Embryogenesis

Question 1

Sporophytic phases

Answer 1

Embryogenesis
Vegetative development
Reproductive development

Question 2

Embryogenesis stages

Answer 2

Zygotes stage
Globular stage
Heart stage
Torpedo stage
Mature stage

Question 3

Apical Cell vs basal Cell

Answer 3

A: cytoplasmically dense
B: longer and vacuolated

Question 4

Auxin in embryogenesis

Answer 4

Mobile chemical signal during embryogenesis

Question 5

PIN proteins

Answer 5

Class of auxin transporters

Question 6

GNOM protein

Answer 6

Establish polar distribution of auxin efflux proteins

Question 7

GN

Answer 7

Guanine nucleotide exchange factor

Polarized localization of PIN proteins

Question 8

MONOPTEROS

Answer 8

Encodes a transcription factor activated by auxin

Question 9

MP gene

Answer 9

Encodes for an auxin response factor
-regulate transcription of genes involved in auxin responses
Regulates genes that guide auxin-dependent vascular development
(Mutants lack basal domains of embryo-defective in vascular patterning)

Question 10

WOODEN LEG gene

Answer 10

Cytokinin response receptor
Mutants develop xylem but not phloem
Establishes radial pattern elements

Question 11

Apical-basal and radial axes mechanisms

Answer 11

A combination of hormone signaling and transcriptional control

Question 12

Normal roots auxin location

Answer 12

Quiescent center

Question 13

CUC

Answer 13

Cup shaped cotyledon

-NAC transcription factor
