Soil salinization, which is the accumulation of salt in soil, can have a negative impact on crop growth and development by creating an osmotic stress that can reduce water uptake and cause ion ...toxicity. The NHX gene family plays an important role in plant response to salt stress by encoding for Na
/H
antiporters that help regulate the transport of sodium ions across cellular membranes. In this study, we identified 26
genes in three cultivars of
L., including 9
, 9
(
) and 8
(
). The evolutionary tree splits the 21
genes into three subfamilies: the endosome (Endo) subfamily, the plasma membrane (PM) subfamily, and the vacuole (Vac) subfamily. All the
genes were irregularly distributed throughout the 21 chromosomes. 26
were examined for conserved motifs and intron-exon organization. These findings suggested that the genes in the same subfamily may have similar functions while genes in other subfamilies may have functional diversity. The circular phylogenetic tree and collinearity analysis of multi-species revealed that
L. had a substantially greater homology relationship than
and
in terms of
gene homology. We initially examined the
-acting elements of the 26
in order to investigate how they responded to salt stress. We discovered that the
,
,
,
,
, and
all had numerous ABRE and G-box
-acting elements that were important to salt stress. Previous transcriptome data showed that in the mesophyll and veins of leaves, many
and
, such as
, responded significantly to salt stress. In addition, we heterologously expressed in
plants in order to further confirm the response of
to salt stress. The findings demonstrated that during salt stress,
that had
heterologously expression was found to have decreased salt tolerance. This study offers important details that will aid in further elucidating the molecular mechanism of
under salt stress.
In this review, the experience of Russian and foreign scientists in field of development of technology of doubled haploids (DHs) of Cucurbitaceae crops is summarized. The different factors affected ...on the development of DH-plants and the ways of increasing of yield of double haploids are described in the article.
The first part, consisting of seven files, reviews current knowledge about direct covers as used in climate and pest control. The second part of the work consists of 26 crop data sheets offering ...practical advice on the use of direct covers for specific vegetables based on the characteristics of each species. The vegetable crops are the following. Bulbous vegetables: fennel, onion; green and stem vegetables: swiss chard, chicory, Chinese cabbages, head cabbages, kohlrabi, endive, lettuce, corn salad, parsley, leek; flower vegetables: broccoli, cauliflower; fruit vegetables: courgette, gherkin, strawberry, common bean, muskmelon, tomato; root and tuber vegetables: beetroot, carrot, celeriac, turnip, potato, radish
