Since the beginning of 21st century, climate change has been pervasive. Such climatic instabilities not only trigger plants' adaptability and survivability in harsh environments, but also sustain spread a broad spectrum pathogens including bacteria, fungi, viruses, that create disease pressure by affecting plant health immune barrier. Salicylic acid (SA) is potent phytohormone signaling molecule plays pivotal roles physio-biochemical processes during development. In addition to its widely known role abiotic stress response, SA vital response biotic stresses through their pathways, molecular interactions, corresponding interactions with other phytohormones like jasmonic acid, ethylene, abscisic etc. this perspective, dictated plethora interacting genes, proteins, transcription factors (TFs). The genes genetic regulators (TFs regulatory proteins) are associated fine-tune activating systemic localized cascade, triggering for pathogenesis-related (PR) phytoalexins, etc., modulate pathogen effectors. way, boosts plant's system acquired resistance (SAR) induced (ISR). addition, gene editing epigenetic regulation SA-responsive valuable innovative tools understand decipher complex SA-involved mechanism future utilities make climate-adaptive plants resistance.

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. Additionally, broadens its scope by examining response environmental stresses drought, salt, flood, heat, cold plants. compilation offers updated information insights guide characterization potential growth, development, resilience future research.

Low-temperature stress, including chilling and freezing injuries, significantly impacts plant growth in tropical temperate regions. Plants respond to cold stress by activating mechanisms that enhance tolerance, such as regulating photosynthesis, metabolism, protein pathways producing osmotic regulators antioxidants. Membrane stability is crucial, with cold-resistant plants exhibiting higher lipid unsaturation maintain fluidity normal metabolism. Low temperatures disrupt reactive oxygen species (ROS) leading oxidative damage, which mitigated antioxidant defenses. Hormonal regulation, involving ABA, auxin, gibberellins, others, further supports adaptation. also manage balance accumulating like proline sugars. Through complex regulatory pathways, the ICE1-CBF-COR cascade, optimize gene expression survive ensuring adaptability conditions. This study reviews recent advancements genetic engineering technologies aimed at enhancing resistance of agricultural crops. The goal provide insights for improving tolerance developing new cold-tolerant varieties.

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. Furthermore, specialized proteins, antifreeze proteins (AFPs) late embryogenesis abundant (LEA) play protecting cells during thawing. Despite its potential, faces significant challenges, standardizing protocols wide range species, especially those from tropical subtropical regions. review highlights importance ongoing research integration omics technologies improve techniques, ensuring their effectiveness across diverse species contributing efforts regarding conservation.
