Chlorantraniliprole: bioactivation in coffee seedlings and control of resistant Leucoptera coffeella populations

open access: yesPest Management Science, EarlyView.
Chlorantraniliprole enhanced growth and biomass in coffee seedlings infested by susceptible Leucoptera coffeella, while resistant populations limited its insecticidal performance. These findings emphasize both the bioactivator potential of chlorantraniliprole and the challenges of managing resistance in coffee leaf miner control.

Single-cell transcriptome sequencing reveals the sphingolipid metabolism pathway plays an important role in leaf senescence in tobacco

open access: yesBMC Plant Biology
Tobacco was an important cash crop and model plant, and the senescence (yellowing) of its leaves were essential markers of harvesting and secondary metabolite formation.

Effects of Heavy Metal: Copper on the Ultrastructure of Wheat

open access: yesChemical Engineering Transactions, 2017
Copper was one of common soil contaminants in China. In order to research the stress mechanism of copper to wheat, the structure of subcellular in mesophyll cell were studied at different copper concentration and growth stage in natural conditions.

Efficient water‐soluble blue/red‐emissive carbon dots matching plant absorption spectra: Synthesis, tunable control, and their applications in promoting plant growth

open access: yesResponsive Materials, EarlyView.
Guided by the spectral demand of plant photosystems, this review summarizes the synthesis, emission regulation, dual‐emission design, and gram‐scale production of CDs for agricultural applications. Spectrally matched blue‐ and red‐emissive CDs enhance plant light utilization by converting underutilized light into photosynthetically active radiation and

Hemipteran vectors of stylet‐borne plant viruses: Aphids lead the charge

open access: yesInsect Science, EarlyView.
Among all sap‐feeding hemipterans, aphids stand out by far as the most important vectors of noncirculative plant viruses. Compared to whiteflies and mealybugs, aphids’ highly specialized stylet anatomy and distinct feeding behaviors contribute, together with other features of their biology, to their remarkable efficiency in transmitting stylet‐borne ...

Structure of Kalanchoë pumila Bak. leaves (Crassulaceae DC.)

open access: yesActa Agrobotanica, 2012
The structure of Kalanchoё pumila Bak. was studied with the use of stereoscopic, light, scanning and transmission electron microscopy. It was found that the chlorenchymatic tissue was divided into subepidermal small-celled mesophyll and large-celled ...

A defensive symbiont and a plant virus confer direct and discrete phenotypes to a cereal aphid in a context‐dependent manner

open access: yesEcological Entomology, EarlyView.
Different BYDV‐PAV isolates exert contrasting effects on aphid fitness, including reproduction and winged production. Different BYDV‐PAV isolates have contrasting effects on aphid dispersal patterns. Aphid feeding behaviour is modulated by the presence of endosymbionts and plant viruses.

C‐type cyclin CycC1;1 delays leaf senescence by interacting with and inhibiting MYC2 in Arabidopsis

open access: yesJournal of Integrative Plant Biology, EarlyView.
The C‐type cyclin CycC1;1 interacts with MYC2 and MED25 to block their association and RNA polymerase II recruitment, thereby repressing senescence‐associated gene expression and delaying leaf senescence in Arabidopsis. Unlike jasmonic acid‐inducible JAZ repressors, CycC1;1 operates independently of jasmonic acid signaling, representing an ...

Ultrastructural Development of Mesophyll Cells in Rice Seedlings

open access: yesJapanese Journal of Crop Science, 1977
Ultrastructural observations were made on the mesophyll cells in leaves at different stages of development. In the ground meristem of the leaf primordium, the plastids and mitochondria, both are approximately the same in dimention, locate around the large nucleus (Fig. 1). The plastids contain several lamellae and small starch grains (Fig. 4).

Drought and salinity stress remodel Asian rice (Oryza sativa) leaf development through cell‐type‐specific regulatory programs

open access: yesNew Phytologist, EarlyView.
Osmotic stressors induce developmental and physiological changes in rice (Oryza sativa) seedlings, which are modulated by cell‐type‐specific gene expression and regulatory networks. We exposed plants to two levels of drought and salinity stress and measured the effects of these stressors on developing leaves by measuring physiological traits, ion ...
