Yunliu Zeng, first author of Sensory-directed Genetic & Biochemical Characterization of Volatile Terpene Production in Kiwifruit Current Position: Associate Professor at Huazhong Agricultural University (HZAU), China Education: Ph.D. and Master of Pomology at HZAU, China; BSc of Horticulture…

In C4 species, the expression of photosynthesis genes is partitioned such that leaf mesophyll and bundle sheath cells accumulate different components of the photosynthetic pathway. The expression of nucleus-encoded photosynthesis genes is modulated both by photoreceptor activity and by a network of…

Under hypoxia, Acetyl-CoA Synthetase (ACS), an enzyme that synthesizes acetyl CoA, recovers carbon that would otherwise be lost from the plant as ethanol. Plastid-localized ACS metabolizes cellular acetate and contributes to the de novo biosynthesis of fatty acids and Leu. On the other hand, a peroxisome-localized…

Zinc (Zn) is a metallic element that is essential for all living organisms. Zn serves as a catalytic or structural cofactor in a large number of enzymes including alcohol dehydrogenase, superoxide dismutase (SOD), and regulatory proteins such as transcription factors containing Z-finger domains. Accordingly,…

Secondary cell walls play important roles in providing long-distance water transport, mechanical support, and plant defense. The main components of secondary cell walls are cellulose, hemicellulose, and lignin. The synthesis of lignin monomers involves the phenylpropanoid pathway, which is also shared…

The elucidation of plant temperature signaling networks is confounded by the fact that commonly measured physiological outputs of temperature change (e.g., stem elongation and flowering time) can be temporally and spatially distant from the temperature perception event, requiring intercellular, intertissue,…

As a cold-hardy species, Arabidopsis (Arabidopsis thaliana), is a useful model for the investigation of the molecular and physiological mechanisms underlying cold acclimation in plants. Chloroplasts harbor the enzymatic machinery required for photosynthetic CO2 fixation, starch production, nitrite and…
