Phyllotaxy and Development
The arrangement of leaves around a stem is known as this.
What is phyllotaxy?
This biome is characterized by permafrost and low-growing vegetation.
What is the tundra?
QTL stands for this.
What is quantitative trait locus?
Monocots typically possess this type of leaf venation.
What is parallel venation?
Phytochromes primarily absorb these wavelengths of light.
What are red and far-red wavelengths?
A spiral phyllotactic pattern often approximates this mathematical sequence.
What is the Fibonacci sequence?
Plants in deserts commonly reduce water loss through this physiological process.
What is stomatal closure?
Traits controlled by multiple genes with continuous variation are described as this.
What are quantitative traits?
The vascular bundles in monocot stems are arranged in this manner.
What is scattered?
This photoreceptor is most associated with blue light responses.
What is cryptochrome?
This plant hormone is primarily responsible for positioning new leaf primordia at the shoot apical meristem.
What is auxin?
Abiotic stress refers to stress caused by these types of environmental factors.
What are nonliving factors?
A genomic region repeatedly associated with increased plant height across populations would likely contain this.
What is a QTL?
This embryonic feature distinguishes monocots from dicots.
What is a single cotyledon?
Flowering triggered by seasonal day length is known as this.
What is photoperiodism?
A mutation disrupting auxin transport would most directly alter this developmental feature.
What is phyllotactic patterning?
Excess soil salinity creates this immediate challenge for plant roots.
What is osmotic stress?
Tomato and corn are frequently used in genetic studies because they serve as these.
What are model crop systems?
Grasses are evolutionarily successful in part because their basal meristems allow this advantage.
What is regrowth after grazing?
Long-day plants flower when daylight exceeds this threshold.
What is a critical photoperiod?
If organ initiation repeatedly occurs at the same location on the meristem, the most likely defect involves this process.
What is auxin redistribution/polar transport?
A plant preconditioned to mild drought stress later survives severe drought more effectively due to this phenomenon.
What is stress acclimation/priming?
If a trait shows high environmental influence but low heritability, selection for that trait becomes this.
What is less effective/difficult?
A plant with fibrous roots, parallel veins, and floral parts in multiples of three is most likely this.
What is a monocot?
A mutant unable to detect changes in day length would most likely exhibit defects in this developmental process.
What is flowering time regulation?
