1 Small Tree - High Productivity Initiative Molecular achievements
11th Annual Mango Conference May 2nd - 5th 2017

2 Objectives of Molecular Team
Improve the genetic resources for small trees Identifying the genes involved Monitoring gene expression on collected samples Correlating phenology with physiological switches Here you should briefly describe the objective of the Molecular team. Correlating phenology with physiological variations. With a special emphasis about Floral regulation, shoot branching and juvenilty Here describe the procedure and emphasis on the fact that the genetic resources were very poor for these species. You can mention the different type of tissue we collected (stem, leaves (mature and immature), axillary buds, termial buds, flowers) To understand the genetic and physiological regulation of: Floral initiation Shoot architecture Juvenility

3 Objectives of Molecular Team
Amount of Development Jan Feb Mar Apr May Jun Jul Aug Oct Sep Nov Dec Harvest Fruit Development Flowering and fruit set Flower Bud Development Vegetative Dormancy Period Root Flush Vegetative Flushing Mango Phenology Cycle Here you should briefly describe the objective of the Molecular team. Correlating phenology with physiological variations. With a special emphasis about Floral regulation, shoot branching and juvenilty

4 DNA or RNA? DNA RNA Protein

5 How? RNA Pool Sequence Stem (elongating or well developed)
Terminal bud (dormant, swelling or active) Axillary bud (dormant, swelling or active) Leaf (young or mature, at light or shaded) Flower (at different stages) Fruit RNA Pool Sequence 12 months
