Roles of carbohydrate supply and ethylene, polyamines in maize kernel set.

Glucose appears to have an antagonistic relationship with ethylene and ethylene and polyamines appear to play antagonistic roles in the abortion of seeds and fruits. Moreover, ethylene, spermidine, and spermine share a common biosynthetic precursor. The synchronous changes of them and the relationships with kernel set are currently unclear.

Cloning and characterization of a non-TIR-NBS-LRR type disease resistance gene analogue from peach.

Cloning of plant disease resistant genes is greatly helpful for disease resistant breeding in plants and the insight of resistance mechanism. However, there are less relevant researches in peach [prunus persica (L.) Batch].
