Polycomb group (PcG) proteins are essential gene repressors in higher eukaryotes. However, how PcG proteins mediate transcriptional regulation of specific genes remains unknown. LIKE HETEROCHROMATIN PROTEIN 1 (LHP1), as a component of Polycomb Repression Complexes (PRC), epigenetically mediates several plant developmental processes together with PcG proteins.

In order to address the salinity stress faced by economically important soybean crop, we have transformed soybean cv. PUSA 9712 via direct organogenesis with marker free construct of gene by -mediated genetic transformation.

Henceforth, a competent and reproducible in planta genetic transformation protocol is established for peanut cv. CO7 by standardizing various factors such as pre-culture duration, acetosyringone concentration, duration of co-cultivation, sonication and vacuum infiltration.

The various factors affecting J. curcas in planta transformation were optimized, including decapitation, Agrobacterium strain, pin-pricking, vacuum infiltration duration and vacuum pressure.

The brinjal seeds were infected with Agrobacterium tumefaciens EHA 105 harbouring pCAMBIA 1301-bar plasmid, and the transformants were selected against BASTA®. Several parameters influencing the in planta seed transformation such as pre-culture duration, acetosyringone concentration, surfactants, duration of sonication, vacuum pressure and vacuum duration have been evaluated.
