Functional mapping of gravitropism and phototropism for a desert tree, Populus euphratica
Frontiers in Bioscience-Landmark, 2021 Background: Plants have evolved the dual capacity for maximizing light assimilation through stem growth (phototropism) and maximizing water and nutrient absorption through root growth (gravitropism).

The PIN-FORMED (PIN) protein family of auxin transporters [PDF]
, 2009 The PIN-FORMED (PIN) proteins are secondary transporters acting in the efflux of the plant signal molecule auxin from cells. They are asymmetrically localized within cells and their polarity determines the directionality of intercellular auxin flow.

Frontiers in Cell and Developmental Biology, 2020 European species of Nuphar are amongthe most accessible members of the basal angiosperm grade, but detailed studies using scanning electron microscopy are lacking. We provide such data and discuss them in the evolutionary context. Dorsiventral monopodial

Cellular and physiological functions of SGR family in gravitropic response in higher plants
Journal of Advanced ResearchBackground: In plants, gravity directs bidirectional growth; it specifies upward growth of shoots and downward growth of roots. Due to gravity, roots establish robust anchorage and shoot, which enables to photosynthesize.

Bundling up the Role of the Actin Cytoskeleton in Primary Root Growth
Frontiers in Plant Science, 2021 Primary root growth is required by the plant to anchor in the soil and reach out for nutrients and water, while dealing with obstacles. Efficient root elongation and bending depends upon the coordinated action of environmental sensing, signal ...

Gravitropism in Higher Plant Shoots [PDF]
Plant Physiology, 1984 Cross and longitudinal sections were prepared for light microscopy from vertical control plants (Xanthium strumarium L. Chicago strain), free-bending horizontal stems, plants restrained 48 hours in a horizontal position, and plants restrained 48 hours and then released, bending immediately about 130 degrees .

Analysis of chlorophyll fluorescence reveals stage specific patterns of chloroplast-containing cells during Arabidopsis embryogenesis [PDF]
, 2010 http://www.scielo.cl/scielo.php?script=sci_arttext&pid=S0716-97602010000100012&lng=es&nrm=isoThe basic body plan of a plant is established early in embryogenesis when cells differentiate, giving rise to the apical and basal regions of the embryo.

Gravitropic Analysis of Tomato Seedlings using Time Lapse Video Imaging
Bio-Protocol, 2015 Plants use gravity as a guide for growth and development. Gravitropism, a gravity-directed growth process, directs upward shoot movement for efficient photosynthesis and gaseous exchange. In addition, it also directs downward growth of roots in soil, for
