Data from: Response to persistent er stress in plants: a multiphasic process that transitions cells from prosurvival activities to cell deathRenu Srivastava, Zhaoxia Li, Giulia Russo, Jie Tang, Ran Bi, Usha Muppirala, Sivanandan Chudalayandi, Andrew Severin, Mingze He, Samuel I. Vaitkevicius, Carolyn J. Lawrence-Dill, Peng Liu, Ann E. Stapleton, Diane C. Bassham, Federica Brandizzi & Stephen H. Howell
The unfolded protein response (UPR) is a highly conserved response that protects plants from adverse environmental conditions. The UPR is elicited by endoplasmic reticulum (ER) stress, in which unfolded and misfolded proteins accumulate within the ER. Here, we induced the UPR in maize (Zea mays) seedlings to characterize the molecular events that occur over time during persistent ER stress. We found that a multiphasic program of gene expression was interwoven among other cellular events, including...
Plant reproduction relies on transfer of pollen from anthers to stigmas, and the majority of flowering plants depend on biotic or abiotic agents for this transfer. A key metric for characterizing if pollen receipt is insufficient for reproduction is pollen limitation, which is assessed by pollen supplementation experiments. In a pollen supplementation experiment, fruit or seed production by flowers exposed to natural pollination is compared to that following hand pollination either by pollen supplementation (i.e....
Data from: Dynamic genomic architecture of mutualistic cooperation in a wild population of MesorhizobiumStephanie S. Porter, Joshua Faber-Hammond, Angeliqua P. Montoya, Maren L. Friesen & Cynthia Sackos
Research on mutualism seeks to explain how co-operation can be maintained when uncooperative mutants co-occur with cooperative kin. Gains and losses of the gene modules required for co-operation punctuate symbiont phylogenies and drive lifestyle transitions between cooperative symbionts and uncooperative free-living lineages over evolutionary time. Yet whether uncooperative symbionts commonly evolve from within cooperative symbiont populations or from within distantly related lineages with antagonistic or free-living lifestyles (i.e., third-party mutualism exploiters or parasites), remains controversial....

Data from: The impact of hurricanes Irma and Maria on the forest ecosystems of Saba and St. Eustatius, northern CaribbeanMaarten B. Eppinga, Carolyn A. Pucko. & Carolyn A. Pucko
In September 2017, Irma became the first recorded category 5 hurricane to hit the Caribbean Windward Islands. The second category 5, Maria, followed two weeks later. In November 2017, we assessed the structural impact of this disturbance on highly valued Caribbean forest ecosystems. We recorded the status of 935 tree stems on Saba and St. Eustatius in stands at different elevations. Tree damage was substantial on both islands, with 93% of stems being defoliated, 84%...
