17 Enzyme cleaves cell walls to make cells divide and expand The effect of expansin14-day after treatment
18 Morphogenesis depends on pattern formation Morphogenesis organizes dividing and expanding cells into multicellular arrangements such as tissues and organs.
19 Development is the sum of all the changes (patterned differentiated cells, tissues, organs) that progressively elaborate an organism’s body.Growth PatternsDifferentiationDifferentiatedvesselDifferentiatingvesselmeristem
29 Classified by Developmental Stages Types of Growth-Classified by Developmental StagesPrimary growth:Apical meristems extend roots and shoots by giving rise to the primary plant bodySecondary growth:Lateral meristems add girth by producing secondary vascular tissue and periderm
40 We still can study some plants lack of advantages like Arabidopsis- A Bamboo examplesImportant of vegetable inTaiwan Bamboo do not easily flower (juvenile period: years)Size of plants is big, around several meters to tens of meters in height.Large and complex genome: there are around several hundred of chromosomes.Hard to breed, generate mutants and get seeds
41 Tissue culture and high-through-put approaches make breakthrough to study bamboo
42 Tissue culture reduces size and juvenile period, and generates lots of mutants (variants)
