We have identified seed coats of several citrus varieties as having high levels of 'Ca. Liberibacter asiaticus' DNA and in immature seeds and use microscopy to demonstrate viability of bacteria. We will determine if there are optimal stages of development of the seed for extraction of bacteria by sampling populations of seeds collected from fruit at various stages of development. We will test various mechanical methods to purify intact cells from the seed coats.
