Do plants need tropism in order for photosynthesis to occur? Secretion of which hormone is controlled by a positive-feedback mechanism? In plants, what is the stroma? What controls the production of a protein? What glands produces hormones that help to regulate body metabolism?
In plants, the initiation of flowering in response to photoperiod is triggered by changes in what chemical? a) ethylene b) auxin c) gibberellic acid d) phytochrome e) cytokinin Which of the following procedures is an appropriate negative control for testing the hypothesis that air contains brea...
mutant plants lacking auxin exporters.aContribution of ABCB-, AUX1/LAX-, and PIN-type transporters in main auxin (IAA) transport routes (arrows) of seedling roots and hypocotyls, where auxin research has been focused. Concerted actions indicating a shared, overlapping function of two (or...
Grafting has been a long-standingtechnique used to improve crop production and provide tolerance to biotic stresses, including soil-borne pathogens, as well as tolerance to abiotic stresses, such as cold, salinity, drought, and heavy metals. Currently, beyond its use in horticultural production, gr...
What do you mean by influx of ions in plants? Uptake of K+ ionsis referred as influx of K+ ions into guard cells and outward movement of H+ ions is referred as efflux of H+ ions. This is an active ionic exchange and requires ATP energy and cytokinin (a plant hormone). ...
There are still many questions unanswered in this topic; for instance: Do all plant PHT1 members undergo oligomerization? Does oligomerization significantly affect both affinity and specificity? Are the potential oligomerization events responsible for the variation in the extent of enhanced Pi accumulation...
The expression of the seven genes in turnip and Pak choi at several timepoints between 7 and 28 DAS is presented in Fig.7. Two candidate genesBra-FLOR1(Floral transition at the meristem) andBra-CYP735A2(Cytokinintrans-hydroxylase) are both located in turnip selective sweeps and hypocotyl-tube...
How do plant hormones affect plant growth and development? Discuss the factors which influence growth. What is the significance of secondary growth in plants? What factors increase transpiration in plants? What is the role of hematopoietic growth factors? How does the meristem help plant growth? Wh...
What process in plants is due to capillary action? What are plant hormones called? Which of these plant hormones is NOT typically considered a growth-promoting substance? A) abscisic acid B) cytokinin C) gibberellin D) auxin E) brassinosteroids Which causes plants to respond positively to sunligh...
