A number of N-methylproline analogues have been found to accumulate in different species of Tamarix. These include N-methyl-L-proline (MP), trans-4-hydroxy-N-methyl-L-proline (M4HP) and trans-3-hydroxy-N-methyl-L-proline (M3HP). The three compounds appeared in all species but their relative and absolute levels depend upon species, ecotype and level of applied salt stress. A salt-conditioned ecotype of T. jordanis (Sodom) dramatically increased its accumulation of all proline analogues when subject to salt stress whereas a non-saline ecotype (Gilboa) showed little effect. The levels of M4HP and M3HP in T. meyeri increased with increasing salt stress whereas MP levels remained almost constant.
已发现多种N-甲基脯氨酸类似物在不同柽柳属植物中积累。这些包括N-甲基-L-脯氨酸（MP）、反式-4-羟基-N-甲基-L-脯氨酸（M4HP）和反式-3-羟基-N-甲基-L-脯氨酸（M3HP）。这三种化合物在所有物种中均有出现，但它们的相对和绝对含量取决于物种、生态型和施加的盐胁迫水平。约旦柽柳（所多玛）的一种盐适应生态型在受到盐胁迫时，其所有脯氨酸类似物的积累量显著增加，而非盐生生态型（吉尔博亚）则几乎没有影响。迈耶柽柳中M4HP和M3HP的含量随着盐胁迫的增加而增加，而MP含量几乎保持不变。
