Data from: Association mapping for phenology and plant architecture in maize shows higher power for developmental traits compared with growth influenced traits
Plant architecture, phenology and yield components of cultivated plants have repeatedly been shaped by selection to meet human needs and adaptation to different environments. Here we assessed the genetic architecture of 24 correlated maize traits that interact during plant cycle. Overall, 336 lines were phenotyped in a network of 9 trials and genotyped with 50K single-nucleotide polymorphisms. Phenology was the main factor of differentiation between genetic groups. Then yield components distinguished dents from lower yielding genetic groups. However, most of trait variation occurred within group and we observed similar overall and within group correlations, suggesting a major effect of pleiotropy and/or linkage. We found 34 quantitative trait loci (QTLs) for individual traits and six for trait combinations corresponding to PCA coordinates. Among them, only five were pleiotropic. We found a cluster of QTLs in a 5 Mb region around Tb1 associated with tiller number, ear row number and the first PCA axis, the latter being positively correlated to flowering time and negatively correlated to yield. Kn1 and ZmNIP1 were candidate genes for tillering, ZCN8 for leaf number and Rubisco Activase 1 for kernel weight. Experimental repeatabilities, numbers of QTLs and proportion of explained variation were higher for traits related to plant development such as tillering, leaf number and flowering time, than for traits affected by growth such as yield components. This suggests a simpler genetic determinism with larger individual QTL effects for the first category.
Reproductive and vegetative phenology database of two progenies of Euterpe oleracea Mart. planted in the Amazon estuary
<p><span>During the period from May/2009 to April/2013, we monitored the reproductive and vegetative phenophases of two progenies of <em>Euterpe oleracea</em> Mart., planted in the floodplain forest of the Amazon estuary. We carried out prospecting on the east and west coast of the Amazon estuary with the aim of selecting native açaí palm matrices with phenotypic production characteristics during the period of low natural production of this palm.</span></p>

Figure 2 in An exploratory study of bumble bee (Bombus) phenologies and plant interactions in agricultural landscapes in central Georgia, USA
Figure 2. Bombus griseocollis captures averaged by week at three sites near Athens, Georgia, USA. HF = Durham Horticulture Farm in Watkinsville, GA; WG = Woodland Gardens in Athens, GA; SV = Spring Valley EcoFarms in Athens, GA. No surveys were conducted during the week of 28 June due to a lack of available person-hours.
