Plant species utilize a variety of regulatory mechanisms to ensure sustainable productivity. Within this intricate framework, numerous non-coding RNAs (ncRNAs) play crucial role in plant biology, surpassing the essential functions RNA molecules as messengers, ribosomal, and transfer RNAs. ncRNAs represent an emerging class regulators, operating directly form small interfering (siRNAs), microRNAs (miRNAs), long noncoding (lncRNAs), circular (circRNAs). These exert control at various levels, including transcription, post-transcription, translation, epigenetic. Furthermore, they interact with each other, contributing biological processes associated stress resilience. This review primarily concentrates on recent advancements ncRNAs, delineating their growth development across organs such root, leaf, seed/endosperm, seed nutrient development.

Long non-coding RNA (lncRNA) plays important roles in animals and plants. In filamentous fungi, however, their biological function infection stage has been poorly studied. Here, we investigated the landscape regulation of lncRNA plant pathogenic fungus Botrytis cinerea by strand-specific RNA-seq multiple stages. total, 1837 lncRNAs have identified B. cinerea. A large number were found to be antisense mRNAs, forming 743 sense-antisense pairs, which 55 respective sense transcripts induced parallel as stage. Although small RNAs produced from these overlapping loci, appeared not involved gene silencing pathways. addition, alternative splicing events occurred lncRNA. These results highlight developmental stage-specific nature functional potential expression provide fundamental resources for studying stage-induced lncRNAs.

Cryopreservation is a crucial technique for the long-term ex situ conservation of plant genetic resources, particularly in context global biodiversity decline. This process entails freezing biological material at ultra-low temperatures using liquid nitrogen, which effectively halts metabolic activities and preserves tissues over extended periods. Over past seven decades, plethora techniques cryopreserving materials have been developed. These include slow freezing, vitrification, encapsulation dehydration, encapsulation–vitrification, droplet cryo-plates, cryo-mesh techniques. A key challenge advancement cryopreservation lies our ability to understand molecular processes underlying tolerance. mechanisms cold acclimatization, activation cold-responsive genes through pathways such as ICE–CBF–COR cascade, protective roles transcription factors, non-coding RNAs, epigenetic modifications.

Introduction Earlier sowing is a promising strategy of ensuring sufficiently high maize yields in the face negative environmental factors caused by climate change. However, it leads to low temperature exposure plants during emergence, warranting better understanding their response and acclimation suboptimal temperatures. Materials Methods To achieve this goal, whole transcriptome sequencing was performed on two inbred lines – tolerant/susceptible temperatures, at 5-day-old seedling stage. Sampling after 6h 24h treatment (10/8°C). The data filtered, mapped, identified mRNAs, lncRNAs, circRNAs were quantified. Expression patterns RNAs, as well interactions between them, analyzed reveal ones important for low-temperature response. Results Discussion Genes involved different steps photosynthesis downregulated both genotypes: psa, psb, lhc , cab genes photosystem I II functioning, rca, prk, rbcx1 necessary Calvin cycle. difference tolerance genotypes appeared arise from ability mitigate damage photoinhibition: ctpa2, grx, elip, UF3GT showed higher expression tolerant genotype. Certain lncRNAs also targeted these genes, creating an interaction network induced (XLOC_016169- rca ; XLOC_002167-XLOC_006091- elip2 ). These findings shed light potential mechanisms emergence lay groundwork subsequent analyses across diverse developmental stages. As such, offers valuable guidance future research directions molecular breeding maize.
