here is that the natural occurring genetic resources might have not
been selected during domestication process due to its deleterious effects on yield. Therefore,
detailed depiction of the “superior” alleles must be executed to avert any compromise of yield
in crop improvement.

French bean is short duration high yielding grain legume crop and it can be used both as pulse
and vegetable. French bean is important source of protein calories in human diet. It has very
high nutritional value containing 20.69 to 25.81% crude protein, 1.72% fats, 72.42%
carbohydrates and 5.83 mg of iron. Among the major constraints, initial heavy infestation of
weeds is one of the important factors, which hinders its overall growth and productivity.
Among the various weed management options herbicide use is not only efficient method but it
