Q893
Genes for Male sterility in plants are mainly located in
A.
Mitochondrial genome
AnswerB.
Cytosol
C.
Neuclear genome
D.
Plastid genome
Answer: Option A
Solution
Answer: Option A
Solution:
Genes for Male sterility in plants are mainly located in the Mitochondrial genome.In plants, male sterility can be caused either by mitochondrial genes with coupled nuclear genes or by nuclear genes alone; the resulting conditions are known as cytoplasmic male sterility (CMS) and genic male sterility (GMS), respectively.
Plants possess mitochondrial genomes that are large and complex compared to animals. Plant mitochondrial genomes range between 200 - 2,000 kbp.
