From screening a population of Arabidopsis overexpression lines, two Arabidopsis genes were identified, EFO1 (early flowering by overexpression 1) and EFO2, that confer early flowering when overexpressed. The two genes encode putative WD-domain proteins which share high sequence similarity and constitute a small subfamily. Interestingly, the efo2-1 loss-of-function mutant also flowered earlier ...

a number of 36 varieties of rice were compared for different traits. the correlation coefficient of grain yield with tiller number, harvest index, length of grain, ratio of length to width of grain, amylase content, days to 50 percent flowering and days to full maturity were positive and significant (p

The rice (Oryza sativa) E3 ligase SPOTTED LEAF11 (SPL11) negatively regulates programmed cell death and disease resistance. We demonstrate here that SPL11 also regulates flowering via interaction with SPIN1 (for SPL11-interacting protein1), a Signal Transduction and Activation of RNA family member. SPIN1 binds RNA and DNA in vitro and interacts with SPL11 in the nucleus. Spl11 mutants have dela...

The MADS box gene, AGAMOUS-LIKE 20 (AGL20), integrates environmental and endogenous flowering signals in Arabidopsis thaliana. In order to determine if its role is conserved in other plants, we isolated AGL20 orthologs from Brassica campestris, Cardamine flexuosa and Draba nemorosa. The putative amino acid sequences of the orthologs were 94 to 97% identical. We analyzed the flowering phenotype ...

Shifting flowering phenology with rising temperatures is occurring worldwide, but the rarity of co-occurring long-term observational and temperature records has hindered the evaluation of phenological responsiveness in many species and across large spatial scales. We used herbarium specimens combined with historic temperature data to examine the impact of climate change on flowering trends in 1...
