DNAJA1 regulates protein ubiquitination and is essential for spermatogenesis in the testes of mice and rats.

DNAJA1 is a member of type I DnaJ proteins, which is essential for spermatogenesis and male fertility. However, its expression pattern in the testes and its impact on spermatogenesis remains unclear. Our study aimed to elucidate the mechanism of action of DNAJA1.

Exogenous melatonin enhances salt stress tolerance in maize seedlings by improving antioxidant and photosynthetic capacity.

Melatonin (N-acetyl-5-methoxytryptamine) is an important biological hormone in many abiotic stress responses and developmental processes. In this study, the protective roles of melatonin were investigated by measuring the antioxidant defense system and photosynthetic characteristics in maize under salt stress. The results indicated that NaCl treatment led to the decrease in plant growth, chlorophyll contents and photochemical activity of photosystem II (PSII).
