Evolutionary variation in MADS-box dimerization affects floral development and protein abundance in maize
<p>Interactions between MADS-box transcription factors are critical in the regulation of floral development, and shifting MADS-box protein-protein interactions are predicted to have influenced floral evolution. However, precisely how evolutionary variation in protein-protein interactions affects MADS-box protein function remains unknown. To assess the impact of changing MADS-box protein-protein interactions on transcription factor function, we turned to the grasses, where interactions between B-class MADS-box proteins vary. We tested the functional consequences of this evolutionary variability using maize as an experimental system. We found that differential B-class dimerization was associated with subtle, quantitative differences in stamen shape. In contrast, differential dimerization resulted in large-scale changes to downstream gene expression. Differential dimerization also affected B-class complex composition and abundance, independent of transcript levels. This indicates that differential B-class dimerization affects protein degradation, revealing an important consequence for evolutionary variability in MADS-box interactions. Our results highlight complexity in the evolution of developmental gene networks - changing protein-protein interactions could affect not only the composition of transcription factor complexes, but also their degradation and persistence in developing flowers. Our results also show how coding change in a pleiotropic master regulator could have small, quantitative effects on development.</p>

Effects of elevated temperature and CO2 concentration on floral development and sex differentiation in Morus alba L.
<p>The effects of global warming on floral development have been reported in many plants, but knowledge of floral development regarding gender and sex differentiation under elevated temperature, CO<sub>2</sub> concentration and their combination remains limited. So here we analysed flowering phase, sex ratio, floral morphology and biomass, total carbon and nitrogen data in male and female inflorescences (flowers) of <em>Morus alba </em>L. to determine whether and how they differ.</p> <p>This excel file contains the raw data for each data table and figure within a manuscript submitted to Annals of Forest Science.</p> <p> </p> <p> </p> <p> </p> <p> </p>

Developing floral-baited traps to survey pollinators in insect-pollinated crops: findings from an oil palm case study
<p>In this study, we used oil palm as a case study system to trial a new trap design to selectively survey pollinators of insect pollinated crops. The trap consisted of a pan trap baited with half a male oil palm inflorescence at anthesis, with varying number of flowers open. To assess effectiveness of the trap across different environments, we set pairs of baited and non-baited control pan traps in habitat conditions ranging from young to mature palms, and continuous blocks of oil palm to strips of oil palm around rivers in industrial oil palm plantations in Riau, Indonesia. We identified all arthropods collected to order level or lower. </p>
