The restoration of fertility of F1 hybrid is prerequisite, especially when the economic product is seed. Proc Natl Acad Sci U.

It includes two tapetum-specific expression cassettes; one expressed in the female parent and the other expressed in the male parent of the desired F1 progeny. Theoretical and Applied Genetics— Defective in Tapetal development and function 1 is essential for anther development and tapetal function for microspore maturation in Arabidopsis.

The mutation retained dimerization and functional activity of the COP1 but barnxse its nuclear abundance. Journal of Molecular Biology.

Barnase Barstar Gene of Male Sterility |authorSTREAM

Surendra Pratap Singh1 Sudhir P. Pollen germination images were taken on Leica microscope. If all goes well, will this be the first GM food crop that Indian farmers will plant?

In this study, we included the light-regulated transcription factor HFR1 that exhibits its COP1-mediated degradation 374950 to limit TBPm3 and abolish expression of the desired gene. The limited cellular availability of TBPm3 protein leads to the abolition of expression of the transgene in tapetum cells Fig.

Barnase – Wikipedia

Here, we report a male sterility—fertility restoration system by engineering the inmost nutritive anther wall layer tapetum of female and male parents. The pKA values of the denatured state are on average 0. Manu Agarwal, Delhi University, India for critical reading and the important suggestions in their article. In the male parent, tapetum—specific Constitutive photo-morphogenesis1 COP1 was expressed. Plant Biotechnol J 8— In addition, the male sterile female lines are equipped with additional regulatory control over the TGTA-TBPm3 system operated through the male component.

A novel male sterility-fertility restoration system in plants for hybrid seed production

Plant Biotechnol J 133—42 All results are an average of 10 independent lines with three independent experiments of T1 lines. UBIQ10 was taken an internal control. Brstar would then be reviewed by barsfar the sysyem and the GEAC, before a final decision is taken.

The proposed male sterility-fertility restoration system described here will be a valuable future contribution for exploiting hybrid vigor and commercial production of hybrid seed.

S6f-g ; whereas in case of pollens of transgenics, the cytoplasm collapsed and severe deformity was observed in the pollen wall Fig. Samples were washed thrice, with 0.
