| Summary: | Several approaches have been proposed, in the past, for the development of
hybrid wheat varieties. Nevertheless, common wheat hybrids today account for
less than 1% of the world's wheat production. The reason for the limited
success of hybrid wheat varieties is the fact that to date, a simple and
efficient system for the production of hybrid seed has not been developed. A
two-line system using photoperiod-sensitive cytoplasmic male sterility
(PCMS) caused by Aegilops crassa Boiss. cytoplasm seems to be very promising
way to produce hybrid wheat seed on large scale. Non-desirable side effects
of PCMS system are the unreliable sterility of the male sterile lines under
different latitudes. Therefore, we tried to connect male sterility system
based on Ae. crassa cytoplasm with chemical induction of male sterility. The
presented results reveal that the majority of male sterility genes are
conserved in the Ae. crassa cytoplasm and that their effects can be promoted
by chemical signals, such as synthetic auxins (e.g.,
2,4-Dichlorophenoxyacetic acid). Our research work represents the
development of a novel male sterility system which is controlled by chemical
signals (e.g., synthetic auxins and their pro-herbicide analogues) and
mediated by Ae. crassa cytoplasm. |
