Nucleic Acid Metabolism in Peanut Cotyledons [PDF]

Plant Physiology, 1965
Peanutt seeds are a unique material for the study of nutcleic acid metabolism. At the onset of germinatioln RNA synthesis is initiated in the cotyledons an(l the content per cotyledon doubles by a week after plantinig (4, 9). Subsequently the RNA content rapidly declines with age of the plant (4).

The Dehydratase ADT3 Affects ROS Homeostasis and Cotyledon Development1[OPEN]

Plant Physiology, 2016
Arabidopsis seedlings mutated in the phenylalanine biosynthetic enzyme ADT3 cannot buffer reactive oxygen species, produce a defective cuticle, and display impaired cotyledon development.

Effects of bioinsecticide exposure route on aphids and their natural enemies in oilseed rape

Pest Management Science, EarlyView.
Fatty acids, silicone polymers and surfactants reduced aphid numbers but caused natural enemy mortality under direct exposure, while minimal residual activity suggests potential for targeted, compatible use in integrated pest management. Abstract BACKGROUND Myzus persicae Sulzer and Brevicoryne brassicae L.

Similarities and Differences of Photosynthesis Establishment Related mRNAs and Novel lncRNAs in Early Seedlings (Coleoptile/Cotyledon vs. True Leaf) of Rice and Arabidopsis

Frontiers in Genetics, 2020
Photosynthesis uses sunlight and carbon dioxide to produce biomass that is vital to all life on earth. In seed plants, leaf is the main organ for photosynthesis and production of organic nutrients.

Temporal dynamics of co‐inoculation of Leptosphaeria maculans and Leptosphaeria biglobosa determine interspecific competition and disease development on oilseed rape

Pest Management Science, EarlyView.
This study provides evidence that the timing of co‐inoculation of Leptosphaeria maculans and Leptosphaeria biglobosa determine the outcome of interspecific competition and disease development on their host oilseed rape. Abstract BACKGROUND Phoma stem canker is one of the most economically damaging diseases of oilseed rape, caused by co‐existing fungal ...

Estudos morfoanatômicos da semente e da plântula de espécies de Anileiras (Indigofera L., Leguminosae) Morpho-anatomical studies of seeds and seedlings of wild indigo, "anileira", Indigofera- Leguminosae

Acta Botânica Brasílica, 2010
O nome popular "anileira" designa Indigofera anil L., I. suffruticosa Mill. e I. truxillensis Kunth, muito semelhantes quanto à morfologia externa. Este trabalho teve por objetivo avaliar se caracteres da semente e plântula apresentavam valor diagnóstico

Seedling resistance and chemical defenses against Psylliodes chrysocephala: the roles of seed age and sinapinic acid in Sinapis alba and Brassica napus

Pest Management Science, EarlyView.
The cabbage stem flea beetle (Psylliodes chrysocephala) is a major pest of winter oilseed rape (Brassica napus). We tested B. napus and Sinapis alba seedlings for feeding resistance and underlying chemical defenses. S. alba was least damaged, while metabolite profiles revealed resistance‐linked compounds, highlighting breeding potential for insect ...

CLE19 expressed in the embryo regulates both cotyledon establishment and endosperm development in Arabidopsis

Journal of Experimental Botany, 2015
Highlight CLE19, as an embryo-expressed CLV3/ESR gene, regulates cotyledon establishment in embryos and nuclear proliferation and cellularization in the endosperm.

Determining frequencies of fungicide resistance in Leptosphaeria maculans that render demethylation inhibitor fungicides ineffective in the field

Pest Management Science, EarlyView.
As little as 1–10% of the population is needed to be resistant for demethylation inhibitor fungicides to be rendered ineffective. Following a single round of selection, the frequency increases by more than 15% with limited fitness penalty detected when no selection is present.
