Functional identification of apple MdJAZ2 in Arabidopsis with reduced JA-sensitivity and increased stress tolerance.

Here, we report the decrease of JA-sensitivity and enhancement of tolerance to salt and PEG stresses in Arabidopsis overexpressing apple MdJAZ2. As signalling molecules, jasmonates (JAs) play significant roles in plant development and stress responses. JAZ proteins are the targets of the SCF complex and act as the negative regulators in JA signalling pathway.

[Physiological and biochemical responses of different scion/rootstock combinations grapevine to partial rootzone drought].

By using self-made wooden boxes with two separated zones, the grapevine Vitis vinifera cv. Malvasia (M) grafted on rootstocks 3309C, 420A and 110R, respectively, was planted, and the physiological and biochemical responses of these scion/rootstock combinations to bilateral alternative irrigation (AI) and unilateral irrigation (UI) were studied. The results showed that in treatments AI and UI, the average leaf ABA content of test scion/rootstock combinations increased by 267.

[Changing characteristics of temperature and humidity in different type bags for bagging apple and their effects on fruit appearance quality].

This paper studied the changing characteristics of temperature and humidity in different type bags for bagging Fuji apple during its development and their effects on the appearance quality of the fruit. The results showed that there was a negative correlation between the changes of temperature and humidity in the bags. Temperature started to rise rapidly from 9:00, with the highest appeared generally from 13:00 to 14:00 in spring and autumn or from 13:00 to 17:00 in mid-summer, while the lowest at about 5:00.
