Which of the following govern sporophytic self-incompatibility in Brassica?
SI in Brassica vegetables belongs to SSI and is sporophytically controlled by the S-locus. Three tightly linked genes are distributed on the S-locus, including SRK (S-locus receptor kinase), SLG (S-locus glycoprotein), and SCR (S-locus cysteine-rich protein)/SP11 (S-locus protein 11).

See lessWhich of the following transfers a set of genes encoded in a region called T-DNA of the Ti-plasmid into cells at wound positions?
The transfer DNA (abbreviated T-DNA) is the transferred DNA of the tumor-inducing (Ti) plasmid of some species of bacteria such as Agrobacterium tumefaciens and Agrobacterium rhizogenes (actually an Ri plasmid). The T-DNA is transferred from bacterium into the host plant's nuclear DNA genome.

See lessWhich of the following technique can be used to develop nematode resistant plants?
The process involved in the production of nematode-resistant plants is RNA interference or RNAi. Using Agrobacterium vectors nematode-specific genes were introduced into the host plant. The introduction of DNA was such that it produced both sense and antisense RNA in the host cells.

See lessWhich of the following have been used for cryo-preservation of germplasm with 90% tissue survival and 10%plant regeneration that are used in international exchange of germplasm?
A cryoprotectant is a substance used to protect biological tissue from freezing damage (i.e. that due to ice formation). Arctic and Antarctic insects, fish and amphibians create cryoprotectants (antifreeze compounds and antifreeze proteins) in their bodies to minimize freezing damage during cold winRead more

An organism's phenotype can sometimes be determined based on the parent's genotype using a Punnett square. An organism's phenotypic expression refers to the observable characteristics in an organism that results from the expression of genes.

The avermectins are derived from a family of macrocyclic lactones produced by the soil microorganism Streptomyces avermitilis. Abamectin (avermectin B1) was introduced in 1985 as a crop insecticide against mites and some insect species.
