We examined rice response to interrupted (night or day) N supply. Root N uptake increased in both groups compared with continuously fed plants after 3 days of treatment. The magnitude of the increase was greater with daytime feeding.

Water conservation strategy allows the crop to use soil water to extend over a longer period of time and has water available during the critical phase of seed filling. The present study integrated the water use patterns in vegetative and early productive stages of different canola (Brassica napus L.) genotypes. The genotype with conservative water use could be utilized in agronomy production and breeding improvement for canola in drought-prone ecosystem.

As unique signal molecules, nitric oxide (NO) and hydrogen sulfide (H₂S) have broad application prospects in biology. Here, we focus on how NO is involved in H₂S-induced adventitious rooting, by regulating rooting-related enzyme activity and their gene expression as well as nutrient substance content. With its promising application in plants, NO and H₂S will be welcomed in horticultural plant growth and development.

Environmental changes expose plants to stressful conditions such as drought. Some symbioses between plants and fungus can confer tolerance to deal with it. We investigated the ecophysiological mechanisms by which the fungus Epichloë occultans interacts with Lolium multiflorum when increasingwater deficit and we found that fungus can modify water use, adjusting leaves and roots and modifying carbon plant allocation. A moderate water stress could increase the effectiveness of mutualism, guaranteeing this symbiosis and mitigating global change impacts on plants.

The maximum K solubilisation colony was identified as Burkholderia sp. by biochemistry and molecular analysis. Tartaric acid and pryuvic acid produced by Burkholderia sp. are important components associated with K solubilisation in vitro. The inoculation of Burkholderia sp. significantly improved soil available K level, tea (Camellia sinesis L.) plant height and total polyphenols content in pot experiment. Burkholderia sp.-promoted higher production of polyphenol, which may be attributed by its higher available K level in soil.

Water-deficit conditions on habanero pepper in an arid environment change morphometric but not change physiological parameters. Stress-related transcription factors (HSFs, MYB72, ETR1, WRKY72) and genes (HSPs, Jar1, Lox2) were directly involved in the response to water-deficit stress conditions in an arid environment. The results can help improve our understanding of mechanisms underlying water-deficit stress response in C. chinense in an arid environment and assist development of novel stress-tolerant pepper cultivars addressing climatic changes derived from global warming.

Stomatal traits regulate the physiological processes in plants. Yet, the variation of stomatal characteristics among different functional groups of trees has not been adequately understood. We provide evidence that leaf stomatal characteristics differ among trees of different functional groups and leaf phenological characteristics. The well-known trade-off between stomatal size and density varies with plant functional types. Our findings suggest that leaf phenology and species shade tolerance should be considered while estimating gas exchange through the stomata in tropical moist forests.
