Quantitative patterns between plant volatile emissions induced by biotic stresses and the degree of damage [PDF]

open access: yesFrontiers in Plant Science, 2013
Plants have to cope with a plethora of biotic stresses such as herbivory and pathogen attacks throughout their life cycle. The biotic stresses typically trigger rapid emissions of volatile products of lipoxygenase pathway (LOX products, various C6 ...

Screening of pigeonpea (Cajanus cajan) mini-core germplasm sub-set for tolerance to wilt and pod borers

open access: yesThe Indian Journal of Agricultural Sciences, 2022
Biotic stresses are the major production constraints of pigeonpea crop including legume pod borer, spotted pod borer and pod fly and Fusarium wilt which cause significant yield losses.

Enhancing biocontrol potential of Trichogramma chilonis against borer pests of wheat and chickpea

open access: yesiScience, 2023
Summary: Communication between plants and herbivores occur mostly through chemicals. Plants emit volatiles in response to the attack of herbivores called herbivore-induced plant volatiles (HIPVs), which are employed by the plants to attract their ...

Functional characterization of Medicago truncatula GRAS7, a member of the GRAS family transcription factors, in response to abiotic stress

open access: yesBiotechnology & Biotechnological Equipment, 2022
Transcriptional factors play an essential role in the regulation of developmental processes in plants. GRAS family transcription factors are plant specific, and GRAS members possess multiple functions involved in plant growth and in response to abiotic ...

Bio-efficacy of sequential herbicide application for weed management in dry direct seeded rice

open access: yesThe Indian Journal of Agricultural Sciences, 2021
Weeds are the major biotic constraint in dry-direct seeded rice (DDSR), mainly due to the concurrent emergence and absence of water layer to suppress weeds.

Plant polyamines in stress and development: an emerging area of research in plant sciences. [PDF]

open access: yes, 2014
Compelling evidence indicates the participation of polyamines in abiotic and biotic stress responses in plants. Indeed, genetic engineering of polyamine levels in plants has successfully improved biotic and abiotic stress resistance in model plants and ...

A spotlight on non-host resistance to plant viruses [PDF]

open access: yesPeerJ, 2022
Plant viruses encounter a range of host defenses including non-host resistance (NHR), leading to the arrest of virus replication and movement in plants. Viruses have limited host ranges, and adaptation to a new host is an atypical phenomenon.

Emerging connections between small RNAs and phytohormones [PDF]

open access: yes, 2020
Small RNAs (sRNAs), mainly including miRNAs and siRNAs, are ubiquitous in eukaryotes. sRNAs mostly negatively regulate gene expression via (post-)transcriptional gene silencing through DNA methylation, mRNA cleavage, or translation inhibition.
