To better adapt transiently or lastingly to stimuli from the surrounding environment, the chromatin states in plant cells vary to allow the cells to fine-tune their transcriptional profiles. Modifications of chromatin states involve a wide range of post-transcriptional histone modifications, histone variants, DNA methylation, and activity of non-coding RNAs, which can epigenetically determine specific transcriptional outputs. Recent advances in the area of '-omics' of major crops have facilitated identification of epigenetic marks and their effect on plant response to environmental stresses. As most epigenetic mechanisms are known from studies in model plants, we summarize in this review recent epigenetic studies that may be important for improvement of crop adaptation and resilience to environmental changes, ultimately leading to the generation of stable climate-smart crops. This has paved the way for exploitation of epigenetic variation in crop breeding.

This study introduces a Drought Adaptation Index (DAI), derived from Best Linear Unbiased Prediction (BLUP), as a method to assess drought resilience in switchgrass ( L.). A panel of 404 genotypes was evaluated under drought-stressed (CV) and well-watered (UC) conditions over four consecutive years (2019-2022).

is the most widely cultivated high-protein forage crop globally. However, its cultivation in high-latitude and cold regions of China is significantly hindered by low-temperature stress, particularly impacting the root system, the primary functional tissue crucial for winter survival. The physiological and molecular mechanisms underlying the root system's adaptation and tolerance to low temperatures remain poorly understood.

4-Hydroxyphenylpyruvate dioxygenase (HPPD) plays a critical role in plant photosynthesis, and is essential for enhancing tolerance to oxidative stress. However, the precise mechanisms through which plants regulate HPPD in response to oxidative stress remain largely unknown. Here, we report that the Arabidopsis thaliana HPPD (AtHPPD) undergoes an uncharacterized post-translational modification, namely phenylalanine hydroxylation, in response to excessive hydroxyl radicals (·OH), thereby mediating oxidative stress tolerance.

Hybrid breeding based on male sterility requires the removal of male parents, which is time- and labor-intensive; however, the use of female sterile male parent can solve this problem. In the offspring of distant hybridization between Brassica oleracea and Brassica napus, we obtained a mutant, 5GH12-279, which not only fails to generate gynoecium (thereby causing female sterility) but also has serrated leaves that could be used as a phenotypic marker in seedling screening. Genetic analysis revealed that this trait was controlled by a single dominant gene.

Melon, a globally important horticultural crop, faces increasing continuous cropping obstacles (CCOs) due to cultivation intensification, with autotoxicity being a primary cause. Autotoxin accumulation severely impacts plant growth, reducing yield and quality. Exogenous silicon (Si) plays an important role in improving plant stress adaptation and is an environmentally friendly element with broad application prospects.
