Plant genetic transformation: achievements, current status and future prospects

Plant Biotechnology Journal, EarlyView.
Summary Regeneration represents a fundamental biological process wherein an organism's tissues or organs repair and replace themselves following damage or environmental stress. In plant systems, injured tree branches can regenerate adventitious buds and develop new crowns through propagation techniques like cuttings and canopy pruning, while transgenic

Plant Morphology and a Phytochrome B Model Reveal That the Effects of Far‐Red Light on Shade‐Avoidance‐Like Responses Persist Under High Light Intensity

Plant, Cell &Environment, EarlyView.
ABSTRACT Several studies have concluded that high photon flux density (PFD) attenuates the effects of the red (R; 600–699 nm) to far‐red (FR; 700–750 nm) light ratio on morphology. However, the suppressive effects can depend on individual wavebands that modulate photoreceptor activity. We postulated that morphological responses of shade‐avoiding plants

Functional alleles of the flowering time regulator FRIGIDA in the Brassica oleracea genome

BMC Plant Biology, 2012
Background Plants adopt different reproductive strategies as an adaptation to growth in a range of climates. In Arabidopsis thaliana FRIGIDA (FRI) confers a vernalization requirement and thus winter annual habit by increasing the expression of the MADS ...

CSGDN: Contrastive Signed Graph Diffusion Network for Predicting Crop Gene-phenotype Associations [PDF]

Positive and negative association prediction between gene and phenotype helps to illustrate the underlying mechanism of complex traits in organisms. The transcription and regulation activity of specific genes will be adjusted accordingly in different cell types, developmental stages, and physiological states.

Intraspecific chemical variation of Tanacetum vulgare affects plant growth and reproductive traits in field plant communities

Plant Biology, EarlyView.
We designed an experiment to test the effects of intraspecific plant chemodiversity at plant and plot level on plant performance, and showed that chemodiversity significantly shapes plant growth and reproductive outputs, with most pronounced interactions between chemotype and plot‐level chemotype richness on reproductive traits..

Exogenous stimulation of Tanacetum vulgare roots with pipecolic acid leads to tissue‐specific responses in terpenoid composition

Plant Biology, EarlyView.
Tissue‐specific changes in terpenoid patterns in tansy are induced by simulated induction of systemic acquired resistance using pipercolic acid. Abstract Tanacetum vulgare L., tansy, is a perennial plant with highly variable terpenoid composition, with mono‐ and sesquiterpenoids being the most abundant.

A complex recombination pattern in the genome of allotetraploid Brassica napus as revealed by a high-density genetic map.

PLoS ONE, 2014
Polyploidy plays a crucial role in plant evolution. Brassica napus (2n = 38, AACC), the most important oil crop in the Brassica genus, is an allotetraploid that originated through natural doubling of chromosomes after the hybridization of its progenitor ...

Effects of diversified volatile profiles on olfactory orientation of flea beetles Phyllotreta spp. and the diamondback moth Plutella xylostella

Plant Biology, EarlyView.
Diversifying the crop volatile organic compound profile can alter pest orientation: flea beetles were less attracted to chemical cues of the cabbage–faba bean mix than to those from cabbage alone, while diamondback moths remained equally attracted to both cues.

Resistance of Cabbage (Brassica oleracea capitata Group) Crops to Mamestra brassicae

Journal of Economic Entomology, 2010
Twenty-one cabbage (Brassica oleracea capitata group) varieties, including 16 local varieties and five commercial hybrids, were screened for resistance to the moth Mamestra brassicae L. under natural and artificial conditions in northwestern Spain. Resistance was assessed as the proportion of damaged plants and damaged leaves, leaf feeding injury, and ...

Current Status of Tomato Chlorosis Virus and Whiteflies in Potato Crops of São Paulo State and Virus–Vector–Host Interactions

Plant Pathology, EarlyView.
ToCV is not widely distributed in potato crops in São Paulo, but its transmission by Bemisia tabaci MEAM1 and MED and its high vertical transmission rate highlight the need for monitoring to mitigate its potential future impact. ABSTRACT Potato is a vital food source worldwide, but its production is frequently threatened by viral diseases.
