Exogenously Applied Polyamines Reduce Reactive Oxygen Species, Enhancing Cell Division and the Shoot Regeneration from Brassica oleracea L. var. capitata Protoplasts

open access: yesAgronomy, 2021
Polyamines (PAs) are organic molecules that are found in plants and animals. In plants, they are involved in the regulation of cellular growth, apoptosis, rooting, flower development, and stress responses.

The HY5-PIF regulatory module coordinates light and temperature control of photosynthetic gene transcription [PDF]

open access: yes, 2014
The ability to interpret daily and seasonal alterations in light and temperature signals is essential for plant survival. This is particularly important during seedling establishment when the phytochrome photoreceptors activate photosynthetic pigment ...

SMAX1 potentiates phytochrome B-mediated hypocotyl thermomorphogenesis

open access: yes, 2022
SMAX1 functions as a "thermosensitizer" that modulates the thermal sensitivity of plant morphogenesis. Plant thermosensors help optimize plant development and architecture for ambient temperatures, and morphogenic adaptation to warm ...

Influence of altered temperatures on allelopatic properties of Amaranthus cruentus L.

open access: yesActa Agriculturae Slovenica, 2017
The relationships between allelochemicals and environmental factors are a key factor for the growth of plants under rotation. We investigated the allelopathic potential of Amaranthus cruentus L, grown under different temperature conditions in in vitro ...

THE GROWTH CAPACITY OF THE SUNFLOWER HYPOCOTYL [PDF]

open access: yesPlant Physiology, 1951
agar to which indole-3-acetic acid (IAA) had been added, (3) on sucrose mineral agar after inoculation of the fragment with crown-gall bacteria. Five aspects of growth were measured: increase in length, breadth, fresh and dry weight, and production of adventitious roots. Sunflower seeds var.

Circumnutations of Sunflower Hypocotyls in Satellite Orbit [PDF]

open access: yesPlant Physiology, 1990
The principal objective of the research reported here was to determine whether a plant's periodic growth oscillations, called circumnutations, would persist in the absence of a significant gravitational or inertial force. The definitive experiment was made possible by access to the condition of protracted near weightlessness in an earth satellite ...

The preprophase band is dispensable for robust cell division orientation in wood-forming cambium stem cells. [PDF]

open access: yesNew Phytol
Characterization of periclinal and anticlinal cell divisions in dividing cambium stem cells (CSCs). (a) Scheme indicating periclinal and anticlinal cell divisions in CSCs in the Arabidopsis hypocotyl. The orange dashed ring in the middle panel represents the cambium area. The orange cuboids represent individual CSCs.

Gibberellin Response in Lettuce Hypocotyl Sections [PDF]

open access: yesPlant Physiology, 1975
Excised lettuce (Lactuca sativa L.) hypocotyl sections retain the ability to elongate in response to gibberellic acid (GA(3)) addition. In 48 hr at 30 C a GA(3)-treated segment more than doubles while a control segment elongates less than 50%. Auxin has no detectable effect on this system.

Organospecific reactions of yellow lupin seedlings to lead

open access: yesActa Societatis Botanicorum Poloniae, 2014
Changes caused by lead, supplied in the form of Pb(NO3)2, in roots and hypocotyls of 4 day old yellow lupin (Lupinus luteus L. cv. ventus) seedlings have been analyzed using a transmission electron microscope and polyacrylamide gel electrophoresis (PAGE).
