A Petunia homeodomain-leucine zipper protein, PhHD-Zip, plays an important role in flower senescence. [PDF]

open access: yes, 2014
Flower senescence is initiated by developmental and environmental signals, and regulated by gene transcription. A homeodomain-leucine zipper transcription factor, PhHD-Zip, is up-regulated during petunia flower senescence. Virus-induced gene silencing of

Cytokinins [PDF]

open access: yesThe Plant Cell, 2010
Summary Cytokinins promote shoot development, delay leaf senescence, contribute to stress and pathogen responses, and serve as important signals to integrate growth rates throughout the plant. The identification of genes controlling CK synthesis and signaling has allowed us to understand the molecular basis for some of these effects with

Ethylene-independent promotion of photomorphogenesis in the dark by cytokinin requires COP1 and the CDD complex [PDF]

open access: yes, 2019
The transition of skotomorphogenesis to photomorphogenesis is induced by the perception of light, and is characterized by the inhibition of hypocotyl elongation and opening of cotyledons.

The Cytokinin Complex Associated With Rhodococcus fascians: Which Compounds Are Critical for Virulence?

open access: yesFrontiers in Plant Science, 2019
Virulent strains of Rhodococcus fascians cause a range of disease symptoms, many of which can be mimicked by application of cytokinin. Both virulent and avirulent strains produce a complex of cytokinins, most of which can be derived from tRNA degradation.

In vitro shoot regeneration from seedling explants in Brassica vegetables: Red cabbage, broccoli, Savoy cabbage and cauliflower [PDF]

open access: yesArchives of Biological Sciences, 2010
Brassica oleracea varieties (red cabbage, broccoli, Savoy cabbage and cauliflower) were tested for their ability to regenerate shoots in vitro. Cotyledon, hypocotyl and root explants of 7 day-old seedlings were incubated on Murashige and Skoog's (MS ...

Artificial Seed Production from Encapsulated Microshoots of Cauliflower (Brassica oleraceae var botrytis) [PDF]

open access: yes, 2012
A cost effective protocol for the production of cauliflower microshoots suitable for encapsulation was designed. Microshoots were encapsulated in sodium chloride matrices. The use of 2% of sodium alginate and 15 g/L of dehydrate calcium chloride produced

Endogenous cytokinin overproduction modulates ROS homeostasis and decreases salt stress resistance in Arabidopsis thaliana

open access: yesFrontiers in Plant Science, 2015
Cytokinins in plants are crucial for numerous biological processes, including seed germination, cell division and differentiation, floral initiation and adaptation to abiotic stresses.

Hormone Profiles and Antioxidant Activity of Cultivated and Wild Tomato Seedlings under Low-Temperature Stress

open access: yesAgronomy, 2021
Low temperature is a major limiting factor for the growth and reproduction of some plant species, such as tomato. So far, few studies have been conducted on the effects of low temperature, and the mechanisms of plants’ response to this type of stress is ...

Environmental, developmental, and genetic factors controlling root system architecture [PDF]

open access: yes, 2014
A better understanding of the development and architecture of roots is essential to develop strategies to increase crop yield and optimize agricultural land use.

The effect of various cytokinins and other factors on the protonemal celi divisions and the induction of gametophores in Ceratodon purpureus

open access: yesActa Societatis Botanicorum Poloniae, 2015
The cytokinins specifically induce formation of gametophore buds in the protonema of Ceratodon purpureus. The responsein this species is less sensitive than in Funaria hygrometrica, but is independent of light.
