TL;DR: Four cut rose cultivars which were bred in Korea and were either resistant or sensitive to aphid infestation at different flower developmental stages were compared and proteins related to ubiquitin metabolism and the stress response were differentially expressed.
Abstract: The rose is one the most commercially grown and costly ornamental plants because of its aesthetic beauty and aroma. A large number of pests attack its buds, flowers, leaves, and stem at every growing stage due to its high sugar content. The most common pest on roses are aphids which are considered to be the major cause for product loss. Aphid infestations lead to major changes in rose plants, such as large and irregular holes in petals, intact leaves and devouring tissues. It is hypothesized that different cut rose cultivars would have different levels of sensitivity or resistance to aphids, since different levels of infestation are observed in commercially cut rose production greenhouses. The present work compared four cut rose cultivars which were bred in Korea and were either resistant or sensitive to aphid infestation at different flower developmental stages. An integrative study was conducted using comprehensive proteome analyses. Proteins related to ubiquitin metabolism and the stress response were differentially expressed due to aphid infestation. The regulations and possible functions of identified proteins are presented in detail. The differential expressions of the identified proteins were validated by immunoblotting and blue native page. In addition, total sugar and carbohydrate content were also observed.

TL;DR: Scale insect, thrips, black spot and crown gall were classified as important pests and diseases on roses in this area, but some pesticides and other materials used by the farmers to control either pests or diseases were ineffective, especially in controlling armored scale insect and crown Gall.
Abstract: Rose is one of the most important ornamental plants in Indonesia Almost 5702% of the national cut rose’s demand was supplied from East Java, mainly from Batu However, in the production process, there are various problems, especially pest and disease damages In this regard, a study was conducted to determine recent status of the pests and diseases on roses in cultivation center of Batu, East Java Observation was carried out in the farmers’ field randomly, from October to December 2014 Observation was performed on type and damage intensity of the pests and diseases The pests and plant damage were sampled for further identification An interview was made with some farmers to get secondary data about the type and the importance of the pests and diseases as well as the effort for controlling them The result showed that some pests and diseases found included aphid, armored scale insect, spider mite, thrips, black spot, crown gall and powdery mildew Based on morphological identification, there were two families of armored scale insect, ie, Coccidae and Diaspidae The highest damage intensity was due to armored scale insect, thrips, black spot and crown gall with the percentage of damage intensities of 5050%, 2000%, 4550% and 6500%, respectively Based on those data, scale insect, thrips, black spot and crown gall were classified as important pests and diseases on roses in this area Some pesticides and other materials like petroleum oil and detergent were used by the farmers to control either pests or diseases, but they were ineffective, especially in controlling armored scale insect and crown gall Keywords: Cut roses, pest, disease, inventory, observation, status

TL;DR: Maria Rodale, 32-year-old heir apparent to Rodale Press (Runners' World, Bicycling, Organic Gardening, Prevention Magazine) is about to begin a sabbatical to prepare herself for her as-yet-to-be-determined leadership role.
Abstract: DOESN'T MEET STANDARDSMaria Rodale, 32-year-old heir apparent to Rodale Press (Runners' World, Bicycling, Organic Gardening, Prevention Magazine) is about to begin a sabbatical to prepare herself for her as-yet-to-be-determined leadership role. She must consider several challenges: ascertaining her new job and convincing the chairman (her mother) to share power, gaining the confidence of more-experienced senior management, navigating family (shareholder) politics, and charting a new corporate direction and strategy.
