Apomixis: A social revolution for agriculture!
ثبت نشده
چکیده
Shaping agriculture for both human needs and for environmental health can be greatly accelerated by properly developing the trait of apomixis. Apomixis is the phenomenon by which certain plants produce ‘seeds without sex’. Introduction of this trait to crop plants would allow the immediate fixing of the genetic make-up of any individual plant that responded particularly well to a given environment or social need by producing seed with identical genetic properties to the parent. This tool would enable us to adapt plants to the environment, rather than the current necessity for adapting the environment to the plants through intensive agricultural practice. In contrast to today’s hybrid technologies, it would make grain and seed once again the same, restoring farmers to their role as innovators. The introduction of this trait into crop plants would herald perhaps the single greatest change in agricultural practice since the dawn of cultivation. To achieve such a revolutionary impact, and to ensure that the impact is both environmentally and socially sound, the trait must be developed to have certain characteristics, and must be accessible to all people. We should develop a concerted, focused and strategic international research programme within the public domain to generate the trait de nova using molecular techniques.

Apomixis is an asexual mode of reproduction through seeds in plant which results in clonal multiplication of the maternal plant due to the absence of meiosis and fertilization of egg cell. It has been reported to occur in >300 plant species belonging to >35 angiosperm families. Apomixis has been common in polyploid grasses, and poorly represented in the crop species. If apomixis could be incorp...
متن کاملApomixis Allows the Transgenerational Fixation of Phenotypes in Hybrid Plants
The introduction of apomixis-asexual reproduction through seeds-into crop plants is considered the holy grail of agriculture, as it would provide a mechanism to maintain agriculturally important phenotypes [1, 2]. Apomicts produce clonal offspring, such that apomixis could be used to transgenerationally fix any genotype, including that of F1 hybrids, which are used in agriculture due to their s...
متن کاملApomixis: a developmental perspective.
The term apomixis encompasses a suite of processes whereby seeds form asexually in plants. In contrast to sexual reproduction, seedlings arising from apomixis retain the genotype of the maternal parent. The transfer of apomixis and its effective utilization in crop plants (where it is largely absent) has major advantages in agriculture. The hallmark components of apomixis include female gamete ...
