Inferring the Potential Geographic Distribution and Reasons for the Endangered Status of the Tree Fern, Sphaeropteris lepifera, in Lingnan, China Using a Small Sample Size

Horticulturae, 2021
In this study, we investigated suitable habitats for the endangered tree fern, Sphaeropteris lepifera (J. Sm. ex Hook.) R.M. Tryon, based on fieldwork, ecological niche modeling, and regression approaches. We combined these data with the characterization

Functional variation in phyllogen, a phyllody‐inducing phytoplasma effector family, attributable to a single amino acid polymorphism

Molecular Plant Pathology, Volume 21, Issue 10, Page 1322-1336, October 2020., 2020
Comparison of phyllogen, a phyllody‐inducing effector family, revealed its molecular evolution and functional variation attributed to a single amino acid polymorphism governing the phyllody symptoms of phytoplasma infection. Abstract Flower malformation represented by phyllody is a common symptom of phytoplasma infection induced by a novel family of ...

Tobacco mosaic virus and the virescence of biotechnology [PDF]

Philosophical Transactions of the Royal Society of London. Series B: Biological Sciences, 1999
There is a growing realization that a modern combination of molecular biology and agriculture will provide a photosynthetic basis for the biosynthesis of an increasing variety of complex and valuable molecules. This ‘greening’ of biotechnology may impact on the global environment in many beneficial ways, but will perhaps have its most significant ...

Pest categorisation of the non‐EU phytoplasmas of Cydonia Mill., Fragaria L., Malus Mill., Prunus L., Pyrus L., Ribes L., Rubus L. and Vitis L.

EFSA Journal, Volume 18, Issue 1, January 2020., 2020
Abstract Following a request from the European Commission, the EFSA Panel on Plant Health performed a pest categorisation of nine phytoplasmas of Cydonia Mill., Fragaria L., Malus Mill., Prunus L., Pyrus L., Ribes L., Rubus L. and Vitis L. (hereafter “host plants”) known to occur only outside the EU or having a limited presence in the EU.

Life table studies of Trilocha virescence (Bombycidae: lepidoptera) on Ficus nitida [PDF]

Asian Journal of Agriculture and Biology, 2013
The life table of Trilocha virescence was constructed in the laboratory which is a serious Lepidopterous pest of Ficus nitida. The study declared different impact of larval and adult mortality on the population.

Nuclear Gene Affecting Greening in Virescent Peanut Leaves [PDF]

Plant Physiology, 1972
Chlorophyll synthesis induced by continuous illumination of dark-grown seedlings has been followed in wild-type and virescent peanut leaves. Compared to the wild-type leaves, chlorophyll synthesis in the virescent leaves shows a 72-hour lag period before the onset of a phase of rapid chlorophyll accumulation.

Molecular characterization of effector protein SAP54 in Bellis virescence phytoplasma (16SrIII-J)

, 2019
Phytoplasmas are wall-less bacteria with a parasitic lifestyle responsible for numerous plant diseases worldwide. Since the introduction of next generation sequencing technologies, genome wide studies of these pathogens are flourishing and a handful of ...

Effects of Phytoplasma Infection on Aster Leafhopper (Macrosteles quadrilineatus) Settling Behavior and Development on Brassica napus

Entomologia Experimentalis et Applicata, Volume 174, Issue 2, Page 132-141, February 2026.
Aster yellows phytoplasma (AYp) infection alters host plant preference in aster leafhoppers (Macrosteles quadrilineatus), with infected vectors showing a significant preference for AYp‐infected canola (Brassica napus) early in the infection period. However, this preference fades as infection progresses. Despite early attraction, B.

Phytoplasma-Induced Floral Abnormalities in Catharanthus roseus Are Associated with Phytoplasma Accumulation and Transcript Repression of Floral Organ Identity Genes

Molecular Plant-Microbe Interactions, 2011
Floral symptoms caused by phytoplasma largely resemble floral reversion in other plants. Periwinkle leaf yellowing (PLY) phytoplasma and peanut witches'-broom (PnWB) phytoplasma caused different degrees of floral abnormalities on infected periwinkle ...
