Tomato Plant Cold Tolerance

The exposure of tomato plants to cold 4C increased the levels of HY5 MYB15 and CBFs transcripts. Tomatoes wherever they are grown demand mostly days in the 70sF 20sC to thrive and ripen.

Thus it is sensitive to cold.

Tomato plant cold tolerance. Resistance code definitions listed below. Elucidating the molecular mechanisms of tomato cold tolerance is critical for maintaining fruit quality and reducing postharvest losses. Tomato Lycopersicon esculentum Mill is an important food plant that has been used as a model plant in genetic evolution and molecular biology research.

Tomato Lycopersicon esculentum Mill plants which normally do not accumulate glycinebetaine GB are susceptible to chilling stress. The plant is originated from the tropics. One fact is certain.

The expression level of SlHY5 was similar in the root stem leaf flower and fruit of tomato. Tomato plants increase their chilling tolerance after exposure to suboptimal growth temperature Tomato plants subjected to 4C developed chlorosis and wilting symptoms after 5days and many of them died when LT treatment was prolonged for more than 10days Fig. A little research will reveal some cold-tolerant tomato.

The tomato seedlings wont germinate the young tomato plants will have stunted growth and the mature tomato plants wont produce fruit. Thats to say they set fruit in cooler temperatures and in many cases their fruits reach maturity in the shortest number of days possible. Nevertheless the functions of dehydration response factor DREB protein in plant cold tolerance especially in tomatoes Solanum lycopersicum have been rarely studied.

There are specific tomato varietals bred for cold hardiness which will tolerate conditions at or below 55 degrees F. But tomato plants can survive a cold snap or even a series of cool nights. A temperature below 32 F will cause frost that will kill the tomato plants and fruits.

Tolerate does not mean thrive. These tomatoes set fruit not only in cooler temps but also reach maturity in the shortest number of days. When the soil temperatures surpass 60ºF during the day then tomato roots will retain much of that heat even during an evening cool-down especially when plants are mulched.

Any temperature below 50 F is too cold for tomato plants. SlHY5 was upregulated gradually during cold stress and was induced in response to NaCl and the plant hormone abscisic acid. Moreover mutations in HY5 or MYB15 decreased the levels of CBF transcripts.

The transcription factor PHYTOCHROME-INTERACTING FACTOR4 PIF4 acts as a hub that integrates multiple signaling pathways to regulate thermosensory growth and architectural adaptation in plants. In this study the tomato HY5 gene SlHY5 was isolated and characterized with respect to its function in cold-stress tolerance. Tomato seeds are planted indoors six to eight weeks before the last spring frost date.

The best choices for colder climates are short to mid-season tomatoes. Exposure to temperatures below 10 degrees C 50 degrees F causes various injuries and greatly decreases fruit set in most cultivars. Cold Hardy Tomatoes.

Cold Weather Effects on Tomato Plants From link below. Tomatoes do NOT like to be cold. Cold-regulated gene LeCOR413PM2 confers cold stress tolerance in tomato plants Tomato Lycopersicon esculentum Mill is an important food plant that has been used as a model plant in genetic evolution and molecular biology research.

Here we provide evidence for the existence of a LONG HYPOCOTYL 5 HY5MYB15CBFs transcriptional cascade that plays a crucial role in the cold response in tomato. Check out these tomatoes that have a reputation for growing well in colder climates. Freezing temperatures retard the germination of the seeds and.

In this study the functions of tomato DREB TF SlDREB3 in cold resistance were studied using transgenic tomatoes. The best tomatoes for cold climates are short- to mid-season tomatoes. Plants have a wide range of defense mechanisms against severe environmental changes including heat shock proteins HSPs.

5 rows Cold Tolerant Tomato Plants. Chilling injury tolerance is associated with the ability to accumulate HSPs 2. Here we report that SlPIF4 in tomato Solanum lycopersicum plays a pivotal role in regulating cold tolerance in anthers.

The plant is originated from the tropics. Where the growing season is short you want to grow tomatoes that have fewer days to maturity and those that can tolerate chilly temperaturesmeaning temperatures in the mid to high 50sF and 60sF 15-16sC. Its growth and development can be easily affected by cold stress.
