DELLA proteins positively regulate seed size in Arabidopsis

DELLA proteins positively regulate seed size in Arabidopsis - PubMed

Our results indicate that DELLA proteins are involved in the control of seed size and suggest that modulation of the DELLA-dependent pathway could be used to ...

Here, we provide previously unreported evidence for the role of DELLA proteins, key repressors of gibberellin responses, in the maternal control of seed size.

DELLA proteins positively regulate seed size in Arabidopsis - PMC

In Arabidopsis, DELLA protein activity induces cell proliferation in ovule integuments that results in the development of larger ovules and, consequently, ...

(PDF) DELLA proteins positively regulate seed size in Arabidopsis

Seed size is coordinately regulated by signals of maternal and zygotic tissues that control the growth of the seed coat, endosperm, and embryo. Here, we provide ...

DELLA proteins positively regulate seed size inArabidopsis

This leads to an increase in ovule size and, in turn, to an increase in seed size. Moreover, DELLA activity promotes increased seed size by inducing the ...

SMAX1 interacts with DELLA protein to inhibit seed germination ...

The main cue for Arabidopsis germination is GAs. GA signaling is sensed by α/β hydrolase-type receptors, which degrade collections of DELLA ...

Transcription factor DIVARICATA1 positively modulates seed ...

A MYB-like transcription factor positively modulates seed germination in response to salinity stress by regulating the expression of germination-associated.

KELCH F-BOX protein positively influences Arabidopsis seed ...

Seeds employ sensory systems that assess various environmental cues over time to maximize the successful transition from embryo to seedling.

Natural variation in SSW1 coordinates seed growth and nitrogen ...

SSW1 encodes AAP8. AAP8/SSW1 has been described to affect seed development in Arabidopsis, but its role in seed size control has not been studied in detail.

OsDA1 positively regulates grain width in rice - ScienceDirect.com

The recently identified ubiquitin-related protein DA1 in Arabidopsis plays a pivotal role in the regulation of seed size through intricate molecular mechanisms ...

Arabidopsis CBF3 and DELLAs positively regulate each other in ...

Our present work shows that CBF3 shares the similar repression of bioactive gibberellin (GA) as well as upregulation of DELLA proteins with CBF1 and -2.

DELLA protein functions as a transcriptional activator through the ...

DELLA protein is a key negative regulator of gibberellin (GA) signaling. Although how DELLA regulates downstream gene expression remains unclear ...

A Pivotal Role of DELLAs in Regulating Multiple Hormone Signals

(A) DELLA, ABI3, and ABI5 proteins mediate GA and ABA signaling to activate SOM expression, a key repressor of seed germination. (B) BZR1, ARF6, and PIF4 form a ...
