“…Peel browning is a main CI manifestation in refrigerated "Nanguo" pears during its shelf life, affecting the quality and reducing the commercial value of the pears 4 . The biomembrane is not only a barrier that protects cells from injury but also a primary location for sensing cold signals 10 . An increasing number of studies have reported that one of the main causes of CI is changes in membrane lipid composition, structure, and metabolic processes, which ultimately result in the degradation of cell membrane lipids 10 .…”

“…Phospholipids are fundamental molecules for establishing biological membranes and are highly conserved in bacteria, mammals, and seed plants 12 . The degradation of membrane lipids can destroy the structural integrity of the cytomembrane and lead to the disruption of cellular compartmentalization, resulting in enzymatic browning caused by the contact of phenolics with polyphenol oxidase 4,6,9,10,13 .

PuMYB21/PuMYB54 coordinate to activate PuPLDβ1 transcription during peel browning of cold-stored “Nanguo” pears

Refrigeration is commonly used to extend the storage life of "Nanguo" pears, but fruit in long-term refrigeration is prone to peel browning, which is related to membrane lipid degradation. To determine the mechanism of membrane lipid degradation, we identified two R2R3-MYB transcription factors (TFs), PuMYB21 and PuMYB54, from "Nanguo" pears, which were notably expressed in response to cold stress and during the peel-browning process. The results from yeast one-hybrid, electrophoretic mobility shift, and transient expression assays indicated that both PuMYB21 and PuMYB54 directly bind to the promoter of PuPLDβ1 (a key enzyme catalyzing the hydrolysis of membrane phospholipids) and activate its expression, which probably enhances the degradation of membrane phospholipids and eventually results in peel browning. Moreover, the overexpression of PuMYB21 and PuMYB54 can greatly activate the transcription of endogenous PuPLDβ1 in both "Nanguo" pear fruits and calli, and their silencing can inhibit its transcription. Furthermore, yeast two-hybrid, bimolecular fluorescence complementation, and pull-down assays verified that PuMYB21 interacts with PuMYB54 to enhance the expression of PuPLDβ1. In summary, we demonstrate that PuMYB21 and PuMYB54 may have roles in membrane lipid metabolism by directly binding to the downstream structural gene PuPLDβ1 during the low temperature-induced peel browning of "Nanguo" pears.

“…Increasing polyunsaturated fatty acid composition in seeds has been demonstrated to contribute in conferring cold or chilling tolerance in plants, particularly during seed germination. Scientific evidence that supports this contention can be found in literature on cold tolerance research on Arabidopsis thaliana, tobacco, corn, soybean, and peanuts [28,49,52,56,61]. In cotton, cold germination studies have been carried out as early as the 1960s, although the functional roles of fatty acid composition on the ability of cotton to germinate under low temperatures has not been fully explored [62,63].…”

Cotton is widely cultivated in temperate regions across the world and is often constrained by a short planting window that is bookended by low, suboptimal temperatures. With the growing interest in early season planting, improvements in the cold germination ability of cotton will be necessary to ensure the production stability of early planted crops. The importance of saturation levels of membrane and storage lipids in enhancing cold tolerance in plants, as well as improving cold germination ability in seeds have been widely researched in a range of plant species. While studies have shown that higher levels of unsaturated lipids can enhance cold germination ability and reduce seedling injury in other crops, similar efforts have been fairly limited in cotton. This review looks at the functional properties of membrane and storage lipids, and their role in membrane stability and reorganization during the early stages of germination. Additionally, the importance of storage lipid composition as an energy source to the growing embryo is described in the context of cellular energetics (i.e., fatty acid catabolism). Finally, perspectives in improving the cold germination of upland cotton by manipulating the fatty acid composition of both membrane and storage lipid content of seeds are presented.

Peanut (Arachis hypogea L.) yield is dramatically declined by extreme weather stresses under climate change. Adjusting the sowing date and plant density are effective strategies to mitigate these stresses and improve peanut yield. However, a mechanistic understanding of the influence of environmental drivers and an optimized strategy have yet to be developed. Here, a 3‐year field experiment was conducted to evaluate the sowing date (April 25, early sowing; May 5, middle sowing; May 15, late sowing) and plant density (24, 30, and 36 plants m−2 as low, medium, and high) of peanut in the North China Plain. We found that higher pod yield was observed in the middle sowing (∼4492.4 kg ha−1) compared with the early and late sowing (∼3317.2 and 4088.1 kg ha−1, respectively). Meanwhile, the pod yield in high density (∼4162.5 kg ha−1) was 10.6% and 4.7% higher than low and medium density, respectively, mainly due to higher leaf area index. The relative peanut pod yield was positively correlated with the average minimum temperature 5 days before and after the flowering pegging stage, whilst it was negatively correlated with average maximum temperature 5 days before and after pod filling stage. Therefore, optimizing temperature conditions to improve the peanut yield can be achieved by adjusting the sowing date. In conclusion, sowing date and plant density manipulation constitute a useful method to mitigate heat and chilling stress and improve peanut yield.
