Phenolic exudates from orchid seeds as nutrients chemically attract fungi

Journal of Integrative Plant Biology, EarlyView.
Most orchid species require fungi for natural germination, but the molecular mechanism of this symbiosis is poorly understood. Cremastra appendiculata seeds secrete phenolic acids before fungal contact, acting as nutrient molecules to chemically attract its symbiotic fungus Coprinellus disseminatus.

Strigolactones affect the stomatal and transcriptomic memory of repeated drought stress in tomato

Plant Stress
Stress memory is an adaptive strategy for plants to cope with fluctuating environmental conditions. For example, it has been shown that the transcriptional responses to drought can be “trained”, i.e. changed, by a previous stress episode.

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

Journal 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 ...

Feedback-Regulation of Strigolactone Biosynthetic Genes and Strigolactone-Regulated Genes in Arabidopsis [PDF]

Bioscience, Biotechnology, and Biochemistry, 2009
Strigolactones (SLs) have recently been found to regulate shoot branching, but the functions of SLs at other stages of development and the regulation of SL-related gene expression are mostly unknown in Arabidopsis. In this study, we performed real-time reverse transcription-PCR (RT-PCR) and microarray analysis using wild-type plants and SL-deficient ...

Transcriptome analysis reveals that auxin promotes strigolactone-induced adventitious root growth in the hypocotyl of melon seedlings

Frontiers in Plant Science, 2023
IntroductionStrigolactone (SL) and auxin are two important phytohormones involved in plant root development, but whether they show synergistic or mutual promotion effects during adventitious root (AR) formation has not been adequately explored.MethodsIn ...

The homologous GRAS transcription factors RAM1 and RAD1 coordinate shared and separate gene networks to regulate arbuscular mycorrhiza symbiosis

New Phytologist, EarlyView.
Mutations in RAM1 and RAD1 have different effects on arbuscule development in Lotus japonicus. Summary Arbuscular mycorrhiza (AM), a symbiosis between plants and Glomeromycotan fungi is based on the exchange of nutrients, which majorly occurs between fungal tree‐shaped arbuscules and root cortex cells.

Triazole Ureas Covalently Bind to Strigolactone Receptor and Antagonize Strigolactone Responses [PDF]

Molecular Plant, 2019
Strigolactones, a class of plant hormones with multiple functions, mediate plant-plant and plant-microorganism communications in the rhizosphere. In this study, we developed potent strigolactone antagonists, which covalently bind to the strigolactone receptor D14, by preparing an array of triazole urea compounds.

Strigolactones modulate iron uptake in plants

New Phytologist, EarlyView.
Model for strigolactone regulation of basal iron uptake in Arabidopsis and maize. Summary Strigolactone (SL) hormones influence a wide range of developmental and physiological processes but have not previously been linked to plant iron homeostasis. Here, we identify the gene underlying the iron‐deficient maize mutant interveinal yellow (ivy) as ZmCCD8,

A Repertoire of Major Genes From Crop Wild Relatives for Breeding Disease‐Resistant Wheat, Rice, Maize, Soybean and Cotton Crops

Plant Breeding, EarlyView.
ABSTRACT Global food demand is predicted to rise anywhere from 59% to 98% by 2050 because of increasing population. However, the continued depletion of natural resources and increasing biotic and abiotic stresses will continue to pose significant threats to global food security in coming years.
