In the plants, due to mutation in the mitochondrial genome causing cytoplasmic male sterility can be influenced by the nuclear gene (Rf),  which is dominant over the cytoplasmic mitochondrial genome. If a male sterile plant  is pollinated by the fertile male plant with homozygous (Rf)condition, the progeny obtained in F1 will have

#Unit 8. Inheritance Biology
  1. All fertile progeny will be formed
  2. 50% of the progeny will be fertile and 50% progeny will be sterile, but pollinated with the fertile plants
  3. All sterile progeny will be formed but pollinated with the fertile plants
  4. 50% of the progeny will be fertile and 50% progeny will be sterile, but pollinated with the non-fertile plants

At the subcellular level, starch is stored in amyloplasts in the endosperm of cereals. Two enzymes responsible for initiating starch degradation are α- and β-amylase

a) α-Amylase hydrolyzes starch chains internally to produce oligosaccharides consisting of α(1,4)-linked glucose residues

b) β-Amylase degrades these oligosaccharides from the ends to produce maltose, a disaccharide

c) α-Amylase degrades these oligosaccharides from the ends to produce maltose, a disaccharide

d)  α-Amylase hydrolyzes starch chains internally to produce oligosaccharides consisting of  β(1,4)-linked glucose residues

e) β-Amylase also converts maltose to glucose
