Synthetic Raphanobrassica Genome Reveals Functional and Evolutionary Insights Into Clubroot Resistance Genes on Chromosome R5

Plant Biotechnology Journal, EarlyView.
ABSTRACT Clubroot, a severe soil‐borne disease caused by Plasmodiophora brassicae, poses a severe threat to global production of Brassicaceae oilseed crops and vegetables. To date, there has been a serious lack of clubroot‐resistant germplasms in Brassica napus (AACC), necessitating the urgent development of novel disease‐resistant germplasm.

Drought and Herbivory Drive Physiological and Phytohormonal Changes in Soybean (Glycine max Merril): Insights From a Meta‐Analysis

Plant, Cell &Environment, EarlyView.
ABSTRACT With climate change, abiotic and biotic stresses such as drought and herbivory are predicted to further diminish agricultural productivity. Soybean (Glycine max [L.] Merrill), a crop of global economic importance, is vulnerable to both. However, the interactive effects of drought and herbivory on soybeans haven't been explored, especially ...

Relative importance of biotic and abiotic soil components to plant growth and insect herbivore population dynamics [PDF]

, 2010
Background: Plants are affected by several aspects of the soil, which have the potential to exert cascading effects on the performance of herbivorous insects. The effects of biotic and abiotic soil characteristics have however mostly been investigated in

How Cabbage Aphids Brevicoryne brassicae (L.) Make a Choice to Feed on Brassica napus Cultivars

Insects, 2019
Plant resistance to aphids might be present in different plant tissues, such as the epidermis, mesophyll and phloem, but not all of them play a key role in determining the feeding preference of aphids.

Organ‐specific terpenoid responses in Tanacetum vulgare are chemotype‐dependent

Plant Biology, EarlyView.
Common tansy varieties defend differently: some boost root chemicals against soil pests, while others release stronger leaf scents against aphids. Abstract Specialized metabolites such as terpenoids are known to mediate plant defence mechanisms. However, how terpenoid diversity governs inducible chemistry across organs remains poorly understood.

Organic Horticultural Seed Trials in Wales [PDF]

, 2004
Under the organic standards, producers are required to use organic seed. However, a derogation can be obtained from the appropriate certification body that allows the use of (untreated) non organic seed where appropriate organic material is not available.

Impact of Simulated Insect Defoliation and Timing of Injury on Cabbage Yield in Minnesota [PDF]

, 2018
In 1992 and 1994, field studies were done to assess the tolerance of transplanted cabbage to simulated insect defoliation and to determine if the defoliation level and growth stage at which defoliation begins influences final yield.
