    Traditional breeding and molecular approaches have been used to develop tobacco varieties with reduced nicotine and secondary alkaloid levels. However, low-alkaloid (LA) tobacco varieties often show impaired leaf ripening and senescence leading to poor ...

    Tobacco plants exhibit strong apical dominance that effectively inhibits axillary bud development. However, upon shoot apical meristem removal (topping), loss of apical dominance quickly allows axillary buds to grow (suckers) resulting in yield loss and ...
