Title Apomixis revisited
 
Creator Kumar, Sushil
 
Subject Apomixis
 
Description The discussions recently published in
Current Science, as reviews on apomixis
in higher plants, by Kaushal et al. and
Bhat et al., are valuable contributions
for generating new ideas in this agriculturally important area. Besides describing
the characteristics of the various forms of
apomixis, the authors1,2 have also attempted to identify techniques that can be used
to observe the occurrence of apomixis,
and features to be present in model systems, as also approaches that should be
employed in these to understand the biology of apomixis in molecular terms.
The authors have reached the conclusion
that, to unravel the enigma of apomixis
(formation of seeds having maternal
genotype without fertilization), detailed
knowledge of the molecular biology of
plant reproductive process is a prerequisite for its apomictic manipulation. They
have advised that new experimentation
on apomixis be directed in Arabidopsis
and rice plants and it be designed to reveal
the regulation of meiosis, endosperm development and parthenogenetic or apomictic embryo development. They have
opined that knowledge-based deregulation of the key regulatory step(s) of the
above-mentioned plant processes might
help engineer apomixis in these systems.
The conclusion is unquestionable.
